Just as you would not train 100 meter sprinter with the same protocol as a marathoner, likewise you would not train all cyclists with the same protocol. If you have ever followed the Tour De France closely you will have noticed that the cyclists who are winning the flat stage races in blazing 40+ mph sprints over the last 200 meters are not the same cyclists winning the long 150 mile mountain stages. The most powerful cyclists in the Tour De France are the sprinters who are capable of generating 1600-1800 watts of power during a short 200 meter sprinting. These same powerful sprinters are nowhere to be seen once the race gets into the mountains and do all that they can to be able to finish the race. When it comes to bicycle racing the track sprinters who generally race 1/4 mile are heavy into resistance training especially for their lower body strength. Generally the shorter and the flatter the race course the more absolute power comes into play on the other hand the longer and the hillier the race the more endurance and high VO2 max comes into play. I have been cycling for the past 20 years and up until 10 years ago I also did some bicycle racing. I have relatively powerful legs and have no trouble squatting sets of 400+lbs. In a flat Criterium I can generally hold my own but once a race goes from flat racing to hill climbing I find myself struggling at the back of the pack while the guys with the " skinny " legs fly up the hill. If a cyclist plans on racing on courses that have hills they are better off doing their strength training on the bike rather than in the gym. The best strength training on the bike is to find a hill of 1+ mile in length and do climbing intervals. Some cyclists have been known to add weights to their bike to increase the strength training effect. Why the hills and not the gym? First of all because it is very specific to what the athlete needs. No matter how hard you try there is no way to use weights in a way that will strength the muscles in a manner mimicking the sequential firing of muscles in a single rotation of the pedal stroke. Secondly in riding up a 1 mile hill the cyclist pedaling at 60 rpm will probably perform 300 repetitions at 300-400 watts. If he/she climbs the hill 10 times in a training session that is 3000 reps. I don't think that you can duplicate that in a gym. Is there a role for resistance training for the endurance cyclists? Certainly but for general conditioning in the off season, but only as long as the training does not bring about hypertrophy. The cyclists spend thousands of dollars to purchase the lightest bikes they can afford and the extra weight especially in the upper body will negate any advantage a light bike will give them especially in the mountains. ********************* " An additional factor in Lance's improvement over the years is that he has learned how to reduce his body weight and body fat by 10 pounds (5 kg) prior to each of his victories in the Tour de France. Therefore, over all his power per kg of body weight has increased a 18% while climbing-up the steep mountains in France. " ( Lance Armstrong's Physiological Maturation F. Coyle, Ph.D.; ProfessorDirector, Human Performance Laboratory ) ***************** Just as the wrong type endurance training can an adverse effect on a competitive weight lifter likewise the wrong type of resistance training can have an adverse effect on a competitive cyclists.

The following article from Carmichael Training System website may shed some light on this question: Ralph Giarnella MD Southington Ct, USA ************************************ The Creatine Question By Kendig, CTS Sports Dietitian Question: I am a new cyclist, training for the MS 150. A few of my buddies have been taking creatine to improve their strength. Is this something that will help me get through my goal event? — Bob H., via e-mail Answer:Good question, Bob. Creatine is one of the most studied sports nutrition supplements around with hundreds of studies having been published on it's efficacy. The majority of them have focused on the performance enhancing effects of the stuff. What is creatine? Creatine is a substance that is naturally produced in the liver and kidneys and is stored mostly in the muscles, heart, and other body cells. Once in the cellular realm it morphs into creatine phosphate, a compound utilized for energy production. Creatine phosphate is used to fuel any activity that requires short, fast bursts of power such as weight training. This supplement is also used as a recovery aid since it replenishes your cellular reserves of ATP, the fuel that provides the power for muscle contractions. But as a cyclist and an endurance athlete, here’s what you need to know: Research shows that any benefit to endurance exercise is absent or inconsistent. Performance in sports such as running, cycling, cross-country skiing, and swimming does not improve with muscle mass gains, and performance can actually be hindered with the decrease in flexibility and water retention. (Several studies on creatine use demonstrated increases in water weight gain and muscle cramping in test subjects.) Does it work? The answer depends on the athlete. Creatine has indeed been shown to improve performance in athletes that involve repeated short bursts of high intensity activity — Football, baseball players, and weight lifters do benefit. In addition, active professionals, such as firefighters, police officers, and construction workers might also find creatine helpful in their daily activities as they engage in quick tasks involving bursts of power. But for runners, cyclists, and triathletes, the current research suggests that it’s not worth the time or money to use the supplement.

Guest guest Posted January 11, 2007 Report Share Posted January 11, 2007 Performance in endurance sports does not benefit from weight gains, but weight gains are not necessarily the caused by proper weight lifting particularly among endurance athletes. Most endurance athletes are the guys who have a hard time gaining weight no matter what they do. Those who can put on weight quickly tend to be built like the sprinters and, therefore, are the sprinters. Because we rarely see competitive weight lifting on television and when we do it is only the heavyweights (or body builders) we tend to forget that weightlifting is a sport comprised of weight classifications. There are very light weightlifters who are incredibly strong. They would have little reason to want to gain weight and get moved up to the bottome of the next weight class. In an effort to avoid gaining weight, some endurance athletes lift light weights. Thinking they want to improve strength endurance, they do lots of reps or sets. This is more in line with classic body building regimes where the goal is to gain mass. They would probably be better off lifting more like Olympic lifters in terms of using heavy weights and few reps. I would expect that endurance runners and endurance cyclists would not reap the same benefits from the strength gains of heavy weight lifting since the activities are quite different.

" This topic has been debated here several times before. The people who participate on this forum tend to be much more knowledgeable in strength training than endurance training, so it seems to be no coincidence that the folks here are pretty sympathetic to the idea that increasing strength will increase endurance performance. However, if you go to the google group on wattage (a cycling discussion group) and raise this topic, you'll find that this idea enjoys much less acceptance among the people there who have studied endurance performance. That said, here are some thoughts. The following qotations are from the article at http://www.titansportsperformance.com/missinglink.html > However as a cycling coach and strength and conditioning coach > the goal in training the endurance athlete is producing greater > amounts of sustainable power.

Okay, but why would non-specific exercise such as strength training be more effective at doing this than the specific endurance task itself? After years of participating in these debates, I have yet to hear a scientific explanation for this. This article is a perfect example of a person repeatedly making the assertion that strength training improves endurance performance without offering any support for it. > For example, > if during a long duration tempo ride (65-75% of VO2 max) the athlete > is able to produce a greater amount of average power without > exceeding the prescribed intensity the athlete will receives a > greater overload during the same duration of time. Well, that gets it exactly backwards. If the athlete is able to produce a greater power output (relative to previous performances) at the same percentage of VO2max, then the athlete has *demonstrated* a performance increase. However, if the athlete used to be able to maintain, e.g., 240 watts at 70% VO2max for three hours and is now able to maintain, e.g., 250 watts at 70% VO2max for three hours, then a three hour ride at 250 watts is not an " overload " at all--it's still a three hour ride at 70% of VO2 max. It is merely maintaining the new status quo. It's also worth mentioning that 60-70% of VO2max isn't a " tempo " workout at all, and that we really should be looking at a percentage of VO2 at lactate threshhold or OBLA, and not a percentage of VO2max. I mention these ideas only briefly to show that the author of this article doesn't really know what he's talking about. > Properly managed resistance > training provides the athlete the ability to generate higher levels > of sustainable power throughout sport specific training sessions. Based on what theory or scientific evidence?

Very vague, but if we assume he means that the use of resistance training can increase power production in endurance sports, then he's once again making this assertion without offering any support for it. > In many cases the exercise protocol prescribe for endurance athletes > leans more toward hypertrophy which will in the short run produce > lower performance in most endurance training programs.

Exactly. Notice how the author never explains how to design a resistance training program that gets around this problem. > Most endurance sport > performance is driven by the ability to sustain maximum power.... Wrong. During endurance sport performance, muscles are working at a fairly low percentage of maximum power--not even at VO2max. > The goal in endurance training typically focuses on improving the > maximum oxygen delivery (VO2 max) and the ability to efficiently > utilize the oxygen that is being delivered.

Yes, like maybe the athlete should be training to increase power at LT/OBLA instead of power at and above VO2max. Again, how would strength training increase power at LT/OBLA? The author never explains this. > THE MISSING LINK: > > A CYCLIST AS AN EXAMPLE > > THE REAL MEASUREMENT OF A GOOD RESISTANCE TRAINING PROGRAM FOR A > CYCLIST OR OTHER ENDURANCE ATHLETE IS THAT IT CREATES A PLATFORM FOR > THE ATHLETE TO PRODUCE GREATER POWER OUTPUT DURING SPORTS SPECIFIC > TRAINING SESSIONS.

Did you see the author " put the rabbit into the hat " there?

Notice the author misspells " Noakes " and doesn't provide any citation at all for his proposition that the trend observed by Dr. Noakes continues. It's also important to note the lack of logic here in attributing continuing increases in endurance performance to the discontinued short-term strength program instead of the long-term, continuing endurance training. > SUMMARY: > > 1) Research shows that resistance training aids endurance athletes.

What kind of power development? Maximum power? Power at VO2max? Power at LT or OBLA? And how does resistance training improve the latter two?

This assertion was never discussed earlier in the article, so why is it in the summary? Notice also that the author does not even bother to support it.

Guest guest Posted January 12, 2007 Report Share Posted January 12, 2007 It seems that coaching bias plays a big role in the discussion of this matter. Being a former Cat 1 road cyclist and a current strength coach, I hear it from both sides. Some of the feedback I've received is that yes, it does help, although not nearly as much with trained cyclists (per se) and that the hard data on the matter is sparse. A Pub Med search did well to find research but most was relative to endurance nordic skiing performance. Most of those studies concluded that max strength and power training did in fact improve the skiers endurance performance. Another coach told me that once an effort level falls below 30% of maximum, improving the maximum will not effect the economy at that (below 30%) level. This makes sense to me on an intuitive level but I haven't seen any research supporting it. My empirical evidence is that it does improve certain aspects of bicycle racing, sprints, accelerations, jumps, starts, etc. Again, I don't have hard data but the subjective feedback I get from riders is that these tasks seem easier. The exercises we tend to use are olympic variations, squats and deadlifts (for instance) with reps anywhere in the 2-7 range with 5-10 sets with usually 3-5 minutes of rest between sets. I realize these acute variables are actually not so acute but are presented merely as insight into our programs. I feel like improving performance at lower intensities is generally best done on the bike. I haven't found a way to train at as high of intensity (percentage of max strength and power, not heart rate) on the bike as I can in the weight room.

Guest guest Posted January 12, 2007 Report Share Posted January 12, 2007 Here's some references to the strength training and endurance performance: Maximal strength training improves work economy in trained female cross-country skiers. Applied Sciences Medicine & Science in Sports & Exercise. 31(6):870-877, June 1999. HOFF, JAN; HELGERUD, JAN; WISLOFF, ULRIK Abstract: Maximal strength training improves work economy in trained female cross-country skiers. Med. Sci. Sports Exerc., Vol. 31, No. 6, pp. 870-877, 1999. Purpose: The present study examines the hypothesis that maximal strength training improves work economy and anaerobic threshold in trained female cross-country skiers while working on a ski ergometer. Methods: Fifteen female cross-country skiers (17.9 +/- 0.3 yr, 166.7 +/- 1.3 cm, 60.1 +/- 1.9 kg, and 55.3 +/- 1.3 mL[middle dot]kg-1 [middle dot]min-1) participated in the study. Eight skiers made up the high-intensity strength-trained group, and seven served as the control group. Endurance performance was tested on a specially instrumented ski ergometer. Strength training and testing simulated double poling in cross-country skiing. Results: A significant (P < 0.001) improvement in double-poling economy on the ski ergometer was observed among the strength-trained group. Anaerobic threshold did not change during the experimental period for either group. After a 9-wk training period, time to exhaustion increased from 5.2 (+/-0.9) to 12.3 (+/-1.6) min (P < 0.001) and from 4.0 (+/-0.9) to 6.3 (+/-0.9) min (P < 0.01) for the strength and control group, respectively. Time to exhaustion was significantly higher (P < 0.001) for the strength group compared with the control group after training. One repetition maximum increased 14.5% (1.8) (P < 0.001) in the strength group but was unchanged in the control group. Expressed in relation to peak force at one repetition maximum, strength training resulted in a significant reduction in the relative available force employed working on the ski ergometer (P < 0.01). Time to peak force at maximal aerobic velocity on the ski ergometer was significantly reduced in the strength- training group (P < 0.01). Conclusions: It is concluded that maximal strength training in the upper-body improved the double-poling performance by improved work economy. Work economy was improved by a reduction in relative workload and time to peak force while double poling. Maximal Leg-Strength Training Improves Cycling Economy in Previously Untrained Men. Applied Sciences Medicine & Science in Sports & Exercise. 37(7):1231-1236, July 2005. LOVELESS, DANIELLE J.; WEBER, CLARE L.; HASELER, LUKE J.; SCHNEIDER, DONALD A. Abstract: Purpose: This study examined cycling economy before and after 8 wk of maximal leg-strength training. Methods: Seven previously untrained males (25 +/- 2 yr) performed leg- strength training 3 d[middle dot]wk-1 for 8 wk using four sets of five repetitions at 85% of one repetition maximum (1RM). Body mass, lean-leg muscle mass (LLM), percentage of body fat, and leg strength (1RM) were measured at 0, 4, and 8 wk of training. Cycling economy was calculated as the [DELTA][latin capital V with dot above]O2/ [DELTA]WR (change in the O2 cost of exercise divided by the change in the power between two different power outputs). Results: There were significant increases in LLM and 1RM from 0 to 4 wk of training (LLM: 25.8 +/- 0.7 to 27.2 +/- 0.8 kg; 1RM: 138 +/- 9 to 215 +/- 9 kg). From 4 to 8 wk of training, 1RM continued to increase significantly (215 +/- 9 to 266 +/- 8 kg) with no further change observed in LLM. Peak power during incremental cycling increased significantly (305 +/- 14 to 315 +/- 16 W), whereas the power output achieved at the gas-exchange threshold (GET) remained unchanged. Peak O2 uptake and the O2 uptake achieved at the GET also remained unchanged following training. Cycling economy improved significantly when the power output was increased from below the GET to above the GET but not for power outputs below the GET. Conclusion: Maximal leg-strength training improves cycling economy in previously untrained subjects. Increases in leg strength during the final 4 wk of training with unchanged LLM suggest that neural adaptations were present. Med Sci Sports Exerc. 1999 Jun;31(6):886-91.

PURPOSE: The purpose of this study was to determine the effects of resistance training on endurance performance and selected muscle characteristics of female cyclists. METHODS: Twenty-one endurance- trained, female cyclists, aged 18-42 yr, were randomly assigned to either a resistance training (RT; N = 14) or a control group (CON; N = 7). Resistance training (2X x wk(-1)) consisted of five sets to failure (2-8 RM) of parallel squats for 12 wk. Before and immediately after the resistance-training period, all subjects completed an incremental cycle test to allow determination of both their lactate threshold (LT) and peak oxygen consumption VO2). In addition, endurance performance was assessed by average power output during a 1- h cycle test (OHT), and leg strength was measured by recording the subject's one repetition maximum (1 RM) concentric squat. Before and after the 12-wk training program, resting muscle was sampled by needle biopsy from m. vastus lateralis and analyzed for fiber type diameter, fiber type percentage, and the activities of 2-oxoglutarate dehydrogenase and phosphofructokinase. RESULTS: After the resistance training program, there was a significant increase in 1 RM concentric squat strength for RT (35.9%) but not for CON (3.7%) (P < 0.05). However, there were no significant changes in OHT performance, LT, VO2, muscle fiber characteristics, or enzyme activities in either group (P > 0.05). CONCLUSION: The present data suggest that increased leg strength does not improve cycle endurance performance in endurance-trained, female cyclists. Eur J Appl Physiol. 2002 Dec;88(3):255-63.

Maximal strength-training with an emphasis on maximal mobilization during cross-country skiing increases exercise economy when double- poling. The aim of this experiment was to investigate whether the mechanism of this increase is a change in the force-velocity relationship and the mechanical power output. A group of 19 cross- country skiers having an average peak oxygen uptake of 255 ml x kg (-0.67) body mass x min(-1) or 61 ml x kg(-1) x min(-1) were randomly assigned to either a high resistance-training group (n=10) or a control group (n=9). Upper body endurance was tested on a ski ergometer. The high-resistance-training group trained for 15 min on three occasions a week for 9 weeks. Training consisted of three series of five repetitions using 85% of one repetition maximum (1RM), with emphasis on high velocity in the concentric part of the movement. Upper body exercise economy, 1RM and time to exhaustion increased significantly in the high resistance-training group, but was unchanged in the control group. Peak power and the velocities for a given load increased significantly, except for the two lowest loads. We conclude that the increased exercise economy after a period of upper body high resistance-training can be partly explained by a specific change in the force-velocity relationship and the mechanical power output. Scand J Med Sci Sports. 2002 Oct;12(5):288-95. The aim of this experiment was to examine the effects of maximal strength training with emphasis on neural adaptations on strength- and endurance-performance for endurance trained athletes. Nineteen male cross-country skiers about 19.7 +/- 4.0 years of age and a maximal oxygen uptake (VO(2 max)) of 69.4 +/- 2.2 mL x kg(-1) x min (-1) were randomly assigned to a training group (n = 9) or a control group (n = 10). Strength training was performed, three times a week for 8 weeks, using a cable pulley simulating the movements in double poling in cross-country skiing, and consisted of three sets of six repetitions at a workload of 85% of one repetition maximum emphasizing maximal mobilization of force in the concentric movement. One repetition maximum improved significantly from 40.3 +/- 4.5 to 44.3 +/- 4.9 kg. Time to peak force (TPF) was reduced by 50 and 60% on two different submaximal workloads. Endurance performance measured as time to exhaustion (TTE) on a double poling ski ergometer at maximum aerobic velocity, improved from 6.49 to 10.18 min; 20.5% over the control group. Work economy changed significantly from 1.02 +/- 0.14 to 0.74 +/- 0.10 mL x kg(-0.67) x min(-1). Maximal strength training with emphasis on neural adaptations improves strength, particularly rate of force development, and improves aerobic endurance performance by improved work economy.

In several recent studies, athletes experienced substantial gains in sprint and endurance performance when explosive training or high- intensity interval training was added in the noncompetitive phase of a season. Here we report the effect of combining these 2 types of training on performance in the competitive phase. We randomized 18 road cyclists to an experimental (n = 9) or control (n = 9) group for 4-5 weeks of training. The experimental group replaced part of their usual training with twelve 30-minute sessions consisting of 3 sets of explosive single-leg jumps (20 for each leg) alternating with 3 sets of high-resistance cycling sprints (5 x 30 seconds at 60-70 min(-1) with 30-second recoveries between repetitions). Performance measures, obtained over 2-3 days on a cycle ergometer before and after the intervention, were mean power in a 1- and 4-km time trial, peak power in an incremental test, and lactate-profile power and oxygen cost determined from 2 fixed submaximal workloads. The control group showed little mean change in performance. Power output sampled in the training sprints of the experimental group indicated a plateau in the training effect after 8-12 sessions. Relative to the control group, the mean changes (+/-90% confidence limits) in the experimental group were: 1-km power, 8.7% (+/-2.5%); 4-km power, 8.1% (+/-4.1%); peak power, 6.8% (+/-3.6); lactate-profile power, 3.7% (+/-4.8%); and oxygen cost, -3.0% (+/-2.6%). Individual responses to the training were apparent only for 4-km and lactate-profile power (standard deviations of 2.5% and 2.8%, respectively). The addition of explosive training and high-resistance interval training to the programs of already well-trained cyclists produces major gains in sprint and endurance performance, partly through improvements in exercise efficiency and anaerobic threshold.

To determine the effects of 12 wk of strength training on lactate threshold (LT) and endurance performance, 18 healthy untrained males between 25 and 34 yr of age were randomly assigned to either strength training (N = 10) or control (N = 8) groups. Despite no changes in treadmill VO2max or cycle peak VO2, a 33 +/- 5% increase (P less than 0.001) in cycling time to exhaustion at 75% of peak VO2 was observed following training. No significant changes in cycling time were observed in the control group. There were significant reductions in plasma lactate concentration at all relative exercise intensities ranging between 55 and 75% of peak VO2 training. The improved endurance performance was associated with a 12% increase in LT (r = 0.78, P less than 0.001). The strength training program resulted in significant improvements (P less than 0.001) of 31 +/- 5% and 35 +/- 7% in isokinetic peak torque values for leg extension and flexion, respectively, at a velocity of 30 degrees.s-1. There were also significant increases in 1-RM values of 30 +/- 4% (P less than 0.001) for leg extension, 52 +/- 6% (P less than 0.001) for leg flexion, and 20 +/- 4% (P less than 0.001) for the bench press. These findings indicate that strength training improves cycle endurance performance independently of changes in VO2max. This improved performance appears to be related to increases in LT and leg strength. J Appl Physiol. 1988 Nov;65(5):2285-90. Hickson RC, Dvorak BA, Gorostiaga EM, Kurowski TT, C. Department of Physical Education, University of Illinois, Chicago 60680. The impact of adding heavy-resistance training to increase leg-muscle strength was studied in eight cycling- and running-trained subjects who were already at a steady-state level of performance. Strength training was performed 3 days/wk for 10 wk, whereas endurance training remained constant during this phase. After 10 wk, leg strength was increased by an average of 30%, but thigh girth and biopsied vastus lateralis muscle fiber areas (fast and slow twitch) and citrate synthase activities were unchanged. Maximal O2 uptake (VO2max) was also unchanged by heavy-resistance training during cycling (55 ml.kg-1.min-1) and treadmill running (60 ml.kg-1.min-1); however, short-term endurance (4-8 min) was increased by 11 and 13% (P less than 0.05) during cycling and running, respectively. Long- term cycling to exhaustion at 80% VO2max increased from 71 to 85 min (P less than 0.05) after the addition of strength training, whereas long-term running (10 km times) results were inconclusive. These data do not demonstrate any negative performance effects of adding heavy- resistance training to ongoing endurance-training regimens. They indicate that certain types of endurance performance, particularly those requiring fast-twitch fiber recruitment, can be improved by strength-training supplementation.

Guest guest Posted January 12, 2007 Report Share Posted January 12, 2007 The following article may shed some light on the problems of mixing strength training and endurance training. Unfortunately when I saved the below article to my archives I failed to include the authors name an credentials. Ralph Giarnella MD Southington Ct, USA ********************************* Concurrent Resistance Training and Aerobic Training:?The Problem and the Science Behind the Solution The Problem Resistance training provides numerous and important health benefits through multiple mechanisms that may reduce the risks for diabetes, heart disease, possibly some cancers, and disabilities. There is much more extensive and long-standing evidence, however, about the benefits of aerobic training and cardiovascular fitness and disease risk reduction, particularly for reducing the risks of heart disease and for premature death from heart disease. What has always been tricky for people primarily interested in resistance training is how to incorporate aerobic training into an overall program without undermining strength development or hypertrophy (gaining muscle mass). The evidence shows that reaching some modest level of cardiorespiratory fitness can substantially reduce your risk of heart disease and early death even in the face of other prominent risk factors such as a family history of heart disease, high blood cholesterol, and high blood pressure1.'1 I've tried almost everything under the sun from long distance running to very brief, super high intensity interval training. There has never, however, been any combination ( " concurrent " ) of resistance training and aerobic training that seemed to optimally work. Whatever I devised and in whatever arrangement such as doing resistance training and aerobic training on the same or alternate days just didn't seem to work well over an extended time. Something was always not quite right and that even pertains to my more recent use of the brief, prescriptive Graded Exercise Protocol (GXP) for aerobic training described on this site. My problems - and perhaps yours - with concurrent training are not unique. It's an area that has been researched for many years. The Science Reviews of studies that have examined how aerobic training when combined in the same training program with resistance training can interfere with strength gains and hypertrophy (muscle mass) have pointed out that there is a great deal of inconsistency in this area of research. Sometimes strength gains and hypertrophy are blunted and sometimes they're not. The studies though are difficult to compare because across studies the aerobic and resistance training protocols have used different frequencies, intensities, and volume, training has been on the same day or alternate days, resistance training may or may not precede aerobic training, there may be different rest periods between resistance and aerobic training, and participants with different characteristics have been used. Theorists who have postulated such rationales for interference as acute or chronic fatigue, overtraining, or more basically, hormonal mechanisms, are not only left with an inconsistently done set of studies to try to fit into their theories, but they also need to explain why some studies showed interference and some did not. Docherty and Sporer have recently attempted in an extensive review article to advance the science by postulating specific physiological mechanisms affected by different training protocols that can predict when there will and will not be interference between aerobic and resistance training2. They then saw if their predictions fit some recent studies that have shown no or minimal interference. Throughout their article, the authors' insights and conclusions provide some important training guidelines. Docherty and Sporer noted that aerobic training to increase maximum oxygen consumption and hence the body's ability to transport and use oxygen is dependent upon both a central component involving adaptations in the cardiopulmonary system and a peripheral component involving adaptations in muscle tissues. Central and peripheral adaptations are, in turn, dependent upon different mechanisms. It does appear that the higher the intensity of the stimulus used to increase maximum oxygen consumption (e.g., high intensity interval training), the greater the increase in oxygen consumption. However, the location of the adaptation to aerobic training may shift depending upon the intensity of the stimulus. At lower levels of intensity, it appears that most of the adaptations occur centrally. With higher intensity training, more adaptations occur peripherally.' Docherty and Sporer noted that research suggests that training at between 70% to 80% of VO2max (70% to 80% of heart rate reserve; about 80% to 85% of maximum heart rate; just slightly below the anaerobic threshold) results in maximal contractile force in the heart and thus maximizes central adaptations important for health benefits. These findings are critical and suggest how concurrent training can be optimized. If you're using aerobic training to favorably influence your health through central adaptations, there may be no reason to train at levels that will result in more peripheral adaptations. The ability to perform at higher levels (e.g., run, bike, or swim very fast) does require training at high levels of intensity and specific peripheral adaptations, but such performance levels are not the goal of most people. I know that's not one of my goals. Aerobic training at very high intensities through its effects on mechanisms associated with peripheral adaptations may be the cause of blunting of strength gains and hypertrophy when aerobic training is done along with resistance training. Docherty and Sporer then discussed the mechanisms that appear involved in increasing strength and hypertrophy. The basic theory holds that high intensity aerobic training such as interval training affects specific mechanisms in peripheral adaptations such as those involved in increasing a muscle's oxidative capacity while a resistance training protocol for hypertrophy would try to increase protein synthesis and also stress the anaerobic energy system. The combination of the two training protocols is literally trying to force the muscles to adapt in very different ways. However, adaptations to steady state aerobic training below the anaerobic threshold may be primarily central and have little or no interference with strength or hypertrophy since different mechanisms are involved. The authors next reviewed several relatively recent studies where concurrent training was done in order to see if the interference model they developed was supported by the outcomes of these investigations. Although there was not a perfect fit to the model, it did appear that steady state training below the anaerobic threshold does not compromise strength gains. There are not yet enough data on hypertrophy to draw similar conclusions but this is likely to be the case. The Solution Strength athletes and bodybuilders may be great at high intensity interval training, but such training may be contraindicated if our goals involve maximizing strength and muscle mass while doing just enough aerobic training to protect our health and prevent disease It appears that training just below the anaerobic threshold, for example doing the several to five-minute work part in the Graded Exercise Protocol (GXP) at that level, is likely to provide health benefits associated with increased transport and use of oxygen through central adaptations and have minimal or no compromising effects on strength and hypertrophy. Thus, if your primary reasons for doing aerobic training revolve around health, there is a simple, efficient, relatively stress free way to do aerobic training that will allow you to still maximize strength and most likely, hypertrophy. So, given that I've been doing the GXP two to three times per week for over a year, what was I doing wrong that still created obvious interference with resistance training? It's really quite simple and once again exercise science had the answer. While really good endurance athletes can train just below their lactate threshold at 80% and even 85% of maximum oxygen consumption (VO2max; about 80% to 85% of heart rate reserve, and about 90% of HRmax), those of us not training for endurance events can not train at those levels and still be in relative steady state. As suggested by Docherty and Sporer and supported by research3, a top level for steady state training is likely to be about 75% of VO2max and heart rate reserve - the same level that optimizes central adaptations to the cardiopulmonary system. Even with the GXP I was still training at too high a level of intensity and experiencing interference (namely soreness form mechanical stress) with my resistance training. Using the heart rate reserve method, I now do a 5-minute graded warm-up to 70% of heart rate reserve, a five-minute steady state work segment at 75%, and then do a 5-minute cooldown that reverses the warm-up. You can easily experiment and find the appropriate level for your steady state work piece. It's a level that is challenging but one you could maintain for longer than the 5 minutes (perhaps 7 or 8 minutes or more) and where your heart rate is literally holding steady or only very slowing climbing upward. Using an old but still important heuristic, it's a level where you still can talk ( " the talk test " ). I've found that this slight alteration in my aerobic training is paying big dividends. I no longer experience any soreness or interference from aerobic training. It's also made aerobic training alot more flexible because I can do it almost anytime. I can do aerobic training after resistance training, or the next day, early in the day or late in the day. It doesn't seem to matter. I still make aerobic training challenging and interesting by having certain goals that I want to achieve over time for the 5-minute work part of the GXP that will indicate a good level of cardiovascular fitness. But, armed with information from exercise science I'll achieve this fitness goal without interfering with resistance training. References 1. P T.

It's important to remember that sprinting, jumping off the front, surging out of a crit corner, pursuit and kilo starts aren't " endurance activities " as that phrase is typically used--they're fueled by anaerobic metabolism, especially the PCr energy system. Regardless of whether it occurs at the end of a 100+ mile road race, sprinting on the bike isn't an endurance activity any more than sprinting 100m on the track. Although road cycling is commonly considered an " endurance sport, " it includes anaerobic efforts as well. But whether resistance training will help anaerobic efforts in cycling isn't the question you asked in your original post in this thread.

Bicycle racers have used the off season to maintain and improve physical fitness while off the bike during the winter months. Amongst the activities cyclists have participated in are Cyclocross, running, cross country skiing and resistance training. Once the bicycle training season begins in the spring those activities are put aside and all energy and effort are focused to on the bike training. I have taken to liberty to excerpt the chapter on strength training from the book <<The Lance Armstrong Performance Program- by Lance Armstrong and Chris Carmichael>> For any one not familiar with Lance Armstrong and cycling, Carmichael has been Lance's cycling coach since his early years in professional cycling. The bulk of the chapter discusses the various exercises and how to perform them- I have left those out- Lance's bench press routine is used to give an example of progression of the program over 3 months. ******************************* Chapter 10 Strength Training pgs. 100-112 “Strength training and cycling don’t mix when done concurrently. the best time to do strength training is during the late Autumn through winter- when most cyclists cut back on their riding because of weather.” “Lift lower weights at high repetitions, in the range of 15-20, if you want to increase endurance. Lift heavier weights at lower repetitions, in the range of 4-10 reps, if you want to increase strength.” Transition Phase: 2-4 weeks pushup, pull-ups and crunches Conditioning Phase: 4-6 weeks Light weights -high reps For example: Lance bench presses 100 lbs - `15-16 reps/ set 3 sets- Foundation Phase: 4-6 weeks Heavier weights with 10-12 reps 3 sets For example: Lance increases his weight to 110 lbs 10-12 reps 3-5 sets per workout Strength Phase: 4-6 weeks Increase weight and decrease reps For example- Lance bench presses 120 lbs at 8-10 reps with 5-7 sets per workout “For my first strength workout after the racing season is over, I sue the weight of the bar or machine for the sets and go through the full range of motion for each exercise. I’ve learned not to dive right back into strength training. Otherwise, my muscles are too sore the next day. By late winter, after I’ve been lifting steadily for 3 months, here’s what I can do. -8-10 reps 5-7 sets per workout Leg press: 400 lbs Hamstring curl: 80 lbs Leg extension: 120 lbs Biceps curl: 50 lbs Bench press 125 lbs. On The Bike Power Development phase As the get longer and the winter turns to spring its time to on-the-bike strength training. The Key to cycling success is to ride,ride.ride. (at this point Carmichael goes on to refer to a number of workouts on the bike which lead to increased biking strength.) ***************************************************** Ralph Giarnella MD Southington Ct, USA Quote Link to comment Share on other sites More sharing options...

His first sum is 9600 watt x minutes of total energy output or 576,000 joules of total work load. Also, what determines if this number or the 662,400 joules of his hyothetical second calcualtion is an " overload " ? In either case the athllete has not " produced wattage " during his summed intervals; wattage is the rate of work or energy production over a time periood ( a speed measurement of sorts and not a summative quantity). >>Notice the author misspells " Noakes " and doesn't provide any citation at all for his proposition that the trend observed by Dr. Noakes continues. It's also important to note the lack of logic here in attributing continuing increases in endurance performance to the discontinued short-term strength program instead of the long-term, continuing endurance training.<< Noticed and agreed! What produced the increased work output for certain was the application of increased energy to the input side of the cycle (pun intended ). Attribution of this increase to resistance training is hypothetical in the argument, not proved. >>Flame away.<< Hopefully not so much on this site as on others Best regards, Boardman, Chicago, US Quote Link to comment Share on other sites More sharing options...
Guest guest Posted January 14, 2007 Report Share Posted January 14, 2007 Ralph Giarnella MD submitted some of Lance Armstrong's coach's ( " Carmichael has been Lance's cycling coach since his early years in professional cycling. " )resistence training data from Lance's off season program. I would like to bring up some points: 1. As I have noted in prior posts, if you give 30 strength coaches a particular objective with the same athlete you're going to get 30 different training programs. Having said that I am frankly disappointed and suprised at the lack of sophistication in Carmichael's program. My program would call for all of Armstrong's off season, non-cycling training to be ground based, closed chain exercises. For example, I would never have Armstrong do leg extensions. Why? Because I follow the " philosophy that an exercise must utilyze 'Yes to the 4th power'. YES 1: Is the exercise ground based, and are you standing up while performing the exercise? YES 2: Is the exercise a free weight exercise? YES 3: Does the exercise work multiple muscle groups and surround multiple joints? YES 4: Is the exercise performend in an explosive manner? If my program design adheres to Yes to the 4th power at least 75% of the time then the program and exercises I select are good functional exercises. " - Mike Burgener's web site Herein further explication of why I'd use closed chain exercises in a passage from Chek: " The knee extension is performed such that the thigh is fixed to the machine,while the knee extension force generated by the quadriceps serves to move the tibia across the femur. In a squat, the trunk, hip and knee extensors act as prime movers, moving the femur across the tibia, which is the fixed distal segment (along with the foot) in this closed kinetic chain exercise. The relevance here lies in the fact that the motor recruitment patterns for the knee extension are 180 degrees out of phase with the recruitment patterns activated by the CNS to perform the squat. " This a major point which must " be considered when designing resistance training programs for athletes. If for example, you use an open chain leg press in attempt to develop explosive strength for sprinting, you will NEVER achieve optimal performance. To shed further light on this potentially " very deep subject " , when training a cyclist, you have carryover from both open chain and closed chain exercises due to the very nature of cycling (pushing the pedal down from a seated position vs. standing and driving a big gear or during an intense hill climb). " - Date: Mon, 16 Jun 1997 06:35:16 -0600 (MDT) Subject: (Weights-2) Open vs Closed chain exercise Link to Chek's full article: http://staff.washington.edu/griffin/kinetic_chain2.txt 2. For Chek, the " grey area " of open and closed chain exercises and how to use them to train cyclists is a big issue. It should be and it is only one of many issues consider in determining the efficacy of strength training for endurance athletes. Further, endurance cycling itself may be easily bifurcated into riders who are fast in the flats and strong hill climbers. So I am concerned that cycling may not be a good sport to use when trying to determine whether strength training is beneficial for endurance athletes. For that matter, what endurance sport lends itself to a simple analysis as to wether or not strength training improves performance? There is also the problem of specificity of training. For instance, are full range squats equally beneficial to runners and cyclist? In order to achieve some level of precision it seems that we are going to have to analyze each endurance event to determine what, if any strength training, is beneficial and if so, what training methods work best for each particular sport. An accurate, generalized conclusion seems rather unlikely. 3. We all know that endurance training and power development are on the opposite ends of the energy spectrum and therefor training for both conflicts. My solution for developing cardiopulmonary fitness without effecting power output in my power athletes is a combination of Concept ll Rowing Ergometer sprints and both track and hill sprints. The Erg training is for cardio and lactate threshold training, the sprints for increased VO2 max and cardiopulmonary training. The running sprints are never longer than 20 yds. That is to minimize strength and power loss while maintaining a very high level of cardiopulmonary fitness and muscular endurance. This training is very effective for wrestlers and volleyball players, among others. But wrestling and volleyball are not endurance sports. Not having trained any marathoners or triathletes I would like to know how strong they are. Perhaps some triathletes or runners and their coaches who have strength programs might report their experiences. At the very least, there is a changing perception of the ultra endurance athlete due to two men who are running extreme distances in very harsh conditions and neither sports the stereotypical marathoner's physique (skinny). One of them is Goggins, a Navy Seal who ran the 29th Annual Badwater 135-mile Ultramarathon and Dean Karnazes, who once ran 350 miles in 3 days and recently ran 50 marathons in 50 states in 50 days! Both of these incredible ultra endurance athletes are carrying some muscle mass in their upper bodies and legs. I have some familiarity with their nutritional programs (I wouldn't want thier grocery bill!), but have seen nothing in regard to their strength training or if they even do any strength training. Intuitively one would think some form of strength training would ultimately benefit any athlete, that it's just a matter of determining the correct exercises. It seems to me that we need to do a better job of defining our terms and then focus on individual endurance and specific stength training protocols in order to arrive at reasonable conclusions, if that's even possible without being forced to resorting to western reductionist style research. Surely we have enough experiential and anecdotal data amongst us that we may arrive at substantial conclusions and possibly recommendations for enhancing the performance of a variety of endurance athletes through strength training.

Guest guest Posted January 15, 2007 Report Share Posted January 15, 2007 My recollection is that most of the studies that have found weight training beneficial have been studies involving endurance runners or skiers and most of the studies that found little if any benefit have involved endurance cyclists or swimmers. Since neither swimmers nor cyclists deal with gravity and ground forces the way runners and skiers do, this suggests that traditional weight training may not be the best way to go for them. Also, I don't believe there are any studies finding weight training beneficial at distances of more than 5K. That is not to say that weight training is not beneficial for 10K or marathon runners, it is just that I don't believe it has been studied. We may need to be more specific in terms of what we mean when we say " endurance " both in terms of the activity (running, swimming, skiing or cycling) and the time spent, 15 minutes, 30 minutes, 2 hours, or several days, when discussing the benefits (or lack thereof) of weight training. As far as I know, all of the studies that have found " interference " in concurrent training (weights plus aerobic endurance) have found that it was strength gains that were compromised, not aerobic gains. It should be noted that this only means that strength gains were slower among concurrent trainers than among those just lifting weights, not that there were no strength gains among the concurrent group. Since there seems to be general agreement by Dr. Stone and the folks at Ball State that there can be a substantial delay between the body's ability to gain strength and its ability to coordinate that strength into sporting movements to yield performance improvements, there seems to be little justification for endurance athletes in devoting any long block of time to just strength improvement. The example of Lance Armstrong's strength training is the classic periodized high volume light to heavier weight training. It is probably useful as a means of general strengthening and injury prevention, but does not appear to be specifically designed to improve performance. It also a very long workout. Interestingly, despite the body building 8-10 rep 5-7 set protocol it apparently produced little hypertrophy. This is probably because of the both the make up of the individual and the continued riding. Skinny endurance athletes worrying that they may gain mass from lifting weights should take a lot of comfort in Armstrong's workout. It seems to me that if you are going to use weight training beyond a few weeks of general conditioning, you should use it for the one thing it does better than any other form of exercise, improve strength. Strength endurance should come from the activity itself with perhaps some modifications (e.g., hills). You should limit the time you devote to weight training since it is a supplemental form of training. When we talk about flexibility training, we generally mean a few minutes of passive or active stretching before or after a workout. We don't mean 1 hour of yoga poses a day on top of running or cycling. Yet when we talk about supplemental weight training, the assumption generally is that it is going to take an hour or more a day out of what little available time the endurance athlete has. An endurance athlete who does 3 sets of 2-3 reps of squat or deadlift will spend perhaps 10 seconds per rep lifting or 30 seconds each set for a total of 90 seconds. The recommended recovery periods are generally 3-5 minutes between sets for weights in the 2-3 rep range. If he takes the full 5 minutes, he will have spent 10 minutes resting and 90 seconds lifting. Add in a few minutes warming up and his weight training could be as little as 15 minutes a day. If he lifts 3 times a week, he will spend a little more than 3 hours a month on weight lifting. Yet in most cases he will significantly improve his strength and will be far less likely to gain mass than under the Armstrong protocol. He won't have the strength or speed of a a sprinter so he won't be able to produce the high power outputs of a sprinter, but he will be a stronger, more powerful endurance runner which has been shown, at least up to 5K, to improve performance.

Guest guest Posted January 15, 2007 Report Share Posted January 15, 2007 A cyclist's feet aren't literally on the ground. They are seperated from the ground by the bike, through which they must generate power to the ground by pushing the pedals. For all training not actually using the bike I would stay with closed chain exercises. As a former cyclist myself 35 yrs ago putting in 40-50 miles daily and over 500 miles in three days, twice monthly, I ran sprints, stairs and did full range squats with my soccer coach to increase my speed on the flats. It seemed to help, but I can't say definitively because I was also doing sprints on the bike during the weekends I wasn't riding from Goleta, Ca to San Diego, Ca. and back. Since then I haven't yet seen any reason to abandon closed kinetic chain training for strength and power development, for the reasons stated in my post, adhereing to the concept of Yes to the 4th power. There are several subtle benefits to closed chain exercises and adhereing to Yes type training. For a cyclist one of the more important would be the additional isometric strenghtening of the core. A stronger core means less of the cyclist's energy is dissipated through the body, so more power is genertaed with each stroke, for example. Hope this answers your question. I'd be interested in hearing other positions on this tangent fron the strength training for endurance athlete's conundrum. W.G.

Skip Dallen Covina, CA (Weights-2) Open vs Closed chain exercise Link to Chek's full article: http://staff.washington.edu/griffin/kinetic_chain2.txt 2. For Chek, the " grey area " of open and closed chain exercises and how to use them to train cyclists is a big issue. It should be and it is only one of many issues consider in determining the efficacy of strength training for endurance athletes. Further, endurance cycling itself may be easily bifurcated into riders who are fast in the flats and strong hill climbers. So I am concerned that cycling may not be a good sport to use when trying to determine whether strength training is beneficial for endurance athletes. For that matter, what endurance sport lends itself to a simple analysis as to wether or not strength training improves performance? There is also the problem of specificity of training. For instance, are full range squats equally beneficial to runners and cyclist? In order to achieve some level of precision it seems that we are going to have to analyze each endurance event to determine what, if any strength training, is beneficial and if so, what training methods work best for each particular sport. An accurate, generalized conclusion seems rather unlikely. 3. We all know that endurance training and power development are on the opposite ends of the energy spectrum and therefor training for both conflicts. My solution for developing cardiopulmonary fitness without effecting power output in my power athletes is a combination of Concept ll Rowing Ergometer sprints and both track and hill sprints. The Erg training is for cardio and lactate threshold training, the sprints for increased VO2 max and cardiopulmonary training. The running sprints are never longer than 20 yds. That is to minimize strength and power loss while maintaining a very high level of cardiopulmonary fitness and muscular endurance. This training is very effective for wrestlers and volleyball players, among others. But wrestling and volleyball are not endurance sports. Not having trained any marathoners or triathletes I would like to know how strong they are. Perhaps some triathletes or runners and their coaches who have strength programs might report their experiences. At the very least, there is a changing perception of the ultra endurance athlete due to two men who are running extreme distances in very harsh conditions and neither sports the stereotypical marathoner's physique (skinny). One of them is Goggins, a Navy Seal who ran the 29th Annual Badwater 135-mile Ultramarathon and Dean Karnazes, who once ran 350 miles in 3 days and recently ran 50 marathons in 50 states in 50 days! Both of these incredible ultra endurance athletes are carrying some muscle mass in their upper bodies and legs. I have some familiarity with their nutritional programs (I wouldn't want thier grocery bill!), but have seen nothing in regard to their strength training or if they even do any strength training. Intuitively one would think some form of strength training would ultimately benefit any athlete, that it's just a matter of determining the correct exercises. It seems to me that we need to do a better job of defining our terms and then focus on individual endurance and specific stength training protocols in order to arrive at reasonable conclusions, if that's even possible without being forced to resorting to western reductionist style research. Surely we have enough experiential and anecdotal data amongst us that we may arrive at substantial conclusions and possibly recommendations for enhancing the performance of a variety of endurance athletes through strength training.>>> Quote Link to comment Share on other sites More sharing options...
Guest guest Posted January 16, 2007 Report Share Posted January 16, 2007 Point is that the goal should not be to improve maximum force, but maximum power or even optimum power. Also, as for any training, different physical qualities need to be developed. Fact is, that since the cardio-vascular and aerobic doctrine entered the training and medical practice (and science) the focus on improving power has been lacking. A good example is long distance running, where the africans train much more on power, while white europeans have focussed a long time on over distance training. Now I notice that many researchers - at least in constructing their program - do not know how to bring more accent to improving power and not force, i.e. focus more on weight than on velocity/impulse. The key is, to focus on the individual needs and bring in the right mix of training goals. drs Huizing Enschede, The Netherlands ================ Re: Maximum Strength and Endurance Performance? Cowell wrote: > Any thoughts? Well, my first thought is, " here we go again. " This topic has been debated here several times before. The people who participate on this forum tend to be much more knowledgeable in strength training than endurance training, so it seems to be no coincidence that the folks here are pretty sympathetic to the idea that increasing strength will increase endurance performance. However, if you go to the google group on wattage (a cycling discussion group) and raise this topic, you'll find that this idea enjoys much less acceptance among the people there who have studied endurance performance. That said, here are some thoughts. The following qotations are from the article at http://www.titanspo rtsperformance. com/missinglink. html > However as a cycling coach and strength and conditioning coach > the goal in training the endurance athlete is producing greater > amounts of sustainable power.

Okay, but why would non-specific exercise such as strength training be more effective at doing this than the specific endurance task itself? After years of participating in these debates, I have yet to hear a scientific explanation for this. This article is a perfect example of a person repeatedly making the assertion that strength training improves endurance performance without offering any support for it. > For example, > if during a long duration tempo ride (65-75% of VO2 max) the athlete > is able to produce a greater amount of average power without > exceeding the prescribed intensity the athlete will receives a > greater overload during the same duration of time. Well, that gets it exactly backwards. If the athlete is able to produce a greater power output (relative to previous performances) at the same percentage of VO2max, then the athlete has *demonstrated* a performance increase. However, if the athlete used to be able to maintain, e.g., 240 watts at 70% VO2max for three hours and is now able to maintain, e.g., 250 watts at 70% VO2max for three hours, then a three hour ride at 250 watts is not an " overload " at all--it's still a three hour ride at 70% of VO2 max. It is merely maintaining the new status quo. It's also worth mentioning that 60-70% of VO2max isn't a " tempo " workout at all, and that we really should be looking at a percentage of VO2 at lactate threshhold or OBLA, and not a percentage of VO2max. I mention these ideas only briefly to show that the author of this article doesn't really know what he's talking about. > Properly managed resistance > training provides the athlete the ability to generate higher levels > of sustainable power throughout sport specific training sessions.

Very vague, but if we assume he means that the use of resistance training can increase power production in endurance sports, then he's once again making this assertion without offering any support for it. > In many cases the exercise protocol prescribe for endurance athletes > leans more toward hypertrophy which will in the short run produce > lower performance in most endurance training programs.

Exactly. Notice how the author never explains how to design a resistance training program that gets around this problem. > Most endurance sport > performance is driven by the ability to sustain maximum power....

Yes, like maybe the athlete should be training to increase power at LT/OBLA instead of power at and above VO2max. Again, how would strength training increase power at LT/OBLA?

Notice the author misspells " Noakes " and doesn't provide any citation at all for his proposition that the trend observed by Dr. Noakes continues. It's also important to note the lack of logic here in attributing continuing increases in endurance performance to the discontinued short-term strength program instead of the long-term, continuing endurance training. > SUMMARY: > > 1) Research shows that resistance training aids endurance athletes.

The area under a force velocity graph represents the power generated in doing this work. One can increase one's power generation by increasing the force applied during the action or increasing the velocity of the action (shorten the time base for accomplishent or increase the displacement over the time base). If one wishes to be " improving power and not force " ; then one can only improve velocity during the action; no other choices exist. BTW; weight is just a force and impulse is a force applied for a length of time resulting in a momentum change in free body applications. Impulse is the mathematical product of the force applied and time duration of the application. Science and its application to training are not served by incorrect usage of very specific physical terminology. Only confusion and misunderstanding can result. These Newtonian concepts are over three centuries old and not subject to personal interpretation or opinion. They are invariant in the matters under discussion.

Guest guest Posted January 16, 2007 Report Share Posted January 16, 2007 The bottom line is that hypertrophy decreases mitochondria density which is contra to what endurance athletes want. Typically weight training results in hypertrophy. Weight training can be very beneficial for cyclists when applied to the non-prime movers and it does help in injury prevention for cyclists. However, aside from track sprinters (cyclists not runners), weight training from the hips down is of little/no value FOR MAKING ONE FASTER ON THE BIKE and the science bears that out.

With regards to focusing on improving power, at least in cycling, there has been a significant change in the focus of training. The availability of power meters as a practical training tool has change not only the way that elite cyclists train, but even the amateur cyclists as well. Rowing enthusiasts also have access to power meters which are an integral part of the Concept II rower and has been for several years. To that point I will re-post an excerpt from Lim Phd - Powerfeed Analyst- and coach of Floyd Landis. ***************************************** Some Thoughts on Peak Power: Because, I'm often referring to Floyd's peak power data, I'd thought I'd take a little bit of time and officially introduce this very important variable. I'll start by saying that everyone is always asking me what Floyd's maximum power is. As if, he's some sort of racecar and they want a horsepower rating before they haggle with the salesman. The reality is, there is no such thing as a single maximum power output value for a cyclist. Rather, there are different maximum or peak power values for different time frames. So instead of saying that Floyd's max power is an arbitrary 475 watts, I can say for 5 minutes the highest we've ever seen him hold is 475 watts. That's also why we use the term " peak " instead of " max. " When we say " peak, " it's a subtle distinction that means the value is the highest we've ever measured to date. When we say, " max " there's the understanding that the value is the highest that has ever and will ever be measured. Since Floyd is still improving, we stick with peak. When he retires, we'll tell you what his max was. In any case, just like runners can have personal bests or PR's for different distances (the mile, a 10 km run, or a marathon), a cyclist can have personal bests or peaks for different time frames. We measure those bests as the highest wattage a cyclist can for a distinct time period. In our case, we measure the highest power Floyd holds each day for 5 seconds, 30 seconds, 1 minute, 5 minutes, 30 minutes, 1 hour, and 2 hours. The reason why we chose these different time frames is because performing all out for each requires a distinct combination of physiological attributes. As an example, going all out for 5 seconds is really dependent on anaerobic energy sources (i.e., energy production without the use of oxygen), whereas going all out for 2 hours is completely dependent on aerobic energy sources (i.e., energy production exclusively through the use of oxygen). In addition, an all out effort for 5 minutes is very close to an athlete's maximal aerobic capacity or VO2 max. An all out effort for 30 minutes to 1 hour is very close to an athlete's lactate threshold. Since, these different time frames place distinct physiological demands on the body, cyclists who are better at sprinting tend to have better peak power outputs in the 5 second to 1 minute time frame, while cyclists who are better at time trialing or climbing normally have better peak power outputs for the 5 minute to 2 hour time frame. A sprinter here at the Tour might be able to hold 1700 or more watts for 5 seconds while Floyd probably won't crack 1000 watts. On the other hand, Floyd will probably be able to hold over 400 watts for 30 minutes, while a sprinter of equal weight will be lucky to hold over 350 watts. Regardless of the type of cyclist, however, there is an exponential or cubic like relationship between a given time frame and the power that can be held. In other words, there's a real fast and steep drop in peak power output between 5 seconds and 1 minute, and a smaller drop between 5 minutes and 30 minutes, and a shallow drop between 1 hour and 2 or more hours. ******************************************************* There are some very important points that Dr. Lim has made in the above excerpt that should be evaluated when thinking in terms of strength training an endurance training. The most important concept to keep in mind is the statement: << " these different time frames place distinct physiological demands on the body, " >> All too often when training we think in terms of how much can an individual lift or how fast can they cycle or run. We then conclude that if they can lift more or cycle or run faster then they are more powerful. We fail to add in the time frame of the accomplishment. A person who runs fastest at 100 meters probably will not be faster than someone who runs a fast marathon. The reason is different training brings about different physiological adaptations. Which runner is more powerful? It all depends on your time frame, since power implies a time frame. The sprinter is more powerful over a 10-15 sec time frame but the marathoner is more powerful over the 2-3 hour time frame. Maximum strength implies maximum 1 rm. Maximum 1 rep lift requires totally different physiological development than performing the same motion 10,000 times. (a cyclist pedaling at 90 rpm x 120 minutes = 10,800 reps (my calculations) ) - << " To run a marathon in two hours and eight minutes, for example, a runner's leg muscles need to develop the capacity to take about 23,000 rapid but submaximal steps without stopping ('submaximal steps' means strides taken with fairly moderate force production) Owen - Peak Performance On Line,>> It should be obvious from the above two examples that the physiological needs of high endurance athletes are totally different than the physiological needs of an athlete whose activity lasts less than 1 minute. The following excerpt from the above quotation from Dr. Lim is very important in illustrating this point. <<A sprinter here at the Tour might be able to hold 1700 or more watts for 5 seconds while Floyd probably won't crack 1000 watts. On the other hand, Floyd will probably be able to hold over 400 watts for 30 minutes, while a sprinter of equal weight will be lucky to hold over 350 watts. >> In short there is no correlation between maximum peak power over 5 seconds and maximum peak power for 30 minutes. Increasing maximum strength does not necessarily result in greater endurance performance. This is particularly true amongst the elite athletes. Is there a role for resistance training for the endurance athlete? Lance Armstrong's off season workout shows that in fact there is a place for this. As a change of pace during the months between racing seasons the endurance cyclists will be involved in multiple activities including weight lifting, cross country skiing, mountain biking, running and swimming. These activities are done to prevent loss of fitness, weight gain, and to strengthen of the inherent weakness which come about from performing one type of exercise to the exclusion of others. In the not too distant past many elite cyclists would spend several months just doing nothing and spend the spring session trying to get back into shape. Jan Ullrich- perennial runner up to Lance is a perfect example of a cyclist who did very little in the off season and generally started the cycling season with as much as a 20 lb weight gain. We could cover the different physiological changes brought about by resistance training vs endurance training but much of that has been covered in previous posts over the past several years.
