Whole-body-vibration–induced increase in leg muscle activity during different squat exercises. J. Strength Cond. Res. 20(1):124–129. 2006.—This study analyzed leg muscle activity during whole-body vibration (WBV) training. Subjects performed standard unloaded isometric exercises on a vibrating platform (Power Plate): high squat (HS), low squat (LS), and 1-legged squat (OL). Muscle activity of the rectus femoris, vastus lateralis, vastus medialis, and gastrocnemius was recorded in 15 men (age 21.2 ± 0.8 years) through use of surface electromyography (EMG). The exercises were performed in 2 conditions: with WBV and without (control [CO]) a vibratory stimulus of 35 Hz. Muscle activation during WBV was compared with CO and with muscle activation during isolated maximal voluntary contractions (MVCs). Whole-body vibration resulted in a significantly higher (p < 0.05) EMG root-mean-square compared with CO in all muscle groups and all exercises (between +39.9 ± 17.5% and +360.6 ± 57.5%). The increase in muscle activity caused by WBV was significantly higher (p < 0.05) in OL compared with HS and LS. In conclusion, WBV resulted in an increased activation of the leg muscles. During WBV, leg muscle activity varied between 12.6 and 82.4% of MVC values. -------------------------------------------------------------------- Int J Sports Med. 2005 Oct;26(8):662-8.

ABSTRACT Despite the expanding use of Whole Body Vibration training among athletes, it is not known whether adding Whole Body Vibration training to the conventional training of sprint-trained athletes will improve speed-strength performance. Twenty experienced sprint-trained athletes (13 male symbol, 7 female symbol, 17-30 years old) were randomly assigned to a Whole Body Vibration group (n=10: 6 male symbol and 4 female symbol) or a Control group (n=10: 7 male symbol, 3 female symbol). During a 5-week experimental period all subjects continued their conventional training program, but the subjects of the Whole Body Vibration group additionally performed three times weekly a Whole Body Vibration training prior to their conventional training program. The Whole Body Vibration program consisted of unloaded static and dynamic leg exercises on a vibration platform (35-40 Hz, 1.7-2.5 mm, Power Plate). Pre and post isometric and dynamic (100 degrees/s) knee-extensor and -flexor strength and knee-extension velocity at fixed resistances were measured by means of a motor-driven dynamometer (Rev 9000, Technogym). Vertical jump performance was measured by means of a contact mat. Force-time characteristics of the start action were assessed using a load cell mounted on each starting block. Sprint running velocity was recorded by means of a laser system. Isometric and dynamic knee-extensor and knee-flexor strength were unaffected (p>0.05) in the Whole Body Vibration group and the Control group. As well, knee-extension velocity remained unchanged (p>0.05). The duration of the start action, the resulting start velocity, start acceleration, and sprint running velocity did not change (>0.05) in either group. In conclusion, this specific Whole Body Vibration protocol of 5 weeks had no surplus value upon the conventional training program to improve speed-strength performance in sprint-trained athletes. -------------------------------------------------------------------- Int J Sports Med. 2004 Jan;25(1):1-5.

Exercise Physiology and Biomechanics Laboratory, Faculty of Physical Education and Physiotherapy, Department of Kinesiology, Katholieke Universiteit Leuven, Tervuursevest 101, 3001 Leuven, Belgium. ABSTRACT The aim of this study was to investigate and to compare the effect of 24 weeks " whole body vibration " training and fitness training on body composition and on muscle strength. Forty-eight untrained females (21.3 +/- 2.0 yr) participated in the study. The whole body vibration group (N = 18) performed unloaded static and dynamic exercises on a vibration platform (35 - 40 Hz, 2.5 - 5.0 mm; Power Plate). The fitness group (N = 18) followed a standard cardiovascular (15 - 40 min) and resistance training program including dynamic leg press and leg extension exercises (20 - 8 RM). Both groups trained 3 times weekly. The control group (N = 12) did not participate in any training. Body composition was determined by means of underwater weighing. Additionally 12 skinfolds were assessed. Isometric (0 degrees /s) and isokinetic (50 degrees /s, 100 degrees /s, 150 degrees /s) knee-extensor strength was measured by means of a motor-driven dynamometer (Technogym). Over 24 weeks there were no significant changes (p > 0.05) in weight, in percentage body fat, nor in skinfold thickness in any of the groups. Fat free mass increased significantly in the whole body vibration group (+ 2.2 %) only. A significant strength gain was recorded in the whole body vibration group (24.4 +/- 5.1 %; 5.9 +/- 2.1 %; 8.3 +/- 4.4 %; 7.6 +/- 1.5 %) and in the fitness group (16.5 +/- 1.7 %; 12.0 +/- 2.7 %; 10.4 +/- 2.3 %; 10.2 +/- 1.9 %), at 0 degrees /s, 50 degrees /s, 100 degrees /s and 150 degrees /s respectively. In conclusion, 24 weeks whole body vibration training did not reduce weight, total body fat or subcutaneous fat in previously untrained females. However, whole body vibration training induces a gain in knee-extensor strength combined with a small increase in fat free mass. The gain in strength is comparable to the strength increase following a standard fitness training program consisting of cardiovascular and resistance training. --------------------------------------------------------------------- Rittweger, Beller, Felsenberg (2000) Acute physiological effects of exhaustive whole-body vibration exercise in man. Clinical Physiology 20 (2), 134–142. ABSTRACT Vibration exercise (VE) is a new neuromuscular training method which is applied in athletes as well as in prevention and therapy of osteoporosis. The present study explored the physiological mechanisms of fatigue by VE in 37 young healthy subjects. Exercise and cardiovascular data were compared to progressive bicycle ergometry until exhaustion. VE was performed in two sessions, with a 26 Hz vibration on a ground plate, in combination with squatting plus additional load (40% of body weight). After VE, subjectively perceived exertion on Borg's scale was 18, and thus as high as after bicycle ergometry. Heart rate after VE increased to 128 min-1, blood pressure to 132/52 mmHg, and lactate to 3.5 mM. Oxygen uptake in VE was 48.8% of VO2max in bicycle ergometry. After VE, voluntary force in knee extension was reduced by 9.2%, jump height by 9.1%, and the decrease of EMG median frequency during maximal voluntary contraction was attenuated. The reproducibility in the two VE sessions was quite good: for heart rate, oxygen uptake and reduction in jump height, correlation coefficients of values from session 1 and from session 2 were between 0.67 and 0.7. Thus, VE can be well controlled in terms of these parameters. Surprisingly, an itching erythema was found in about half of the individuals, and an increase in cutaneous blood flow. It follows that exhaustive whole-body VE elicits a mild cardiovascular exertion, and that neural as well as muscular mechanisms of fatigue may play a role. --------------------------------------------------------------------- A friend of mine also read a study where I believe they looked at the effect of high jumping. Two groups, one using vibration plate training (i.e. the power plate) the other group not using it. Both groups were on the same strength program. The results found that there were no significant changes between groups. I've also personally used one and recommend not going on it if you have a head ache.

Guest guest Posted March 21, 2007 Report Share Posted March 21, 2007 Owen addresses the issue of vibration training in his March issue of Running Research News. He analyzes the current research and draws the following conclusions: " Jumping aboard vibrating hustings does activate alpha motoneurons and leg muscles, and such activation during exercise seems to lead to some special improvements in muscle strength in untrained individuals. WBV also activates the alpha motor neurons and muscles of well-trained athletes, but – hey! – those nerve cells and sinews have already been charged up by rigorous training. The relatively modest degree of muscle and reflex activation induced by WBV and the resulting neuromuscular adaptations appear to be swamped by the effects of very challenging workouts, even – believe it or not! – when those sessions are unimaginatively conducted on non-vibrating ground. Muscular strength and power, motornerve- cell excitability, fast-twitch-fiber recruitment, and reflex sensitivity and reaction time are all very nicely developed in well-trained runners, and it is doubtful that “shaking up the legs†with vibrations will produce any additional adaptations " Ken Jakalski Lisle High School Lisle, IL Quote Link to comment Share on other sites More sharing options...

The relatively modest degree of muscle and reflex activation induced by WBV and the resulting neuromuscular adaptations appear to be swamped by the effects of very challenging workouts, even – believe it or not! – when those sessions are unimaginatively conducted on non-vibrating ground. Muscular strength and power, motornerve- cell excitability, fast-twitch- fiber recruitment, and reflex sensitivity and reaction time are all very nicely developed in well-trained runners, and it is doubtful that “shaking up the legs” with vibrations will produce any additional adaptations " Ken Jakalski Lisle High School Lisle, IL Quote Link to comment Share on other sites More sharing options...

" (Galileo Galilei) > *** Here are extracts from an interview with Henk Kraaijenhof (ST member): " " Henk Kraaijenhof has been coaching elite athletes since 1978. As well as being the personal coach of Nelli Cooman and Merlene Ottey he has worked as a conditioning consultant for many professional athletes from other sports, the Police and Special Forces. So you have worked with a lot of new technology over the years? How best can technology help coaches? It is very simple, we cannot do without technology. How can we today live without a mobile phone, without a computer, without electronic timing. Of course you can still measure time with an hourglass but it won't be of much use. Of course you can do jump and reach tests by wetting your fingers and using a wall. When you use a phone you don't have to call an operator and mess around with all the wires so why would you do it in track and field? Since we are looking for the small advantage we should make use of technology as much as it is useful. We are not looking at toys for boys but tools for coaches and remember that the most powerful tools don't turn a coach into superman they are only as useful as the coach allows them to be. You can put the best brush in my hand but I won't paint a Van Gogh or a Rembrandt. Which of these systems was the most useful to you? They all had their place and they all took care of improving performance but if I got one tenth of a second off the 100m but using the vibration platform (a system developed by Italian sports scientist Camillo Bosco which can improve vertical jump without stressing the tendons or bones) or one tenth using the OmegaWave (a system developed by Russian sports scientists who defected to the US, which allows the coach to look inside the body and actually see supercompensation occurring in each of the body systems separately) or one tenth of a second using the Speedy System (a cheap and easy method of performing assisted and resisted running) then they were always useful. It is hard to say what contributed more to performance because I often used simple tools to make the biggest improvement at the beginning but as the athletes got closer and closer to the top of the world, I had to be more precise in my evaluation. You don't need any tools to get an athlete from 12 flat to 11 but you may need them to get from 10.3 to 10 flat. So many things were useful. The vibration platforms and the Bosco concept, which includes using Muscle Lab (a system for measuring power and jumping ability), to study and measure neuromuscular properties and how they changed and varied with training were extremely useful. The Speedy system, a very cheap and easy to use piece of kit, which I wrote about in the 1980s, also helped me a lot. More recently it has mainly been OmegaWave and other more complex stuff that allows us to study what is going on inside the body – and how the mind and body are connected and affect performance.

Guest guest Posted March 25, 2007 Report Share Posted March 25, 2007 Good or bad vibrations?? Read about the true nature of the vibration equipment business, just a tip of the iceberg of unfulfilled promises, untruthful marketing, (=straight lies), fake protocols and machines that don't work at all...more to come ... Exerpts from an article that appeared in all major Dutch newspapers this week: (underscore is mine) A couple claimed the sum of 21 million Euro against Power Plate International in Badhoevedorp (Holland), distributor of vibration equipment for weightloss. The court in Haarlem already allocated the sum of 900.000 Euro payment in advance to the couple. Frans Giezen en Nelke van Aspert signed a contract with PPI in 2004 in which the company of the couple became distributor for the Middle-East. In the beginning of 2006 PPI was taken over by an US investor, while founder Guus van der Meer stayed President of the Board of Directors. The new investors proposed a new contract to the couple, but they refused to sign it because it contained different conditions. PPI dissolved the contract unilaterally. The couple now requests action on the merits for loss of income. In an earlier stage the couple, already asked for seizure of the possessions of van der Meer. His request for upheaval of the seizure was denied by the judge. Excerpt: (Dutch) Een echtpaar heeft een claim van 21 miljoen euro ingediend tegen Power Plate International uit Badhoevedorp, leverancier van de trilapparaten waarmee mensen kunnen afvallen. De rechtbank Haarlem heeft in kort geding al een voorschot van 900.000 euro aan het echtpaar toegewezen. Frans Giezen en zijn echtgenote Nelke van Aspert hebben in 2004 met PPI een contract gesloten waarbij het bedrijf van het echtpaar de distributie in het Midden-Oosten zijn rekening nam. Begin 2006 werd PPI overgenomen door een Amerikaanse investeerder. Oprichter Guus van der Meer bleef aan als bestuursvoorzitter. De Amerikanen legden de distributeurs een nieuw contract voor. Giezen en Van Aspert weigerden dit te ondertekenen, omdat het zwaardere voorwaarden bevatte, waarna PPI het contract eenzijdig ontbond. Het echtpaar vordert nu in een bodemprocedure, die volgende week begint, 21 miljoen euro als compensatie voor gederfde winst. Giezen en Van Aspert hebben eerder al beslag laten leggen op bezittingen van Van der Meer. Zijn verzoek om dit beslag op te heffen, is door de rechter afgewezen.
