Guest guest Posted January 15, 2004 Report Share Posted January 15, 2004 << I have seen Mike boyle teach drawing in and the NASM teaches drawing in. Are the versions taught by these two different from what is taught by CHEK? Would you recommend doing a drawing in routine alond with the traditional abdominal workout? >> NASM and Mike seem to be " one entity " on this matter, while Boyle and Check are seemingly cut from the same cloth as . Over a year and a half past, I wrote a letter to Supertraining describing my personal experience with this mania here in the Chicago area where a popular and highly respected trainer is training hockey players and others to consciously " draw - in " prior to execution of almost any remotely athletic maneuver; thereby distracting the athlete from the task at hand and discouraging the automatic and natural response of the abdominals in the kinetic chain to imposed demand during training or competition. I would reference that letter if I only knew how to find it myself in the (yahoo?) Supertraining files. Perhaps the moderator could reference it for me? I include a reprint at the bottom of this letter. The trainer referred me to a medical research journal article that had referenced and it proved upon examination to be unrelated to the question. This trainer still persists, even so, with his insistence on belly button sucking for core stabilization! Just recently another trainer (CSCS certification) was published in the latest issue of the NSCA journal with yet again the same advice despite research published previously in this journal demonstrating that the " draw-in " technique has a training effect intensity only on the external obliques and not on the TVA; and I have met USAW coaches (who should certainly know better!) parroting Chek and Boyle and /NASM. No wonder certifications and authority are subject to so much question and even scorn by the layman and the professional alike! Regarding the espousal of this modern myth extracted whole cloth from rehab and misapplied to athletic training, we may always have its " teaching " amongst us and especially so as long as it is lucrative for its promoters. Boardman Chicago ****copy of original letter concering Spine journal article purportedly proving Mike 's contention regarding core stabilization*** Recently, a local trainer (ATC) published the statement; " I do suggest to perform the draw in maneuver to activate the core. Research has shown that the spine is not stable until this maneuver is performed. " When I contacted him and asked for the research reference, he invoked the authority and writings of Mike and Mike Boyle. I said that I was aware of their " opinions " but was looking for the research that supported such opinions. He then referred me to a Journal article that he claimed had been referenced by Mr. . It is: " Stability Increase of the Lumbar Spine With Different Muscle Groups. A Biomechanical In Vitro Study. " SPINE Volume 20, Number 2, pp. 192-198, 1995, J. B. Lippincott Company. A red flag began to rise in my mind when he said " In Vitro " and I asked the trainer if he had read the journal research article? He admitted that he had not actually read it himself. I thanked him for the reference and began to look for it on line. It was not available online or through the interlibrary loan system, but I was able to procure it through the good offices of the local librarian and the medical school library at U of I. This journal is evidently quite pricey and therefor not well circulated. Obtaining the article took a couple weeks waiting time but when it finally arrived it confirmed my suspicions. The research had nothing whatever to do with " the draw in maneuver " (activating the TVA)! It didn't begin to relate to athletic performance in human beings! The article dealt with simulating muscular tension on isolated sections of the test spines of cadavers for purposes of better evaluating new surgical and therapeutic techniques regarding implanted devices for spinal fixation. Even then, a reviewers' comment (Tom Bendix of Copenhagen, Denmark) at the end of the journal piece remarked, " Is there any indication from the literature that the forces investigated are within the limits of relevant physiologic forces? " So.........next time you wonder how this stuff gets its seeming credibility and currency in the training universe, recall this little anecdote. It is much easier to accept the claims of the popular and successful purveyors of " opinions " and training systems than to investigate the claims and think for ones' self. Besides.......nationally known trainers wouldn't knowingly mislead us with references to difficult to obtain research literature, would they? I intend to contact the trainer in question and offer him the article for educational purposes and to inform him that it in no way supports the " maneuver " that has become the gold standard for core activation cultism. Over to you, Boardman Chicago Il. Quote Link to comment Share on other sites More sharing options...

Guest guest Posted January 16, 2004 Report Share Posted January 16, 2004 Speculations on drawing in: 1. The TA attaches to the thoraco-lumbar fascia which attaches to L-1--L-4 with a slight upward orientation. I have yet to see decisive evidence that, when actively engaged, the TA indeed increases spinal stability. The most movement in the lumbar spine occurs between L-4--S-1---this is also where most disc herniations occur in the lumbar spine. So, IF actively engaging the TA does in fact increase spinal stability, it would be from L-1--L-4, leaving even more work to stabilize the spine to be taken up by the most vulnerable/mobile segments of the lumbo-sacral area, L-4--S-1. 2. Contraction of the TA during inhalation impedes the diaphram from dropping down to allow the lungs to fully fill with air (about 30% less)--so, with regards to vigorous activity, my question is, how functional is that? If you can't breathe well, that negates the " functionality " context which " core stability " is so often applied to. 3. EMG activity in healthy populations indicate that the TA is a phasic muscle that works in frequency-opposition to the diaphragm with regard to breathing. If there is indeed a problem with TA recruitment, then go ahead and teach the person to actively engage it--however, I would not recommend applying such a technique to healthy population without a diagnosed TA deficiency whose TA functions normally.

Guest guest Posted January 16, 2004 Report Share Posted January 16, 2004 Hey , The draw-in technique is well documented in the book by , Carolyn, G. Jull, P. Hodges, J. Hides, Therapeutic Exercise For Spinal Segmental Stabilization In Low Back Pain, Churchill Livingstone, 1999. ISBN #: 0443058024. I strongly recommend the naysayers of the draw-in technique to at least take a look at the information in this book and then you can blast it all you want. It is also well documented in the scientific literature that if a joint presents with pain the surrounding musculature of this painful joint tends to weaken or becomes inactive entirely. Even once the pain is gone and the injured joint has healed the surrounding musculature continues to be weak or inactive until you strengthen it. That is where the draw-in technique comes into play for the athlete with an injured back. But, once the athlete can demonstrate adequate neuromuscular control of the lower abdominals then you integrate the technique into exercises (squats, lunges, deadlifts, overhead presses, etc...). Is it possible for an athlete to integrate the draw-in technique during subconscious activities? That remains to be seen. I saw Mike Boyle's presentation on the draw-in technique last year in Boston and noticed that he referenced Chek within the associated literature to the presentation. So I asked Mike what his thoughts were about the work that Chek has done in reference to core conditioning. He stated that had taken what the Australians had done with research and scientific studies of core conditioning and called it his own. Mike then went on to tell me that at a recent seminar that was speaking at went out of his way to question all of the other presenters about their training techniques and disrespected the strength and conditioning professionals at this seminar. I don't know exactly what had taken place at this seminar....but Mike was pretty fired up when he told me about it. The thing is everyone has a different spin on the same techniques. Mike uses taped hockey pucks and places them on the athletes navel as they draw-in the abdominals. uses the Janda technique with a blood pressure cuff to objectively measure the draw-in technique. They both have the athlete start out by laying down to perform the draw-in technique...then they progress to a standing draw-in. takes it a few steps further than Mike does. Who knows...... The only thing that I can suggest is do the research.....try the techniques on yourself and then draw your own conclusions. I hope this helps.

Guest guest Posted January 17, 2004 Report Share Posted January 17, 2004 Hello , I went to a seminar held by the rehab equipment company Perform Better back in 1999 in Boston and Mike spoke about abdominal hollowing techniques. During his talk he mentioned Chek's name is regards to the hollowing technique and activating the TVA, as if he ( Chek) was the main authority. Also at this seminar in the crowd was Mike Boyle. A couple of weeks later a friend of mine who works for a popular gym in the Boston area sat through a lecture by Mike Boyle, where Mike Boyle gave almost the same lecture as Mike e, except for a few different exercises variations. So from my limited experience in 1999, and from what I have read and heard the techniques and teaching are the same, outside of some exercise variation and of course coaching styles. It just seemed like during that year and currently any thing that is marketable is taken advantage of and blown out of proportion.

Guest guest Posted January 24, 2004 Report Share Posted January 24, 2004 Hi I have a few thoughts on the draw in technique & it's use for strength athletes. I attended a conference in Boston 2 years age presented by Dr. Hodges. He's one of the Aussie group based around Queensland Univ. who have actually done the developmental research that's lead to the use of the drawing in techniques being popularized by core training advocates. The thing about the draw in methods for the transverse abdominus that a lot of folks tend to forget, is that this method is activating a muscle whose action is primarily tonic (ie; a nearly constant but low level of activity). The function of these small muscles is to provide low amounts of force during usual daily activity such as walking or reaching into the refrigerator. Their role is vital as the maintenance of a small neutral zone around each intervertebral segment is a necessity for spinal health. However, in the athlete's world, much higher loads are produced with compressive & shearing forces that the average person cannot comprehend, much less tolerate. These loads require a concerted ability to generate stabilizing forces with integrated action of the core and more superficial, larger muscles. The research has shown that these muscles typically alter their patterns of activation in the presence of back pain or injury, usually delaying firing by a few hundred milliseconds. Altered patterns of activation are also seen in the larger erector muscles, again often in the form of timing difficulties. One must not forget the crucial role of the larger trunk muscles in the training of the athlete. Many exercises fire the multifidus & transversus along with the larger prime movers. These are also acceptable ways to train these muscles. The problem with the way some core training programs is that the athlete is left with the wrong emphasis. Total spinal stability requires all the players in the orchestra be in sync. Sincerely, Ernest Roy PT, CSCS Northfield, NH Quote Link to comment Share on other sites More sharing options...
