Guest guest Posted July 3, 2003 Report Share Posted July 3, 2003 As someone who's studied under Chek in the past, I thought I should chime in here and give my two cents. First off, is a great guy and I have nothing against him personally. However, after thousands of dollars spent on his videos and his internships I'm absolutely convinced that (and the NASM)is wrong about the TVA thing. For someone who is so into integrated(anti-isolation) training, he sure goes out his way to glorify the isolated recruitment of the transversus abdominus. To help get my point across I will use an excerpt from Stuart McGill's excellent text: LOW BACK DISORDERS Evidence-Based Prevention and Rehabilitation(which by the way is a much more scientifically plausible text the and Jull's). The initial question posed and McGill's response are as follows: " Is any single muscle most important? Several clinical groups have suggested focusing on only one or two muscles to enhance stability.....in particular, clinical groups have emphasized the multifidus and and transverse abdominus. The Queensland group( and colleagues) performed some of the original work emphasizing these two muscles. This was based on their reseach, which noted motor disturbances in these muscles following injury...The intentions of the Queensland group were to address the documented motor deficits and attempt to reduce the risk of aberrant motor patterns that could lead to pathology-inducing patterns in their damage model. In other words, their recommendations appear to be directed toward re-educating the faulty motor patterns. However, many clinical groups have interpreted this approach to mean that these two muscles should be the specific targets when teaching stability maintenance over all sorts of tasks... " McGill than goes on to conclude: " In summary, achieving stability is not just a matter of activating a few targeted muscles, be they multifidus, transverse abdominus, or any other. Sufficient stability is a moving target that continually changes as a function of the three-dimensional torques needed to support postures. It involves achieving the stiffness needed to endure unexpected loads, preparing for moving quickly, and ensuring sufficient stifness in any degree of freedom of the joint that may be compromised from injury. " McGill's statement on the Australian research folly makes the most sense to me. McGill has even done research which shows that spinal stability is lowered when patients are taught to " hollow " their abdomen (isolated TVA recruitment) versus " abdominal bracing, " which recruits all the layers of the abdominal wall(external oblique, internal oblique, and TVA). Abodminal bracing doesn't mean pushing your abs out or pulling them in. It is more of a isometric contraction as if bracing for a punch into the stomach. Pavel Tsatsouline teaches this as well and using bracing technique my back feels much healthier than when I was doing that stupid hollowing nonsense. In fact, I had constant low-back isssues when I was exclusively using 's techniques on improving my so-called " segmental stabilization. " As a sprinter I was killing my back my trying to let me my " inner unit " do all the work. What a joke! Now I'm stronger than ever and don't even think about my abs much when working out. As long as I hold my breath appropriately when lifting or sprinting my body takes care of the rest. Now this is not to discount TVA isolation exercises for those people who have true spinal pathologies; there is a place for the vaccum exercises, just don't teach people to consciously recruit their TVA during dynamic movement. It's no more ridculous than telling someone to only use their supraspinatus muscles during arm abduction!

Guest guest Posted July 4, 2003 Report Share Posted July 4, 2003 Well Keats...I couldn't have put it better myself! That should just about end this enduring discussion!
