Yes he did. He also graduated early from HS to run the 400m hurdles and start spring football. He’s only a freshman, and he made some great plays in that WF game.
I understand many athletes have suceeded with various types of stretching routines but the scientist in me looks at the growing evidence about the (at least acute) detrimental effects of stretching on high power output movements and it makes me very cautious of using too much flexibility training, especially prior to competitive efforts. Also, understanding the mechanical properties of the muscle complex makes it hard for me to concieve how static or traditional PNF could enhance performance when used just prior to performance. Having said that, I do think there are plenty of good uses for various flexibility routines and I use some form of flexibility training everyday. Like I said though, I’m cautious in using it before competitive efforts. However, I do agree with Carl that the method, timing, and intensity of the stretch are probably the most important factors in determining its effects.
You could do PNF stretches for any muscle…just learn the protocols (hold-relax, hold-relax-contract, etc.) and voila…you’ve got limitless combinations. It’s great for spasm as Phoenix mentioned, and is perhaps the fastest way to increase flexibility, and can also be used for strengthening. It should be noted though that the benefits of PNF (the neuromuscular trickery if you will) are also its downfall when using if for athletics. That is, it will deminish power output (at least in an acute sense) more than any of the other stretching protocols
Well it definitely works for me, keep in mind that I’m getting it done over an hour before kickoff and prior to the high intensity elements of our warmup.
