Got a question though, about the stretching vs strength thing, could you elaborate on that a bit more? Or link to a good article on it? I want to be strong and crazy flexible and I am working on both. The book kind of glosses over the actual mechanics of it.
Going back and looking at that section, I’m surprised at my lack of citations for that information. It’s become so commonplace in modern fitness that it must not have occurred to me, despite upsetting the applecarts of pretty much every middle-school coach in the US.
I’m not entirely sure how much information you were looking for. Here’s a few of the articles I possibly should/would have cited (and likely may if I should do a second edition down the road).
Reduced strength after passive stretch of the human plantarflexors (Journal of Applied Physiology, 2000)
Acute effects of static versus dynamic stretching on isometric peak torque, electromyography, and mechanomyography of the biceps femoris muscle (Journal of Strength and Conditioning Research, NSCA, 2008)
Effects of Static Stretching on Energy Cost and Running Endurance Performance (Journal of Strength and Conditioning Research, NSCA, 2009)
If you were looking for something perhaps more accessible, there was a pretty good article in the NY Times’ Play Magazine not too long ago.
Anyway, though I was attempting to keep the book brief and concise, I still feel like I might have done a better job in that section. I’m not opposed to all static stretching. The example most obvious to me is the various forms of Yoga poses that hold positions, which in themselves may be valuable to health, strength, and/or flexibility. However, I wouldn’t bolt off and try to perform a workout immediately following yoga, or to use yoga as a ‘warm-up’ for resistance or interval exercise.
The objective of that section was to get people away from the longstanding notion of doing five or ten different held stretches in an attempt to ‘get ready’ for exercise, and to alternatively provide readers with a method for ‘warming-up’ the muscles and body, without depleting or inhibiting their muscular performance for what would come after.
Do you have any videos or animations for the “pull squat dynamic stretch” you mention in the book? I can’t visualize it and there’s nothing on google about it.
