Laugh if you will, downvote if you must, but, as with many things, I trust to my dogs' opinion in the matter: they stretch before physical activity, and so do I (for other reasons of course too). I don't dispute the short-term performance gains by not pre-stretching, but is there a long-term cost? With performance gains in any system, there are usually trade-offs. If I were in a race to win a million dollars, you can bet your ass I'm not stretching beforehand based on all this research, but what about before my light daily jog? I feel all rickety sometimes if I don't. I'd be interested in a history of stretching, specifically before physical activity. Evolutionary precedent has a way of shedding light on these sticky questions. For example, what kind of warm-ups or stretching did cavemen do before a mammoth hunt?
