I read a few studies that showed that stretching actually increased injury rates significantly (well beyond the margin of error in all studies done).
I was a coach and PE teacher for a while and eliminated the 20 minutes of stretching we were told to do, and just did what the studies suggested and did slower versions of the main movements to "warm up" instead. Repetitions of the primary actions basically (just as you see NFL players do during warm-ups out on the field and baseball players do in BP before the game).
I found a significant drop in injury and a significant improvement in performance. I tried it for 5 years myself after being an ardent stretcher and constantly injured athlete, and in that five year span didn't tear, stretch, or strain anything. The one thing that happened was a broken ankle from a direct karate kick by an opponent. Stretching wouldn't have changed that. But I also saw my own performance improve. I went from a fair to middling baseball/softball player, to one who moved up two ranks nationally to B level, which is where college baseball/minor league baseball level players are classified. So past my prime years without stretching I went from D to nationally ranked B. Just one small scale experiment, but it worked for me, and it worked for the teams I coached at all different age levels, and also for the classes I taught where we were having constant hamstring and calf and knee issues along with abdominal and back strains after the district's prescribed 20 minutes of stretching. It was pretty amazing.
