Yep, that's one of the main reasons why extended halftimes are a really bad idea. Muscles start tightening up again, and that leads to needless injuries. I wonder if the NFLPA or even the league itself has ever studied this, because I'd bet that dollars to donuts that the majority of hamstring pulls and other muscle related injuries occur early in the third quarter following extended halftimes.
