Quote:Caldwell says the two things that worry him about training camp are injuries and the heat. I definitely agree with number one - injuries are my main worry too. But is heat really an issue these days? Don't they have hydration down to a science?

 

It is an applied science. Gatorade are developing these new water bottles that can track how much of a drink is consumed, I don't know if teams are using it yet. But so far there is no way to measure how much water is lost other than weighing someone before and after practice. The issue is you don't know when someone has crossed a dehydration or heat-related threshold in the middle of practice, unless you can see it on the heart-rate monitors (which you can't because they aren't reliable enough).
