I would hope coaches would take their teams to the shade in the extreme temps. It shows they are being responsible. I'm glad IrontigerMum posted. Your son was the first one I thought of. Very dangerous situation for him one summer.
Having run 13 marathons and 4 ultramarathons(50k.....31 miles), I have a pretty good idea of what good conditioning is. I have trained very hard at times and at other times LET THE WEATHER determine how I was going to run that day. Anytime you are involved in an activity which is strenuous, paying attention to the weather conditions that day are of utmost importance. There were many days that I was physically and mentally ready to go for a 20 mile training run, but it was simply too hot or humid to run that far without a significant risk of heat illness.
I am not familiar with the particulars of football conditioning, but I do know that some of it involves running. Running in hot weather is VERY STRENUOUS and should be monitored very carefully.......even the kids who are in good shape to begin with.
The point that I tried to make above was that there are fewer and fewer kids these days who are in really good shape when football training starts.......it is a statistical fact that kids today have more body fat and live more sedentary lives than their counterparts from a generation ago. And today there are more and more kids suffering some sort of heat illness in football training as a result. What is troublesome is that there are kids today who cannot handle even a beginning level of conditioning without becoming overly fatigued. There are times when kids get tired even BEFORE the point of hydration should be done.......that is inexcusable and points to a lack of committment of that individual in the offseason. It should not be up to the coach to get a kid in shape in the offseason.......the individual has to own up to his end of the responsibility. A kid should be able to take 30 minutes a day, several days a week, to run or whatever to get himself in reasonable shape. That is not a big time investment, but the dividends that it will pay will be well worth it.
Hydration during football training is routine........or at least SHOULD BE.....taking in water or sports drink is extremely important and should NEVER be avoided by any coach or player. Limiting hydration is putting a kid in an extreme situation for which his body is most likely not capable of tolerating for a considerable amount of time. It certainly should never be considered weakness because a kid took the time to hydrate himself.......that is the smart and prudent method that will increase conditioning in the long term because it will help him to perform strenuous activity for a longer portion of time.
Caglewis is absolutely right........hydrating one's self is not weakness.......but it is not very smart to come to football conditioning in subpar shape and then expect the coach to "whip" that kid into shape.
It makes the coaches' job of conditioning a football team much easier if the kids he is responsible for would make a reasonable effort of their own in the offseason.
Nobody ever told me to get out of the house and go do a marathon training run. I did them all on my own. I wanted to do them and I knew what the benefits would be from doing them. And in the end I finished all the marathons that I entered with a best of 2:55..........
