I suggest you watch a little TV on NBC over the next couple of weeks. There's a few fairly well trained athletes competing in temperatures less than 37F and not having problems with their muscles or motor skills. It's the Winter Olympics, are you sure you want to stick with your diatribe? If you train and dress properly you can excel in fairly cold temperatures.
Really, your going to compare older olympic athletes with the best trainers, coaches, nutrition, doctors the sporting world has to offer with a bunch of young high school pitchers with one inexperienced coach.... ha
Olympic winter athletes are conditioned for many many years in the temps they compete in, hardly a fair comparision.
Also, there is a limit as fas as pitches and innings a HS player should throw during a high school season according to Dr. Andrews.
