There's a science to staying cool in the heat -- and NCAA trainers have a regimen.
The NCAA has incorporated heat acclimation into football training schedules.
The idea is to allow the body time to build up plasma levels in order to stay hydrated in the heat.
Most high school football programs lack similar regimens to avoid overheating among its players.
As football season heats up, so will the thousands of players hitting the field for practice. But the problem, researchers say, isn't the players' performance -- it's their body temperatures.
Heat acclimation, or training the body to better adapt to heat during exercise, has found its way into the NCAA's regulations for football players. At present, teams are required to hold less intense practices once per day for seven to 10 days in the heat before transitioning into more intense schedules with more than one practice per day.
But how does the process actually work?
Christopher Minson, associate professor and head of the University of Oregon department of physiology, told Discovery News that in order to understand heat acclimation, one should first tackle thermoregulation, or how the body cools itself. Blood usually carries heat away from active muscles to the surface of the skin, where sweating takes over.
