Sweat Not Only Keeps You Safe During a Workout, it Improves Performance

from The Washington Post

"No sweat, no glory."

"Sweat is fat crying."

"Good things come to those who sweat."

These are popular mottos among the fitness set. But is there any truth to them? Is sweat really a sign of fitness? Do athletes sweat more?

Yes, so embrace it.

"Sweating is one of the best methods of cooling the body," says Max Prokopy, director of the University of Virginia SPEED Clinic.

Sweat is a byproduct when the body heats up to convert chemical (glucose) energy to work (muscle) energy, Prokopy says. Sweat helps keep the body temperature between 98 and 103 degrees Fahrenheit no matter how intense the workout.

"Performance really starts to suffer at 103," he says. And if you reach 104 degrees you are risking heat exhaustion or worse. more
