Which accounts for the largest amount of water loss in an athlete exercising in the heat?

Question

Quizplus · Accepted Answer

When an athlete exercises in the heat, the majority of water loss occurs through sweat and evaporation from the skin. This is because sweating is the primary mechanism the body uses to regulate body temperature during exercise, and in hot environments, more sweat is produced to maintain a safe body temperature. Feces and urine typically do not account for significant water loss during exercise, and while some water is lost through respiration, it is usually a small fraction of the total water lost during exertion in the heat.
