Which of the following is true regarding water metabolism during exercise? a. Water loss of greater than 1 percent can decrease capacity to do muscular work. b. Sweat losses can exceed the capacity of the GI tract to absorb water, resulting in some degree of dehydration. c. The maximum loss of fluid per hour of exercise is about 0.5 liters. d. In cold weather, the need for water falls dramatically because the body does not sweat. e. Heavy sweating leads to a marked rise in the thirst sensation to stimulate water intake, which delays the onset of dehydration.
