Exam 10: Physical Activity- Thermoregulation

Women show heat tolerance similar to that of men of equal aerobic fitness at the same physical activity level.

Relative humidity has no impact on the effectiveness of evaporative heat loss.

Full heat acclimatization cannot take place without exposure to environmental heat stress.

Not a benefit associated with hyperhydration to help protect the athlete against heat stress before exercising in a hot environment?

Adding salt to food facilitates rehydration.

Excessive internal heat buildup dilates peripheral vessels that channel warm blood to the cooler periphery.

Provides "fine tuning" for temperature regulation.

Hormone that decreases sodium concentration in sweat, which aids in electrolyte conservation.

Aldosterone facilitates sodium absorption by the small intestine.
