Answer: B - The recommended fluid intake during exercise is 7-10 ounces taken every 10-20 minutes. It is also recommended that individuals drink 17-20 ounces 2 hours prior to exercise. An interesting fact: Individuals who exercise in a vertical position in water will actually lose their natural thirst drive, even if they were thirsty prior to immersion. Why? During upright immersion, hydrostatic pressure drives fluid from the legs to the chest. This migration results in the body’s volume receptors cueing the brain that the body has too much volume; this results in an increase in urination and a decrease in thirst.
