Explanation / Answer

Changes in body weight after drinking water or after an activity are a good measure of hydration status. But this method is reliable only for short duration of time.

This person weighs 180 pounds before the endurance exercise. After the endurance exercise, the body weight becomes 184 pounds. So, there is 4% increase from baseline.

So, the correct answer is d) “4% hyper-hydrated.”
