Why do athletes drink water during exercise?
Show answer & explanation
Answer: To replace lost fluids
To wash away sweat — Wrong. Water goes inside your body, not on your skin. Sweat evaporates naturally or can be wiped away.
To replace lost fluids ✓ — Correct! Sweating removes water from your body—up to 2 liters per hour! This water must be replaced to maintain blood volume, regulate temperature, and deliver nutrients to muscles. Even 2% dehydration hurts performance!
Water dissolves muscle fatigue — Wrong. Fatigue isn't a substance that water can dissolve. Muscle fatigue comes from energy depletion and metabolic byproducts—water helps with temperature regulation and nutrient transport.
