How much fluid should be consumed after exercise per kilogram of weight lost?

1. 100-200 mL

2. 250-500 mL

3. 450-675 mL

4. 700-900 mL

The correct answer is: 450-675 mL

The recommended fluid intake after exercise is important for rehydration and recovery. Consuming 450-675 mL of fluid per kilogram of weight lost is based on research that indicates this amount is sufficient to replace fluids lost through sweat and other physiological processes during physical activity. This range takes into account variations in individual sweat rates, the intensity and duration of exercise, and environmental conditions. Rehydrating effectively helps restore fluid balance in the body, supports optimal cardiovascular function, and aids in the recovery process. It’s essential to compensate for each kilogram of weight lost to ensure the body can return to its normal hydration levels post-exercise. Additionally, consuming fluids within this range helps prevent conditions such as dehydration, which can adversely affect performance and health. Other ranges may not provide enough fluid to adequately replace what is lost, which can lead to suboptimal recovery and performance in subsequent workouts. Therefore, adhering to this guideline ensures athletes can maintain hydration and support their overall fitness journey.
