Post-workout hydration should be completed to replace what percentage of fluid loss?

The correct answer, which indicates that post-workout hydration should aim to replace about 150% of fluid loss, is based on the body's needs following exercise. During physical activity, especially intense or prolonged workouts, the body loses fluids primarily through sweat. Replacing not just the lost fluids, but also additional fluid—specifically 150% of the fluid loss—is important because it takes into account the natural tendency for the body to continue losing fluids after exercise ends.

This extra hydration helps to ensure that the body is fully rehydrated and can also account for ongoing sweat losses that may occur even after the workout is complete. It supports recovery by replenishing electrolytes and maintaining proper hydration status, which is crucial for optimal recovery, physiological function, and performance in future workouts.

If the goal were simply to replace 100% of fluid loss, it could leave the body slightly dehydrated afterward, especially given factors like any additional fluid loss due to perspiration post-exercise and individual variances in rehydration ability. Therefore, aiming for a higher percentage, such as 150%, is a more effective strategy to ensure full recovery.
