The hydration guideline recommends drinking approximately how much water before exercise?

1. 200-300 ML

2. 500-600 ML

3. 800-1000 ML

4. 100-200 ML

The correct answer is: 500-600 ML

Drinking approximately 500-600 milliliters of water before exercise aligns with hydration recommendations that emphasize the importance of maintaining fluid balance. This quantity ensures that the body is adequately hydrated prior to physical activity, allowing for optimal performance and reducing the risk of dehydration. Research suggests that consuming this amount of water about two to three hours before exercising helps the body to absorb the fluids effectively, which is crucial for maintaining athletic performance. Adequate hydration also helps to regulate body temperature and maintain cardiovascular function during exercise. In contrast, smaller amounts of fluid may not provide sufficient hydration for more intense workouts, while larger quantities could potentially lead to discomfort or the need for frequent bathroom breaks, which can distract from the flow of an exercise session. Thus, the recommendation of 500-600 milliliters strikes a practical and effective balance for pre-exercise hydration.
