What is the recommended fluid intake before exercise?

200-300 mL
500-600 mL
750-950 mL
1000-1200 mL

The correct answer is: 500-600 mL

The recommended fluid intake before exercise is typically around 500-600 mL. This amount is generally advised because it helps to ensure that the body is adequately hydrated prior to physical activity, which can enhance performance and reduce the risk of dehydration. Hydration plays a crucial role in maintaining optimal physiological functions, such as temperature regulation and cardiovascular efficiency, particularly during exercise. Drinking this volume about two to three hours before exercise allows for proper absorption and can help mitigate the risk of having a full or uncomfortable stomach during the workout. Additionally, pre-exercise hydration aids in maintaining blood volume and electrolyte balance, which are essential for effective muscle function and endurance. It's important to consider individual factors such as body size, climate, and exercise intensity, but the 500-600 mL range is a well-supported guideline in exercise and sports nutrition literature.
