What is the main purpose of hydration during physical activity?

• A. To increase muscle mass
• B. To maintain fluid balance and prevent dehydration
• C. To enhance endurance
• D. To improve flexibility

Answer: (B)

Hydration plays a crucial role during physical activity primarily by maintaining fluid balance and preventing dehydration. When engaging in exercise, the body loses fluids through sweat and respiration, which can lead to a decrease in performance and increased risk of heat-related illnesses if fluid levels are not adequately replenished. Staying properly hydrated helps to regulate body temperature, maintain blood volume, and support overall physiological function. It enables muscles to work efficiently and helps to transport nutrients effectively throughout the body. Therefore, the focus on maintaining fluid balance during physical activity is essential for optimal performance and health, making it the main purpose of hydration during these times.
