Which of the following is a successful strategy for hydration during exercise?

Drinking sports drinks when exercising for over one hour is a successful strategy for hydration during exercise because these beverages are designed to replenish not just fluids, but also electrolytes and carbohydrates that are lost through sweat during prolonged physical activity. When exercise extends beyond one hour, maintaining hydration becomes increasingly important, and water alone may not provide sufficient nutrients to sustain energy levels and electrolyte balance. Sports drinks typically contain sodium, potassium, and other electrolytes that help prevent hyponatremia and facilitate optimal hydration and performance.

This approach is particularly beneficial for endurance athletes or those participating in extended training sessions, as it helps to maintain stamina and performance by ensuring that the body's hydration and energy needs are met effectively during prolonged periods of exertion.
