Hydration critically impacts athletic performance and recovery. Proper fluid intake is essential for maintaining optimal body function during exercise, as dehydration can lead to decreased endurance, strength, and coordination. It can also adversely affect cognitive function, increasing the risk of injuries or accidents. Post-exercise hydration aids in muscle recovery, helping to replenish lost fluids and electrolytes. Ensuring adequate hydration supports metabolic processes and can improve overall training outcomes, making it a key component of any fitness strategy.
