Hydration plays a crucial role in athletic performance, as even mild dehydration can impede physical capabilities. Staying well-hydrated enhances endurance, strength, and overall function during exercise. Proper hydration supports thermoregulation, lubricates joints, and aids nutrient transport, directly influencing energy levels and performance metrics. Athletes should monitor fluid intake before, during, and after activity to maintain optimal hydration status, thus maximizing their athletic performance and reducing the risk of fatigue and injury.
