Hydration plays a crucial role in muscle function and performance. Adequate fluid intake is necessary for maintaining optimal blood volume, which supports nutrient transport and waste removal. Dehydration can lead to decreased strength, endurance, and overall exercise capacity. Additionally, water helps regulate body temperature during physical activity, preventing overheating. Maintaining hydration before, during, and after workouts is essential for sustaining energy levels and enhancing recovery. Optimal hydration practices can improve athletic performance and support overall health.
