The role of hydration in muscle function is crucial, as water is essential for maintaining cellular homeostasis and optimal muscle contraction. Proper hydration aids in nutrient transport, temperature regulation, and overall performance during exercise. Dehydration can lead to decreased strength, endurance, and exercise recovery, significantly impacting physical output. Adequate fluid intake supports muscle function and helps prevent cramps and injuries, while proper hydration before, during, and after workouts enhances athletic performance and overall well-being.
