What percentage of water do muscles contain?

Muscles are composed of approximately 70% water, which plays a crucial role in maintaining their function and overall health. Water is vital for numerous physiological processes, including nutrient transport, temperature regulation, waste elimination, and muscle contraction. This high water content also contributes to the muscle's volume and mass, affecting physical performance and endurance.

In terms of hydration, muscle tissue relies on adequate water intake to sustain optimal conditions for exercise, enhance recovery, and improve performance. Staying well-hydrated helps to mitigate fatigue and cramping, thereby allowing for more effective workouts. This understanding underscores the importance of both hydration and nutrition for individuals looking to improve their muscle health and athletic performance.
