Which of the following statements about water and muscle function is true?

Water plays a crucial role in maintaining muscle function and overall physical performance. When the body is well-hydrated, muscles can effectively contract and relax, which is essential for optimal performance during any physical activity. Adequate hydration improves circulation and helps maintain electrolyte balance, both of which are vital for muscle pliability and function.

When muscles are hydrated, they remain flexible and capable of working efficiently, which is key in preventing cramping and reducing the risk of injuries. Staying hydrated also supports nutrient transportation to the muscles and removal of metabolic waste, further enhancing muscle recovery and performance.

In contrast, statements suggesting that water can lead to muscle stiffness or should be avoided during exercise do not align with the well-documented benefits of hydration. Moreover, the notion that water has no role in muscle conditioning overlooks the fundamental physiological processes that depend on water for optimal muscle activity. Thus, emphasizing the importance of water in keeping muscles pliable reflects the significant physiological benefits of hydration for muscle function.
