What is the water content of muscle estimated to be as a percentage of its total weight?

Muscle tissue is typically composed of a significant amount of water, which plays a crucial role in various physiological functions, including nutrient transport, temperature regulation, and as a medium for biochemical reactions. The correct estimation of water content in muscle is around 74% of its total weight. This high percentage highlights the importance of hydration for maintaining muscle function and overall athletic performance.

Understanding the composition of muscle can help trainers and clients appreciate the role of water in fitness and recovery. While muscle does contain some percentage of protein, carbohydrates, and other substances, the predominance of water is key to facilitating cellular functions and optimizing physical activity. The percentages given in the other options are either too low or too high when compared to the generally accepted figures found in exercise science literature.
