Tag: Muscle water content

While some sources claim muscle is 90% water, the true percentage is actually lower, sitting between 70% and 75%. This common misconception underestimates the role of other components like protein and glycogen while overstating water's contribution to muscle mass.

According to the U.S. Geological Survey, muscle tissue contains approximately 79% water, which is significantly higher than fat tissue at around 10%. This high concentration of water in muscle is a critical factor for numerous physiological functions and has a profound impact on athletic performance and overall body composition.
