What is the term for the age-related loss of muscle mass?

The age-related loss of muscle mass is termed sarcopenia. This condition is characterized by a gradual decline in muscle strength, mass, and function as individuals age, which can significantly impact mobility and overall health. Sarcopenia is particularly noteworthy because it can lead to increased frailty and a higher risk of falls and injuries in older adults. The concept emphasizes the importance of maintaining muscle health through physical activity, nutrition, and other interventions as people age to mitigate the effects of sarcopenia.

Understanding sarcopenia is crucial in the field of fitness and health, especially for trainers and health professionals working with older populations, as it informs strategies for effective strength training and nutrition programs aimed at preserving muscle mass and function.
