Skeletal muscle mass refers to the total weight of the skeletal muscles in the body. These muscles are responsible for movements, posture, and stabilizing the skeleton. This mass can be measured and is an important aspect of overall body composition, distinguishing muscle from fat and other tissues.
Skeletal muscle mass matters for health because it plays a significant role in physical strength, mobility, and endurance. Higher muscle mass is linked to better resilience and can impact survival rates, especially in older adults. Research suggests that maintaining good muscle mass can lower the risk of various health issues and improve quality of life.
The primary function of skeletal muscle mass involves enabling movement and physical activity. These muscles contract to allow for actions such as walking, lifting, and even breathing. Additionally, skeletal muscles help maintain metabolism and energy balance in the body, contributing to overall health and fitness.
It is important to monitor skeletal muscle mass as it can change due to factors like age, diet, and physical activity levels. Maintaining healthy muscle mass is vital for physical health and functional ability as one ages.
