Muscle mass plays a crucial role in longevity by impacting metabolic health, functional ability, hormonal balance, bone health, and inflammation regulation. Engaging in regular physical activity, particularly strength training exercises, can help maintain and build muscle mass, promoting overall health and potentially extending lifespan. 

 – **Metabolic health:** Higher muscle mass is linked to better insulin sensitivity, glucose metabolism, and lipid profile. This contributes to reducing the risk of chronic diseases like type 2 diabetes, cardiovascular disease, and metabolic syndrome, ultimately impacting longevity positively. – 

**Functional ability:** Strong muscles are essential for maintaining functional independence with age. Muscle strength is closely tied to physical function, balance, and mobility. Activities like strength training can help prevent falls, fractures, and injuries that can affect quality of life and longevity.

 – **Hormonal balance:** Muscles play a role in producing and regulating hormones like IGF-1 and myokines, crucial for cell growth, repair, and inflammation regulation. Healthy muscle mass supports optimal hormone levels, contributing to overall health and longevity. 

 – **Bone health:** Strong muscles support healthy bones by providing mechanical stress for bone growth. Maintaining muscle mass through weight-bearing exercises can prevent osteoporosis and fractures common in older adults, impacting longevity

. – **Inflammation and immune function:** Muscles produce anti-inflammatory myokines that regulate immune function and reduce chronic inflammation. 

By preserving muscle mass and reducing inflammation, individuals can improve overall health and potentially extend lifespan. Investing in muscle mass through regular physical activity, especially strength training, is a key component of a healthy lifestyle that can positively impact longevity and overall well-being.
