Scientists identify animal model to study human musculoskeletal aging
There are many components to aging, both mental and physical. When it comes to the infrastructure of the human body - the musculoskeletal system that includes muscles, bones, tendons and cartilage - age-associated decline is inevitable, and the rate of that decline increases the older we get. The loss of muscle function and often muscle mass is scientifically known as sarcopenia or dynapenia.
For adults in their 40s, sarcopenia is hardly noticeable about 3% muscle mass is lost each decade. For those aged 65 years and older, however, muscle decline can become much more rapid, with an average loss of 1% muscle mass each year. More importantly, sarcopenia is also marked by a decrease in strength, impaired gait, reduced physical activity, or difficulty completing everyday tasks.
