Muscle aging, also known as sarcopenia, is a condition characterized by a loss of muscle mass and strength that occurs with aging. This can lead to decreased physical function, increased risk of falls and fractures, and overall reduced quality of life. Researchers study muscle aging to understand the underlying mechanisms and develop interventions to prevent or reverse the decline in muscle mass and function associated with aging. This research often involves examining changes in muscle structure and function, as well as exploring potential treatments such as exercise, nutrition, and pharmacological interventions.
