Final answer:
Sarcopenia is the age-related loss of muscle mass and strength, impacting strength, mobility, and independence in older adults.
Explanation:
Sarcopenia is the age-related loss of muscle mass and strength that occurs in later adulthood. It is characterized by a gradual decrease in the ability to maintain skeletal muscle mass, leading to symptoms like weakness and decreased physical activity.
Factors contributing to sarcopenia include a reduction in nerve cells signaling muscles, decreased protein-to-energy conversion, and inadequate calorie and protein intake. Preventative measures such as weight-lifting, walking, and swimming can help maintain muscle strength and prevent muscle atrophy.
Muscle loss not only affects strength and mobility but is also linked to frailty, falls, and fractures in older adults. Engaging in lifelong physical activity can aid in preserving muscle mass and overall musculoskeletal health.
