What is a common effect of aging on muscle mass?

• A. Aging increases muscle mass
• B. Aging does not affect muscle mass
• C. Aging typically leads to decreased muscle mass and strength
• D. Aging results in enhanced muscle flexibility

Answer: (C)

Aging typically leads to decreased muscle mass and strength due to a natural process called sarcopenia, which is the gradual loss of skeletal muscle associated with aging. This decline begins around the age of 30 and accelerates with advancing age, particularly after the age of 60. Factors contributing to this loss include hormonal changes, decreased physical activity, and changes in muscle fiber composition, leading to a reduction in both the size and number of muscle fibers. The decrease in muscle mass can also affect overall strength and functional performance, making it more challenging for older adults to maintain independence in daily activities. This phenomenon is widely recognized in medical and fitness literature, making it a significant concern in geriatric health and wellness.
