What is one effect of aging on physical performance?

• A. Increased muscle mass
• B. Improved aerobic capacity
• C. Decline in flexibility
• D. Enhanced reaction time

Answer: (C)

As individuals age, one notable effect on physical performance is a decline in flexibility. This decline occurs due to various factors, including changes in connective tissues, muscle elasticity, and joint mobility. With aging, collagen becomes stiffer, and the elastic properties of muscles may diminish, leading to reduced range of motion in joints. This can affect overall performance in various physical activities, making movements more laborious and potentially increasing the risk of injury. The other options do not accurately reflect the typical physiological changes associated with aging. For instance, muscle mass generally decreases with age due to a reduction in physical activity and hormonal changes rather than increasing. Aerobic capacity also tends to decline as cardiovascular efficiency diminishes over time. Reaction times may slow as well due to changes in nervous system function. Thus, the decline in flexibility stands out as a common and significant effect of aging on physical performance.
