Which of the following is a manifestation of improved physical fitness related to older adults?

Improved balance is a significant manifestation of enhanced physical fitness in older adults. As individuals age, maintaining physical activity and engaging in exercises designed to improve strength, flexibility, and coordination can lead to noticeable improvements in balance. This is crucial for older adults as it helps reduce the risk of falls, which can lead to serious injuries. Better balance supports greater independence and enhances overall quality of life, allowing older adults to engage in daily activities with more confidence and security.

In contrast, the other choices do not reflect positive outcomes of physical fitness. For instance, higher cholesterol levels are typically associated with poor dietary choices and lack of exercise, rather than improvements in physical health. Decreased mobility contradicts the benefits of physical fitness; regular exercise should foster increased mobility and functionality. Increased forgetfulness can indicate cognitive decline, often exacerbated by sedentary lifestyles, again not associated with the positive effects of improved physical fitness. Thus, improved balance stands out as a clear indicator of the benefits gained through physical activity in older adults.
