Older adults' gait speed is generally what percentage slower than that of younger people?

Older adults typically exhibit a decrease in gait speed due to various factors including age-related physiological changes, decreased muscle mass, and potential balance issues. Research indicates that, on average, older adults' gait speed can be approximately 20% slower than that of younger individuals. This reduction in speed is significant as it may impact their ability to perform daily activities, maintain independence, and overall quality of life. Understanding this statistic is crucial for exercise physiologists when developing appropriate exercise programs aimed at improving mobility and reducing fall risk among older adults.
