Alterations in gait speed and age do not fully explain the changes in gait mechanics associated with healthy older women

Highlights ► Regression statistics assessed the variance in gait attributable to speed and age. ► Annual losses of 1.2%/year in natural gait speed were predicted by age in older women. ► Yearly declines in foot clearance may contribute to the rising fall risk with age. ► A proximal shift in mechanic...

Description
Summary:Highlights ► Regression statistics assessed the variance in gait attributable to speed and age. ► Annual losses of 1.2%/year in natural gait speed were predicted by age in older women. ► Yearly declines in foot clearance may contribute to the rising fall risk with age. ► A proximal shift in mechanical demands from the ankle to hip was observed pre-swing. ► Exercise interventions for older women should improve/retain hip and ankle function.
