β = unstandardized beta coefficients; Δgait speed in 400 m walk = gait speed at each visit minus gait speed at first visit; Δpeak torque (Nm) = peak torque at each visit minus peak torque at first visit; ΔALM (kg) = appendicular lean mass at each visit minus ALM at first visit; Δfat mass (kg) = whole‐body fat mass at each visit minus whole‐body fat mass at first visit. SE, standard error.

All models were adjusted for race (Black vs. non‐Black), baseline age, baseline gait speed, baseline height, and baseline gait speed. In addition, Model 1 was further adjusted for baseline peak torque. Model 2 was adjusted for baseline ALM and fat mass. Models 3 to 7 were adjusted for baseline peak torque, ALM, and fat mass. Of note, no significant associations were observed between these covariates and Δgait speed in any models (P < 0.05).
