This randomized, parallel-group clinical trial evaluates a 12-week adapted CrossFit program versus usual activity in community-dwelling older adults. The primary endpoint is change in Timed Up and Go (TUG) from baseline to 12 weeks. Secondary outcomes include Functional Reach (FRT), Romberg (eyes closed), gait velocity, stride length, and lower-limb power tests (Chair-Stand, Stair Ascent, Stair Descent; time and W/kg). Sixty participants were randomized (1:1). Analyses used repeated-measures ANOVA with Bonferroni adjustments and Cohen's d effect sizes.
