3 M: 3-Month Follow-up; 9 M: 9-Month Follow-Up; BL: Baseline; CST: Chair Stand Test; PAR-Exercise: Physical Activity Recall-Exercise; PAR-Flexibility: Physical Activity Recall-Flexibility; PAR-Strength: Physical Activity Recall-Strength; PT: Posttreatment; Walk 4M: 4-Meter Walk Test; Walk 50FT: 50-Foot Walk Test.

Computed using 7-Day Physical Activity Recall. Variable represents a sum of the total time spent engaging in the specific activity (strength training, flexibility exercise, or at least moderate exercise) per 7-day period.
