Task Specific Timing and Coordination Exercise to Improve Mobility in Older Adults: Program to Improve Mobility in Aging

This randomized clinical trial targets 248 community-dwelling older adults with impaired mobility (i.e. walking slowly; gait speed \< 1.20 m/s). The trial compares a 12 week \"standard-plus\" program of strength, endurance, flexibility plus task specific timing and coordination training to a standard 12 week strength, endurance and flexibility program. The primary outcome is gait speed at 12 weeks. Secondary and tertiary outcomes represent components of the intervention and measures of activity and participation. Delayed and sustained effects of the intervention are examined at 24 and 36 weeks.
