The Seattle FICSIT/MoveIt study: the effect of exercise on gait and balance in older adults

While exercise is generally recommended for older adults, the specific role of exercise in preventing falls and frail health is unclear. The Seattle FICSIT/MoveIt study is a population-based, randomized, controlled trial comparing the effects of three 6-month exercise interventions (endurance training, strength training, or combined endurance and strength training), and three 3-month endurance training interventions (stationary cycle, walking, or aerobic movement). Primary study outcomes are aerobic capacity, strength, gait, balance, and physical functional status. The study enrolls adults age 68-85 who have leg weakness and impaired gait. It differs from most previous community-based exercise studies in several respects: recruitment of subjects from a defined population; eligibility criteria based upon physiologic and functional status deficits; random assignment to exercise groups; assessment of both physiologic and functional status outcomes; follow-up beyond the completion of supervised exercise; and a large sample size (Total N = 180).
