OBJECTIVE: To compare the effects of high- and low-velocity resistance training on functional performance and disability outcomes in physically limited older women. DESIGN: A total of 16 wk of high-velocity resistance training or traditional low-velocity resistance training consisting of knee extension and leg press exercises was performed three times per week by 30 women with self-reported disability to compare their effect on functional performance and disability. Tests of dynamic balance, stair-climb time, chair-rise time, and gait velocity were used to assess changes in functional performance. Changes in disability were assessed using the Medical Outcomes Study Short Form. RESULTS:Dynamic balance and stair-climb time improved 8% and 10%, respectively, with training. Self-reported disability, physical functioning, role physical, and mental health improved 11, 9, and 5% with training, respectively. There were no significant differences between high- and low-velocity training groups. CONCLUSIONS:High- and low-velocity training achieved similar improvements in functional performance and disability. Improvements in functional performance and disability were modest compared with robust increases in strength and power. Specific modes of training or behavioral strategies may be necessary to optimize improvements in these outcomes.
