The purpose of the present study was to investigate the effects of strength and power training on the functional abilities of older adult subjects. Thirty-two male (n=7) and female (n=25) volunteers (74+/-6.2 yrs) participated in this randomized controlled trial of 12-wks duration. All groups performed 3 sets of 10 repetitions on 6 pneumatic resistance machines 3 days per week for 12 weeks. The high-velocity 70% 1RM group (70% Fast, n=11) and the high-velocity 50% 1RM group (50% Fast, n=8) performed the exercise movements as quickly as possible during the concentric portion of the movement. The low-velocity 70% 1RM (70% Slow, n=13) group performed the exercise movements in a slow and controlled fashion (2-3 sec) during the concentric portion of the movement. Leg press strength, peak power and average peak power were assessed using a computerized pneumatic system. Functional performance was assessed from a 50' fast walk test, a 30-sec chair stand, an 8-ft up-and-go timed test (TUG), the Berg Balance Scale (BBS) and the Activities-Specific Balance Confidence Scale (ABC) before and after the 12-wk intervention. There were main effects of time (p≤.05) for leg press strength, peak power, average peak power, BBS, 50' fast walk and 30-sec chair stand. There were no main effects for group. Significant interactions were found only for the ABC and 50' fast walk. Post-hoc analyses revealed that the 70% Fast group declined significantly (p≤.05) on the ABC and increased significantly on the 50' fast walk test (p≤.05). Partial correlations at baseline, when controlled for age, revealed significant relationships between peak power and average peak power with all measures of functional abilities accounting for 20-24% of the variance in performance. Leg press strength, when controlled for age, was significantly correlated only with performance on the 30-sec chair stand test. In conclusion, high-velocity and low-velocity training improved functional performance. Although the relationship between power and function was strong the added benefits of training at higher velocities remain equivocal.
