Physical weakness also leads to frailty of falls, dependently perform activities of daily living (ADL), threatens of public care insurance. Power is a potentially major etiologic factor in age-related functional decline. Power Rehabilitation(PR), a new resistance training regime, can improve in power and independence level of the elderly people. The first word of PR was in brief of Produce Outcome Worthwhile for the Elderly Rehabilitation (POWER). Purpose: (1)To investigate the effectiveness of PR training on muscle contraction velocity and power of older adults, (2)to investigate the effectiveness of PR training into improvement in ADL performance (FR & TUG). Design: single-blind, randomized controlled trial Subjects: 46 subjects aged above 65 years older adults, with ADL limitations. Methods: Participants were randomized into 2 groups. Experimental (n=23) group processed PR twice a week for 3 months whereas control group (n=23) did not. Both groups were measured in every 4 weeks. Accelerometer was used to stick on the weights of PR machines, to calculate the velocity, acceleration and power of subjects processed. The outcomes of physical performance were recorded by functional reach, sit-and-reach, timed up and go and 10-Meter Walk test. Result: (1)Peak muscle power significantly improved in the experimental group for all 6 machines (p<0.01).Within-group analysis revealed significant improvement, 136~524%, for all 6 machines of PR in the E-group. (2)The analysis revealed significant differences between the two groups for all 6 machines of PR. (3) Within-group analysis revealed significant improvement, 9.6~28.4%, for functional reach, sit-and-reach and TUG test in the E-group(p<0.05). (4)The analysis revealed significant differences between the two groups for TUG and timed 10m walk(p<0.01). Conclusion: After Power Rehabilitation training, the elderly would increase in power of physical, by mean of velocity, and ADL performances, e.g. FR and TUG. PR training might be a useful tool for rehabilitation and prevention of age-related declines in function. Although minor acquisition errors were present, accelerometers can provide a reliable and comparable means to assess muscle power.
