Abstract Background Although progressive resistance strength training ST has been found to improve various measures of physical functioning in older adults the benefit to quality of life is unclear. Additionally recent evidence suggests that high velocity power training PT may be more beneficial for physical functioning than ST but it is not known whether this type of training impacts quality of life. The purpose of this study was to compare changes in multiple measures of quality of life resulting from ST vs. PT in older adults. A no exercise group was also included as control comparison condition. Methods Forty-five older adults M age years SD were randomly assigned to either a PT b ST or c control group no exercise . Measures of self-efficacy SE satisfaction with physical function SPF and the Satisfaction with Life Scale SWL were assessed at baseline and following training. The resistance training conditions met 3 times per week for 12 weeks at an intensity of 70 1 repetition maximum. Results A
