Strength training in older adults: an empowering intervention.
PURPOSE This study evaluated the benefits of adding a psychological empowerment intervention ( PEI ) to traditional strength training ( TST ) on social cognitive variables in community-dwelling older adults . METHODS Thirty-eight participants were r and omly assigned to either a PEI or a TST intervention for 6 wk . Before r and om assignment and following training , participants completed measures of self-efficacy for upper and lower body strength as well as the desire to be able to lift specific amounts of weight . Both treatments involved two sessions per week of center-based training and one session per week of home-based training . The PEI condition also included a group-mediated intervention that was design ed to increase self-efficacy for physical strength and the desire for upper and lower body strength . RESULTS General linear models on difference scores revealed that the two groups experienced differential gains in the desire for upper body strength ( P = 0.023 , effect size ( ES ) = 0.79 ) and were marginally different in gains for upper body strength self-efficacy ( P = 0.065 , ES = 0.63 ) . On a four-point scale , the adjusted mean ( + /-SE ) differences for the PEI group on the desire for upper body strength was 0.71 ( + /-0.12 ) as compared to 0.27 ( + /-0.13 ) for the TST group , whereas the PEI group 's improvement in self-efficacy for upper body strength was 25.70 ( + /-3.02 ) as compared to 17.18 ( + /-3.19 ) for the TST group . CONCLUSIONS Empowerment-based exercise programs may be particularly motivating for older adults by creating a more meaningful physical activity experience for them
