Finally , muscle power testing was found to be safe in older people with a broad range of health and functional states
Background Muscle power has been proposed to be the primary therapeutic target for resistance training interventions aim ed at enhancing physical function in older adults .
However , no recommendations exist on ideal testing protocol s to assess muscle power in older adults , and the safety of this procedure has not been adequately evaluated in the literature .
Methods A systematic review was conducted to identify studies evaluating muscle power exerted by older people in resistance exercises through May 2017 .
Effect of Rest Interval Length on Repeated 1 Repetition Maximum Back Squats
To examine the effects of different rest intervals on the repeatability of 1 repetition maximum ( 1RM ) efforts in the free-weight back squat exercise , 17 weight-trained men served as subjects ( mean age 22.0 years ) . One repetition maximum was tested on each of the first 2 days of testing to establish a stable baseline ( 1RM = 184.9 kg ) . Each of the next 3 sessions involved performing 2 1RM back squats , with the rest interval between attempted lifts being either 1 , 3 , or 5 minutes , assigned in a counterbalanced fashion . For the 1-minute rest interval , 13 of 17 subjects successfully completed the second lift ; for the 3-minute rest interval , 16 of 17 were successful ; and for the 5-minute rest interval , 15 of 17 were successful . Cochran Q analysis determined no significant difference ( p > 0.05 ) in the ability to repeat a successful maximal-effort back squat when different rest intervals were used . These findings are consistent with the literature for the bench-press exercise and indicate that 1-minute rest intervals are sufficient for recovery between attempted lifts during 1RM testing or training for the free-weight back squat when involving lifters of this caliber
