Effect of high versus low-velocity resistance training on muscular fitness and functional performance in older men
This study investigated the effect of a 10-week power training ( PT ) program versus traditional resistance training ( TRT ) on functional performance , and muscular power and strength in older men . Twenty inactive volunteers ( 60–76 years old ) were r and omly assigned to a PT group ( three 8–10 repetition sets performed as fast a possible at 60 % of 1-RM ) or a TRT group ( three 8–10 repetition sets with 2–3 s contractions at 60 % of 1-RM ) . Both groups exercised 2 days/week with the same work output . Outcomes were measured with the Rikli and Jones functional fitness test and a bench and leg press test of maximal power and strength ( 1-RM ) . Significant differences between and within groups were analyzed using a two-way analysis of variance ( ANOVA ) . At 10 weeks there was a significantly ( P < 0.05 ) greater improvement in measures of functional performance in the PT group . Arm curling improved by 50 versus 3 % and a 30 s chair-st and improved by 43 versus 6 % in the PT and TRT groups , respectively . There was also a significantly greater improvement in muscular power ( P < 0.05 ) in the PT group . The bench press improved by 37 versus 13 % , and the leg press by 31 and 8 % in the PT and TRT groups , respectively . There was no significant difference between groups in improved muscular strength . It appears that in older men there may be a significantly greater improvement in functional performance and muscular power with PT versus low velocity resistance training
