| Abstract |
Purpose: To examine the effects of a low-volume repeated-power-ability (RPA) training program on repeated-sprint and change-of-direction (COD) ability and functional jumping performance. Methods: Twenty-two male elite young basketball players (age 16.2 +/- 1.2 y, height 190.0 +/- 10.0 cm, body mass 82.9 +/- 10.1 kg) were randomly assigned either to an RPA-training group (n = 11) or a control group (n = 11). RPA training consisted of leg-press exercise, twice a week for 6 wk, of 1 or 2 blocks of 5 sets x 5 repetitions with 20 s of passive recovery between sets and 3 min between blocks with the load that maximized power output. Before and after training, performance was assessed by a repeated-sprint-ability (RSA) test, a repeated-COD-ability test, a hop for distance, and a drop jump followed by tests of a double unilateral hop with the right and left legs. Results: Within-group and between-groups differences showed substantial improvements in slowest (RSA(s)) and mean time (RSA(m)) on RSA; best, slowest and mean time on repeated-COD ability; and unilateral right and left hop in the RPA group in comparison with control. While best time on RSA showed no improvement in any group, there was a large relationship (r = .68, 90% CI .43;.84) between the relative decrement in RSA(m) and RSA(s), suggesting better sprint maintenance with RPA training. The relative improvements in best and mean repeated-COD ability were very largely correlated (r = .89, 90% CI. 77;.94). Conclusions: Six weeks of low-volume (4-14 min/wk) RPA training improved several physical-fitness tests in basketball players. |
