    Abstract

    The aim of this investigation was to determine the differences in peak power, peak vertical ground reaction forces, and rate of force development (RFD) during variations of the power clean. Elite rugby league players (n = 16; age 22 6 1.58 years; height 182.25 6 2.81 cm; body mass 98.65 6 7.52 kg) performed 1 set of 3 repetitions of the power clean, hang power clean, midthigh power clean, or midthigh clean pull, using 60% of 1 repetition maximum power clean, in a randomized order, while standing on a force platform. One-way analysis of variance with Bonferroni post hoc analysis revealed a significantly (p,0.001) greater peak power output during the midthigh power clean (3,565.7 6 410.6 W) and the midthigh clean pull (3,686.8 6 386.5 W) compared with both the power clean (2,591.2 6 645.5 W) and the hang power clean (3,183.6 6 309.1 W), along with a significantly (p , 0.001) greater peak Fz during the midthigh power clean (2,813.8 6 200.5 N) and the midthigh clean pull (2,901.3 6 226.1 N) compared with both the power clean (2,264.1 6 199.6 N) and the hang power clean (2,479.3 6 267.6 N). The midthigh power clean (15,049.8 6 4,415.7 N.s21) and the midthigh clean pull (15,623.6 6 3,114.4 N.s21) also demonstrated significantly (p , 0.001) greater instantaneous RFD when compared with both the power clean (8,657.9 6 2,746.6 N.s21) and the hang power clean (10,314.4 6 4,238.2 N.s21). From the findings of this study, when training to maximize power, Fz, and RFD, the midthigh power clean and midthigh clean pull appear to be the most advantageous variations of the power clean to perform.
