Kinetic comparisons during variations of the power clean

The aim of this investigation was todetermine the differences in peak power, peak vertical groundreaction forces, and rate of force development (RFD) duringvariations of the power clean. Elite rugby league players (n =16; age 22 6 1.58 years; height 182.25 6 2.81 cm; body mass98.65 6 7.52 kg) performed 1 set of 3 repetitions of the powerclean, hang power clean, midthigh power clean, or midthighclean pull, using 60% of 1 repetition maximum power clean, in arandomized order, while standing on a force platform. One-wayanalysis of variance with Bonferroni post hoc analysis revealeda significantly (p,0.001) greater peak power output during themidthigh power clean (3,565.7 6 410.6 W) and the midthighclean pull (3,686.8 6 386.5 W) compared with both thepower 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 6200.5 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) andthe hang power clean (2,479.3 6 267.6 N). The midthighpower clean (15,049.8 6 4,415.7 N.s21) and the midthighclean pull (15,623.6 6 3,114.4 N.s21) also demonstrated significantly(p , 0.001) greater instantaneous RFD when comparedwith 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). Fromthe findings of this study, when training to maximize power, Fz,and RFD, the midthigh power clean and midthigh clean pullappear to be the most advantageous variations of the powerclean to perform
