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.
