title: No kinetic differences during variations of the power clean in inexperienced female collegiate athletes.
abstract: Previous research has identified that the second pull phase of the clean generates the greatest power output and that the midthigh variations of the power clean also result in the greatest force and power output in male athletes; however, no research has compared the kinetics of the variations of the power clean in women. The aim of this investigation was to identify any differences between variations of the clean, across a range of loads, in inexperienced female collegiate athletes. Sixteen healthy female collegiate athletes (age 19 ± 2.3 years; height 166.5 ± 3.22 cm; body mass 62.25 ± 4.52 kg; 1 repetition maximum [1RM] power clean 51.5 ± 2.65 kg) performed 3 repetitions of 3 variations (power clean, hang power clean, midthigh power clean) of the power clean at 60, 70, and 80% of their predetermined 1RM power clean, in a randomized and counterbalanced order. A 2-way analysis of variance (3 × 3; load × variation) revealed no significant differences (p > 0.05) in peak power, peak vertical force (Fz) or rate of force development (RFD) between loads or variations of the power clean. There appears to be no advantage in terms of peak power, Fz, or RFD between variations of the clean, in inexperienced female athletes, it is suggested, therefore, that inexperienced athletes intermittently perform different variations of the clean to ensure all round development and technical competence in each variation of the exercise.
