Comparison of Training Effects of Split-Style Olympic Lifts and Squat-Style Olympic Lifts on Performance in Collegiate Volleyball Players

Abstract

This study compared the training effects of split-style Olympic lifts (SP-L) with those of squat-style olympic lifts (SQ-L). In the study, the participants (n = 33 collegiate female volleyball players) were sorted on a random basis into the SP-L group (age = 15.80 ± 1.03 years; height = 164.50 ± 3.96 cm; body weight = 60.88 ± 8.26 kg), SQ-L group (age = 15.22 ± 1.2 years; height = 167.78 ± 3.53 cm, body weight = 62.02 ± 7.20 kg), and control group (CG; age = 15.14 ± 0.38 years; height = 165.29 ± 5.25 cm; body weight = 61.32 ± 5.89 kg). The groups performed split and squat snatch and clean and jerk twice a week for 6 weeks. Analysis of variance and magnitude-based inferences determined whether there was a significant difference in the measured variables among groups. In the groups, compared with the pretraining values, a significant and positive improvement was noted in posttraining leg stiffness and time to 5-m and 20-m sprint. However, for the time to 5-m sprint, the gains in the SP-L group were better (large/d = 1.79). In addition, an increase to spike jump and change of direction in the SP-L group alone was significant for the main effect of time (p < 0.05). The results of this study indicate that SP-L are more effective for spike jump, change of direction, and time to 5-m sprint. Although the results of the study provide insights regarding the beneficial effects of training with SP-L rather than SQ-L, consolidation of the study results with the results of future studies is warranted.
