The purpose of this study was to compare the effects of combined free-weight and elastic training with cluster sets (CFEC) on peak power during clean pull (CP) exercises on youth weightlifters. Sixteen male and female elite junior weightlifters volunteered to participate in this study. The participants were randomly assigned into two groups (control and CFEC) of eight participants (four males and four females) using match pairs of relative CP strength. An undulatory periodized plan with 85-93% CP strength was employed for both groups. Both groups were required to perform a CP exercise with similar intensity. While the control group performed a 100% of traditional free-weight training, CFEC employed combined 90% free-weight and 10% elastic training with a 40-s rest between repetitions. Peak power (PP), relative peak power (RPP), peak force (PF), relative peak force (RPF), and peak velocity (PV) were assessed by a ballistic measurement system before and after 6-week of training. The Shapiro-Wilk test indicated that all dependent variables were normally distributed. Moreover, two independent t-tests were performed and confirmed that there were no statistical differences between the control and CFEC groups for all dependent variables at pre-test. ANCOVA was used to analyze dependent variables using pre-test values as covariates. The results showed the participants in CFEC significantly improved PP and RPP when compared to the control group at post-test (p<0.05). However, the results found no statistical differences in PF, RPF, or PV between the two groups. Our results indicated that CFEC is an effective training program for improving PP and RPP with minimal injury risks in junior weightlifters. [ABSTRACT FROM AUTHOR] |
