Effects Of Hip Thrust And Resistance Training On Shuttle Run, Hand Grip Strength And Countermovement Jump In Colombian Elite Male Volleyball Players

Abstract

PURPOSE: This study aimed to determine whether a hip thrust and resistance training could improve performance on shuttle run, hand grip strength and countermovement jump in elite volleyball athletes. METHODS: eleven elite male volleyball players (23,09 ± 2,87 years), body weight (84.91 ± 10.15 kg), average weight lean muscle (40,18 ± 3.07%), body fat (18.16 ± 5.45%) completed 2 training sessions per weeks, which included hip thrust exercise and upper resistance training. Over the 10 week season, the athletes performed 3-4 sets of 6 -10 repetitions for resistance exercises during each training session. All sessions were supervised by one of the investigators as well as by the Colombian team coach. Shuttle run, hand grip strength and countermovement jump were assessed before and after the 10 week training program. A total of 12 variables was analyzed through CMJ: (peak flight time (PFT), peak contact time (PCT), Peak eccentric duration (PDE), peak concentric duration (PDC), Peak eccentric work (PWE), Peak Concentric work (PWC), Peak jump height (PMH), Peak maximum velocity (PMV), Peak maximum power (PMP), Peak maximum force (PMF), Peak rate of force development (PRFD) and Peak time to maximum force (PTFM) were simultaneously quantified with the Gyko inertial sensor system (Microgate, Bolzano, Italy). RESULTS: Non parametric data were analysed by Wilcoxon and Spearman test. Significant correlations (r) were found next to the p value and the effect size (ES) of shuttle run, hand grip strength and those of countermovement jump respectively. Shuttle run (SR, p=0,000, r= 0,96, ES=0,23), Right hand grip strength (HGS R, p=0,000, r= 0,90, ES=0,18), Left hand grip strength (HGS L, p=0,000, r= 0,91, ES=0,22). CMJ performance variables: Peak concentric duration (PDC, p=0,000, r= 0,68, ES=0,44), Peak Jump Height (PMH, p=2,0, r= 0,88, ES=1,1), Peak maximum velocity (PMV, p=0,000 r= 0,63, ES=0,61). CONCLUSIONS: The findings suggest that elite male volleyball players can improve speed, agility, hand grip strength and vertical jump performance during the pre competition season by implementing a well designed training program that includes both hip thrust and resistance training exercises.
