Comparison of a combined strength and handball-specific training vs. Isolated strength training in handball players studying physical education
MetadataShow full item record
Objectives The purpose of this study was to compare the effect of combined resistance training including handball-specific drill (CRT) with resistance training excluding handball-specific drill training (NSDT). Materials and methods Twenty-two male handball players who studied physical education were randomly assigned to two groups: CRT (combined resistance training with sport-specific drill; n=12) and NSDT (resistance training without any sport-specific drill training; n=10). Over a 10-week period during the competitive season, the players performed a specific training program twice per week, which replaced their normal team handball training. The CRT regimen consisted of a combined (associated) resistance training and handball-specific drill, whereas the NSDT program consisted of a resistance training without handball-specific drill (dissociated). Pre- and post-test measures included squat jump and countermovement jumps, bench press, back half squats, throwing velocity during a 3-step jump throw, and a jump shot, repeated-sprint ability (six 2�15-m shuttle sprints) (RSA), medicine ball throw and anthropometric measurements. Results In both groups, significant intervention effects (d?1.0) were seen for all sprint (3/3), throwing (3/3) and jump (2/2) measures. Regarding maximal strength parameters, an effect size lower than 0.5 was only detected in the NSDT group for half back squats (d=0.48). The largest effects were observed in the NSDT group for squat jump (d=6.20) and medicine ball throw (d=6.07). Interaction effects (group � time) were found for 50% (5/10) of parameters. The greatest difference between groups regarding performance development over time was detected for jump shot (interaction effect: ?2;=0.748). In contrast, there was no difference in performance development in both groups over time for RSA best (interaction effect: ?2;=0.025). Conclusions The current findings suggest that during the competitive season, 10 weeks of CRT with only two training sessions per week improved numerous measures of athletic performance in handball students of physical education. Such conditioning should be highly recommended as part of the annual training program of handball players. - 2019 Georg Thieme Verlag KG, Stuttgart � New York.
