Abstract

This study examined the effects of 8-week combined plyometric exercise and high intensity running training (combined training) on the performance fitness in male U17 handball players. Participants were randomly divided between experimental (E; n = 15; age: 16.5 ± 0.4 years) and control (C; n = 13; age: 16.7 ± 0.3 years) groups. The E group performed combined training (4 workshops) twice a week over 8 weeks. Each session lasted approximately 35 min. The C maintained regular in-season training. Before and after the combined training, both groups underwent repeated sprint ability (RSA), sprint performance (5m, 10m, 20m and 30m), change of direction test (Modified change-of-direction T-test (T-half)), vertical jump (squat jump (SJ), counter-movement jump (CMJ), counter-movement jump with aimed arms (CMJA)), horizontal jump (five-jump test (5JT)), strength (1-RM half squat), and 20-meter shuttle run. Group x time interaction showed significant increases on sprint performance (p < 0.01, 8.6%; p < 0.001, 7.3%; p < 0.05, 6.9%; and p < 0.01, 8.9% over distances of 5m, 10m, 20m and 30m respectively) in E relative to C. The T-half also showed significant gains for E (p < 0.05, 6.8%), as did vertical jumping (p < 0.01, 32.7%; p < 0.001, 32.6% and p < 0.001, 23% for SJ, CMJ and CMJA respectively) and horizontal jumping (p < 0.05, 13.3%) compared to C. Moreover, there were significant improvements of RSA and 20 m shuttle run in E compared to C. However, there were no significant differences in 1-RM half squat between groups. We conclude that the allocation of short periods of a combined training is effective in enhancing performance fitness and thus can be commended to male U17 Handball participants as a potentially useful component of their training.
