Conventional Jump Warm-Up with and Without Jumping Rope on Jumping Ability Among Volleyball Players

Volleyball is a sport that required the athlete to have a powerful lower limb especially during jumping. The purpose of this study was to investigate the acute effect of warm up with jumping rope versus without jumping rope on leg power among university volleyball players. Sixteen (n = 16) university volleyball athletes range age between 18 to 25 years old. The randomized cross-over design was employed as each of the subject was undergone the no warm-up (NWU), conventional jump warm up with jumping rope (WJR) and warm up without jumping rope (WoJR) that was assessed by Vertical Jump (VJ) test and Standing Broad Jump (SBJ) test with one week of recovery period between the tests to avoid the carry over effect. The data has been analyzed by Statistical Package of Social Science SPSS 22.0. One-way Repeated Measure Analysis of Variance (ANOVA) was employed to observe the effect of NWU, WoJR and WJR on VJ and SBJ among volleyball athletes. The results shown that there is no significant difference between WoJR and WJR on VJ (p = .497), and there was also no significant difference between WoJR and WJR on SBJ (p = .231). However, there was a significant difference measured between of NWU and WoJR on VJ (p = .020).
