Abstract :
Background& Purpose: Present study was aimed to investigate Effects of Dynamic Warm-up With and Without a Weighted Vest on jump and maximal power performance of lower limb in male soccer players.Material and Methods: 15 young male soccer players voluntarily participated in this study. Warm up protocol included General Warm up (running at 70% of maximum heart rate) and Warm up using Weighted Vest was about 6% of body weight participants. The data was processed by using SPSS version 21 and dependent t-test and 2-way ANOVA for repeated measures and Bonferroni test. Results: Dynamic Warm-up without a Weighted Vest led to significant decrease in long jump record, jump Sargent index and maximal strength (p≤0.05). In contrast, Dynamic Warm-up with Weighted Vest resulted in a significant increase in long jump, jump Sargent and maximal strength (p≤0.05). Dynamic Warm-up with Weighted Vest led to significant increase in long jump performance in comparison of General Warm up (p≤0.05). There was no significant difference between the effects of two dynamic warm-ups in jump performance, Sargent and lower limb maximal strength (p≤0.05). Conclusion: The results showed an improvement in vertical jump performance with load 6% by weight vest during the warm-up protocol compared to the General Warm up. It seems that the use of this method of heating is more effective in developing power performance of young soccer players.
