The Effect of Different Warm-up Protocols on young Soccer Players' Explosive Power

Objective: To investigating the effect of different Warm-up Protocols on young Soccer Players' Explosive Power. Methods: Twenty male soccer players (17.4 0.685 years) volunteered to participate in this study. The participants were randomly selected, and in order to remove the effects of transmission and to observe the sequence of warm-up methods, they were cross-matched randomly e.g. 20 players in four categories; that is, 5 players in each category. The participants in each category experienced the 4 warm-up ways in four consecutive so that at the end 20 players performed each method of warm-up. Warm-up methods: 1. Static warm-up; 2. Dynamic warm-up plus 2 min active rest; 3. Dynamic warm-up plus 5 min passive rest and finally Dynamic warm-up plus 15 min passive rest. Participants in each category performed different warm-up methods which had been designed based on scientific and research-based sources in 48 hours intervals After performing each warm-up method, they were given a Long Jump. Results: Based on the results of analysis of variance between the effect of different warm-up methods on Explosive Power participants, significant difference was observed (p?0/05) so that Dynamic warm-up plus 5 min passive rest was more effective in Explosive Power performance than other methods(p?0/05). Discussion: The results of this study are in line with those of Roger (2008) and Faigenbaum et al (2006) who indicated in their studies that Dynamic or mixed method of warm-up are more effective than static ones. Conclusion: Therefore, with regard to the results of the study presented here and also the nature of football enjoying explosive power than the air blows, it is recommended that these types of protocols during warm-up program be employed.
