The effect of three methods of warm-up on the anaerobic power, agility, speed, flexibility and fatigue index of elite female volleyball players

The main purpose of this study was to evaluate the effects of warm-up on the anaerobic power, agility, speed, flexibility and fatigue index elite female volleyball players. To this end, 20 of the volleyball players aged 18 to 30 years and at least 5 years of experience in the sport voluntarily participated in this study. Each of the warm-up method consists of three sessions per week for a week and then test. Warm-up exercise includes warm-up routine, vibration, and a combination of both. The aerobic power, agility, speed, flexibility and fatigue index were measured after each training session. For data analysis of repeated measures and the significance of the results of the Bonferroni post-test were used. Base on the results after three warm-up exercise, no significant difference was observed between aerobic power, agility, and speed. No significant difference was observed in the flexibility and fatigue index. In general, it can be concluded that the combination of warm-up with vibration can improve aerobic power, agility and speed will be. Hence, it can be offered as a new method of warm-up in the different sports to athletes and coaches. Therefore, combined warm-up with vibration increases blood flow to active muscles and nerve receptors and increases the speed of nerve impulses
