Abstract :
Introduction: The purpose of this study is to determine the effective of 8 weeks of proprioceptive neuromuscular facilitation training on agility and explosive power among female students in department of physical education and sports sciences in Islamic Azad University, Ali Abad Katoul branch. Methodology: Forty one participants selected for this study. The subjects were randomized in two groups included experimental group (N=21) and control group (N=20). Experimental group performed for 8 weeks, 3 times per week and at least 2 minutes PNF stretching protocol per session after warm up. The control group didn’t participate in PNF protocol. The subjects measured in before and after sessions. Results: The results of the study showed that there was a significant difference between the mean explosive power of the experimental group in pre and posttest, while there was no significant difference between the mean agility (p ≤ 0.05Conclusion: Results of the study recommended that 8 weeks of training that facilitates deep neuromuscular receptors by stretching-releasing the hamstring muscle method can increase the explosive power, so use this method to athletes who successfully perform their skills to power functions and need an explosion, it is recommended.
