تأثیر دو شدت ‮‭PAP‬ با زمان های استراحتی متفاوت بر عملکرد و کوفتگی عضلانی مردان تکواندوکار

Introduction: Through analyzing taekwondo Competition it can be understood that the factors such as speed, agility and power have an important role in taekwondo and without them it is impossible to be a successful taekwondo athlete. PAP is one of the methods that is usually used to increase nerve-muscular activity after intense practice. Considering the important role of PAP, the present study aimed to investigate the effect of two intensity PAPs with different time period resting on performance and muscle soreness in taekwondo male athletes. Methodology: in order to do the aim of the study, in a quasi -experimental design study, based on the fat content and bodily performance, 27 homogeneous taekwondo athletes who their ages ranged between 18 to 28 were selected, and they were randomly assigned into three groups; 1) warming with three time repeated half-squats (IRM=70 ), 2) warming with three time repeated half-squats (IRM=90 ), 3) control group (general and special warming). During the research, first the participants of the three groups warmed themselves (generally and specially) 15-20 minutes. Then, the participants of the experimental groups did half-squats with predetermined intensity (i. e. 70 and 90). Then, they did the same work two time; one after 2 minutes resting and the other one after 4 minutes resting which was done after 48 hours. Then, after 24 hours their vertical jumping, performance (Ap-Doloya-Chagi), and muscle soreness were measured and analyzed using SHAPIROVIL, ANCOVA, and Bonferroni tests (p < .05). Results: The results of the descriptive statistics showed that there was a significant difference between the three groups vertical jumping and performance in both resting time (i. e. 2 minutes and 4 minutes resting), and both of two intensity PAPs could improve participants performance (p < .05). But, there was not a significant difference between the three groups muscle soreness in both resting times. Conclusion: PAP in both 70 and 90 intensity can improve taekwondo athletes performance
