Abstract

Background and Aims: plyometric exercises are one of the exercises that increase the speed of conduction of nerve flow and the speed of muscle contraction. The purpose of this study was to investigate the effect of plyometric exercises on blood lactate levels and some indicators of aerobic and anaerobic fitness in female taekwondo athletes

Method: This study is semi-experimental and its statistical population is female taekwondo athletes from Kermanshah city, among whom 20 athletes were available subjects with an age range of 16-35 years and a sports experience of at least 8 years selected and were randomly divided into two training (n=10) and control (n=10)groups . The training protocol included 6 weeks of plyometric exercises, three sessions per week and each session was 55 minutes. The data were analyzed using the dependent t-test and ANOVA by SPSS24 software at a significance level of p≤0.05.

Results: The results of depended t-test showed that the average values of speed (p=0.032), aerobic power (p=0.045), anaerobic power (p=0.001), blood lactate (p=0.001) in the training group had a significant improvement . Also, the results of ANOVA showed that the mean values of speed (p=0.003) had a significant difference but the difference of agility (p=0.145), aerobic power (p=0.15), anaerobic power (p=0.07) and blood lactate level (p=0.099) and agility (p=0.118) were not significant.

Conclusion: According to the results of this study, this type of exercise can be suggested as a type of complementary exercise to improve the physical and movement performance of taekwondo athletes.
