The research was quasi-experimental with a pretest-posttest design with a control group. Due to the availability of sample selection, the statistical population of the present study, including 24 taekwondo practitioners (with white, yellow and green belt), was selected, who are completely familiar with the basics of taekwondo, with family satisfaction and cardiovascular endurance tests and a relatively good level of sports. The experimental protocol consisted conducted 12 sessions of 30 minutes 3 days per week for 4-weeks and during this period they did not do any training, even recreationally. The MANOVA test was performed for data analysis. Before analysis of variance, the necessary assumptions such as the normality of the distribution of dependent variables, homogeneity of variance, variables of regression line slope homogeneity and regression slope were examined. Both groups maintained their regular taekwondo training, which was the same. The results showed a significant difference between the experimental and control groups (p≤0/05). Virtual reality exercises increase the perceptual- motor performance of all components have a significant effect on agility, endurance, strength, balance flexibility and perception of taekwondo practitioners compared to the control group (p≤0/05). Therefore, it is suggested to be used in the training program taekwondo athletes.
