The Effect of 8 Weeks Virtual Reality Training on Static and Dynamic Balance and Performance in Male Athletes With Functional Ankle Instability

  Introduction: The purpose of this study is to investigate the effect of  8 weeks  virtual reality training on static and dynamic balance and performance of in male athletes with functional ankle instability Research Methodology: For this research, 30 volleyball, basketball, football and handball players ranged from 18 to 25 years were selected purposefully from Tehran province league male athletes based on inclusion and Exclusion criteria. Then Subjects were randomly divided into two groups included 15 subjects of virtual reality exercises and control group. After a 5 minute warm-up program, the static and dynamic balance and performance were measured by stork test, y balance test and side jump and triple jump test respectively. Then, training group completed a 8-week (24 sessions) exercise program. Finally, after completing the training protocol, a similar post-test with pre-test was done. To test and analyze datum, also analysis, paired t-test and ANCOVA statistical method was used. Results: Paired t-test and analysis of covariance showed that there was a significant difference in all variables in the post-test compared to the pre-test and also between the two groups  (05/0>p).The balance of subjects and their performance in the experimental group was improved Conclusion: 8 weeks of virtual reality training significantly improve balance and performance of male with functional ankle instability; therefore coaches and athletes can use this exercises to improve balance and performance in athletes with functional ankle instability.
