Purpose: The purpose of this study is to compare and analyze the effects on brain function, muscle activity, and balance ability after applying acute training of VR, VRT, and TE.
Method:　The subjects of the study were healthy male adults, who were fully informed about the purpose and method of this study and voluntarily expressed their intention to participate (N=20). The same subjects were applied for each training. The subjects were trained for 60 minutes each time at 1 week intervals. Measurement variables were brain function (fp1, fp2, T4, T5, pZ), muscle activity and balance ability (static balance and dynamic balance). All statistics were analyzed by SPSS version 25.0. A one-way repeated ANOVA was performed to confirm the difference in muscle activity during exercise according to the type of training, and the Bonferroni method was used for prost-hoc analysis. On the other hand, a two-way repeated ANOVA was conducted to verify the difference between EEG before and after training application. A paired t-test was performed to confirm the difference between before and after the applied exercise method. All statistical significance levels were set at p<.05.
Results: The results of this study are as follows. 1) VR and VRT showed statistically significant changes between times and, according to post-hoc test, VR and VRT showed a positive effect compared to TE. 2) The muscle activity of the lower extremities showed statistically significant changes in the right and left tibialis anterior, biceps femoris and gastrocnemius in TE. 3) The balance ability in both static and dynamic balance was not significantly different.
Conclusion: In summary, the findings in this study confirm that VT and VTR have a positive effect on brain function. It can be recommended for new training.
