Purpose : The purpose of this study was to examine the correlation between static and dynamic balance according to the virtual reality-based squat and conventional squat exercise.
Method : Twenty four participants were randomly assigned to the virtual reality-based squat (VRS) group (n=12) or conventional squat (CS) group (n=12). The static balance (C90 area, C90 angle, trace length, sway average velocity) and dynamic balance (forward, rearward, leftward, rightward) were measured using a force plate by BT4. The VRS group used the virtual reality system during 4 weeks, while the CS group underwent classical squat training. The collected data was analyzed using the paired t-test for static and dynamic balance comparisons before and after exercise in both groups and Pearson's test for the correlation between static and dynamic balance according to the measured time. The significance level was set to 0.05
Result : There was no significant correlation between group and static and dynamic balance related variables(p＞.05). There was a significant correlation between measurement time and static and dynamic balance related variables(p＜.05). According to the measurement time, the static balance parameter C90 area in the VRS group after exercise was significantly decreased(p＜.05). The values of forward, leftward and rightward in the VRS group were significantly increased after exercise(p＜.05).
Conclusion : It is suggested that 20 normal healthy adult men and women who have normal balance ability can improve their ability to control their posture by improving the balance ability when applying virtual reality-based squat exercise.
