EFFECTS OF GLUTEUS MEDIUS STRENGTHENING EXERCISE ON ANKLE MUSCLE ACTIVATION AND DYNAMIC BALANCE IN HEALTHY ADULTS

다국어 초록 (Multilingual Abstract)

The aim of this study was to investigate the effect of the gluteus medius muscle strengthening exercise on the ankle muscle activity and dynamic balance in healthy adults. Participants were randomly assigned to 15 subjects in the experimental group and 16 subjects in the control group. The experimental group performed the gluteus medius muscle strengthening exercise, and the control group had no intervention. The study period was conducted 3 times a week for 6 weeks. Surface EMG was used to measure changes in ankle muscle activity, and Y-balance test (YBT) and functional reach test (FRT) were used to measure dynamic balance. The results showed significant decrease in the ankle muscle activity of the peroneus longus in the experimental group compared to the control group (p<0.05). In addition, there were significant differences in ankle muscle activity of the peroneus longus between the two groups (p<0.05). In dynamic balance analysis, the experimental group showed significant improvements in the FRT and YBT values compared to the control group (p<0.05). Also, there was significant difference in the FRT values between the two groups (p<0.05), but there was no significant difference in the YBT value between the two groups. In conclusion, strengthening the gluteus medius muscle for 6 weeks had an effect on the decrease in the activity of the peroneus longus muscle and was effective in improving the dynamic balance. This study has clinical significance in that it suggested a variable that the gluteus medius muscle and peroneus longus muscle should be considered together to improve balance. In addition, further study is needed to perform the gluteus medius muscle strengthening exercise in subjects with gluteus medius weakness or ankle instability.
