Purpose: The purpose of this study was to investigate the effect of blood flow restriction bridge exercise on leg muscle thickness and balance. In addition, it is to promote blood flow restriction exercise as the basis for early prevention, diagnosis, and treatment of sarcopenia in clinical practice.
Methods: Twenty elderly women aged 65 years or older were selected to participate in this study. The subjects were divided into two groups of 10: one with blood flow restriction with bridge exercise (BFRG) and the other with bridge exercise alone (BG). As for the exercise method, the thickness of rectus femoris and vastus medialis and Berg balance scale were investigated by intervention for 30 minutes a day, 3 times a week, for a total of 6 weeks.
Results: There was significant difference in the thickness of the rectus femoris and vastus medial and within-group changes in the Berg balance scale (p <0.05) before and after the experiment in the BFRG and BG groups (p<0.05). There was a significant difference in change between the two groups (p <0.05).
Conclusion: There was a significant difference in the intragroup change of the Berg balance scale in the BFRG before and after the experiment, but there was no significant difference in the BG, and there was no significant difference in the change between the two groups.
