Abstract
[Purpose] In this study, hypothesizing that balance ability is related to trunk muscle strength, we conducted balance exercises for the trunk muscles, seeking to improve balance ability which is a risk factor of falls, and investigated their effects. [Method] Healthy young subjects performed balance exercises for the trunk muscles, two times a week for 12 weeks, and we investigated the exercise effect. The evaluated items were static and dynamic balance, muscle strength and flexibility. We used a Biodex to evaluate trunk muscle strength, and a Balance Master to evaluate mCTSIB and LOS. We also used performance tests to assess the overall change. [Result] The effect of ES was large on static balance (EOF.SI), dynamic balance (TUG), and trunk muscle strength, confirming the efficacy of the balance exercise. [Conclusion] The results demonstrate the relationship between trunk muscle strength and balance.
