초록

Background: Muscle activities of gluteus maximus (GM) and hamstring (HAM) have im-portant roles in the stability and mobility of the hip joint during various functional activities including bridge and prone hip extension exercises.
Objects: The purpose of this study is to investigate muscle activities of GM, multifidus (MF) and HAM during three different bridge exercises in healthy individuals.
Methods: Twenty healthy subjects were participated. Electromyography device was used to measure muscle activities of GM, MF and HAM. Each subject was asked to perform three dif-ferent bridge exercises with hip abduction (0°, 15°, 30°) in random order. One-way repeated measures analysis of the variance and a Bonferroni post hoc test were used. Statistical signifi-cance was set at α = 0.01.
Results: The muscle activity of GM was significantly different among three conditions (hip abduction 0°, 15°, 30°) (adjusted p-value [Padj] < 0.01). The muscle activity of GM was sig-nificantly greater during bridge exercise with hip abduction 30° compared to 0° and 15° (Padj < 0.01). There was no significant difference in the muscle activity of MF and HAM muscle (Padj > 0.01). The ratio of muscle activity (ratio = GM/HAM) during bridge exercise with hip abduction 30° was significant greater compared to the hip abduction angles 0° and 15° (Padj < 0.01).
Conclusion: Bridge exercise with hip abduction 30° can be recommended to selectively facili-tate the muscle activity of GM and improve the ratio of muscle activity between GM and HAM.
