Comparison of Gluteus Maximus, Hamstring and Multifidus Muscle Activities During Bridge Exercises According to Three Different Hip Abduction Angles

Abstract

Background: Muscle activities of gluteus maximus (GM) and hamstring (HAM) have important 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 different 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 significance 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 significantly 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 facilitate the muscle activity of GM and improve the ratio of muscle activity between GM and HAM.

Effects of Band-Resisted Abduction on Muscle Activity between the Barbell Hip Thrust and Barbell Glute Bridge

“…Furthermore, stance width was standardized to shoulder span to create an approximate abduction angle of 30°, and maximum abduction effort was assumed. Future research should measure hip abduction angles and forces, as 30° of hip abduction elicits significantly greater muscle activity of the GMax than lesser abduction angles (10,11,25). This would help reduce hip abduction angle discrepancies in both band-resisted and non-banded conditions, and distinguish which condition produces greater force.…”

Comparisons of Gluteus Maximus and Hamstring Muscle Activities according to Three Different Sling Locations during Bridge Exercise with Sling in Supine Position

“…16,17 Exercise with Ankle Sling, BEAS), 슬링이 장딴지에 위치하고 교각 운동 을 수행하는 자세(Bridge Exercise with Calf Sling, BECS) 그리고 슬링이 무릎 관절에 위치하고 교각 운동을 수행하는 자세(Bridge Exercise with Knee Sling, BEKS) 중에서 큰볼기근 근활성도가 가장 높고 넓적 다리뒤근의 근활성도가 가장 낮은 운동 방법을 찾고자 한다. 또한 세 가지 다른 위치의 슬링을 이용한 교각 운동 자세에서 큰볼기근과 넓 적다리뒤근의 근활성도 비율이 가장 효과적인 운동을 찾고자 한다.…”
