Abstract

Background/Objectives

The purpose of this study is to propose the effective posture of bridge exercise by comparing and analyzing the muscle activity of the internal oblique abdominal, external oblique abdominal, rectus abdominal and transverses abdominals, when performing bridge exercise with visual blocking and varying the stance.

Method/Statistical analysis

Muscle activity was measured by EMG. the study conducted a study of 30 people who do not have neurological disorder such as fracture, damage to the muscle and ligament, etc. for past 6 months For the experimental group, the stance was set to 100%, 50% and 150% of the shoulder width, the muscle activation was measured total 6 exercises by dividing into visual blocking and the stance and all the measured values were analyzed using ANOVA repeated measurement.

Findings

In the results of this study, all the internal oblique abdominal, external oblique abdominal, rectus abdominal and transverses abdominals showed higher muscle activation during the bridge exercise with visual blocking and representing significant difference. When the bridge exercise was performed with the stance of 50% shoulder width, the muscle activation was the highest and the difference by muscle according to the breadth of foot was varied.

Improvements/Applications

In conclusion, it is deemed that the bridge exercise with visual blocking and narrow foot width will be the more effective posture to improve the muscle activation and to stabilize the body.
