Abstract
Background/Objectives: This study was conducted to compare and analyze the muscle activity of vastus lateralis, muscle vastus medialis, spinal erector muscles and gluteus maximus muscle using the EMG measuring device and suggest effective results of the bridge exercise when conducting the bridge exercise with various bridge postures using resistance of Thera-band on the stable support surface.
Method/Statistical Analysis:In order to examine the difference in the muscle activity of vastus lateralis, vastus medialis, erector spinae and gluteus maximus, a total of 3 exercises were conducted by each different posture; the normal bridge posture, the hip adduction bridge posture using the resistance of Thera-band and the hip abduction bridge posture using the resistance of Thera-band. The measured results of the experiment was analyzed by repeated measure analysis of variance
Findings: The results showed that muscle activity was all higher when conducting the bridge exercise using the resistance of Thera-band for vastus lateralis, vastus medialis, erector spinae and gluteus maximus, In the hip adduction bridge posture, vastus lateralis and vastus medialis showed significant difference, and in the hip abduction posture, gluteus maximus showed significant difference compared to the normal bridge posture.
Improvements/Applications: It is considered that the hip abduction bridge exercise and the hip adduction bridge exercise using the resistance of Thera-band can help stabilize the body.
