전신 기울임 운동시 축 회전 유무에 따른 체간근 활성도 변화

다국어 초록 (Multilingual Abstract)

Determining of the exercise intensity is very important in terms of induction of low fatigue during exercise. Little information is available on the contraction level of the trunk muscles during whole body tilts with and without axial rotation. This study was to investigate the difference muscle activation level according to axial rotation. Twenty subjects were participated. The muscle activities of the five trunk muscles were bilaterally measured at eight axial rotation angles with 12 tilt angles along 15° intervals. The results showed that tilt with 45° axial rotation was more balanced in the same tilt angle and was maintained approximately level of 40% MVC at over 60° tilt angle with respect to co-contraction of abdominal and back muscle. Lumbar stabilization exercise using whole body tilts would be more effective with axial rotation than without axial rotation in terms of muscle co-contraction.
