초록

The purpose of this study was to analyze the effects of core stabilizing exercises (three types of flank movements) on lumbar muscle activity to find adequate exercise time by understanding the relationships of time, intensity, and frequency of exercises. Twelve male participants in their 20s participated in this study. Participants did exercises on front side(20secs), right side(20secs), and left side(20secs) for a total of 60secs and repeated those exercises three times. In addition, participants repeated lumbar spine exercises for 4 minutes. In all of the front, left, and right side postures, there are significant mean differences(p<.05) and interaction effects(p<.05) of erector spinae muscle, rectus muscle, gluteus medius muscle, and rectus femoris for each group and each trial. In the left side posture, the strongest muscle activity was found in rectus muscle, and in the right side posture, the strongest muscle activity was found in erector spinae muscle. Findings showed that the strongest muscle activity in general was found at the time participants did three minutes exercises consisting of three sets of one minute exercises with three types of flank movements. Future studies need to examine not static (i.e., kinetic) flank movements for a better understanding of the effects of core stabilizing exercises on lumbar muscle activity, which contributes to the better quality of life.
