초록/요약
The aim of this study was to compare the difference in muscle activity with and without alignment and with the radial stabilisation method during the clamshell movement. 14 adult women in their 30s with Pilates experience were recruited for the study. The subjects performed the clamshell movement under three conditions using a simple random sampling method. gluteus medius(Gm), transversus abdominis(TrA), multifidus(MF), quadratus lumborum(QL) was measured using surface electromyography, normalized based on maximum volume isometric contraction(MVIC) and comparatively analyzed by %MVIC. The data were processed by one-way repeated ANOVA and Tukey’s W post hoc test. It was found that there was a difference in muscle activity between NC, PC, and ABC groups (p<.05). As a result of the study, the muscle activity of the gluteus medius, transversus abdominis and multifidus was highest among the three conditions in the active alignment and breathing exercise method. Among the three conditions, quadratus lumborum muscle activity was highest in the passive alignment exercise method and lowest in the active alignment and breathing exercise method. Based on the above results, it can be assumed that the exercise method with active alignment and breathing during the clamshell movement is the most effective. For selective strengthening of the gluteus medius, activation of the stabilising muscles must be achieved through pre-movement alignment. In conclusion, stabilization is achieved through pre-movement alignment and it is recommended that the activation of the stabilising muscles is preceded by Pilates breathing as a method of active control.
