Abstract

In this study, the effects of suspension training according to the types of ground. Fourteen healthy male college students measured for the characteristics of core muscle activity in suspension training on two different types of grounds, normal flat and unstable ground using a gym ball. EMG (Electromyography) was exploited to measure the activity of the core muscles according to the types of the ground. Muscle activity of the abdominal muscles, external oblique muscles, internal oblique muscles, and lower lumbar standing muscles was measured. The variables in analyses were measured by the means of % MVC method to standardize the EMG signal according to the ground type for each core muscle. In order to verify the differences in core muscles according to the type of ground the paired t-tests were performed at the significance level of 0.05 (p<.05). As a result of measuring the activity of the core muscles according to the various types of grounds, the difference between muscle characteristics obtained in two different grounds did not appear to be statistically significant. However, the result is an important clue to reconsider the notion that the training effect on the unstable ground is generally superior to the effect on the stable ground in the core muscle training. The type of ground in the core muscle training has been found not to significantly affect the muscle activation according to the results of this study. Regardless of the type of exercise program, hence, the difference in muscle activation will not be insignificant even with the standardized program strengthening core muscles.

본 연구는 지면의 유형에 따른 서스펜션 트레이닝의 효과를 분석하기 위해 14명의 건강한 남자 대학생을 대상으로 2종류의 다른 지면 편평한 지면, 짐볼을 이용한 불안정한 지면에 따른 서스펜션 트레이닝의 주목적인 코어 근육의 활성 특성을 연구하였다. 지면의 유형에 따른 코어 근육의 활성도를 측정하기 위해 EMG(Electromyography)를 활용하였고 측정부위는 복직근, 외복사근, 내복사근, 하부요추 기립근의 근활성도를 측정하였다. 측정변인은 각각의 코어 근육 별로 지면의 유형에 따라 근전도 신호를 표준화하기 위해 %MVC방법으로 측정하였다. 지면의 유형에 따른 코어 근육의 차이를 검증하기 위해 paired t-test를 실시하였으며 유의수준은 p<. 05로 설정하였다. 다양한 유형의 지면에 따른 코어 근육의 활성도에 관한 특성을 측정한 결과 두 지면 사이의 근육 별, 지면 별 차이점은 통계적으로 유의하게 나타나지 않았다. 하지만 이는 코어 근육의 트레이닝의 적용 시 반드시 불안정한 형태의 지면에서의 트레이닝 효과가 안정된 지면에서의 효과보다 우월하다는 통념을 다시 한 번 생각하게 하는 중요한 결과라 사료된다. 본 연구의 의미는 불안정한 지면이나 안정된 지면이 코어 근육 활성화에 큰 영향을 미치지 않으므로 어떠한 운동프로그램이던지 정규화된 코어근육 강화프로그램을 실시해도 근육의 활성화에 차이가 없음을 의미한다.
