초록

본 연구의 목적은 정적 스쿼트 동작 시 발란스 보드와 전신 진동자극기 적용이 신체 근육의 근활성도 변화에 어떠한 영향을 미치는지 검증하는 것이었다. 본 연구의 대상자는 20대 남성 20명을 대상으로 실시하였고(연령, 21.90±0.36 세; 신장, 174.30±1.09 cm; 체중, 66.50±1.00 kg; 신체질량지수, 21.90±0.31 kg/㎡), 3가지의 기본 정적 스쿼트 동작, 발란스 보드를 적용한 정적 스쿼트 동작 및 전신 진동자극기를 적용한 정적 스쿼트 동작을 수행하였으며, 표면전극을 부착한 부위는 신체 근육의 우측 복직근, 내복사근, 외복사근, 대퇴직근, 외측광근 및 내측광근으로 설정하였다. 실험을 통해 획득된 본 연구의 결과는 다음과 같다. 복직근, 내복사근 및 외복사근의 근활성도는 발란스 보드와 전신 진동자극기를 적용한 정적 스쿼트 동작 시 통계적으로 높게 나타났고(p=.001, p=.004, p=.000), 대퇴직근, 외측광근 및 내측광근의 근활성도는 전신 진동자극기를 적용한 정적 스쿼트 동작에서 통계적으로 가장 높게 나타났다(p=.000). 본 연구의 결과는 향후 정적 스쿼트 훈련 적용 시 효과적인 신체 근육을 강화시키기 위한 프로그램의 기초 자료가 될 것으로 기대된다.

The purpose of this study was to investigate the effects of balance board and whole-body vibration stimulator application on body muscle activities during static squat motion. Twenty adult males(age, 21.90±0.36 years; height, 174.30±1.09 cm; body mass, 66.50±1.00 kg; and BMI, 21.90±0.31 kg/㎡) were participated in this study as subjects. Three types' static squat motions were performed(basic static squat motion, BSSM; static squat motion with balance board, SSBB; static squat motion with whole-body vibration stimulator, SSVS). We measured the right side's body muscle activities of the rectus abdominis(RA), internal oblique(IO), external oblique(EO), rectus femoris(RF), vastus lateralis(VL), and vastus medialis(VM). The research findings were as follows. There was a significant higher RA, IO, and EO muscle activity of SSBB and SSVS(p=.001, p=.004, p=.000). And RF, VL, and VM muscle activities were greatest during SSVS(p=.000). These findings are expected to serve as references for static squat motion applications in training programs for body muscle strengthening.
