초록

본 연구의 목적은 무릎 푸시업 플러스 동작 시 슬링과 진동기 적용이 체간 근육의 근활성도 변화에 미치는 영향에 대해 알아보는 것이었다. 본 연구의 대상자는 신체 건강한 20대 남성 10명을 대상으로 실시하였고(연령, 23.00±0.45 세; 신장, 176.60±1.64 cm; 체중, 67.50±1.22 kg; 신체질량지수, 21.65±0.34 kg/㎡), 3가지의 기본 무릎 푸시업 플러스 동작, 슬링을 적용한 무릎 푸시업 플러스 동작, 및 진동기를 적용한 무릎 푸시업 플러스 동작을 수행하였으며, 표면전극 부착 부위는 체간 근육의 오른쪽 상부 승모근, 대흉근, 전거근, 복직근, 및 외복사근으로 설정하였다. 본 연구의 결과는 다음과 같다. 승모근, 대흉근, 전거근, 복직근, 및 외복사근의 근활성도는 진동기를 적용한 무릎 푸시업 플러스 동작 시 통계적으로 가장 높게 나타났다(p<.001). 따라서 본 연구의 결과는 향후 무릎 푸시업 플러스 동작 적용 시 효과적인 체간 근육을 강화시키기 위한 트레이닝 프로그램의 기초자료가 될 것으로 기대된다.

The purpose of this study was to investigate the effects of sling and vibrator application of knee push-up plus motion on trunk muscle activities. Ten healthy adult males(age, 23.00±0.45 years; height, 176.60±1.64 cm; body mass, 67.50±1.22 kg; and BMI, 21.65±0.34 kg/㎡) were participated in this study as subjects. Three types' knee push-up plus motions were performed(basic knee push-up plus motion, BKPP; knee push-up plus motion with sling, KPPS; knee push-up plus motion with vibration, KPPV). We measured the right side's trunk muscle activities of the upper trapezius(UT), pectoralis major(PM), serratus anterior(SA), rectus abdominis(RA), and external oblique(EO). The research findings were as follows. UT, PM, SA, RA, and EO muscle activities were greatest during KPPV(p<.001). These results are expected to serve as reference materials for knee push-up plus motion applications in training programs for trunk muscle strengthening.
