Abstract
[목적] 본 연구는 8주 간의 비대면 요가가 신체조성, 근활성도, 유연성, 균형감각이 미치는 영향을 살펴보는 것에 목적이 있다. [방법] 총 22명의 성인 남녀(남자 7명, 여자 15명)를 대상으로 8주 간 요가 트레이닝을 수행한 처치군(Treatment Group, TG, N=11), 운동을 수행하지 않은 통제군(Control Group, CG, N=11)으로 나누어 진행하였다. 8주 간 요가 트레이닝을 진행한 후 트레이닝 전·후의 신체조성, 체전굴 및 체후굴 동작 수행 시의 근활성도, 좌전굴 및 체후굴동작 수행 시의 유연성 및 제자리 한발 서기 동작 수행 시의 균형감각에 미치는 효과를 검증하였다. 처치군과 통제군의 차이점을 분석하기 위하여 독립 t-test를 시행하였고, 그룹과 시기 간의 상호작용 효과를 파악하기 위하여 반복이원분산분석을 실시하였다. 평균(M)과 표준편차(SD)를 산출하였고 유의수준은 p <.05이다. 통계학적 자료 분석은SPSS 25 version을 사용하였다. [결과] 첫째, 트레이닝 적용 전·후 신체조성은 신장(F=16.573, p =0.001), 체지방량(F=7.109, p =0.015)과 체지방률(F=7.667, p =0.012)에 있어 통계적으로 유의한 향상이 있었다. 둘째, 체전굴 및 체후굴 동작 수행 시 근활성도는 체후굴 동작 시 외측광근의 근활성도(F=6.140, p =0.022)에 있어 통계적으로 유의한 향상을 있었다. 셋째, 좌전굴 및체후굴 동작 수행 시의 유연성은 좌전굴(F=4.661, p =0.043)과 체후굴(F=11.650, p =0.003)에 있어 통계적으로 유의한 향상이 있었다. 넷째, 제자리 한발 서기 동작 수행 시의 균형감각은 COP X축(F=5.769, p =0.026)과 COP Y축(F=4.365, p =0.05)에 있어 통계적으로 유의한 향상이 나타났다. [결론] 본 연구는 실시간 비대면 요가가 미치는 신체적 영향에 대한 과학적인 증거를 제시할 것이다.
PURPOSE The purpose of this study was to investigate the effects of an 8-week online yoga training on body composition, muscle activity, flexibility, and balance in males (n=7) and females (n=15). METHODS Twenty-two participants were recruited and divided into two groups (Exercise group, n=11 and control group, n=11). All participants had two visits. During the visits, body composition, muscle activity for forward and back-bending poses, flexibility for sitting-forward and back-bending poses, and balance for one-leg standing were determined. After 8-week yoga training, all measurements were re-performed. An independent t-test was performed to determine the difference between the exercise and control groups. A two-way repeated measures of ANOVA was used to assess the interaction effects (group*time). All values were represented as mean ± standard deviation. An α level was set at 0.05 for all analyses. RESULTS First, the height significantly increased (F=16.573, p=0.001) and body fat mass (F=7.109, p=0.015) and body fat percent (F=7.667, p=0.012) were significantly decreased after the 8-week online yoga training. Second, the muscle activity for vatus lateralis doing a back-bending pose (F=6.140, p=0.022) significantly increased after the 8-week online yoga training. Third, the flexibility on sitting-forward bending pose (F=4.661, p=0.043) and back-bending pose (F=11.650, p=0.003) were statistically increased after the 8-week online yoga training. Lastly, balance on the Center Of Pressure (COP) X (F=5.769, p=0.026) and the Center Of Pressure (COP) Y (F=4.365, p=0.05) significantly increased after the 8-week online yoga training. CONCLUSIONS This study will provide scientific evidence on improving exercise programs using online yoga training on physical activity. © Korea Institute of Sport Science.
