Abstract

The purpose of this study was to analyze the effect of a 12 week aerobic resistance training circuit program on the health-related fitness, blood lipids, and cortisol in obese postmenopausal women. The subjects for the study were twenty obese postmenopausal women composed of the exercise group (n=10) and "no exercise" control group (n=10). The aerobic resistance training circuit program was conducted for 70 minutes 3 times a week for 12 weeks, in which the aerobic exercise consisted of 5 items each composed of 5 sets of aerobic exercise at 50-70% HRmax intensity for 1 minute for a total of 25 minutes and the resistance exercise consisted of 8 items conducted for a total of 25 minutes at 40-60% intensity of 1RM). In the exercise group, the body weight and BMI significantly decreased and the 20m shuttle run, sit-ups and sitting trunk flexion significantly increased. In the exercise group, the TC, LDL-C, and TG significantly decreased. Also, it was noted that the HDL-C was slightly higher in the exercise group than in the control group, but the difference was not statistically significant. The cortisol levels of the exercise group and control group at baseline were similar. However, after the aerobic resistance training circuit program, the exercise group had a significantly higher cortisol level than the control group. Therefore, regular and continuous aerobic resistance training was effective in improving the body composition, blood lipids and health-related fitness.

본 연구는 12주간의 유산소성 저항트레이닝 써킷이 폐경 후 비만여성의 건강체력, 혈중지질 및 코티졸(cortisol)에 미치는 영향을 알아보기 위한 것으로 운동집단(10명)과 통제집단(10명)으로 나누어 실시하였다. 유산소성 저항트레이닝 써킷 프로그램은 12주간 주 3회 회당 70분을 실시하였다. 유산소운동은 5가지 종목을 HRmax의 50-70% 강도로 종목당 1분씩 5세트로 구성하여 25분 동안 실시하였으며, 저항운동은 대상자 개인의 체중을 이용하여 8가지 종목을 주관적 운동자각도에 따라 횟수 및 세트 수를 증가시켜 25분 동안 실시하였다. 운동프로그램 실시 전과 12주 후 변인들을 측정 비교 분석하여 다음과 같은 결과를 얻었다. 운동집단에서 체중 및 BMI가 유의하게 감소하였고 심폐지구력, 근력 및 유연성이 유의하게 증가하였으며, 운동 실시 후 집단 간 심폐지구력 및 근지구력에서 유의한 차이가 있었다. 운동집단의 TC, TG 및 LDL-C가 유의하게 감소하였으며, HDL-C는 유의한 차이는 나타나지 않았지만 운동집단에서 운동 실시 후 향상되는 경향을 보였다. 코티졸은 운동 실시 후 집단 간 유의한 차이가 있었다. 이상의 결과를 볼 때 폐경 후 비만여성에게 유산소성 저항트레이닝 써킷의 적용은 건강체력, 혈중지질 및 코티졸에 긍정적인 영향을 미친 것으로 사료되며, 다양한 연령층의 비만개선을 위한 운동프로그램으로 활용할 수 있을 것으로 생각된다.
