본 연구는 복부비만여성을 대상으로 심폐지구력 수준을 구분하고 저강도 유산소운동과 고강도 유산소운동을 12주간 주 3회 실시하여 신체구성과 아디포싸이토카인, 면역관련인자와 항산화능력의 변화를 관찰하고자 실시하였다. 허리둘레가 85cm이상인 복부비만여성 38명을 대상으로 심폐지구력의 백분위의 50%인 33.3-35.2ml/kg/min을 기준으로 낮은 심폐지구력집단과 높은 심폐지구력집단으로 분류하였다. 그리고 각 집단에서 다시 저강도 및 고강도 유산소운동으로 구분하여 운동프로그램을 실시하였다. 집단 및 시기의 차이와 상호작용을 분석하기 위해 반복측정분산분석을 실시하였으며 차이가 나타난 경우 처치 전·후 사후검증은 대응 t 검증을 실시하였고 집단 간 사후검증은 Scheffe를 실시하였다. 그 결과 고강도 유산소운동은 체중, 체지방률 및 허리둘레와 아디포넥틴에 효과적이지만 TNF-α(tumor necrosis factor-α)와 IL-6(interleukin-6)는 심폐지구력 수준과 운동강도에 따른 차이가 나타나지 않았다. 또한 낮은 심폐지구력보다 높은 심폐지구력 수준이 IgM(Immunoglobulin M)의 농도가 높았고 MDA(malondialdehyde)는 높은 심폐지구력 수준에서 운동강도에 따라 차이가 나타났으며 SOD(superoxide dismutase)는 고강도 유산소운동이 가장 효과적이었다. 따라서 복부비만여성에게 유산소 운동강도를 처방할 때는 심폐지구력 수준을 고려해야한다.
This study was conducted to observe the change of body composition, adipocytokine, immune related factors and antioxidant ability. The low intensity aerobic exercise and high intensity aerobic exercise was carried out for three times a week during twelve weeks. The participants were the abdominal obese women who classified by the cardiorespiratory fitness level. The participants were the abdominal obese women who have the over 85cm of waist measurement and they were divided into two group according to the middle VO2max, 33.3-35.2ml/kg/min, which were low cardiorespiratory fitness level group and high cardiorespiratory fitness level group. The participants of this study were 38. The repeated measure ANOVA was conducted to analyze the differences and interactions between groups and periods. In the case of any difference, t-test was conducted to perform post hoc test between pre and post treatment and the Scheffe was conducted to perform post hoc test between groups. As a result, high intensity aerobic exercise was effective on weight, % fat, waist measurement and adiponectin. However, there were no differences in tumor necrosis factor-α(TNF-α) and interleukin-6(IL-6) according to the cardiorespiratory fitness level and exercise intensity. Also, higher Immunoglobulin M(IgM) showed high cardiorespiratory fitness level better than low cardiorespiratory fitness level. higher malondialdehyde(MDA) showed according to high intensity aerobic exercise in the high cardiorespiratory fitness level and the high intensity aerobic exercise was most effective for change of superoxide dismutase(SOD). Therefore, the cardiorespiratory fitness level should be considered when prescribing aerobic exercise intensity for abdominal obese women.
