目的：比较18个月的连续与间歇性运动对有氧能力，体重和成分，代谢健身在以前久坐，中度肥胖femines.DESIGN：随机，前瞻性，长期队列研究。受试者以最大有氧能力的60-75%进行连续运动，每周3天，每次30分钟，或每周5天间歇性快走两次，每次15分钟。结果：连续运动组和间歇运动组的有氧能力分别提高了8%和6%。连续运动组的体重减轻显著，较基线体重减少2.1%，间歇运动组基本不变。连续组的体脂百分比和脂肪重量显着下降，而间歇组没有。HDL胆固醇和胰岛素显着改善为both groups.CONCLUSIONS：在以前久坐，中度肥胖的女性，连续或间歇性运动进行长期可能是有效的，防止体重增加，并为改善代谢健身的一些措施。
OBJECTIVES: To compare the effects of 18 months of continuous vs intermittent exercise on aerobic capacity, body weight and composition, and metabolic fitness in previously sedentary, moderately obese females.DESIGN: Randomized, prospective, long-term cohort study. Subjects performed continuous exercise at 60-75% of maximum aerobic capacity, 3 days per week, 30 min per session, or exercised intermittently using brisk walking for two, 15 min sessions, 5 days per week.MEASURES: Aerobic capacity, body weight, body composition, and metabolic fitness (blood pressure, lipids, glucose and insulin).RESULTS: Significant improvements for aerobic capacity of 8% and 6% were shown for the continuous and intermittent exercise groups, respectively. Weight loss for the continuous exercise group was significant at 2.1% from baseline weight and the intermittent group was essentially unchanged. The continuous group showed a significant decrease in percentage of body fat and fat weight while the intermittent group did not. HDL cholesterol and insulin were significantly improved for both groups.CONCLUSIONS: In previously sedentary, moderately obese females, continuous or intermittent exercise performed long-term may be effective for preventing weight gain and for improving some measures of metabolic fitness.
