摘　　要：目的探讨两种不同频率运动结合饮食指导对肥胖干预的效果。方法纳入140例18~60岁且体质指数(BMI)≥28kg/m2的肥胖患者,随机分为低频率运动组(3次/周,每次100 min)和高频率运动组(6次/周,每次50 min)。进行为期24周的运动与饮食干预,比较干预前后两组肥胖患者体重、血压等指标变化差异。结果干预后,两组肥胖患者的收缩压、舒张压、体重、BMI、腰围、体脂百分比、三酰甘油、低密度脂蛋白及总胆固醇均下降,高密度脂蛋白水平升高(P<0.05);两组患者收缩压、舒张压、体重、BMI、腰围、三酰甘油、高密度脂蛋白、低密度脂蛋白及总胆固醇水平比较,差异均无统计学意义(P>0.05);低频率运动组肥胖患者体脂百分比下降更明显(P<0.05)。结论饮食指导结合运动干预可有效改善肥胖患者体重、血压和血脂等指标,在保证每周总有氧运动时间相同的基础上,低频率运动减脂效果更好。Objective To discuss the effects of different exercise frequency and diet guidance for fat loss on obese patients,and to develop a safe and effective multidisciplinary intervention program for obese patients.Methods A total of 140 members of Ningbo Slimming Club were recruited,with the age between 18-60 years,body mass index(BMI)greater than 28 kg/m2,and they were randomly assigned to low frequency group and high frequency group.In low frequency group,the intervention was complete 100 minutes aerobic exercise and 3 times a week.In high frequency group,the intervention was complete 50 minutes of aerobic exercise and 6 times a week.Each group followed the same diet weight loss program.By comparing each index before and after the intervention,the effect of fat loss was evaluated.Results After intervention,systolic blood pressure,diastolic blood pressure,body weight,BMI,waist circumference,body fat percentage,triglyceride,low density lipoprotein and total cholesterol in two groups were decreased,and high density lipoprotein were increased(P<0.05).Compared between the low frequency and high frequency exercise group,there were no significant difference for the systolic blood pressure,diastolic blood pressure,body weight,waist circumference,BMI,triglyceride,high density lipoprotein,low density lipoprotein and total cholesterol levels(P>0.05),but body fat percentage in low frequency exercise group decreased significantly(P<0.05).Conclusion Diet intervention combined with exercise has a significant effect of fat loss on obese patients.Based on the same weekly aerobic exercise time,obese patients with low frequency of exercise had better fat loss than obese patients with high frequency of exercise.
