摘　　要：目的:分析不同剂量运动对静坐少动中年女性心血管健康的影响,进而更好地为中年女性静坐少动者参加体育活动提供指导。方法:在控制运动时间和运动强度双因素后,通过对240名静坐少动中年女性进行为期3个月不同剂量的运动干预实验,并随机分成不运动对照组、30 min中强度组、30 min大强度组、60 min中强度组共4组。运动强度包括中强度(40%~55%HRR)和大强度(60%~80%HRR)2种,运动时间包括30 min/次和60 min/次这2种形式。同一组内实验前后的比较采用配对T检验(双尾),组间比较采用单因素方差分析。结果:只有30 min大强度组和60 min中强度组受试者的BMI、体脂比、腰臀比出现了差异(P<0.05)。结论:每周进行90 min大强度运动或者每周进行180 min中强度运动,对于降低肥胖风险具有重要的意义。每周进行3次30 min大强度运动或每周进行3次60 min中强度运动在心血管健康风险方面的效益均比每周进行5次30 min中强度运动所获得的健康效益多。Objective： This study analyzed the effects of different doses of exercise on the cardiovascular health of middle-aged women with sedentary behavior,aimed to provide better guidance for middle-aged sedentary women to participate in physical exercise. Methods： The 240 middle-aged sedentary women were randomly divided into nonexercise control group,30 min medium intensity（ 40% -55% HRR） exercise group,30 min high intensity（ 60% -80% HRR） exercise group and 60 min medium intensity（ 40% -55% HRR） exercise group,and women in exercise groups finished three months exercise. The paired T test（ double tail） was used in the group comparison（ before and after experiment）,and the one-way ANOVA was used for the comparison between groups. Results：There were significances of BMI,body fat ratio and waist-to-hip ratio in 30 min high intensity exercise group and 60 min medium intensity exercise group（ P〈0. 05）. Conclusions： The 90 min high intensity exercise per week or 180 min medium intensity exercise per week is of great significance in reducing the risk of obesity; 30 min high intensity exercise on 3 days per week or 60 min medium intensity exercise on 3 days per week,can gain more health benefits than 30 min medium intensity exercise on 5 days per week.
