中文摘要:
      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中强度组共计4组。运动强度包括中强度(40%~55%HRR)和大强度(60%~80%HRR)2种,运动时间也包括30min/次和60min/次两种形式。同一组内实验前后的比较采用配对T检验(双尾),组间比较采用釆用单因素方差分析统计。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最多。

      Abstract: 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 non-exercise 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 middle intensity exercise group (P < 0.05). Conclusions: The 90 min high intensity exercise per week or 180 min moderate 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 moderate intensity exercise on 3 days per week, can gain more health benefits than 30 min moderate intensity exercise on 5 days per week.
