【摘要】：目的:40-49岁年龄段正处于心肺功能下降的高峰期,缺乏反映其机能变化的指标群。分析不同运动量与心肺适能以及心血管健康之间是否存在着剂量-效应关系,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和运动处方的制定提供依据。方法:本研究通过对40-49岁静坐少动女性进行身体活动问卷测试,并从中进一步筛选满足实验要求的受试者89名。通过采用运动心肺测试系统和功率自行车测试后,筛选了83名受试者参加为期3个月不同剂量的运动干预实验,并随机分成四组:(1)不运动对照组;(2)小量中强度组;(3)小量大强度组;(4)大量中强度组。干预方案是针对运动量和运动强度所进行的双因素控制,运动强度包括中强度(40-55%HRR)和大强度(60-80%HRR)两种,单次运动量也括小运动量(30min/次)和大运动量(60min/次)。采用逻辑(Logistic)回归分析,分析不同运动量与心肺适能以及心血管健康之间是否存在着剂量-效应关系。结果:心肺耐力组与心血管健康组之间的关系主要体现在第一维度上。实验前后不同组别的心肺耐力指标呈显出一定的变化。从组别上看,对照组实验前后各指标没有出现显著性差异(p0.05),其他三个运动干预组实验前后出现一定的显著性差异(p0.05)。结论:每周进行180min大量中强度运动对于血压的改善有一定的促进作用,而且这种阈值效应呈现出平滑的曲线关系。小量中强度组(150min/周)的总胆固醇值和大量中强度组的甘油三酯值随着运动时间的提高出现降低,小量大强度组(90min/周)的低密度脂蛋白值先升高后保持平稳,大量中强度组(180min/周)的低密度脂蛋白值随着运动时间的增加呈现出一条平滑的下降曲线。
[Abstract]:Objective to study the peak of cardiopulmonary function decline in the 40-49 age group. To analyze whether there is a dose-effect relationship between different exercise and cardiopulmonary fitness and cardiovascular health. And then better provide guidance for middle-aged women sedentary women to participate in sports activities and the formulation of exercise prescription. Methods: this study through 40-49 years old sedentary women with physical activity questionnaire test. Among them, 89 subjects who met the requirements of the experiment were further selected. After using the exercise cardiopulmonary test system and the power bicycle test. Eighty-three subjects were selected to participate in the exercise intervention experiment of different doses for 3 months, and were randomly divided into four groups: control group without exercise. (2) medium strength group; (3) small amount of large intensity group; Intervention program is a double factor control for exercise quantity and intensity. The exercise intensity includes moderate strength (40-55 HRR) and high strength (60-80 HRR). The single exercise volume also included 30 min / time of small exercise and 60 min / time of large exercise. Logistic regression analysis was used. To analyze whether there is a dose-effect relationship between different amount of exercise and cardiopulmonary fitness and cardiovascular health. The relationship between cardiopulmonary endurance group and cardiovascular health group is mainly reflected in the first dimension. In the control group, there was no significant difference in each index before and after the experiment (p 0.05). There was a significant difference between the other three exercise intervention groups before and after the experiment. Conclusion: a large number of moderate exercise for 180 minutes per week can promote the improvement of blood pressure. Moreover, the threshold effect showed a smooth curve relationship. The total cholesterol value of the medium intensity group and the triglyceride value of a large number of medium intensity group decreased with the increase of exercise time. The low density lipoprotein (LDL-C) of the small dose of high intensity group (90 min / week) increased first and then remained stable. The low density lipoprotein (LDL) values of a large number of moderate strength groups (180 min / week) showed a smooth decreasing curve with the increase of exercise time.
