研究表明，高密度脂蛋白（HDL）胆固醇水平高和低密度脂蛋白（LDL）胆固醇水平低与老年妇女的健康维护有关，但少数研究已经检查了运动和血浆脂蛋白水平之间的关系，在这个老年人群一直模棱两可。此外，还没有研究探讨血浆脂蛋白反应的两种不同类型的运动在一组积极的但不运动的妇女。因此，运动训练对老年妇女血浆脂蛋白水平的影响尚不清楚。本研究的目的是研究耐力和抗阻运动对老年妇女血浆脂蛋白水平的影响，这些妇女在研究之前是活跃的但不运动。共有45名年龄在70-87岁的健康活跃女性被随机分配到有氧训练组（AT，76 +/- 5岁，n = 15）、阻力训练组（RT，73 +/- 3岁，n = 15）或对照组（C，74 +/- 5岁，n = 15）。AT组每周步行3天，心率储备为70%。第1天的持续时间为20分钟，每天增加5分钟，直至受试者步行50分钟（第3周）。RT组的运动训练包括一至三组8种不同运动的8次重复，最多重复8次; C组保持正常活动。各组的体重和饮食没有变化。运动干预持续10周。在第0周和第11周采集所有受试者的血液样本。训练导致AT组1英里步行时间和步行完成时的心率显著下降，所有RT运动的最大重复次数显著增加。与第0周相比，AT组和RT组在第11周均发生HDL胆固醇升高和甘油三酯降低。对照脂蛋白无阳性变化。甘油三酯和总胆固醇与HDL的比值均显著增加，而总胆固醇、HDL胆固醇和LDL胆固醇保持不变。在第11周，RT组的LDL胆固醇和总胆固醇也显著低于对照组。RT和耐力训练导致老年妇女血浆脂蛋白水平在10周内发生了有利的变化。事实上，这发生在没有同时改变，八或饮食是一个迹象表明，高强度运动单独可以用来修改健康老年妇女人群中的脂蛋白。
It has been shown that high levels of high-density lipoprotein (HDL) cholesterol and low levels of low-density lipoprotein (LDL) cholesterol are associated with health maintenance in older women, but the few studies that have examined the relationship between exercise and plasma lipoprotein levels in this elderly Population have been equivocal. In addition, there are no studies that examine the plasma lipoprotein response of two different types of exercise in a group of active hut nonexercising women. Thus, the effects Of exercise training on plasma lipoprotein levels in elderly women remain unclear. The purpose of this research was to examine the effects of endurance and resistance exercise on plasma lipoprotein levels in elderly women who were active but nonexercising prior to the study. A total of 45 healthy, active women, aged 70-87 years, were randomly assigned to either an aerobic training (AT, 76 +/- 5 years, n = 15), resistance training (RT, 73 +/- 3 years, n = 15), or control (C, 74 +/- 5 years, n = 15) group. The AT group walked 3 days a week at 70% heart rate reserve. The duration on day 1 was 20 minutes, and it was increased by 5 minutes each day until subjects were walking for 50 minutes (week 3). The exercise training session for the RT group consisted of one to three sets of eight repetitions of eight different exercises at an eight repetition maximum; the C group maintained normal activity. Weight and diet were unchanged across groups. The exercise interventions lasted 10 weeks. Blood samples were obtained from all subjects at week 0 and week 11. Training resulted in a significant decrease in 1-mile walk times and heart rate at completion of the walk for the AT group and a significant increase in eight repetition maximum of all RT exercises. Both AT and RT group, experienced increased HDL cholesterol and decreased triglycerides at week 11 compared with week 0. There were no positive changes in control lipoproteins. Both triglycerides and the total cholesterol to HDL ratio increased significantly while total cholesterol, HDL cholesterol, and LDL cholesterol remained unchanged. The RT group also had significantly lower LDL cholesterol and total cholesterol compared with controls at week 11. Both RT and endurance training resulted in favorable changes to plasma lipoprotein levels for elderly women in only 10 weeks. The fact that this occurred without concurrent changes in ,eight or diet is an indication that high-intensity exercise alone can be used to modify lipoproteins in populations of healthy elderly women.
