Fifty-five healthy sedentary non smoking and non obese 24-26-year-old men with a low serum concentration of HDL-cholesterol were selected for a study of the effect of nine weeks of exercise on glucose homeostasis, and blood testosterone. The participants were randomized into two groups. Twenty-eight subjects were assigned to a nine-week program of submaximal aerobic exercise three times weekly, while 27 were assigned to a non exercising control group. The improvement in physical fitness was assessed by change in estimated oxygen consumption (EVO2 max) that was increased by 15% in the exercise group (p less than 0.001), but remained unchanged in the control group. During the study the body weight of both groups remained essentially unchanged. There was a significant reduction of mean plasma fructosamine in the exercise group, and non significant reduction in serum insulin. Serum testosterone, glycohemoglobin and HDL-cholesterol were not influenced by exercise, while serum triglycerides were significantly reduced.
55名健康的久坐不动、不吸烟且不肥胖的24至26岁男性被选入一项研究，该研究旨在探究为期九周的运动对葡萄糖稳态和血液睾酮水平的影响，这些男性的高密度脂蛋白胆固醇血清浓度较低。参与者被随机分为两组。28名受试者被分配到一个为期九周的次最大有氧运动计划中，每周进行三次，而27名被分配到非运动对照组。通过估计耗氧量（EVO2 max）的变化来评估体能改善情况，运动组的EVO2 max增加了15%（p<0.001），而对照组则保持不变。在研究期间，两组的体重基本保持不变。运动组的平均血浆果糖胺显著降低，血清胰岛素有非显著性降低。血清睾酮、糖化血红蛋白和高密度脂蛋白胆固醇不受运动影响，而血清甘油三酯显著降低。
