Studies show that different types of training have a significant role in reducing both new and traditional risk factors of cardiovascular diseases, and the new risk factors are more sensitive and accurate in predicting such diseases.
The aim of this study was to determine the effects of resistance and endurance exercises on risk factors of vascular inflammation and atherogenesis in non-athlete men.
Thirty-six non-athlete male students (mean age: 20.45 ± 1.20 years; mean body mass index: 23.66 ± 3.65 kg/m) were randomly assigned into either three groups: control group, resistance training (RT), and endurance training (ET). The training groups exercised for 3 days/week for 8 weeks. ET group performed treadmill-running at 65%-80% of maximum heart rate and with a 16-30 min duration; the task of RT group consisted of three repetition sets, 8-10 per set, at 60%-80% of one repetition maximum, with 2-min recesses. Blood samples were taken before and after the training program. Data were analyzed by Shapiro-Wilk test, one-way ANOVA, LSD test, and dependent -test (α ≤ 0.05).
The results indicated a significant reduction in total cholesterol levels in both RT and ET groups. Also high-density lipoprotein cholesterol significantly increased in both training groups. In addition, following 8 weeks, low-density lipoprotein cholesterol in ET group was significantly decreased, whereas these training methods have had no significant effects on the new cardiovascular biomarkers (hs-CRP, IL-6, and sICAM-1).
It seems that both ET and RT with improvement in lipid profiles could be effective in prevention and treatment of the cardiovascular disease.
研究表明，不同类型的训练在降低心血管疾病的新老危险因素方面具有重要作用，且新危险因素在预测此类疾病时更为敏感和准确。
本研究旨在确定抗阻训练和耐力训练对非运动员男性血管炎症和动脉粥样硬化危险因素的影响。
36名非运动员男学生（平均年龄：20.45±1.20岁；平均体重指数：23.66±3.65kg/m²）被随机分为三组：对照组、抗阻训练组（RT）和耐力训练组（ET）。训练组每周训练3天，共8周。ET组在跑步机上以最大心率的65%-80%跑步，持续16-30分钟；RT组的任务包括三组重复训练，每组8-10次，强度为一次重复最大值的60%-80%，每组间休息2分钟。在训练计划前后采集血样。数据采用夏皮罗-威尔克检验、单因素方差分析、LSD检验和配对检验（α≤0.05）进行分析。
结果表明，RT组和ET组的总胆固醇水平均显著降低。此外，两个训练组的高密度脂蛋白胆固醇均显著升高。此外，8周后，ET组的低密度脂蛋白胆固醇显著降低，而这些训练方法对新的心血管生物标志物（hs-CRP、IL-6和sICAM-1）没有显著影响。
似乎ET和RT通过改善血脂状况，都可能对心血管疾病的预防和治疗有效。
