The objective of this study was to analyze the effects of strength training on plasma homocysteine levels and cardiovascular risk factors in patients with type 2 diabetes.
The sample consisted of 14 diabetic women with a mean age of 68 ± 6 years. Biochemical evaluations and anthropometric measurements were taken before and after training. Training sessions lasted 50 min and comprised three sets of 8-12 repetitions each. The established load was 60% of 1 repetition maximum.
After the training program, it was observed that the levels of homocysteine (average before 13.4 ± 2.9 and after 12.8 ± 3.3, = 0.40), very low-density lipoprotein (LDL) (average before 41.9 ± 17.0 and after 36.2 ± 11.8, = 0.47), total cholesterol (average before 214.4 ± 60.6 and after 190.2 ± 62.3, = 0.09), triglycerides (average before 209.3 ± 85.4 and after 181.5 ± 59.2, = 0.47), and blood glucose (average before 123.5 ± 30.4 and after 110.1 ± 24.7, = 0.26) showed no significant changes, but the LDL (average before 129.1 ± 63.4 and after 95.7 ± 53.3, = 0.04), high-density lipoprotein (average before 43.2 ± 12.0 and after 58.2 ± 15.6, = 0.01), lean mass (average before 41.1 ± 5.7 and after 42.8 ± 5.4, = 0.008), fat mass (average before 31.4 ± 8.8 and after 29.7 ± 8.5, = 0.001), and percentage fat (average before 42.6 ± 4.0 and after 40.3 ± 4.6, = 0.000) showed significant changes.
This study concluded that strength training does not improve homocysteine levels, but help to improve the lipoprotein profile in type 2 diabetic patients.
本研究的目的是分析力量训练对2型糖尿病患者血浆同型半胱氨酸水平及心血管危险因素的影响。
样本包括14名平均年龄为68±6岁的糖尿病女性。在训练前后进行生化评估和人体测量。训练课程持续50分钟，每组包括8 - 12次重复动作，共三组。设定的负荷为1次最大重复量的60%。
训练计划结束后，观察到同型半胱氨酸水平（训练前平均为13.4±2.9，训练后为12.8±3.3，P = 0.40）、极低密度脂蛋白（LDL）（训练前平均为41.9±17.0，训练后为36.2±11.8，P = 0.47）、总胆固醇（训练前平均为214.4±60.6，训练后为190.2±62.3，P = 0.09）、甘油三酯（训练前平均为209.3±85.4，训练后为181.5±59.2，P = 0.47）和血糖（训练前平均为123.5±30.4，训练后为110.1±24.7，P = 0.26）均无显著变化，但LDL（训练前平均为129.1±63.4，训练后为95.7±53.3，P = 0.04）、高密度脂蛋白（训练前平均为43.2±12.0，训练后为58.2±15.6，P = 0.01）、去脂体重（训练前平均为41.1±5.7，训练后为42.8±5.4，P = 0.008）、脂肪量（训练前平均为31.4±8.8，训练后为29.7±8.5，P = 0.001）和脂肪百分比（训练前平均为42.6±4.0，训练后为40.3±4.6，P = 0.000）有显著变化。
本研究得出结论，力量训练不能改善同型半胱氨酸水平，但有助于改善2型糖尿病患者的脂蛋白谱。
