Postprandial lipid clearance failure and lipoprotein disorders, which are independent risk factors for cardiovascular diseases are well-recognized in type II diabetes. Reduction of fats through exercise has been proved, though the mechanism is not well-defined, and the effects of different intensity exercise on postprandial lipidemia in diabetes type II is unknown. This study aims to find these effects using a cycle ergometer.
On three different days, 15 type II diabetics (10 women and 5 men, with a mean age 42.07 ± 6.05 years, weight 94.64 ± 4.37 kg, height 159.78 ± 9.09 cm, and body mass index29.83 ± 3.93 kg/m2), consumed a full fat breakfast (750-800 kcal, 85% fat), and 150 min later, blood samples were taken from them to measure their lipid profile. The 1st day was the control day, without any exercises. Seven days later, 90 min after enriched breakfast, they did 30 min of exercise on the cycle ergometer with intensity of 55-70% of maximum heart rate (HRmax), and 14 days later, 90 min after enriched breakfast, they did 30 min of exercise with intensity of 70-85% of HRmax.
According to Friedman non-parametric test, high-density lipoprotein (HDL) cholesterol serum level significantly increased after 30 min of moderate intensity exercise (P > 0.05, from 39.4 ± 5.2 to 48.6 ± 9.3), while this increase was insignificant after a higher intensity exercise. Neither intensity levels had any significant effects on triglyceride or on low-density lipoprotein cholesterol.
Results showed that moderate intensity exercise was more effective in increasing HDL cholesterol level in type II diabetics.
餐后脂质清除障碍和脂蛋白紊乱是心血管疾病的独立危险因素,在II型糖尿病中已得到充分认识。运动减脂已被证实,但其机制尚不明确,不同强度运动对II型糖尿病患者餐后血脂的影响也不清楚。本研究旨在通过功率自行车来探究这些影响。
在三个不同的日子里,15名II型糖尿病患者(10名女性和5名男性,平均年龄42.07±6.05岁,体重94.64±4.37千克,身高159.78±9.09厘米,体重指数29.83±3.93千克/平方米)食用了一顿高脂早餐(750 - 800千卡,85%为脂肪),150分钟后采集他们的血样以测量血脂谱。第一天为对照日,不进行任何运动。七天后,在丰盛早餐90分钟后,他们在功率自行车上进行了30分钟的运动,强度为最大心率(HRmax)的55 - 70%,14天后,在丰盛早餐90分钟后,他们进行了30分钟强度为HRmax的70 - 85%的运动。
根据弗里德曼非参数检验,中等强度运动30分钟后高密度脂蛋白(HDL)胆固醇血清水平显著升高(P>0.05,从39.4±
