摘要： 目的探讨8周有氧耐力运动对体质量正常和肥胖大鼠摄食量、身体成分和血脂影响的差异性。方法采用高脂饮食建立营养性肥胖大鼠模型,然后将肥胖模型大鼠随机分为肥胖安静组(OC组)和肥胖运动组(OE组),另设普通饲料安静组(NC组)和普通饲料运动组(NE组),运动组进行8周有氧耐力运动。整个实验过程中每日计算摄食量,运动干预结束后,应用双能X线骨密度仪测量大鼠身体成分,全自动生化分析仪检测血脂。结果 1)NE组第1、4、7周的摄食量均显著低于NC组(P<0.05) ;OE组第1、2、3、4、6、8周的摄食量均显著低于OC组(P<0.05)。2)与OC组比较,OE组全身脂肪组织量和全身脂肪百分比均显著下降(P<0.05),但NE和NC组间均无显著差异(P>0.05)。3)OE组全身肌肉组织量和全身肌肉百分比均显著高于OC组(P<0.05),但NE和NC组间均无显著差异(P>0.05)。4)NE组全身骨密度显著高于NC组(P<0.05),但OE和OC组间无显著差异(P>0.05)。5)OE组血清TG水平显著低于OC组(P<0.05),但NE和NC组间无显著差异(P>0.05)。结论相同强度的有氧耐力运动对体质量正常和肥胖大鼠的摄食量、脂肪组织量、肌肉组织量、全身骨密度以及血清TG水平的影响存在差异性。

Abstract: Objective To study the differences of food consumption, body composition and blood lipids between normal-weight and obese rats during eight weeks aerobic endurance exercise. Methods Firstly, a rat model of nutritional obesity was established by feeding with a high-fat diet, and then these obese rats were randomly divided into two groups, obesity control (OC) group, and obesity exercise (OE) group.In addition, a normal control (NC) group and a normal exercise (NE) group were set up. After grouped, the exercise groups were arranged for eight weeks aerobic endurance exercise . During the experimental period, diet consumption of the rats was measured every day afternoon. After the exercise intervention , body composition of the rats was determined with Prodigy dual-energy X-ray absorptiometry, and blood lipids with the automatic biochemistry analyzer. Results 1) Diet consumptions of 1,4,7-week in NE group were significantly lower than that in NC group (P<0.05); Diet consumptions of 1,2,3,4,6,8 -week in OE group were significantly lower than that in OC group (P<0.05); 2) Compared with OC group, whole-body adipose tissue mass and body fat percentage were significantly decreased in OE group (P<0.05), but there was no significant difference between NE group and NC group (P>0.05); 3)Whole-body muscle tissue mass and muscle percentage in OE group were significantly higher than that in OC group (P<0.05), but there was no significant difference between NE group and NC group (P>0.05); 4)Whole-body bone mineral density in NE group increased, was significantly greater than that in NC group (P<0.05), but there was no significant difference between OE group and OC group (P>0.05); 5) serum TG levels in OE group were significantly lower than that in OC group (P<0.05), but there was no significant difference between NE group and NC group (P>0.05). Conclusion The same intensity aerobic endurance exercise caused different effects on food consumption, whole-body adipose tissue mass, muscle tissue mass, bone mineral density and serum TG levels between normal-weight and obese rats.
