有氧运动结合玉米肽对超重、肥胖女大学生脂肪代谢的影响

The Effect of Corn Peptide on Plasma FFA and LPS of Overweight and Obesity Female College Students

目的:探讨有氧运动结合玉米肽对超重、肥胖女大学生脂肪代谢的影响。方法:将29名女大学生随机分为对照组与玉米肽组,两组均进行4周有氧运动,在运动同时,玉米肽组每天补充玉米肽,对照组补充同等质量的蛋白粉安慰剂;观察实验前后检测两组被检者的体质指数(BMI)、血浆游离脂肪酸(FFA)与脂肪酶(LPS)活性等指标。结果:与对照组相比,实验后玉米肽组女大学生的体重、BMI与体脂率显著下降(P<0.05),血浆FFA含量显著增加(P<0.05),LPS活性显著增强(P<0.05),脂肪动员效率提高。结论:4周有氧运动结合玉米肽干预对超重、肥胖女大学生的BMI与体脂率均有改善作用,这可能与玉米肽提高LPS活性从而改善脂代谢有关。

Objective ： To investigate the effect of corn peptide on fat metabolism of overweight and o- besity female college students. Methods： Twenty-nine female college students were randomly divided into control group and corn peptide group, then the students of both groups took aerobic exercises for four weeks, meanwhile corn peptide group were supplied corn peptide every day and control group were supplied with equal amount protein placebo. Before and after the experiment, index like BMI, FFA and LPS were tested for both groups. Results： Compared with the control group, the weight, the body mass index and the body fat percentage of the students in corn peptide group decreased （P 〈 0.05 ）, the content of FFA in the blood plasma obviously increased （P 〈 0.05 ）, the LPS reactor apparently en- hanced （ P 〈 0.05 ）, the efficiency of fat mobilization increased. Conclusion： The 4 weeks aerobic ex- ercise combined with corn peptide have positive effect on the weight, the body mass index and the body fat percentage for the overweight and the obesity female college students, which could be possible that corn peptide increase the activity of LPS.
