摘要
目的:通过观察4周运动结合饮食控制后,肥胖青少年在快速体重下降过程中身体形态及甘油三酯(TG)、高密度脂蛋白(HDL)等生化指标的变化,探讨体成分、脂肪代谢的机制。方法:公开募得51名单纯性肥胖青少年进行为期4周的有氧运动结合饮食控制的干预活动,根据受试者不同的身体状况进行营养配餐、制定运动方案,分别在干预前、后测试肥胖青少年的身体形态及血液生化指标。结果:4周后由于各种原因,最终43名青少年完成计划。干预后肥胖青少年体重呈显著下降(P<0.01),体脂含量显著下降(P<0.01),总胆固醇(TC)无变化,甘油三酯(TG)、低密度脂蛋白(LDL)显著下降(P<0.01),意外发现高密度脂蛋白(HDL)出现显著下降(P<0.01)。结论:4周有氧运动结合饮食控制可作为运动减肥的有效干预模式,能显著降低体重、体脂、TC、LDL水平,但对TG无显著影响。4周内快速降体重HDL出现降低可能与节食时控制脂肪摄入量有关,所以短期减重的过程中应该逐步降低营养配餐中脂肪的比例,防止出现HDL下降的情况。
Objective.. to observe the change of the body chape and the blood lipip indexes in a rapid weight loss during a short period（4 weeks）, and discusses and merchanism of body composition and fat metablism. Methods： 51 simple obese adolescents participants a 4--weeks intervetion of aerobic exercise combined with diet control,43 finished in the end. The training program was based on the different physical condition of the subjects and strictly control the calerio intake. Tested the body shape and the blood lipid indexes before and after the intervetion. Result： After the interven tion, obese teens＇ weight were significantly decreased （P^0.01）, body fat mass decreased significantly （P%0. 01）. Total cholesterol （TC） wasn＇t change, triglyceride （TG）, low density lipoprotein （LDL） decreased significantly （P d0.01）. An unexpected outcome was the high--density lipoprotein （HDL） decreased significantly （P^0. 01）. Con clusion： A 4--weeks of aerobic exercise combined with diet control can be used as an effective exercise for weight loss intervention , can significantly reduce the body weight, body fat, TC and LDL levels, but had no significant effect on TG. IN rapid weight loss progress, HDL appeared lower may be associated with a less fat intake, so in the process of short--term weight loss program should gradually reduce the percentage of fat in the nutrition catering, in order to prevent a drop on HDL.
