目的:探讨肥胖患者补锌和有氧运动前后体重指数和血清瘦素(leptin)水平的变化。方法:将2 6名16～2 3岁男性肥胖患者按体重指数随机分为补锌+有氧运动组和有氧运动组,采用放射免疫分析法(RIA)测定实验前、实验第4周、第8周、第12周血清瘦素水平并计算BMI。结果:补锌+有氧运动组实验中与实验前相比,第4周血清瘦素水平显著升高(P <0 . 0 5 ) ;补锌+有氧运动组BMI值较实验前显著降低,第8周与有氧运动组相比有显著性差异。(P <0 . 0 5 )。结果提示,补充锌使肥胖患者运动减肥的效果更明显。
Objective: To investigate the changes of body mass index and serum leptin level before and after zinc supplementation and aerobic exercise in obese patients. Methods: Twenty-six male obesity patients aged 16 to 23 years were randomly divided into zinc supplementation + aerobic exercise group and aerobic exercise group according to their body mass index. Before radioimmunoassay (RIA) 8th week, 12th week serum leptin level and calculated BMI. Results: The levels of serum leptin in the zinc supplemented + aerobic exercise group were significantly increased at the 4th week (P <0.05), and the BMI values in the zinc supplemented + aerobic exercise group were significantly lower than those before the experiment There was a significant difference between the 8th week and the aerobic exercise group. (P <0.05). The results suggest that supplemental zinc to obesity patients exercise more effective weight loss.
