摔跤运动员血瘦素与体成分的相关性及 抗阻训练对其影响研究

目的:探讨摔跤运动员血瘦素的分泌特点、与体成分的相关性,分析一次性抗阻运动对摔跤运动员血瘦素水平的影响.方法:以男子摔跤专业运动员(n=12)为实验对象,以运动爱好者(n=14)和非运动爱好者(n=12)为对照,对安静时血瘦素的分泌特点及与体成分的关系进行分析.抗阻训练后,30min,再次测定血瘦素水平,对比研究专业组抗阻训练前后血瘦素的变化.结果:安静时,摔跤运动员血瘦素水平、体脂、体脂%及体重指数显著高于运动爱好组和非运动爱好组(P<0.05).摔跤运动员血瘦素水平与体脂、体脂%正相关(P<0.01),与体重指数间不具有相关性(P>0.05),非运动爱好组的血清瘦素与体重指数高度相关(P<0.01).但是各组间单位体脂的血清瘦素水平无显著性差异(P>0.05).摔跤运动员在进行抗阻训练后30min,血瘦素水平下降8.7%(P<0.001).结论:1)摔跤运动员体成分发生了改变;2)体脂是血瘦素水平的主要决定因素;3)一次性抗阻训练能下调男子摔跤运动员血瘦素水平.

Correlations between serum leptin concentration and body component , and effects of resistance training on it in wrestlers

This paper is to detect the characteristics and the correlations between serum leptin and body com2
ponent , and to examine acute effect s of resistance training on serum leptin in male wrestlers. Thirty eight
young men (12 for professional wrestler group , 14 for sport s lover group , and 12 for sports non2lover group)
participated in testing and analyzing serum leptin and body component . A comparative research was performed
about the changes of serum leptin concentration before and after 30 minutes of resistance training. It was
found that the serum leptin , body fat (BF) , BF % and BMI were higher in wrestlers than in sport s lovers and
sport s non2lovers. Serum leptin concentrations in wrestlers were significantly correlated to BF and BF %( P <
0. 01) , but not to BMI (P ? 0. 05) . However , no differences were found in serum leptin concentration per BF
among the three groups ( P < 0. 05) . Serum leptin concentrations in wrestlers were reduced by 8. 7 % after re2
sistance training ( P < 0. 001) . It could be seen that the body component s were changed in wrestlers. The BF
was decisive factor of serum leptin levels and resistance training could down2regulate serum leptin levels in
wrestlers.
