健身锻炼对老年男子性激素水平的影响

Effect of exercises on sex hormones in elder men

目的:探讨健身运动对老年男子性激素水平的影响。方法:13名老年男子采用功率自行车进行14周递增负荷有氧运动,实验前、第8周、结束时采血测定睾酮、雌二醇、促滤泡成熟激素(folliclestimulatinghormone,FSH)、促黄体生成激素(luteinizinghormone,LH)。结果:老年男子血浆睾酮处于正常值低限水平,实验结束时差异性不显著(t=1.556,P>0.05)。血浆雌二醇处于正常值中等水平,实验结束时较实验前下降了44.36%(t=2.599,P<0.05)。实验结束时雌二醇/睾酮比值较实验前下降明显,差异性显著(t=2.486,P<0.05)。血浆FSH大于正常值水平,实验结束时下降8.52%(t=2.320,P<0.05)。血浆LH处于正常值下限水平,实验中呈逐渐上升变化(t=4.213,P<0.01)。结论:递增负荷有氧运动可显著降低血浆雌二醇水平和雌二醇/睾酮比值,降低血浆FSH水平,提高血浆LH水平,有利于老年男子性能力向着良性方向发展。

AIM:To investigate the influence of exercise on sex hormones in old men. METHODS:Thirteen old men were taken an aerobic exercise program with gradually increasing load by using cycle ergometer for 14 weeks.Testosterone(T),estrediol(E2),follicle stimulating hormone (FSH) and luteinizing hormone(LH) were determined before,8 and 14 weeks after exercise. RESULTS:Plasma T level in old men was at the low standard and there was no significant difference after aerobic exercise program (t=1.556,P >0.05);Plasma E2 level was at the middle standard and was decreased by 44.36%as compared with that before exercise(t=2.559,P< 0.05);Meanwhile,E2/T was significantly decreased as compared with that before exercise(t=2.486,P< 0.05);Plasma FSH level was higher than standard level and decreased by 8.52%after aerobic exercise program(t=2.320,P< 0.05);Plasma LH level was the at the low standard and gradually increased during the exercise(t=4.213,P >0.01).CONCLUSION:Aerobic exercises with gradually increasing load can effectively decrease the plasma E2 level,E2/T and FSH levels and increase LH level in old men,and it is benefit for their sexual ability.
