长期高温高强度训练对武警阅兵队员血清睾酮与皮质醇的影响

Effects of intensive exercise on blood testosterone and cortisone among military parade troops from Armed Police Forces

目的研究长期高温、高强度训练对武警阅兵战士血清睾酮(T)和皮质醇(C)的影响。方法用酶免法测定长期在高温、高强度下训练的武警阅兵战士血清睾酮和皮质醇水平,计算睾酮/皮质醇比值(T/C),以接受常规训练的武警战士作为对照。结果阅兵组血清睾酮平均(17.3±6.1)nmol/L,显著低于对照组(22.0±8.9)nmol/L,差异有统计学意义(P<0.05);阅兵组血清皮质醇平均(407.0±127.4)nmol/L,显著低于对照组(530.8±206.7)nmol/L,差异有统计学意义(P<0.01);而阅兵组T/C值为0.048,与对照组0.05比较,差异无统计学意义(P=0.44)。结论长期高温、高强度训练导致武警阅兵战士血清睾酮水平和血清皮质醇水平下降,T/C值在阅兵组与对照组无统计学差别,说明阅兵组训练强度合适。

Objective To study the effect of intensive exercise on serum testosterone and cortisone in military parade troops from the Armed Police Forces.Method Thirty-four subjects in the military parade troops were recruited for this study as high-intensity exercise group while 26 subjects in other troops who received routine exercise served as control group.The participants underwent a thorough physical examination.Blood concentrations of testosterone and cortisone were determined by chemiluminescent immunoassay.Results The level of plasma testosterone in high-intensive exercise group was lower than in control group,（17.3±6.1） nmol/L vs（22±8.9） nmol/L,P〈0.05,so was the level of plasma cortisone（407±127.4） nmol/L vs（530.8±206.7） nmol/L,P0.01.The ratio of testosterone/cortisone（T/C） in both groups was not different（0.048 vs 0.05,P=0.44）.Conclusions Extensive exercise decreases both blood testosterone and blood cortisone while the ratio of T/C is not different between high-intensive exercise group and control group.
