将16名青年男子分为训练组和对照组(每组8人),训练组在热室(Td34.5℃)平板机仁进行模拟越野训练,两周共10次(天),热应激标准试验显示,获得了热习服。清晨血清T_3增加7%,T_4降低3.3%,T_4/T_3比值由46降至42;血清CS5/8受试者降低,ALD降低18.6%,血清T增高13.3%,T/CS比值增高26.6%(从0.079增至0.100);尿VMA增高10.5%。对照组则相反,血清T_3降低5%,T_4增加16.8%(超过正常值上限),与训练组比较P<0.01,T_4/T_3比值由46增至57(P<0.05),与训练组比较P<0.01;CS增高46.8%,与训练组比较P<0.05;ALD增高13.2%,较训练组高37.9%;血清T无变化;T/CS比值降低25.3%,由0.075降至0.056,比训练组低44%。
Sixteen young men were divided into training group and control group (8 in each group). The training group simulated cross-country training in the hot chamber (Td34.5 ℃) tablet machine, two times a total of 10 times (days), heat stress Standard tests show that a thermal accretion has been obtained. In early morning serum T 3 increased 7%, T 4 reduced 3.3%, T 4 / T 3 decreased from 46 to 42; serum CS 5/8 decreased, ALD decreased 18.6%, serum T increased 13.3% and T / CS increased 26.6% From 0.079 to 0.100); urinary VMA increased by 10.5%. Compared with the training group, P <0.01, the ratio of T_4 / T_3 was increased from 46 to 57 (P <0.05), compared with the training group, the P value of the control group was decreased by 5% and T_4 increased by 16.8% <0.01; CS increased 46.8% compared with the training group P <0.05; ALD increased 13.2%, 37.9% higher than the training group; serum T did not change; T / CS ratio decreased by 25.3% from 0.075 to 0.056 than the training group 44% lower.
