| 目的测定湿热环境训练组与空白对照组运动后血钾、钠离子浓度和白细胞计数,探讨运动后上述指标变化与机体对湿热环境习服的关系。方法选取某大学59名年龄18~23岁的男性健康志愿者,随机分为训练组30人、对照组29人,清晨空腹抽取上肢静脉血,测定血中的钾、钠离子浓度和白细胞计数；训练组进行为期6周的湿热环境体能训练,对照组未进行任何训练,随后对两组人员进行湿热环境下的踏步与负重跑运动测试,并于次晨取上肢静脉血测定钾、钠离子浓度和白细胞计数。结果训练前两组人员的血中钾、钠离子浓度和白细胞计数均无统计学差异；运动测试后,对照组血钾浓度相比训练组较训练前的基础值升高(F=9.27, P=0.003 5)；训练组、对照组的血清钠浓度在运动测试后均较训练前基础值升高,而对照组升高则更明显(F=366.46, P<0.000 1)；较训练前的基础值对照组白细胞总数相比训练组升高(F=10.20,P=0.002 3)；在白细胞分类计数中,运动后的中性粒细胞绝对计数和比例升高(F=12.25, P=0.000 9; F=9.45, P=0.003 2),其他白细胞成分的变化不明显。结论湿热环境下体能习服训练有利于提高机体运动及调节能力。 |

| Abstract: |
| ObjectiveTo identify the effects of humid heat environment conditioning on the serum K+, Na+ concentrations and blood leukocyte count after weight-loading physical ability test (PAT), and to investigate the parameter changes with humid heat environment conditioning. MethodsA total of 59 male healthy volunteers, aged 18-23 years old, were divided into two groups, with 30 in the training group and 29 in the control group. The fasting venous blood samples were taken in the morning in both groups for determination of serum K+, Na+ concentrations and blood leukocyte count. The subjects in the training group received physical training (weight-loading) under humid heat environment condition for 6 weeks, and those in the control group received no training. Then the serum K+, Na+ concentrations and blood leukocyte count were determined again the next morning after they had participated a weight-loading PAT. Results The serum K+, Na+ concentrations and blood leukocyte counts were similar in the 2 groups before training. The increase of electrolyte concentration after PAT was more prominent in the control group compared with the baseline level before training in the training group (F=9.27, P=0.003 5; F=366.46, P＜0.000 1 for K+ and Na+, respectively). Meanwhile, the control group also exhibited a significant elevation of total leukocyte count after PAT compared with the baseline level before training in the training group (F=10.20, P=0.002 3), mainly attributable to the increase of neutrophils (F=12.25, P=0.000 9). Conclusion The post-PAT serum Na+, K+ concentrations and white blood cell count, mainly neutrophils count, increase much more remarkably in the subjects undergoing no training in humid heat environment than those have been trained in humid heat environment. |
