目的研究来自不同地区青年耐寒锻炼前后肺通气功能的变化.方法选取驻哈尔滨某部当年入伍的新兵,分为两组;Ⅰ组为来自寒区的新兵50人(吉林省吉林地区),Ⅱ组为来自非寒区的新兵50人(河南信阳);按照新兵训练大纲进行耐寒锻炼,分别于锻炼前和锻炼后60天测定受试者的肺通气功能.并比较吸烟者和非吸烟者肺通气功能指标.结果训练前,Ⅰ组新兵的25%呼气流速(FEF25%)、50%呼气流速(FEF50%)和75%呼气流速(FEF75%)3项肺通气功能指标均高于Ⅱ组新兵,且有显著性差异(P<0.05);而其他肺通气功能指标两组间无显著性差异(P>0.05).训练后60天,两组新兵的肺通气功能指标均显著高于训练前(P<0.01,P<0.05),而两组间比较各项指标均无显著性差异.在训练前和训练60天后,新兵小气道功能的部分指标吸烟组和非吸烟组比较有显著性差异(P<0.05).结论寒冷气候对来自非寒区的新兵训练前小气道功能有一定影响,而经过耐寒锻炼60天后,来自寒区和非寒区新兵的肺通气功能均显著提高,增强了新入伍战士对寒冷环境的适应能力.同时长期大量吸烟对小气道功能有一定损害.

Objective To study the changes of ventilatory function of young soldiers coming from different regions during cold - tol-erance training. Methods The recruited young soldiers were divided into 2 groups:Group Ⅰ (50 coming from the northern region)and group Ⅱ (50 coming from the southern region) . According to the new training outline of cold -tolerance in winter,their ventilatory func-tions were tested before training and 60 days after training. Ventilatory functions were compared between smoking and non - smoking sub-jects. Results 25% forced expiratory flow (FEF25%) , 50% forced expiratory flow (FEF50%) and 75% forced expiratory flow (FEF75 %) were significant different between two groups before the course of training (P < 0.05). After 60 days, ventilatory functions of two groups were improved significantly as compared with that before training (P <0.01 ,P <0.05). There was no significant difference in ventilatory between two groups after 60 days of training (P > 0.05). There was significant difference in partial small airway function be-tween smoking and non - smoking subjects. Conclusion Cold air could decline the small airway function of soldiers coming from south-ern region before training. Cold -tolerance training has significant influence on soldiers' ventilatory function. Long- term and heavy smok-ing could decline the small airway function.
