摘要
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 - tolerance training. Methods The recruited young soldiers were divided into 2 groups：Group Ⅰ （50 coming from the northern region）and group 11 （50 coming from the southern region） . According to the new training outline of cold -tolerance in winter,their ventilatory functions were tested before training and 60 days after training. Ventilatory functions were compared between smoking and non - smoking subjects. 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 between smoking and non - smoking subjects. Conclusion Cold air could decline the small airway function of soldiers coming from southern region before training. Cold - tolerance training has significant influence on soldiers＇ ventilatory function. Long - term and heavy smoking could decline the small airway function.
