目的：研究海军飞行员运动心肺功能的特点,分析体重指数( BMI)对海军飞行员运动心肺功能的影响。方法对30名海军飞行员(海军飞行员组)和15名普通健康男性(健康男性对照组)进行运动心肺功能测试,对比海军飞行员与普通健康男性运动心肺功能各项指标的差异；同时按BMI<22(偏瘦组,n=5)、22~26(正常组,n=13)及≥26(偏胖组,n=12)将30名飞行员进行分组,分析各组运动心肺功能各项指标的差异。结果海军飞行员组整体运动心肺功能优于健康男性对照组(P<0.05)；飞行员不同BMI组间运动心肺功能比较,正常组最佳(P<0.05, P<0.01),偏瘦组优于偏胖组(P<0.05)。结论 BMI变化可影响海军飞行员的运动心肺功能,偏低或偏高均可导致运动心肺功能下降,合理控制体重可增强飞行员的运动心肺能力,从而更好地适应飞行作业。%Objective To study the features of the cardiopulmonary function of naval pilots and to analyze BMI influence on cardiopulmonary exercise function. Methods The cardiopulmonary exercise test was performed for 30 naval pilots ( group A) and 15 common healthy males ( group B) to compare the differences in cardiopulmonary function inde-xes by the test;and the 30 naval pilots were divided into subgroup A (BMI<22, n=5), subgroup B (22≤BMI<26, n=13) and subgroup C (BMI>26, n=12), and the differences in cardiopulmonary function indexes in all the groups were analyzed. Results The overall athletic cardiopulmonary function of group A was better than that in group B ( P<0. 05);and among the three subgroups, cardiopulmonary function indexes in subgroup B were the best one (P<0. 05,P<0. 01), and the indexes in subgroup A was superior compared with those in subgroup C (P<0. 05). Conclusion The BMI change may affect the athletic cardiopulmonary function of naval pilots, and under or over weight of the pilots may weaken the cardiopulmonary function, so appropriate weight control can improve cardiopulmonary athletic ability of the pilots.
