   摘要
   背景：已知肺功能随时间逐渐下降。通气高于正常人群的运动员其气道损伤具有潜在增加趋势。这意味着患有支气管哮喘(BA)的运动员由于哮喘慢性炎症和运动导致的过度通气而导致其气道损伤的风险加倍。
   目的：本研究目的在于评估随时间进展的较高通气是否会引起运动员气道损伤，以及充分治疗BA是否可以预防不必要的气道损伤。
   设计：一项回顾性研究。
   人群：奥林匹克队优秀运动员。
   主要结果评估：本研究共纳入88例年龄大于18岁、参加过2008年北京和2012年伦敦奥运会、并进行过肺功能检测的运动员。运动员肺功能检测结果收集于北京和伦敦奥运会比赛前的医学鉴定期间。比较四年内肺功能检测参数的变化与其预测值，以明确运动是否会影响运动员的肺功能。根据既往史、现病史以及BA治疗史将运动员分为4组。
   结果：与FEV1(第1秒用力呼气量)预测值相比，有BA既往史的运动员的FEV1具有恶化趋势。然而4年内的变化值并没有显著性差异。另外，进行了充分治疗的哮喘运动员其FEV1值未显示与预测值有差异，且该值在4年内没有显示出任何分布学的变化。
   结论：运动员的肺功能随着时间逐渐下降。本研究提示，对哪些进行了适当BA治疗的哮喘运动员，运动可能不会加重其气道的异常阻塞。

ABSTRACT
BACKGROUND: It is known that the pulmonary function shows a decline over time. There is the potential for an increase of airway damage among athletes who have higher ventilation compared with normal population. This means that the athletes with BA are suffering the doubled risk of airway damage due to their chronic inflammation of asthma and hyperventilation by sport.
OBJECTIVE: The purpose of this study is to investigate if higher ventilation over time causes airway damage among athletes and the adequate treatment for BA prevents unnecessary airway damage.
DESIGN: A retrospective study.
SETTING: Elite athletes, Olympic team.
MAIN OUTCOME MEASUREMENT: 88 athletes older than 18 years old who participated both Beijing (2008) and London (2012) Olympic Games and underwent spirometry were included in this study. Spirometry measurements of athletes were collected at the pre-competition medical assessment before Beijing and London Olympic Games. The change in the values of spirometry parameters over four years was compared with its predictive values to verify if sports affect athlete's pulmonary function. Athletes were categorized into 4 groups depending on past history, present illness and treatment history of BA.
RESULTS: Athletes who had a past history of BA have a tendency for the worse value than the predictive value in FEV1(forced expiratory volume in one second). However the change of value over four years has not shown significant difference. The other hand, asthmatic athletes who have an adequate treatment have not shown a different value to predictive values and the value did not show any chorological change over four years.
CONCLUSION: The decline of pulmonary function over time was found in athletes. Our study suggests that exercise may not affect the aggravation of obstructive abnormality on asthmatic athletes with a proper treatment for BA.
