Acute respiratory illness (ARill) is common and threatens the health of athletes. ARill in athletes forms a significant component of the work of Sport and Exercise Medicine (SEM) clinicians. The aim of this consensus is to provide the SEM clinician with an overview and practical clinical approach to non-infective ARill in athletes. The International Olympic Committee (IOC) Medical and Scientific Committee appointed an international consensus group to review ARill in athletes. Key areas of ARill in athletes were originally identified and six subgroups of the IOC Consensus group established to review the following aspects: (1) epidemiology/risk factors for ARill, (2) infective ARill, (3) non-infective ARill, (4) acute asthma/exercise-induced bronchoconstriction and related conditions, (5) effects of ARill on exercise/sports performance, medical complications/return-to-sport (RTS) and (6) acute nasal/laryngeal obstruction presenting as ARill. Following several reviews conducted by subgroups, the sections of the consensus documents were allocated to ‘core’ members for drafting and internal review. An advanced draft of the consensus document was discussed during a meeting of the main consensus core group, and final edits were completed prior to submission of the manuscript. This document (part 2) of this consensus focuses on respiratory conditions causing non-infective ARill in athletes. These include non-inflammatory obstructive nasal, laryngeal, tracheal or bronchial conditions or non-infective inflammatory conditions of the respiratory epithelium that affect the upper and/or lower airways, frequently as a continuum. The following aspects of more common as well as lesser-known non-infective ARill in athletes are reviewed: epidemiology, risk factors, pathology/pathophysiology, clinical presentation and diagnosis, management, prevention, medical considerations and risks of illness during exercise, effects of illness on exercise/sports performance and RTS guidelines.

国际奥委会（IOC）关于运动员急性呼吸道疾病的共识声明第 2 部分：非感染性急性呼吸道疾病

急性呼吸道疾病 (ARill) 很常见，威胁着运动员的健康。运动员中的 ARill 是运动与运动医学 (SEM) 临床医生工作的重要组成部分。该共识的目的是为 SEM 临床医生提供运动员非感染性 ARill 的概述和实用的临床方法。国际奥委会 (IOC) 医学和科学委员会任命了一个国际共识小组来审查运动员的 ARill。最初确定了运动员中 ARill 的关键领域，并建立了 IOC 共识小组的六个亚组，以审查以下方面：（1）ARill 的流行病学/危险因素，（2）感染性 ARill，（3）非感染性 ARill，（4 ) 急性哮喘/运动引起的支气管收缩和相关疾病，(5) ARill 对运动/运动表现的影响，医疗并发症/恢复运动 (RTS) 和 (6) 表现为 ARill 的急性鼻/喉阻塞。在小组进行了几次审查之后，共识文件的各个部分被分配给“核心”成员进行起草和内部审查。在主要共识核心小组会议期间讨论了共识文件的高级草案，并在提交手稿之前完成了最终编辑。本共识文件（第 2 部分）重点关注导致运动员非感染性 ARill 的呼吸系统疾病。这些包括非炎性阻塞性鼻、喉、气管或支气管病症或呼吸道上皮的非感染性炎症病症，其影响上气道和/或下气道，通常作为连续体。
