Objective: The large amount of evidence and the renewed interest in upper and lower airways involvement in infectious and inflammatory diseases has led Interasma (Global Asthma Association) to take a position on United Airways Diseases (UAD). Methods: Starting from an extensive literature review, Interasma executive committee discussed and...

Elite competitive swimmers are particularly affected by airway disorders that are probably related to regular and intense training sessions in a chlorinated environment. Upper and lower airway respiratory symptoms, rhinitis, airway hyper-responsiveness, and exercise-induced bronchoconstriction are highly prevalent in these athletes, but their...

Concerns have been expressed about the possible detrimental effects of chlorine derivatives in indoor swimming pool environments. Indeed, a controversy has arisen regarding the possibility that chlorine commonly used worldwide as a disinfectant favors the development of asthma and allergic diseases. The effects of swimming in indoor chlorinated...

Introduction: Skiers and swimmers present characteristics of airway inflammation and remodelling of the extracellular matrix similar to what is observed in mild asthma. We aimed to compare serum and sputum MMP-9/TIMP-1 levels, to assess the balance between airway fibrogenesis and inflammation process in both categories of athletes, and to...

ackground: Airway hyperresponsiveness is highly prevalent in competitive swimmers, but it is unknown whether this is transient or persistent.Objectives: To document changes in airway responsiveness and airway inflammation in elite swimmers during intense training and rest.Methods: Nineteen swimmers and 16 healthy controls completed a...

Background: Exercise-induced cough is common among athletes. Athletes training in cold air often report an increasingly troublesome cough during the winter season. Chronic airway irritation or inflammation may increase the sensory response of cough receptors. The aim of this study was to evaluate the seasonal variability of cough reflex...

This study was aimed at the following: (1) the prevalence of airway hyperresponsiveness (AHR) and exercise-induced bronchoconstriction (EIB) in swimmers and winter sport athletes according to the previously recommended regulatory sport agencies criteria, (2) the relationship between respiratory symptoms and AHR/EIB, (3) the impact of the chosen...

Objective: Self-reported respiratory symptoms are poor predictors of exercise-induced bronchoconstriction (EIB) in athletes. The objective of this study was to determine whether athletes have an inadequate perception of bronchoconstriction.Methods: One hundred thirty athletes and 32 nonathletes completed a standardized questionnaire and...

Regular physical activity is recognized as an effective health promotion measure. Among various activities, swimming is preferred by a large portion of the population. Although swimming is generally beneficial to a person's overall health, recent data suggest that it may also sometimes have detrimental effects on the respiratory system....

Background: The importance of exercise-induced exaggerated blood pressure (BP) response in endurance athletes is not known.Objective: To assess the hemodynamic parameters and metabolic profile in athletes with an exaggerated BP response to exercise.Methods: Forty-four endurance athletes underwent a maximal exercise test, a 24-h ambulatory blood...
