Abstract
Almost all asthmatics are prone to asthma triggered by moderate to severe exercise. Fortunately there are a number of pharmaceutical agents now available which can prevent and/or reverse exercise-induced asthma (EIA) and allow many asthmatics to participate in vigorous physical activities with minimum respiratory disadvantage. Regular exercise is an accepted part of the management of asthma and EIA can now be controlled so successfully that a number of elite sportspersons, in almost all types of sporting events, are asthmatic. This control of EIA, which is essential if asthmatics are to participate safely, requires that the patient and his/her doctor initiate a strategy to manage the disease during sport and other physical activities. In recent years the mortality and morbidity from asthma have been increasing and this has indicated the need to improve patient care. One of the most important innovations aiming to improve the control and treatment of asthma has been the recent development of the 6 point asthma management plan which is a strategy to simplify and optimise the long term management of asthma. It aims to improve the quality of life of most asthmatics and more importantly, prevent deaths due to asthma. Because antidoping controls operate in many high performance sports it is essential that the EIA management plan rely on those medications which are permitted. The list of allowable drugs is in continual flux as new ones are added and others are challenged on the grounds of possible ergogenicity. All aerosol β2-agonists except fenoterol, the khellin derivatives, theophylline, ipratropium bromide and the aerosol corticosteroids are currently permitted. Some nonasthmatic athletes who are aware of the improved performance of asthmatic athletes when using pre-exercise medication have been known to take antiasthma medication in the hope that it might improve their performance. Current evidence indicates, however, that the permitted medications are not ergogenic and do not give the asthmatic any advantage over the nonasthmatic athlete but merely removes the respiratory disadvantage under which he/she competes.
