%X This paper aims to identify factors that may account for the high values and varied prevalence of exercise-induced bronchospasm (EIB), which occur in the population of athletes. Journal articles, indexed and peer reviewed, published in the MEDLINE and SPORTDiscus database were screened using a computer search. Keywords as ¡°prevalence,¡± ¡°exercise,¡± ¡°bronchospasm,¡± and ¡°athletes¡± were crossed. The diagnosis of EIB based on the questionnaire or maximal decrease of ventilatory parameters was considered as inclusion criteria and selection of articles. Analysis of selected articles reveals higher values and varied prevalence of EIB (11¨C55%) compared to those in the general population (4¨C20%). Evaluation criteria of EIB are those based on the characteristics of sedentary subjects. Criteria sometimes do not seem adapted to specific sports. This paper suggests a differential diagnostic approach which takes account of both the EIB characteristics of sedentary and those of sportsmen. 1. Introduction Asthma and exercise-induced bronchospasm (EIB) are terms used to describe the same phenomenon depending on the path of physiological nature of the subjects and the circumstances highlighted. However, these two terms are not always interchangeable. Indeed, asthma is a multifactorial disease resulting from the combination of factors predisposing congenital (hereditary factors) and environmental factors favoring (allergens, pollen, home and industrial dusts, and air pollution inhalation, etc.). It is defined as a disorder characterized by attacks of breathlessness or chest tightness paroxysmal wheezing, usually exhalation, indicating a sharp decrease of the caliber of the bronchi which combine progressive edema and hypersecretion of mucous tract air breathing (nasal cavity, pharynx, larynx, trachea, bronchi) can lead to inflammation. Clinically, asthma is characterized by attacks of breathing difficulty arising from crises, time varying and is reversible spontaneously or under the effect of treatment. These accesses coincide with episodes of varying degrees of airway obstruction and reversible [1]. As a result, the diagnosis of asthma is very delicate. The diagnosis of asthma is based on the examination, respiratory symptoms, family history, and pulmonary function at rest, during exercise and pharmacodynamic tests. To validate this diagnosis in the resting state, the criteria of the European Respiratory Society [2] and the American Thoracic Society [3] require a ratio of forced expiratory volume in 1 second (FEV) less than 80% of the theoretical value, a ratio of FEV on
