Diagnostic algorithm for exercise-induced bronchoconstriction (EIB). NB: Criteria for bronchodilator reversibility and a positive provocation test result may vary (i.e. >12% and 200mL increase in forced expiratory volume in 1 second (FEV1). For more information see GINA 2011 document, ATS/ERS criteria and the International Olympic Committee (β2-adrenoceptor agonists and the Olympic Games in Beijing; http://www.olympic.org). It may also be necessary for athletes to repeat a bronchoprovocation test if negative initially. Note that other investigations such as marked peak flow variability may be used to support a diagnosis of asthma
