The International Olympic Committee Medical Commission (IOC-MC) now requires athletes to provide evidence for beta(2) agonist use. Eucapnic voluntary hyperpnoea (EVH) is the recommended test to diagnose exercise-induced bronchoconstriction (EIB).

Area of Science:

  • Sports Medicine
  • Pulmonary Physiology
  • Anti-Doping Regulations

Background:

  • The International Olympic Committee Medical Commission (IOC-MC) mandates notification for beta(2) agonist use during the Winter Olympic Games.
  • This notification requires objective evidence justifying the need for medication seven days prior to the event.

Purpose of the Study:

  • To outline the IOC-MC's stance on beta(2) agonist use in elite athletes.
  • To present eucapnic voluntary hyperpnoea (EVH) as the optimal laboratory method for diagnosing exercise-induced bronchoconstriction (EIB).

Main Methods:

  • The study describes the eucapnic voluntary hyperpnoea (EVH) test, a specific challenge test designed to identify EIB.
  • The EVH test involves subjects hyperventilating dry air with 5% carbon dioxide for six minutes.

  • Ventilation is targeted at 30 times the subject's forced expiratory volume in one second (FEV(1)), with conditions adjustable to mimic athlete-specific triggers.

    • Main Results:

    • A positive test for EIB is defined as a 10% or greater reduction in FEV(1) compared to pre-test values.
    • EVH has a proven track record, having been successfully performed in thousands of subjects in both laboratory and field settings.

    Conclusions:

    • Eucapnic voluntary hyperpnoea (EVH) is currently considered the gold standard for confirming exercise-induced bronchoconstriction (EIB) in athletes.
    • The IOC-MC utilizes EVH results to validate the necessity of beta(2) agonist use in competitive sports.
