In a previous review in this journal McFadden eloquently presented the findings which led him and his colleagues to propose that respiratory heat loss and the subsequent cooling of the airways are the initial reaction sequence leading to airway obstruction in hyperventilation and exercise-induced asthma [62]. He further concluded that: "Exercise per se is not essential and serves only as means to increase ventilation". Our interpretation of currently available data has led us to conclude that while respiratory heat loss may play an important permissive role in initiating the bronchoconstriction which follows exercise, the weight of evidence indicates that exercise per se serves as the trigger mechanism and is not just a tool to increase ventilation. Moreover, we believe that the role of exercise in releasing chemical mediators has been established, although pathways by which the airway smooth muscle is affected are still uncertain.
