Exercise-induced bronchoconstriction(EIB) is defined as a transient airway obstruction that follows a modest period of high intensity exercise. Accumulating evidence demonstrated that EIB is reported not only among patients with asthma (EIBA), but also observed in a signifi- cant number of individuals without a known diagnosis of asthma (EIBWA). Accordingly, most recent guidelines have been largely revised. Since EIBA have different pathological back- ground from that in EIBwA, EIBA and EIBwa might have distinct responses to treatment and prevention despite using similar therapeutic strategies. This article aims to present a brief review on the current understandings of clinical features, pathogenesis, and management of both types of EIB.
