Which sport is most likely to trigger bronchospasm in patients with exercise-induced asthma?

Cross-country skiing is most likely to trigger bronchospasm in patients with exercise-induced asthma due to the specific environmental conditions and demands of the sport. This activity typically takes place in cold, dry air, which is known to exacerbate asthma symptoms. The combination of the cold air and the high level of aerobic exertion required during cross-country skiing can lead to increased respiratory heat and water loss, contributing to bronchospasm.

Additionally, this sport often requires sustained periods of intense physical exertion, which can further challenge individuals with asthma as their respiratory system works harder to meet oxygen demands. While other sports like basketball, soccer, and swimming involve varying levels of intensity and environmental factors, they generally take place in different conditions that may be less likely to provoke bronchospasm in asthmatics compared to the cold, dry, and prolonged exertion associated with cross-country skiing.
