Cold Air Exposure at − 15 °C Induces More Airway Symptoms and Epithelial Stress During Heavy Exercise Than Rest Without Aggravated Airway Constriction
European journal of applied physiology(2022)
摘要
Exposure to cold air may harm the airways. It is unclear to what extent heavy exercise adds to the cold-induced effects on peripheral airways, airway epithelium, and systemic immunity among healthy individuals. We investigated acute effects of heavy exercise in sub-zero temperatures on the healthy airways. Twenty-nine healthy individuals underwent whole body exposures to cold air in an environmental chamber at − 15 °C for 50 min on two occasions; a 35-min exercise protocol consisting of a 5-min warm-up followed by 2 × 15 min of running at 85
