[Exercise-induced asthma].

Physical exercise and, in particular, sport activities put strain on the respiratory system due to increased. Though healthy subjects undergo a light distension of the respiratory passages, those with bronchial hyperreactivity experience a decrease of lung function. The main triggers responsible are the relative cooling down, drying up and--compared to healthy subjects--overfast airway rewarming. Though, for this reason, basically every asthma patient can expect to suffer the effects of exercise-induced asthma, the solution is not in overprotection and the avoidance of all physical effort. Thanks to dosed, physical activity training programs, any asthmatic can be included in school sports or, as an adult, take part in sports and leisure activities, even at an above-average level.
