A member asked:
Help please? i want to know what are the impacts of exercise and caffeine on pulmonary function testing?
A doctor has provided 1 answer
Improvements: in lung function testing, albeit mild. Caffeine has similar but much less potent effects as an old asthma medication known as theophylline(a bronchodilatory). It has been shown to improve FEV1 and mid‐expiratory flow rates by 5% or so. Exercise seems to have more wide sweeping effects in PFTs(even more so in asthmatic patients) than caffeine but again the overall effect is still modest.
