Exercise-Induced Asthma - Possible Influences of Chloramine: A Case Study

This study documented the difference in post-exercise lung capacities following swimming or treadmill running at matched intensities. A 21-year old female diagnosed with exercise-induced asthma completed two exercise bouts matched for caloric expenditure. The first consisted of swimming the backstroke for 1 min at 75yd/min. The second consisted of a treadmill run at 5.6 mph for 1 min. Forced vital capacity (FVC) and Forced Expiratory Volume in 1 Minute (FEV1) were assessed 30 s post-exercise using a Pneumoscan S-300 spirometer. Compared to resting values, post-exercise FVC was more greatly diminished (-17.9%) following the swim as opposed to the run (-10%). FEV1 was reduced by 11.5% following the swim vs. a 3.6% reduction post-run. FEV1/FVC ratio was increased slightly above resting values following both exercises (+5.4% swim, +5.8% run). The greater reduction in FEV1 and FVC following swimming may be attributable to the effect of pool surface chloramines.
