"Competitive swimmers who train at indoor chlorinated swimming pools may have lung changes similar to those seen in people with mild asthma, a new study has found.
Researchers from France and Canada compared lung tissue and breathing tests from twenty-three elite Canadian swimmers, whose average age was 21, to ten mild asthmatics and 10 healthy, non-allergic people of the same age. Tissue samples and tests were taken during the off-season when swimmers were not competing."
