Gerontol. (2020) Online first The second investigates Exercise induced Asthma in swimmers and highlights issues with chlorine being in the pool environment but not in the testing "Diagnosis of Exercise-induced Bronchoconstriction in Swimmers: Context Matters. " Med. Sci. Sports Exerc. (2020) Pre View Hope you get something from it , and you can link to the written review and the papers by subscribing to the review
