Short-term changes in respiratory biomarkers
CBPs have a strong oxidizing potential and may contribute to airway
damage through opening tight junctions, causing barrier
disruption19,20. A summary of the studies describing
short-term changes in respiratory biomarkers is presented inTable 1 . It is important to note that some of these studies did
not measure NCl3 and/or did not compare with a
non-chlorinated-pool, which precludes drawing clear conclusions. The
role of physical activity should not be neglected in this type of
studies measuring biomarkers before and after swimming.
