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.
