Oral Nitrate Reduction Is Not Impaired After Training In Chlorinated Swimming Pool Water In Elite Swimmers

This study tested the hypothesis that exposure to chlorine-sterilised pool water would impair oral nitrate reduction (ONR). ONR was assessed in elite swimmers before and after morning and afternoon pool-based training. Nonswimmers were only assessed in the morning. ONR was similar in swimmers and nonswimmers (P = 1.000) and unchanged before and after morning and afternoon training (P >= 0.341). Therefore, exposure to chlorinated pool water does not interfere with ONR.Novelty:Exposure to chlorine-sterilised pool water does not impair oral nitrate reduction in elite swimmers.
