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. Non-swimmers were only assessed in the morning. ONR was similar in swimmers and non-swimmers (P = 1.000) and unchanged pre to post morning and afternoon training (P ≥ 0.341). Therefore, exposure to chlorinated pool water does not interfere with ONR. Novelty Bullet Point Exposure to chlorine sterilised pool water does not impair oral nitrate reduction in elite swimmers.
