Supplementation with NAC also augmented postexercise plasma total antioxidant capacity ( P = @ , p = @ ) , reduced exercise-induced oxidative damage ( plasma thiobarbituric acid-reactive substances , P = @ , p = @ ; urinary @-isoprostane F@t concentration , P = @ , p = @ ) , attenuated inflammation ( plasma interleukin @ , P = @ , p = @ ; monocyte chemotactic protein @ , P = @ , p = @ ) , and increased postexercise nuclear factor B activity ( P < @ , p = @ ) .
