Effect of N-acetylcysteine on Cycling Performance after Intensified Training

Purpose This investigation examined the ergogenic effect of short-term oral N-acetylcysteine (NAC) supplementation and the associated changes in redox balance and inflammation during intense training. Methods A double-blind randomized placebo-controlled crossover design was used to assess 9 d of oral NAC supplementation (1200 mg·d−1) in 10 well-trained triathletes. For each supplement trial (NAC and placebo), baseline venous blood and urine...
