Table 3.

Skeletal muscle reactive oxygen species (ROS), coenzyme Q10 (CoQ10) concentrations, and activities of glutathione peroxidase (GPx) and superoxide dismutase (SOD) in NACQ- and placebo-supplemented horses. Differences in superscripts indicate significant differences with supplementation or exercise. There were no significant effects of exercise or NACQ/placebo supplementation.
