【 摘 要 】

Physical training can adapt or cause injury to skeletal muscles implicating metabolic alterations, which can be detected by biochemical analysis. Apparently the increase in the production of reactive oxygen species (ROS) is involved in both processes. Enzymatic and low molecular weight antioxidants (LMWA) minimize ROS's deleterious action through redox reactions. Cyclic voltammetry (CV) has been suggested as a tool to quantify the antioxidant capacity conferred by LMWA. The use of CV to evaluate the modulation of the antioxidant capacity conferred by LMWA in response to physical exercise is discussed here.
