【 摘 要 】

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