Figure 3: Changes of GSH-redox system components in the serum levels. Participants were taken control treatment or yoga training class for 12 weeks. Serum levels of total GSH contents (A) GSH-peroxidase activities (B) and GSH-reductase activities (C) were measured from serum samples after 12 weeks each class. Data were expressed as means ± SD (n=12 control group, n=13 yoga group, respectively). The p-value was compared with the change values of control group.
