The superscript symbols indicate a significant between-groups difference tested by ANOVA with Tukey post hoc test and a significant within-groups difference tested by ANOVA for repeated measure with the following value. Plasma Cys levels: MT group versus WT group pre-exs (), post-exs (), post-10 min (), and post-30 min (); WT group by time (); MT group by time (); and UT group by time (); plasma CySS levels: UT group versus WT and MT groups in pre-exs (, ), post-exs (, ), post-10 min (, ), and post-30 min (, ); WT group by time (); MT group by time (); and UT group by time (); plasma GSH levels: MT group versus WT and UT groups in pre-exs (, ), post-exs (, ), post-10 min (, ), and post-30 min (, ); plasma GSSG levels: WT group by time (), MT group by time (), and UT group by time (); RBCs  GSH levels: MT group versus UT group at post-exs (), WT group by time (), MT group by time (), and UT group by time (); RBCs GSSG levels: MT group versus WT group at post-exs () and post-10 min (), WT group by time (), and UT group by time (). The values of cortisol and creatin  kinase were increased after exercise compared to pre-exs (; tested with paired -test).
