Figure 4.  Comparison of the chronic exercise effect and /or high cholesterol diet on red cell GPX activity (A) and plasma TAC concentration (B) among four groups in rabbits. Data are expressed as mean ± SD (n=15 for each group).Differences of p<0.05 were considered significant. $ NE vs. NC * HC vs. NC and NE # HE vs. NC and NE † HE vs. HC Abbreviations: NC = normal diet control, NE = normal diet with exercise, HC= high cholesterol diet control, HE = high cholesterol diet with exercise, GPX = glutathione peroxidase, MDA = malondialdehyde.
