Figure 10. Effects of 12-week physical exercise and high triglyceride diet on cardiac MPO activity (expressed as nmol/mg protein). Values are means ±S.E.M (n = 6-8). Statistical significance: ○○○○ p < 0.0001, ○○ p < 0.01 as compared to SO CTRL NR group and #### p < 0.0001, ### p < 0.001 a significant difference between non-running (NR) and running (R) animals. SO = sham-operated, OVX = ovariectomized, CTRL = standard chow, HT = high-triglyceride, NR= non-running, R = running.
