(a) Effects of 12-week wheel-running exercise and nutrition on the cardiac 64 kDa MMP-2 activity (expressed as intensity × mm²). Results are shown as means ± S.E.M. n = 12. (b) Effects of 12-week wheel-running exercise and nutrition on the cardiac 72 kDa MMP-2 activity (expressed as intensity × mm²). Results are shown as means ± S.E.M. n = 12. Statistical significance: ^∗p < 0.05 relative to the SO CTRL group, and ^#p < 0.05 shows a significant difference between the running and nonrunning groups. SO = sham-operated; OVX = ovariectomized; CTRL = standard chow; HT = high-triglyceride diet.
