Gelatinolytic activity of pro-MMP-2 and pro-MMP-9 in hearts from trained and control mice. (A) Zymography analysis illustrates two digetion bands corresponding to the latent forms of MMP-2 and MMP-9. As control groups did not show any remarkable difference, only C0 group is shown. (B) Band intensity was quantified by computer-assisted image analysis calculating pixel number of signal per cm² and significant differences within and between sedentary and trained groups were evaluated. (#P < 0.05 T30 and T45 vs. C samples and T15; ФP < 0.05 T45 vs. T30 *P < 0.05 T15 vs. C samples, T30, T45).
