Short-Duration Swimming Exercise after Myocardial Infarction Attenuates Cardiac Dysfunction and Regulates Mitochondrial Quality Control in Aged Mice
Figure 3
Short-duration exercise after MI modulates mitochondrial morphology and dynamics in aged heart. (a) Representative transmission electron micrographs of cardiac mitochondria. Scale bars, 1 μm. (b) Frequency distribution (% total mitochondria) of the mitochondrial surface area. . (c–i) Western blot analysis of mitochondrial fission and fusion markers. versus the sham group; , versus the MI-sedentary group; versus the MI + 15’ ST group. .
