(A, B) Western blotting results of apoptosis-related proteins Bax and Bcl-2 in myocardial tissues (n = 3). (C) BAX/Bcl-2 protein blotting ratio. (D-E) Relative activity of Caspase-3 and Cleaved Caspase-3 enzyme in myocardial tissue using enzyme markers (n = 6). The values are presented as the mean ± SEM. SE, S+ exercise group; S, sham group; MI, myocardial infarct group; ME, MI+ exercise group. *P<0.05, **P<0.01.
