Effects of MI and AIT on mitochondrial respiratory function. After 8 weeks, the rats were killed, and mitochondrial respiration functions were evaluated. (A) State 3 of cardiac mitochondrial respiration; (B) State 4 of cardiac mitochondrial respiration; (C) Cardiac mitochondrial respiratory control ratio (RCR = State 3/State 4); and (D) P/O ratio for each group. The significance of the differences was calculated using one-way ANOVA followed by Tukey’s post-hoc test. The data are presented as the means ± SEM (n = 10). * p < 0.05 vs. the sham group, ^ p < 0.05 vs. the MI group. Sham: sham operation; MI: myocardial infarction; MI + AIT: myocardial infarcted rats subjected to aerobic interval training.
