Correlations between autophagy or mitochondria marker proteins in cardiac muscles and exercise performance after 10 weeks of exercise training. Positive correlations of time to exhaustion with LC3-II/LC3-I ratio (a), ATG-3 (b), ATG-12 (c), and ATG-16L (d). Positive correlations of time to exhaustion with SDH (e) and COX IV content (f) in cardiac muscles. Negative correlation of IE-LA with SDH (g) and COX IV (h) in cardiac muscles. Pearson correlations were conducted for the above analyses (n = 12, pooled samples of SC, CMT, and HIIT groups). IE-LA, blood lactate levels immediately post-exercise
