Citrate synthase activity (a), size (b,d), and complexity (c,e) of interfibrillar (IFM; (b,c)) and subsarcolemmal (SSM; (d,e)) mitochondria from Musculus gastrocnemius of rats with inherited high (HCR) or low (LCR) exercise capacity with and without exercise training; data are mean ± SEM, blue—HCR, orange—LCR, light color—IFM, dark color—SSM, FS—forward scatter, SS—sideward scatter, G—inherited exercise capacity, Ex—exercise training, I—interaction, ns—non-significant, n = 6–13, * p < 0.05, ** p < 0.01, and *** p < 0.001 for G, Ex, I, or compared tothe same group without exercise training, †† p < 0.01 and ††† p < 0.001 compared to HCR with the same treatment. Two-way ANOVA was performed.
