The effect of exercise on mitochondria and myofibrils. a The formation of mitochondrial derived vesicle-like structures (indicated by the red arrow) was shown in the CLI + exercise group and the myeloid body (indicated by the yellow arrow) was found in the CLI + sedentary group. The mitochondrial length, the cross-sectional area and perimeter of mitochondria, number of mitochondrial derived vesicles, and the diameter of mitochondrial derived vesicles were quantified using image-pro plus 6.0 (n = 3 samples/group). Magnification × 15,000. b The comparison of mitochondrial length among 4 groups was conducted using ANOVA. The cross-sectional area and perimeter of mitochondria, number of mitochondrial derived vesicles, and diameter of mitochondrial derived vesicles were compared via the Mann-Whitney U test, *p < 0.05, **p<0.01
