A Representative picture of immunohistological staining of slow myofibers (MYH7 in green) and the sarcolemma (dystrophin in red, 20 × magnification). B Minimum ferret’s diameter of type 1 and C type 2 myofibers. D Percentage of type 1 and 2 myofibers. All data were normally distributed. Values represent mean ± SEM, *p < 0.05Back to article page
