Figure 4:

A. Mitochondrial volume varied across DIAm fiber types (p<0.0001; one-way ANOVA). The mitochondrial volumes of type IIx/IIb fibers were significantly larger than those of both type I and IIa fibers (p<0.0001; Tukey’s post hoc test) Mitochondrial volumes of type I and IIa fibers were not different. B. Mitochondrial volume density varied across fiber types (p<0.0001; one-way ANOVA). Mitochondrial volume densities in type I and type IIa DIAm fibers were comparable and significantly higher than mitochondrial volume density in type IIx/IIb fibers (p<0.0001; Tukey’s post hoc test). C. The mean branch length varied across DIAm fiber types (p<0.001; one-way ANOVA). The mean branch lengths of type I and IIa were comparable but significantly longer than those of type IIx/IIb fibers (p<0.0001; Tukey’s post hoc test). D. The MCI varied across DIAm fiber types (p<0.001; one-way ANOVA). The MCIs of type I and IIa were comparable but significantly larger than those of type IIx/IIb fibers (p<0.0001; Tukey’s post hoc test). For each comparison n=15 fibers per type per animal (6 animals – 3 females and 3 males) with females indicated by grey shading. * denotes p< 0.05.
