Fig. 4. Comparison of cross sectional areas of the whole fibre, the core of mitochondria, and the myofilaments between SMR (black) and CMP (white) fibre preparations. The plots illustrate the median (the horizontal line), the upper and lower quartile (the box), and the range of the data (the `whiskers'). There were no outliers. Approximately 40 SMR and 40 CMP fibres were measured from each of five different animals. ^*Significantly different (P<0.001; ANOVA with Tukey HSD post hoc test).
