  1. 1 See Table 2 for the number of fibre types analysed in each skeletal muscle
  2. CSA (μm2), and absolute (n) and relative (n 103/μm2) numbers of both capillaries and nuclei of the different fibre types in each of the two studied muscles are shown. Relative values are obtained by dividing the absolute values by the CSA. Post hoc comparisons of means were provided by a Fisher's least significance difference test. Means with different letters are statistically different.
