Myonuclear domain size, defined as the fiber CSA per nuclei, was maintained in type I (pre: 1409.6±72.5 μm 2 /nuclei; post: 1341.1±61.5 μm 2 /nuclei) and in type II fibres (pre: 1799.6±96.7 μm 2 /nuclei; post: 1987.1±111.8 μm 2 /nuclei), with an increase in the number of nuclei per muscle cross section of type I fibres (pre: 3.9±0.2; post: 4.6±0.2; p<0.05) and a strong trend for an increase in type II fibres (pre: 3.6±0.2; post: 3.9±0.2; p = 0.07) observed with training ( Fig 2A and B ).
