Morphological analysis of fibre type composition (total type I fibres and total type II fibres) and cross-sectional area (CSA) defined as “small-sized fibres” (CSA 0–2999 μm²), “normal-size fibres” (CSA 3000–9900 μm²), and “large-sized fibres” (CSA > 10.000 μm²). a denotes differences from baseline and b denotes difference from pre; < 0.05.
