Permeabilised muscle fibre size and contractility: (a) permeabilised fibre cross-sectional area (CSA), (b) maximum isometric force (Fo) and (c) specific force (sFo) of 0 mg/kg, 3 mg/kg, and 10 mg/kg groups. Values are mean and standard error. Differences between groups were tested using a one-way analysis of variance (α = 0.05) followed by Fisher’s Least Significant Difference post hoc sorting. *, significantly different from 0 mg/kg; #, significantly different from 3 mg/kg (p < 0.05).
