Fibre typing in tibialis anterior muscles from 5‐month‐old WT and KI‐Dnm2 ^R465W mice

	WT	KI
Type I	0.33 ± 0.09	0.23 ± 0.09
Type IIa	9.42 ± 0.77	7.79 ± 2.63
Type IIb	90.25 ± 0.69	91.98 ± 2.67

Type I, IIa and IIb muscle fibres were counted after co‐immunostaining of the three corresponding myosin isoforms on tibialis anterior sections. Values are indicated as the percentage of each fibre type relative to the total number of fibres (mean ± SD from four animals per genotype). Statistical analysis was performed using a Mann–Whitney U test (WT vs. KI for each fibre type). None of the mean values differed between the two groups (P > 0.05).
