Fiber type dependent average interfiber distance

	Young	Old
Type I	265.6 ± 9.4	257.0 ± 10.1
Type IIa	248.2 ± 9.0^†	245.6 ± 9.6^†
Type IIx and/or IIb	233.8 ± 9.1^†	216.6 ± 10.0^†

Average interfiber distance (µm) was analyzed with a mixed linear model with an individual animal as a random effect (age × fiber type × animal; interaction P=0.005), data are presented as least squared mean ± standard error.

significantly different than type I fibers of same age group.
