Early Changes in Costameric and Mitochondrial Protein Expression with Unloading Are Muscle Specific

Table 1

Fiber types in SOL and VL muscle. (a) Mean ± SE of MCSA of type I and type II muscle fibers in SOL and VL muscle, respectively, before ULLS. (b) Mean ± SE of the percentage of type II fibers in both muscles before and after ULLS. Repeated ANOVA with a two-tailed post hoc test of Fisher.

(a)

MCSA type I	[μm^2]
VL	5275 ± 442
SOL	6330 ± 479
value	0.102
MCSA type II	[μm^2]
VL	6225 ± 292
SOL	7353 ± 382
value	0.026

(b)

Type II [%]	Before	After	value (before versus after)
VL	49.3 ± 7.1	57.5 ± 5.7	0.347
SOL	14.2 ± 4.2	17.1 ± 3.9	0.364

value (VL versus SOL) is 0.001.
