Quantitative EM analyses of n./area, orientation, and morphology of CRUs in EDL muscles from mice. Note: data in parenthesis are from Pietrangelo et al., 2015.

	A	B	C	D
	No. of CRUs/100 μm²	% of Oblique CRUs	% of Longitudinal CRUs	% of Dyads
Aged	(74.1 ± 1.1)	(8.7 ± 0.8)	(0.9 ± 0.2)	(4.0 ± 0.4)
Aged-trained	85.5 ± 2.0*	5.1 ± 0.7*	0.7 ± 0.3	0.6 ± 0.4*

Data are shown as mean ± SEM (*p < 0.01).

Samples size: 50 fibers from 5 aged mice, 50 fibers from 5 aged-trained mice; Columns A, C and D: 10 micrographs/fiber; Column B: 2 micrographs/fiber (low magnification images in transversal sections).
