EDL, extensor digitorum longus; CSA, cross-sectional area; Lo, optimal length.

Female significantly different from age- and strain-matched male.

^†

mdx is significantly different from BL10 within the same gender.

^‡

Twenty-month-old group is significantly different from 6-month-old group within the same gender and strain.
