Muscle fiber cross-sectional area.

<p>Values are means ± SEM <b>a.</b> Total cross-sectional area (CSA) in the plantarflexor. <b>b.</b> Mean muscle fiber CSA in the plantarflexor. <b>c.</b> Percentages of muscle fiber types in the plantarflexor. <b>d.</b> Type IIA muscle fiber CSA in the plantarflexor. <b>e.</b> Type IIB muscle fiber CSA in the plantarflexor muscle. <b>f.</b> Type IIX muscle fiber CSA in the plantarflexor muscle. <b>g.</b> Type I muscle fiber CSA in the plantarflexor muscle. <b>h.</b> Satellite cell composition in the plantarflexor muscle. There were no significant differences between groups for any of the measures.
