Fiber type distribution of CnAα−/− skeletal muscle is normal.

<p><b>A)</b> Gastrocnemius muscle samples were fixed and stained with NADH-tetrazolium. Typically appearing type I, IIa/x, and IIb fibers are indicated with arrows on each panel. Data shown are representative of 6 mice per group. <b>B)</b> The distribution of type I, IIa/x, and IIb fibers were quantified and graphed. The data shown are the mean ± SEM of 6 mice per group.
