From: Carnitine supplementation to obese Zucker rats prevents obesity-induced type I to type II muscle fiber transition and favors an oxidative phenotype of skeletal muscle

Figure 1

Fiber distribution of M. rectus femoris of lean rats (lean control), Zucker rats fed a control diet (obese control) or Zucker rats fed a diet supplemented with 3 g/kg diet carnitine (obese carnitine) for 4 wk. (A) muscle fiber type composition, (B) fiber type-specific cross-sectional area, (C) relative mRNA expression of myosine heavy chain isoforms. Bars represent means ± SEM, n = 12 rats/group. Means without a common letter differ (P < 0.05).
