Fatty acids conjugated to carnitine in type I and type II fibers in the low and normal glycogen leg pre and post 60 min of two-legged cycling exercise. (A) palmitoylcarnitine, (B) increase in palmitoylcarnitine vs. initial muscle glycogen content, (C) decanoylcarnitine and (D) propionylcarnitine. Individual values from 5 subjects, except for type II fibers in the low leg pre-exercise (n = 4) and type I fibers in the normal leg post-exercise (n = 4) as well as mean values are presented. In A, C and D, filled circles indicate male subjects and open circles the female subject, however, some values are masked due to overlap. In B circles indicate male subjects and triangles the female subject. Linear mixed effects models were employed to identify differences between legs, fiber type and time
