Fig. 3

Levels of substrates and metabolites in type I and type II fibers in the low and normal glycogen leg pre-exercise on day 2. (A) muscle glycogen, (B) glucose-6-phosphate, (C) fructose-6-phosphate, (D) acetylcarnitine, and (E) carnitine. Individual values from 5 subjects as well as mean values are presented, except for type II fibers in the low leg pre-exercise and type I fibers in the normal leg post exercise where n = 4 in figures B to E. Filled circles indicate male subjects and open circles the female subject, however, some values are masked due to overlap. A 3-way ANOVA was employed (A) or linear mixed effects models for variables with missing values (B-E) to compare levels in the low and normal leg as well as between fiber types
