Fig. 3. Effect of a combination of moderate and high intensity exercise on muscle glucose 6-phosphate levels during and after exercise. Glucose 6-phosphate levels were determined as described in Materials and methods. M and H refer to values found immediately following moderate and high intensity exercise, respectively. The values are shown as means ± S.E.M. (N=9). The letter a above the bars indicates no significant differences between the values; no letter indicates that this value differs significantly from all others (ANOVA followed by Fisher PLSD a posteriori test; P<0.05).
