Fig. 3. The effect of repeated high-intensity exercise and recovery on glucose and lactate levels in the plasma. On the x-axis, E refers to exercise and Rec to recovery. The values shown represent means ± S.E.M. (N=8). Identical superscripts on different columns indicate the absence of significant differences, whereas columns without a superscript differ significantly from any column bearing a superscript (ANOVA followed by Fisher PLSD a posteriori test; P<0.05).
