Fig. 4. Effect of a combination of moderate and high intensity exercise on the
fractional velocity of glycogen synthase in muscles during and after exercise.
Glycogen synthase fractional velocity is the percentage of the enzyme activity
in the presence of low and high levels of its activator, glucose-6-phosphate.
The fractional velocities of glycogen synthase 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). ac above the points
indicate statistical differences: the same letter indicates no significant
differences between the values; different letters indicate that the values
differ significantly; no letter indicates that this value differs
significantly from all others (ANOVA followed by Fisher PLSD a
posteriori test; P<0.05).
