Figure 3. — Time course of force decline and recovery in rat EDL during 60 Hz direct stimulation in buffer or in air. Experimental conditions as described in the legend to Fig. 2, but muscles were stimulated continuously for 30 s, followed by 0.5-s trains of 0.2-ms pulses of 60 Hz at the indicated intervals. The muscles were either stimulated in K.R. buffer (filled symbols) or in air, after the buffer had been aspirated (open symbols). Each point represents the mean of observations on four muscles with bars denoting SEM. None of the differences between force development in buffer or in air reached statistical significance.
