From: Sympathetic modulation of hindlimb muscle contractility is altered in aged rats
Effect of LST stimulation on the TF of the triceps surae muscles. (A) Example responses in each one young and aged rat of the TF before and during LST stimulation at 10 Hz. See Fig. 1A for further details. (B) Graph summarizing (n = 11 rats for each group) the changes in the amplitude of the TF expressed as the percent change of the control TF without LST stimulation. X axis: frequency of LST stimulation. Y axis: changes in the peak amplitude of the TF during LST stimulation, expressed as a percentage of the control TF just before LST stimulation. *P < 0.05, **P < 0.01 (paired t-test, compared with the control TF without LST stimulation).
