Figure 3 Responses are shown before (–20 s) and that obtained immediately (0 s; peak flow) and 20, 40, 60, 80, 100, 120, 140 and 160 s following 5 min of upper arm ischemia. Top panel shows responses expressed as absolute forearm blood flow; bottom panel as % increase in basal forearm blood flow. Analysis was by two-way repeated measures (RM) ANOVA followed by Student-Newman-Keuls test (*p < 0.05 when compared to control point). Results are expressed as mean ± standard error of the mean.
