Fig. 3

The mean heart rate for all subjects during rest, and 0–20, 20–40, and 40–60 s of high- (A) or low-intensity exercise (B) during two experimental tasks. All data represent changes from baseline resting values. In the high-intensity exercise condition, ANOVA revealed a significant main effect of stimulation (F(1, 9) = 14.3, p = 0.004) and condition (F(3, 27) = 436.2, p < 0.001) on heart rate. However, there were no significant stimulation x condition interaction effects. In the low-intensity exercise condition, ANOVA revealed a significant main effect of stimulation (F(1, 10) = 13.9, p = 0.004) and condition (F(3, 30) = 745.2, p < 0.001) on heart rate. However, there were no significant stimulation x condition interaction effects. Data are the mean ± standard deviation. *p < 0.05 significant difference between acupuncture stimulation and no-stimulation tasks
