This study was the examination of the sustained effects of the autonomic nerve response due to the difference in the posture of the supine and the standing after the acupuncture method of the "skin / subcutaneous tissue, exhalation phase, sitting position". The subjects were 11 healthy male college students without medication and smoking habits (age 19.6 ± 1.0 years old, height 172.1 ± 4.1 cm, body weight 70.4 ± 4.3 kg). Cardiac autonomic nerve function was measured by measuring electrocardiogram and analyzing by spectral analysis of heart rate variability. In the evaluation by spectral analysis, the high frequency component HF (0.15 - 0.40 Hz) and the low frequency component LF (0.04 - 0.15 Hz) were measured, and HF component was used as a cardiac parasympathetic function and LF / HF component was used as an index of cardiac sympathetic function. HR and HF components showed no significant change at standing posture with passage of time after the acupuncture stimulation. However, HR and HF components showed significant change at supine posture with passage of time after the acupuncture stimulation, and enhanced the cardiac parasympathetic function. Furthermore, significant increase of LF / HF component was observed between 5 minutes and 25 minutes after the stimulation in the supine position. From these results, it was obvious that the sustained effects of acupuncture stimulation in the enhancement of cardiac parasympathetic function was caused by supine posture. Moreover, it was suggested that this acupuncture method may be enhance both cardiac parasympathetic and sympathetic nerves.
