Abstract: Objective analysis of HRV data and the autonomic nervous system function test results of the relationship that exists between， systematic preliminary study of Tai Chi Chuan training on the impact of the status of autonomic nervous Methods 12 non-sports professionals as a control group of girls， girls 11 Tai Chi Chuan as a special experimental 23 subjects， respectively， in a quiet state， lie down - vertical test stand - lie down under the application of test techniques Holter monitoring for heart rate variability analysis of the frequency Results (1) quiet at the high-frequency components of the experimental group (HF) 15 ~ 40Hz was significantly higher than (2) vertical - back lying lie down when the pilot of the high-frequency components of the experimental group (HF) 15 ~ 40Hz， total power (TP) 00 ~ 40 Hz was significantly higher than (3) the control group and experimental group the results of autonomic nervous system function tests， there was a significant (4) lie down - vertical test of the added value of heart rate and RR interval adjacent to the margin of the square root of mean square (RMSSD)， poor adjacent RR interval> 50ms total number of the percentage of the number of heartbeats (pNN50)， high frequency component (HF) 15 ~ 40Hz， total power (TP) 00 ~ 40 Hz showed a significant negative Vertical - Test Center lie down to reduce the rate of value and high-frequency component (HF) 15 ~ 40Hz were significantly negatively Conclusion Long-term tai chi training will enable the systematic body resting vagal tone Taijiquan special athletes in the supine position to a better state of vagal tone reflects the Taijiquan athletes vagus nerve excitability is higher than the general population， less than sympathetic excitatory general Autonomic function tests and HRV-related indicators to reflect the body's autonomic nervous system function the same Key words: autonomic nervous system; heart rate variability; Taijiquan; upright lie down experiments， upright lie down experiment
