Objective：Ｔo investigate the characteristics of cardiovascular autonomic nerve system（ANS） modulation in wrestling and judo athletes comparing with health untrained people. Methods：Thirty-two professional male wrestling and judo athletes（test group） and 32 health untrained male college students（control group） were tested by time domain, frequency domain and nonlinear analysis of short-term heart rate variability（HRV）. Results：By time domain method, the SDNN, RMSSD, SDSD and PNN50 in the athletes were significantly higher than those in health untrained people（P < 0.05）. By frequency domain method, the TP, LF and VLF were statistically higher in the athletes（P < 0.05） than control group. The LF／HF, HF, HFnu and LFnu were slightly higher in the athletes, but the differences didn’t have statistical significance. The results showed that there were significantly higher HRV in wrestling and judo athletes than in untrained people. Conclusion：Compared with the health untrained people，the level of parasympathetic and sympathetic tone were elevated in wrestling and judo athletes.
