Objective Investigate the characteristics of heart rate variability of the taekwondo and the college students.Methods MCA-3C heart function detector was used to collect the 512 times heart rate information of the students in a state of quiet backlying and the information on time and frequency domain of heart rate variability were analyzed.Results The value of time-domain indexes(HRP,RRP,RRM,RRN,SD,MSD,P50) of experimental group were significantly higher than the control group(P0.01);The value of frequency domain indexes(TS,HF.H,HF.A,HF.S,LF/HF) were also higher than the value of control group(P0.01);other indexes are also higher,but no statistical significance.Conclusion Compare with college students,the heart rate variability of Taekwondo students is larger,the vagal tone is relatively large and sympathetic tone is relatively low,the regulation ability of autonomic nervous system is more strong.
