Abstract— The aim of the study is to quantify the alteration in the autonomic nervous system (ANS) function of professional shooting athletes before, during and after the match and examine whether some indices reflecting the activity of the ANS are related to their sports capacity and performance. Seven male professional shooters with various sports capacity participated in the study. Heart rate variability (HRV) signals of each subject under three situations (rest, match and postmatch) were collected by a one-channel recorder. Then a method of fast Fourier transform was used to calculate the power spectra of different frequency bands for all the data. The average heart rate (HRAve), and three frequency-domain parameters: normalized low frequency component (LFnorm), normalized high frequency component (HFnorm) and the ratio of low frequency component to high frequency (LF/HF) were evaluated. The results show that at rest, HRAve is 66±7 beats/min, LFnorm is 47.46±8.38 nu, HFnorm is 46.96±10.26 nu and LF/HF is 1.33±0.58; and during the match, HRAve is 82±12 beats/min, LFnorm is 73.74±13.55 nu, HFnorm is 24.55±13.97 nu and LF/HF is 5.73±4.59. The differences of all the measures between rest and match are statistically significant (t test, P
