PURPOSE: The purpose of this study is to examine the effect of resting heart rate variability on shooting performance among rapid fire pistol athletes. METHODS: Twenty-four elite shooting athletes, who have more than two years of rapid tire pistol, were divided into higher and lower groups based on their record of current five shots was 570.7, and the average score of the lower group was 548.58. Heart rate variability were measured two times from all participants for two mins thirty seconds. uBioMacpa version 1.0 was used to measure heart rate variability from their index finger, which saved automatically into a computer. Using SPSS 20.0, the data was analyzed by a independent t-test, Pearson r, and multiple regression. RESULTS: The elite shooting athletes in the higher group were significantly lower in TP, LF, HF, SDNN, and RMSSD than the lower group. The correlation between the shooting performance and SDNN was 436, and SDNN predicted 19% in the variance of shooting performance. CONCLUSIONS: It is concluded that heart rate variability may be a important index to understand the condition of elite shooting athletes.
