OBJECTIVE: By comparing the differences in pre-competition state anxiety, inter-competition heart rate variability (HRV), and shooting performance of young athletes of different grades, and revealing the correlation between these variables, it provides a potential basis for improving athletes' shooting performance. METHODS: A total of 45 adolescent shooters were selected in Chongqing, China, and completed 40 effective shots at self-pace in real shooting scenes. The pre-competition state anxiety, inter-competition HRV, and shooting performance of the athletes were monitored and evaluated respectively. RESULTS: (1) There was a significant difference in the pre-match state anxiety of the adolescent shooters, which showed that the cognitive state anxiety and physical state anxiety of the first-level athletes were significantly lower than those of the second-level athletes, while the state confidence was significantly higher than that of the second-level athletes. (2) There were significant differences in HRV of athletes with different sports levels during the competition, showing that the root mean square differences of the standard deviation (RMSSD), total power (TP), and high-frequency of normal (HFn) of the first-level athletes were significantly higher than those of second-level athletes, while low-frequency of normal (LFn) was significantly lower than the latter. (3) The shooting performance of first-level athletes was significantly better than that of second-level athletes....
