Effects of Biofeedback Training on Shooters' Performance, Stress Levels, and HRV

This study aimed to explore the impact of a 12-week biofeedback training on shooters' performance, stress levels, and heart rate variability (HRV). Thirty-six shooters aged 18-24 (18 subjects in each group) participated. The experimental group underwent 12 weeks of biofeedback and shooting training, while the control group only received shooting training. Results showed significant improvements in performance, stress levels, and HRV parameters in the experimental group, reflecting enhanced parasympathetic activity. It was further revealed that TP value was negatively correlated with stress level and positively correlated with performance, and stress level was negatively correlated with performance.
