This global study analyzed data from the largest dataset ever studied in the Heart Rate Variability (HRV) biofeedback field, comprising 1.8 million user sessions collected from users of a mobile app during 2019 and 2020. We focused on HRV Coherence, which is linked to improved emotional stability and cognitive function. Positive emotions reported by users were associated with higher Coherence scores and more stable HRV frequencies.
This study aimed to explore the impact of a 12-week emWave pro-based heart rate variability biofeedback training followed by a 2-week follow-up on athlete performance, stress levels, and heart rate variability (HRV). Thirty-six athletes aged 18-24 (18 experimental, 18 control) 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. Biofeedback reduced training and competition stress, improving overall performance and stability during matches, emphasizing its effectiveness in shooter training.
