An observational study of the reliability and concurrent validity of heart rate variability devices in athletes
Both the Polar chest strap and smartphone PPG app demonstrated acceptable reliability and validity for short-duration HRV assessment in athletes. While the chest strap outperformed the PPG app in precision, the PPG app may offers a practical, low-cost alternative for athlete monitoring.
