Why the study?
Heart rate variability devices differ in their measurement methods, including timing, pulse versus R waves, and signal processing, leaving the level of agreement between systems unclear.
Does the Polar Nightly Recharge function agree with the Polar H10 chest strap and Kubios app in measuring weekly heart rate variability changes in recreational athletes?
Does the Polar Nightly Recharge function agree with the Polar H10 chest strap and Kubios app in measuring weekly heart rate variability changes in recreational athletes?
Despite good correlation and reliability between the Polar Nightly Recharge and Polar H10 chest strap with Kubios app, there is significant discordance in the interpretation of weekly HRV changes, suggesting they should not be used interchangeably.
