Polar H10 showed to be the most accurate wearable device in 24-hour heart rate variability measurement in military

30/11/2021

Heart rate variability (HRV) measurements provide information on the autonomic nervous system and the balance between parasympathetic and sympathetic activity. A high HRV can be advantageous as it reflects the ability of the autonomic nervous system to adapt. On the contrary, low HRV can indicate fatigue, overtraining, or health issues.

In recent times, there has been a surge in wearable devices that claim to measure HRV. Some devices include spot measurements, whilst others only record during periods of rest and/or sleep. Few devices, however, are capable of continuously measuring HRV (≥24 h).

This study presents a database search review of the literature with the aim to determine which of the currently available wearable devices are capable of measuring continuous, precise HRV measures. The review also evaluates which devices are the most suitable in a field setting specific to military populations.

Authors conclude that the Polar H10 appears to be the most accurate wearable device when compared to criterion measures, and even appears to supersede traditional methods during exercise. However, currently, Polar H10 must be paired with a watch to export the raw data for HRV analysis.
