Key result
Zephyr Bioharness and Fitbit Charge demonstrate excellent reliability for heart rate and activity measures.
Why the study?
The reliability of Zephyr Bioharness and Fitbit Charge devices for measuring heart rate and activity at rest, during submaximal fitness testing, and recovery was not established.
Do Zephyr Bioharness and Fitbit Charge devices provide reliable measures of heart rate and activity in healthy adults at rest, during exercise, and recovery?
Cross-Sectional (n=60)
No

Supports wearable HR monitoring in healthy adults for research; leaves open validation before clinical adoption.
Nazari et al. (2017) conducted a cross-sectional in Healthy (n=60). Zephyr Bioharness and Fitbit Charge was evaluated on Intrasession and intersession reliability of heart rate and activity. Zephyr Bioharness and Fitbit Charge devices demonstrated excellent reliability for heart rate and activity measures across all phases, with intersession ICCs ranging from 0.76 to 0.98.
