Comparative evaluation of heart rate-based monitors: Apple Watch vs Fitbit Charge HR
TLDR
The Apple Watch 1 had stronger validity than the Fitbit Charge HR for assessing overall EE and steps during aerobic exercise and heart rate estimates that were statistically equivalent to Polar monitor.Abstract:
The purpose of this investigation was to examine the validity of energy expenditure (EE), steps, and heart rate measured with the Apple Watch 1 and Fitbit Charge HR. Thirty-nine healthy adults wore...read more

Accuracy of Consumer Wearable Heart Rate Measurement During an Ecologically Valid 24-Hour Period: Intraindividual Validation Study
TL;DR: Preliminary support is provided that these devices appear to be useful for implementing ambulatory measurement of cardiac activity in research studies, especially those where the specific advantages of these methods are particularly suited to the population or research question.
Journal ArticleDOI
Validation of the Apple Watch for Heart Rate Variability Measurements during Relax and Mental Stress in Healthy Subjects
TL;DR: HRV indices derived from the Apple Watch RR interval series were able to reflect changes induced by a mild mental stress, showing a significant decrease of HF power as well as RMSSD in stress with respect to relax, suggesting the potential use of HRV measurements derived from Apple Watch for stress monitoring.

Using Pedometers to Increase Physical Activity and Improve Health: A Systematic Review
Dena M. Bravata,Crystal Smith-Spangler,Vandana Sundaram,Allison Gienger,Nan Lin,Robyn Lewis,Christopher D Stave,Ingram Olkin,John R. Sirard +8 more
TL;DR: The results suggest that the use of a pedometer is associated with significant increases in physical activity and significant decreases in body mass index and blood pressure.

Validity of 10 electronic pedometers for measuring steps, distance, and energy cost.
TL;DR: In general, pedometers are most accurate for assessing steps, less accurate for assessing distance, and even less accurately for assessing kilocalories.

Juul Achten,Asker E. Jeukendrup +1 more
TL;DR: There appears to be a small day-to-day variability in HR and a steady increase during exercise has been observed in most studies, and the effects of overreaching on submaximal HR are controversial, with some studies showing decreased rates and others no difference.

Pedometer measures of free-living physical activity: comparison of 13 models.
TL;DR: The KZ, YX200,NL, NL, and YX701 appear to be suitable for most research purposes, and it is necessary that there be consistency across studies in the measurement of "steps per day."

Reliability and validity of the combined heart rate and movement sensor actiheart
TL;DR: The Actiheart is technically reliable and valid but further studies are needed to assess validity in other activities and during free-living.
