What did studies of axivity AX3 find?

2

Studies of axivity AX3 measured 2 outcomes; the most studied are sleep duration (1 study) and Average Acceleration (1).

Sleep duration

no changein humans1

1 study

  1. Axivity AX3 showed no clear effect on sleep duration in humans (British and Chinese adults; comparison with Matrix 003) (Equivalent within a ±10% equivalence zone).

    “In both British and Chinese adults, average acceleration, sedentary time, time in bed, and sleep duration were equivalent between the two accelerometers”

What is axivity AX3 linked with?

1

Studies link axivity AX3 with 1 measure, most often time in moderate-vigorous physical activity (1 study).

Wrist trackers gave comparable overall activity readings

An observational comparison in 85 British and 117 Chinese adults aged 50 or older found comparable overall movement readings over up to eight days.An observational comparison in 85 British and 117 Chinese adults aged 50 or older found comparable overall movement readings over up to eight days.
