Table 1 Classification of physical activity intensity based on Evenson accelerometer cut-off points and MET thresholds[18]

From: The intensity of physical activity influences bone mineral accrual in childhood: the childhood health, activity and motor performance school (the CHAMPS) study, Denmark

Physical activity intensity

Accelerometer cut points

Units of metabolic equivalent (MET)

Sedentary activity

≤ 100 counts/min

METs < 1.5

Light physical activity

> 100 counts/min

1.5 ≤ METs < 4

Moderate physical activity

≥ 2296 counts/min

4 ≤ METs < 6

Vigorous physical activity

≥ 4012 counts/min

METs ≥ 6
