Visualization of PA counts per minute (A) and PA bouts (B) over three hours. PA = physical activity; MVPA = moderate to vigorous physical activity. A) The two lines (at 100 and 1952 counts) reflect the cut-points for light activity and MVPA. Values ≤ 100 correspond to sedentary PA, values between 100–1951 to light PA and ≥ 1952 to MVPA . B) 1-minute-bout.
