  1. Total SED minutes: the total number of minutes spent in sedentary activity (defined as all minutes with an average activity count of < 100 counts•minute-1)
  2. Total time spent in SED bouts of ≥30 min: the total number of minutes spent in sedentary activity in a sedentary bout lasting ≥30 min. A sedentary bout is defined as ≥1 consecutive minutes with < 100 counts•minute-1
  3. Total # of breaks in time spent in SED bouts of ≥30 min: the total number of interruptions (i.e., accelerometer counts per minute were ≥ 100) in sedentary time lasting ≥1 min in a sedentary bout lasting ≥30 min
  4. Total # of MVPA bouts of ≥10 min: the total number of bouts spent in MVPA lasting ≥10 min. A MVPA bout is defined as ≥10 consecutive minutes with ≥1952 counts•minute-1
