2.6. Accelerometer
movement behaviors
The participants were asked to wear an accelerometer (Actigraph wGT3X-BT Monitor, Actigraph LLC, Pensacola, FL, USA) for the entire study period (14 consecutive days and nights) to record 24 h physical activity measurements. This information was collected to determine the overall physical activity and movement behaviors (including activity intensity). The participants wore the accelerometer on their waist during the day and on a wrist strap at night. Data were downloaded onto specific software (ActiLife 6, Actigraph LLC) and analyzed for activity levels.The data collected were used to evaluate the durations (summed durations of accelerations) and intensity (magnitude of accelerations) of their physical activity and the caloric expenditure throughout the waking wear time [
