2.6. Physical Activity Monitoring
Physical activity levels were assessed using an ActiGraph wGT3X-BT accelerometer (ActiGraph, LLC Pensacola, FL, USA). Participants wore the SenseWear armband on their dominant wrist for one week at each study timepoint. Only days when the armband was worn for ≥12 h were used in analysis. Physical activity data was assessed using ActiLife software to provide time (minutes) spent sedentary and time in light, moderate, and vigorous intensity physical activities. In addition, total active time, percent of each day active, step counts per day, physical activity metabolic equivalents (METs), and energy (kcal) expended during physical activity were calculated.
