2.9. Physical Activity
Participants were fitted with a waist-worn triaxial accelerometer (ActiGraph wGT3X-BT, LLC, Pensacola, FL, USA) using an elastic belt to secure above the right hip bone to measure their movements and activities for at least 7 days prior to each metabolic testing. The monitor was initialized at a sample rate of 30 Hz to record activities for free-living conditions. ActiGraph data were downloaded and analysed by using ActiLife 6 software after collecting the devices from participants.
