I am hoping to estimate energy expenditure (kJ or calories) from actigraph reported movement behaviors (i.e. LPA, MVPA, SB) in minutes, for children age 8-12 years. The data was collected with the Actigraph wGTX3-BT for 24 hours a day for 7 nights, children only removed the actigraph for water based activities. The Actigraph was initialized using 15-second epochs.
