Based on the metabolic equivalent of task and considering that for each liter of oxygen (O 2 ) consumed the EE is approximately 4.96 kcal

indirect calorimetry and posture (75 participants, 48 with data from both visits), both of the youth Sojourn models had excellent sensitivity for predicting moderate-to-vigorous PA (95.3% ± 14.3% for the hip, and 94.2% ± 5.4% for the non-dominant wrist). The non-dominant wrist also had sensitivity above 80

 hours and to remain normally hydrated prior to body composition and RMR assessment. After DXA scanning, subjects underwent testing for resting metabolic rate (RMR) via indirect calorimetry to determine daily resting caloric expenditure. Subjects sat quietly in a reclined position and breathed normally

collected continuously throughout the test using an open-circuit indirect calorimetry system (TrueOne 2400 Parvo Medics, Sandy, UT), which was calibrated prior to each test. The test began at a speed between 9 and 12 km·h −1 , based on each athlete’s recent 20-km race performance. All participants were
