examined validity in controlled and semi-structured lab settings ( Evenson, Goto, & Furberg, 2015 ). An advantage of these settings is that it enables the use of more robust criterion measures such as portable, indirect calorimetry systems. However, results vary widely based on the nature of activities

Three studies have compared the AP inclinometer function to AG count-based estimates of SB in youth, and have found

Ventilatory thresholds (VT1 and VT2), 7 , 8 maximum HR (HR max ), VO 2 max, and PPO were determined from the maximal cycle exercise test. VT1 and VT2 were determined by

Substrate oxidation rates were calculated using indirect calorimetry (Quark CPET; COSMED, Rome, Italy). 5 The submaximal test and TTs were performed in the laboratory using his own bicycle mounted
