indirect calorimetry (TrueOne2400; ParvoMedics, Sandy, UT), as well as convective fan cooling (∼3.2 m·s −1 ). Workload increased by 35 W every 3 minutes until the respiratory exchange ratio reached 1.0. Capillary blood samples were obtained in the last 30 seconds of each stage and analyzed for lactate

 = 0.28), with EE which was calculated from DLW by accounting for resting metabolic rate from indirect calorimetry and the thermic effect of food ( Colbert et al., 2011 ). However, objective measures were superior than subjective measurements, including CHAMPS, when assessing PA in older adults

evaluated the relative validity of four competing methods for processing raw accelerometer data from wrist-worn ActiGraph (ActiGraph, LLC, Pensacola, FL) monitors against indirect calorimetry ( Ellingson et al., 2017 ). These four methods represent a range of simple through complex processing methods for

. The activity protocol had been validated against indirect calorimetry and doubly labeled water ( 29 ). EE was calculated using the compendium of physical activities to determine the appropriate MET values for each activity performed ( 1 ). The MET values are multiplication factors of the BMR. In the

Although we cannot say for sure if energy expenditure is affected by wearing a PMU, it would be implausible to conduct the current study with indirect calorimetry, as the traditional metabolic cart is too

. Exercise sessions were isocaloric, with energy expenditure set at 350 kcal (1050 kcal/wk), estimated by indirect calorimetry. Once each participant had a specific and individualized workload, the duration of the exercise sessions differed between adolescents. Based on the metabolic equivalent of task and

Previous work reported that the Harris–Benedict equation is a valid measure of energy expenditure with a minimal difference of 391 kcal/d compared with gas exchange values using indirect calorimetry. 21 Corrected   MET   intensity   =   mean absolute   MET   per activity × ( 3.5 / Harris
