reference. 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

Future work could expand upon these findings by examining additive or sustained effects of LPA throughout a day. Another limitation to this study was the use of a controlled laboratory

measurements were performed within 12 min. Jockeys were then required to have RMR measured in a supine position using indirect calorimetry (Metalyser, Thatcham, UK). Jockeys were required to lie down for an initial 15 min before testing to allow for the dissipation of movement from the dual-energy X

of individuals, Lepp et al ( 24 ) demonstrated an inverse relationship between cell phone use and cardiorespiratory fitness by indirect calorimetry. In the same study, high-frequency cell phone users reported greater participation in sedentary activities and fewer physical activities than their low

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

Protocol ( Nana et al., 2015 ). Resting metabolic rate was assessed via indirect calorimetry (GEM Open Circuit Indirect Calorimeter; GEMNutrition Ltd., Warrington, UK) using the protocol described by Bone and Burke ( 2018 ). Peak oxygen uptake was assessed on a motorized treadmill (h/p/cosmos; Pulsar
