PURPOSE The accurate estimative of energy needs is crucial for an optimal physical performance among athletes and the basal metabolic rate (BMR) equations often are not well adjusted for adolescent athletes requiring the use of specific methods, such as the golden standard indirect calorimetry (IC). Therefore, we had the aim to analyse the agreement between the BMR of adolescents pentathletes m...

BACKGROUND The purpose of this investigation was to identify the onset of the thermic effect of feeding (TEF) after ingestion of a high carbohydrate (CHO) and a high protein (PRO) 1255 kJ (300 kcal) drink. METHODS Resting metabolic rate (RMR) and TEF were measured over 30-minute periods via indirect calorimetry using a ventilated hood technique. Eighteen subjects (7 men and 11 women) complete...

BACKGROUND As part of a comprehensive occupational medical program for fire departments in the USA, the National Fire Protection Association and The Fire Service Joint Labor Management Wellness/Fitness Initiative endorse a standardized submaximal test that uses the Gerkin treadmill protocol for predicting the maximal oxygen uptake (VO(2max)) of firefighters. AIMS To test the validity of the G...

Purpose. To critically review the validity of accelerometry-based prediction models to estimate activity energy expenditure (AEE) in children and adolescents. Methods. The CINAHL, EMBASE, PsycINFO, and PubMed/MEDLINE databases were searched. Inclusion criteria were development or validation of an accelerometer-based prediction model for the estimation of AEE in healthy children or adolescents (...

The NE content of diets containing wheat-corn distillers dried grains with solubles (wcDDGS; 1:1 ratio) fed to growing pigs was determined using the comparative slaughter (CS), indirect calorimetry (IC), and chemical composition (CH) methods. The experimental diets were a corn-soybean meal control diet (CTRL), CTRL + 15% wcDDGS, and CTRL + 30% wcDDGS. In Exp. 1, 56 barrows (18.5 kg BW) were use...

INTRODUCTION The determination of energy expenditure, considering the physical activity level and health status, is very important to adjust the individuals' nutritional supply. Energy expenditure can be determined by using indirect calorimetry, bioelectrical impedance, doubly labeled water, predictive equations, among others. All these methods have been used in clinical and research areas. How...

OBJECTIVE To measure BMR in a probability sample of adults from an urban city of Brazil and to compare indirectly measured BMR (BMRi) with BMR predicted from different equations. DESIGN BMR data were obtained by indirect calorimetry and estimated by different predictive equations (Schofield; Harris and Benedict; Henry and Rees). Anthropometric and body composition measures were also obtained....

Unfortunately, the original version of this article [1] contained an error. The corresponding author’s family name and given name were not included correctly and were inverted with given name being ‘Martin Sundström’ and family name being ‘Rehal’. The names are included correctly here, where ‘Martin’ is the given name and ‘Sundström Rehal’ is the family name. This will be corrected in the origi...

This paper quantifies maximal fluxes through the pathway supplying carbohydrates to the mitochondria of muscle cells. Continuous infusions of D-[3-(3)H]glucose together with indirect calorimetry were used to investigate the partitioning of the supply of carbohydrates through the two branches of the pathway: from circulating glucose and from glycogen stores within the muscle cells to the mitocho...

1 Meal-Induced Thermogenesis (MIT) research findings are highly inconsistent, in part, due to 2 the variety of durations and protocols used to measure MIT. We aimed to determine: 1) the 3 proportion of a 6 h MIT response completed at 3, 4 and 5 h; 2) the associations between the 4 shorter durations and the 6 h measure; 3) whether shorter durations improved the 5 reproducibility of the measureme...
