In fact, while BI-index is strictly related to FFM, PhA is thought to be a proxy of both water distribution (i.e. In comparison to the direct calorimetry, the method is more affordable, and presents the advantage of providing information on the metabolic fuels being combusted in addition to measuring the metabolic rate [39]. Bias was found acceptable if within 5% [32, 33]. One of the questions that have been raised with the development of new generations of accelerometers is the comparability between their output and the previous generations. Details on these questionnaires are provided elsewhere [93]. Exercise is a subset of physical activity that is planned, structured, and repetitive and has as a final or an intermediate objective the improvement or maintenance of physical fitness. https://doi.org/10.1093/ajcn/47.4.591. WHO defines physical activity as any bodily movement produced by skeletal muscles that requires energy expenditure. Measurement conditions for by indirect calorimetry were defined following the suggestions made by Compher et al. REE was directly correlated with individual characteristics, except for age, and raw BIA variables. PubMed Am J Clin Nutr.

Accuracy of prediction equations for measurements of resting energy expenditure within 10%. Objective measurement of physical activity. FOIA One pound of body fat is approximately 3,500 kcal and 1 kg is 7,700 kcal. Their findings indicated that current accelerometer prediction equations have many limitations when translating accelerometer counts to energy expenditure, especially when used across a range of various activities. Description of methods Energy expenditure can be measured using one of the three . De Lorenzo formula [15] was derived in a sample of 51 male athletes (22 water polo, 12 judo, 17 karate) who exercised at least 3h/day; in that paper REE was underestimated by most of the seven equations selected from the literature. Coefficient of determination (R2) and standard error of the estimate (SEE) were considered for assessing the predictive power of formulas. Linear correlation was applied for evaluating associations between variables. Introduction.

From a practical point of view, evaluating the accuracy of predictive equations at individual level (within 10%) is crucial for the nutritional management of the single athlete. Thus, high PhA indicates greater cellularity (e.g. Studies have reported electrical or magnetic interference with the heart rate measurements by devices such as computers, microwaves, televisions, and motorized exercise equipment, leading to unstable readings and data loss [72]. Direct animal calorimetry, the underused gold standard for quantifying the fire of life. Not surprisingly, the results of these studies suggest that raw BIA variables may improve the prediction power under physiological conditions [24], but only to a limited extent in subjects with altered body water distribution [25, 26]. Provide information on physical activity patterns. Estimation of free-living energy expenditure by heart rate and movement sensing: a doubly-labelled water study. 2015;16:314. Interestingly, raw BIA variables such as bioimpedance index (BI-Index=stature2/impedance at 50kHz) and phase angle (PhA) might be taken into account as possible predictors of REE. Bethesda, MD 20894, Web Policies Total energy expenditure of 16 Chinese young men measured by the doubly labeled water method. Prior to the administration, the DLW can be sterilized by pushing it through a 0.22 m filter. Studies have established that heart rate changes proportionally with activity intensity and oxygen consumption in moderate to vigorous physical activities [69]. What is Energy Expenditure?

Some authors also introduced FFM as predictor, with no increase in the prediction power [17, 18]. In this perspective, bioelectrical impedance analysis (BIA) is widely used for assessing body composition in athletes [20], but the interpretation of BIA results depends to a large extent on the equation used to estimate FFM [21]. On the contrary, BI-index was not recognized as a stronger predictor than weight, possibly because of low body fat percentage and low BMI. Provides information on the metabolic fuels being combusted. Two of the existing formulas for athletes identified also stature as predictor [15, 17] while in the athletes we studied, REE was correlated to stature in univariate analysis, but not in multiple regression analysis, p=0.374).

Bland - Altman plots between differences and mean predicted-measured resting energy expenditure using new equations. Also, the inter-day CV (as determined in 10 subjects on subsequent days) was always less than 4%. Since physical activity records and diaries require participants to record performed activities, they minimize the memory bias in case they are completed on time. Some of equations permit to calculate energy expenditure as metabolic equivalents (METs) [58,59,60] or kcal/min [60,61]. https://doi.org/10.1249/MSS.0000000000000852. When one exceeds the other you will lose or gain weight. A reappraisal of the caloric requirements of men. In other studies, it has served as a reference method to assess the accuracy of other methods of energy expenditure measurement, such as the validation of accelerometers [52] or predictive equations for REE [53,54]. More recently, attention has been focused on the role of PhA as a biomarker of body cell mass and muscle quality as well as of water distribution (ratio between extracellular water-ECW and intracellular water-ICW) [22]. Heart rate monitors are among commonly used objective tools for measuring physical activity and energy expenditure [66,67]. In case of REE calculation, the abbreviated Weir's formula [48,49] is mostly used: Indirect calorimetry is the most widely used method to assess energy balance, including those involving patients in clinical setting [50,51]. 2021;13(5):1620. https://doi.org/10.3390/nu13051620. 1988;47(4):591607. One of these factors is exercise economy, defined as the amount of energy spent per unit of velocity (di Prampero, 2003), and there have been reports of close relationships between exercise economy and performance in several endurance sports (Conley and Krahenbuhl, 1980; Saunders . Of note, Malaysian population seemed to have relatively low body frames and size and, therefore, low REE [16]. Physical activity assessments for health-related research. 2014;9:e108460. Examples: 4 METS (Used by Surgical Risk Evaluation) [1] Instead of using BIA-derived body composition (strictly dependent on the BIA formula used), we opted for including raw BIA variables (BI-index and PhA) in the regression model (Model 2, Eq. Cite this article. Precision accuracy (individual predicted-measured differences within 5%) was ~75% in six out of eight of the selected equations and even higher for Eq. 2020;44(6):10218. Data for impedance and PhA from the non-dominant side of the body, measured at 50kHz, were considered. Best practice methods to apply to measurement of resting metabolic rate in adults: a systematic review.
