![]() ![]() Analyses revealed using adults METs, combined with child resting metabolic rates, as the best existing technique to assign EE to children when measured values are not available. From a practical perspective, The YOUTH-MET may be the more feasible metric for improving of the Compendium of Physical Activities for Youth. The resultant data set (excluding walking and running) contained 5592 data points encompassing 51 activities. YOUTH-MET was better for expressing energy expenditure for sedentary and light activities, whereas allometric scaling was better for moderate and vigorous intensity activities. The Adult MET consistently overestimated EE. No energy expenditure metric completely eliminated the influence of age, physical characteristics, and sex. For sedentary and low-intensity activities, YOUTH-MET was least related to age and sex. For moderate-to-vigorous intensity activities, allometric scaling was least related to age and sex. The Compendium coding scheme links a five-digit code that describes. It was developed to enhance the comparability of results across studies using self-reports of PA. Net and allometric-scaled VO2, and YOUTH-MET were least associated with age, sex and physical characteristics. We provide an updated version of the Compendium of Physical Activities, a coding scheme that classifies specific physical activity (PA) by rate of energy expenditure. These metrics were regressed with age, sex, height, and body mass. Ainsworth Request full-text Abstract Over the past several years, editors Chuck Corbin, Bob Pangrazi, and Don Franks have. Absolute oxygen uptake (ml.min-1), oxygen uptake per kilogram body mass (VO2 in ml.kg-1.min-1), net oxygen uptake (VO2 - resting metabolic rate), allometric scaled oxygen uptake (VO2 in ml.kg-0.75.min-1) and YOUTH-MET (VO2. The Compendium of Physical Activities January 2011 Authors: B. Resting metabolic rate (RMR) was computed based on Schofield Equations. ![]() Such a metric could improve our ability to further advance the Compendium of Physical Activities for Youth.Ī secondary analysis of oxygen uptake (VO2) data obtained from five sites was completed, that included 947 children ages 5 to 18 years, who engaged in 14 different activities. The Compendium of Physical Activities collects information from multiple sources and lists the intensity of these various activities, ranging from playing the piano to driving a tractor to gardening along with a corresponding estimate of the metabolic equivalents (METs) expended. This study examined several common metrics for expressing energy expenditure to determine whether one metric can be used for all healthy children. The updated Compendium reflects additional activities identified by researchers in the past 10 years and presents measured MET intensities for some activities in which METs were estimated from similar activities. Several approaches have been used to express energy expenditure in youth, but no consensus exists as to which best normalizes data for the wide range of ages and body sizes across a range of physical activities. We provide an update of the initial Compendium of Physical Activities, developed in 1989 and published in 1993. ![]()
