OBJECTIVE To measure total energy expenditure and body composition in small for gestational age (SGA) infants, to investigate hypermetabolism. METHODS A cross-sectional study was performed in 52 small for gestational age (SGA) measured at 5 weeks of age, using existing data from appropriate for gestational age (AGA) infants as controls. The doubly-labelled water technique was used to assess b...

The aims of the present study were to examine possible effects of age and sex on energy expenditure independent of differences in body composition, and to develop prediction equations for individual estimation of energy expenditure. The study is based on 235 female and 78 male subjects ranging in age from 15 to 64 y and with body mass indexes (in kg/rn2) ranging from 16.9 to 50.5. Basal metabol...

The paper presents two prototypes for the estimation of human energy expenditure during normal daily activities and exercise. The first prototype employs two dedicated inertial sensors attached to the user’s chest and thigh and a heart rate monitor. The second prototype uses only the accelerometer embedded in a smart phone carried in the user’s pocket. Both systems use machine learning for the ...

BACKGROUND Previous studies have demonstrated an association between physical inactivity and hypertension, but the methods used to assess activity have been subjective and imprecise. Recently methods have become available allowing measurement of energy expenditure in free-living populations. Our aim was to employ these methods to assess the independent association between energy expenditure, ca...

OBJECTIVE To evaluate the physiologic responses and energy expenditure of active video gaming using Kinect for the Xbox 360. DESIGN Comparison study. SETTING Kirkby Sports College Centre for Learning, Liverpool, England. PARTICIPANTS Eighteen schoolchildren (10 boys and 8 girls) aged 11 to 15 years. MAIN EXPOSURE A comparison of a traditional sedentary video game and 2 Kinect activity-p...

The aims of this study were to quantify the effects of factors such as mode of exercise, body composition and training on the relationship between heart rate and physical activity energy expenditure (measured in kJ x min(-1)) and to develop prediction equations for energy expenditure from heart rate. Regularly exercising individuals (n = 115; age 18-45 years, body mass 47-120 kg) underwent a te...

Physical activity is defined as any bodily movement produced by skeletal muscles that results in energy expenditure. The benefits of physical activity for health maintenance have been well documented, especially in the prevention and management of chronic diseases. Therefore, accurate measurement of physical activity and energy expenditure is essential both for epidemiological studies and in th...

Background and Objectives: Energy expenditure (EE) is the total energy cost of maintaining homeostasis. Therefore, it is important to adjust the individual’s nutritional supply and physical activities. Numerous studies suggest evaluation of energy expenditure in various Caucasian and few studies in Asian population. However there is dearth of literature relating to evaluation of components of e...

OBJECTIVES To systematically review levels of metabolic expenditure and changes in activity patterns associated with active video game (AVG) play in children and to provide directions for future research efforts. DATA SOURCES A review of the English-language literature (January 1, 1998, to January 1, 2010) via ISI Web of Knowledge, PubMed, and Scholars Portal using the following keywords: vid...
