PURPOSE This study aimed to evaluate the energy expenditure and energy intake as an experiment of energy balance of elite Taekwondo players receiving summer vs. winter intensive training. METHODS The summer training group (STG, n = 15) and the winter training group (WTG, n = 18) wore an accelerometer for the measurement of energy expenditure and maintained a daily dietary record for measureme...

There is a sparsity of data on energy expenditure in young children. We therefore examined the components of daily energy expenditure in a group of 30 children (16 boys, 14 girls; age 4-6 yr) characterized for body weight, height, heart rate, and body composition from bioelectrical resistance. Total energy expenditure (TEE) was measured over 14 days under free living conditions by doubly labele...

Compared to traditional weight loss strategies, the compensatory decrease in energy expenditure in response to body weight loss is markedly attenuated after Roux-en-Y gastric bypass surgery (RYGB). Because basal and postprandial levels of glucagon-like peptide-1 (GLP-1) are increased after RYGB surgery, and because GLP-1 has been shown to increase energy expenditure, we investigated if increase...

BACKGROUND Guatemala has experienced a substantial increase in overweight and obesity in recent years, yet physical activity patterns and consequent energy expenditure are largely unexplored in this population. METHODS To describe overall physical activity levels (PAL) and activities contributing to daily energy expenditure, we analyzed time spent in daily activities as reported by 985 women ...

Energy balance and body composition were studied in 10 cancer patients to investigate the interrelationship between energy expenditure and energy intake in the development of cancer cachexia. These data were com pared to the findings in control patients of similar age with diseases affecting physical activities to about the same extent. The measurements of energy expenditure and intake were rep...

BACKGROUND Physical activity in the elderly is influenced by aspects of aging that cause personal, mental, environmental, and social changes. Increases in factors that are barriers to activity cause physical energy expenditure to decrease. OBJECTIVES The aim of the present study was to survey the relationship between energy expenditure in metabolic equivalent units (MET) and factors that are ...

BACKGROUND Low levels of energy expenditure and aerobic fitness have been hypothesized to be risk factors for obesity. Longitudinal studies to determine whether energy expenditure influences weight gain in whites have provided conflicting results. To date, no studies have examined this relationship in blacks or whether aerobic fitness influences weight gain in white or black children. METHODS...

Obesity can impact on reproductive functions by causing hormonal imbalance and ovulatory dysfunction. Furthermore, obesity is associated with a range of adverse health consequences. There is a tight coupling between the reproductive system and energy balance. Obesity results from chronic imbalance between energy intake and energy expenditure, and therefore changes in energy expenditure impact o...

To compare energy expenditure during and after active and handheld video game drumming compared to walking and sitting. Ten experienced, college-aged men performed four protocols (one per week): no-exercise seated control (CTRL), virtual drumming on a handheld gaming device (HANDHELD), active drumming on drum pads (DRUM), and walking on a treadmill at ~30% of VO2max (WALK). Protocols were perfo...

Changes in energy regulation occur during normal aging and contribute to the common phenomenon of weight and fat losses late in life. This review synthesizes data on aging-related changes in energy intake and energy expenditure and on the regulation of energy intake and expenditure. The ability of older adults to accurately regulate energy intake is impaired, with a number of possible explanati...
