This paper presents an activity recording (AR) system and a radial-basis-function-network-based (RBFNB) energy expenditure regression algorithm. The AR system includes motion sensors and an electrocardiogram sensor which is composed of a set of sensor modules (accelerometers and electrocardiogram amplifying/filtering circuits), a MCU module (microcontroller), a wireless communication module (a ...

We examined the hypothesis that weight loss in heart failure patients is associated with elevated daily energy expenditure. Twelve cachectic patients [age = 73 +/- 6 yr; weight loss = 15 +/- 6 kg; body mass index (BMI) = 21 +/- 5 kg/m2], 13 noncachectic patients (age = 67 +/- 5 yr; BMI = 27 +/- 5 kg/m2), and 50 healthy elderly controls (age = 69 +/- 6 yr; BMI = 26 +/- 4 kg/m2) were studied. Dai...

Exercise is a common component of weight loss strategies, yet exercise programs are associated with surprisingly small changes in body weight [1-4]. This may be due in part to compensatory adaptations, in which calories expended during exercise are counteracted by decreases in other aspects of energy expenditure [1, 5-10]. Here we examined the relationship between a rodent model of voluntary ex...

Physical activity (PA) is an important non-therapeutic tool in primary prevention and treatment of diabetes mellitus (DM). To improve activity-based health management, patients need to quantify activity-related energy expenditure and the other components of total daily energy expenditure. This review explores differences between the components of total energy expenditure in patients with DM and...

BACKGROUND Childhood stunting has been associated with an increased risk of obesity in adulthood, but the causes are unclear. This study hypothesizes that stunting significantly reduces both resting and activity energy expenditure. AIM To assess and describe energy expenditure of low socio-economic Maya children and to determine whether stunting is independently related to energy expenditure ...

1. Our objectives were to measure total energy expenditure, the daily variation in total energy expenditure and the physical activity level in a group of HIV-positive subjects using the bicarbonate-urea method. The study also aimed to asses the practicalities of using the bicarbonate-urea technique in free-living conditions. 2. Total energy expenditure was measured with the bicarbonate-urea met...

Understanding the genetic factors of obesity requires consideration of the genetic basis of the underlying etiological factors including energy expenditure and substrate utilization. Genetic susceptibility studies suggest that altered energy expenditure and/or preferential substrate utilization are likely to be involved in the etiology of obesity. Twin and family studies suggest that there is a...

Both overnutrition and undernutrition affect energy metabolism, with overnutrition raising energy expenditure and undernutrition lowering it. Fever is a powerful stimulator of thermogenesis. In diseases such as cancer, AIDS, diabetes mellitus, and rheumatoid arthritis, whether energy expenditure is increased or decreased often depends on how advanced the disorder is. Early on, when the greater ...

BACKGROUND Physical activity has good influence on health. The physical activity of elderly people may decrease, because of the health problems or think that with aging sport activity should be reduced. OBJECTIVE The aim of the study was to assess a physical activity and energy expenditure of people in age 60 and more in the Koprzywnica district (Poland). MATERIAL AND METHODS 95 persons in ...

the aim of the present study was to examine the effect of menstrual cycle on substrate metabolism, energy expenditure and performance during exhaustive incremental exercise in female students. for this purpose, 15 female students (mean age 21.17 ± 1.47 years, bmi 20.55 ± 1.71 kg/m2) participated voluntarily in this study. the design was adjusted in three stages: bleeding, follicular and the lat...
