  • daily
  • This mini-review provides an overview of the applicability of the SenseWear armband (SWA), which combines accelerometry with measurements of heat production and skin conductivity, to measure total daily energy expenditure (TDEE) and its components such as exercise energy expenditure (ExEE) in athletic populations. (frontiersin.org)
  • One of the unique characteristics of athletes is that energy requirements of training and competition increase their total daily energy expenditure (TDEE) beyond those of the general population ( Westerterp, 2013 ). (frontiersin.org)
  • high
  • Because of the high energy demands and the consequences of energy deficiency, tracking EE is paramount for many athletes and their support staff. (frontiersin.org)
  • exercise
  • Considering that athletes expend up to 75% of their TDEE during exercise ( Westerterp, 2013 ), quantifying energy needs during training and competition requires particular attention. (frontiersin.org)
  • food
  • It is hypothesized that Depakote treatment will result in increased food intake. (clinicaltrials.gov)
  • Potential targets include interventions to modify food intake and physical activity. (clinicaltrials.gov)
  • The degree to which each behavior (food intake or physical activity) will be targeted is dependent on the results of this study. (clinicaltrials.gov)
  • For instance, if the majority of the weight gain associated with Depakote treatment is due to changes in food intake, stronger dietary interventions will be suggested. (clinicaltrials.gov)
  • Additionally, changes in endocrine factors (hormones and peptides) will be evaluated during the study to determine if Depakote is associated with an altered endocrine response that affects satiety, food intake, or energy expenditure. (clinicaltrials.gov)
  • Phase IV Study of the Effects of Divalproex Sodium on Food Intake and Energy Expenditure. (clinicaltrials.gov)
  • Change in Food Intake. (clinicaltrials.gov)
  • Change in food intake from baseline to week 3. (clinicaltrials.gov)
  • Energy intake and expenditure in women runners and non-runners were assessed by weighed food records, evaluation of minute-by-minute activity diaries, and indirect calorimetry. (cambridge.org)
  • yet when food is easily accessible, intake surpasses that needed. (pnas.org)
  • Proposed mechanisms that associate insufficient sleep and higher body mass index (BMI) include changes in satiety and hunger hormones altering food intake and changes in EE ( 17 ). (pnas.org)
  • In a sub-sample of the 1993 Pelotas (Brazil) birth cohort, followed up in 2006-7, information on intake was obtained through a food-frequency questionnaire (FFQ) and three 24-hour-recalls (24hR), while energy expenditure was assessed using an accelerometer. (ufrgs.br)
  • This study examined the effects of an acute bout of exercise of low-intensity on food intake and energy expenditure over four days in women taking oral contraceptives. (shu.ac.uk)
  • In addition to these behavioural factors, multistructural variables such as the physical environment and socioeconomic status have been shown to have a significant influence on food intake and energy expenditure [ 10 , 18 ]. (hindawi.com)
  • however, human food intake must also be evaluated within the context of non-physiological determinants present in human life. (wikipedia.org)
  • Body weight regulation requires a balance between food intake and energy expenditure. (wikipedia.org)
  • Two mechanisms are required to maintain a relatively constant body weight: one must increase motivation to eat if long-term reservoirs are being depleted, and the other must restrain food intake if more calories than needed are being consumed. (wikipedia.org)
  • As food scarcity and availability have become less and less of a problem, food intake has increased. (wikipedia.org)
  • The increase of food intake by so many people is due primarily to a number of environmental factors. (wikipedia.org)
  • There are two primary sources of signals that stop eating: short-term signals come from immediate effects of eating a meal, beginning before food digestion, and long-term signals, that arise in adipose tissue, control the intake of calories by monitoring the sensitivity of brain mechanisms to hunger and satiety signals received. (wikipedia.org)
  • This effect is exacerbated if the human host is already ingesting far less food than is required to meet their daily caloric intake needs. (wikipedia.org)
  • Mice deficient for this gene have increased fat mass despite decreased food intake suggesting a role for this gene product in the regulation of energy homeostasis. (wikipedia.org)
  • Consistent with Coleman's and Leibel's hypothesis, several subsequent studies from Leibel's and Friedman's labs and other groups confirmed that the ob gene encoded a novel hormone that circulated in blood and that could suppress food intake and body weight in ob and wild type mice, but not in db mice. (wikipedia.org)
  • The orexin system was initially suggested to be primarily involved in the stimulation of food intake, based on the finding that central administration of orexin-A and -B increased food intake. (wikipedia.org)
  • The FTO gene expression was also found to be significantly upregulated in the hypothalamus of rats after food deprivation and strongly negatively correlated with the expression of orexigenic galanin-like peptide which is involved in the stimulation of food intake. (wikipedia.org)
  • In the late 1960s, non-selective serotonin receptor antagonists demonstrated a relationship between serotonin receptors and food intake. (wikipedia.org)
  • As a result of these symptoms, the researchers identified a functional role for the receptors in serotonergic regulation of food intake and body weight. (wikipedia.org)
  • Fenfluramine's anorectic effect is achieved through an increase in serotonin levels, imparting a sensation of fullness, which leads to a lower intake of food. (wikipedia.org)
  • Repeated administration of mCPP to humans might result in decreased food intake and weight loss. (wikipedia.org)
  • Some physiological substrates that underlie food intake and alcohol intake have been identified. (wikipedia.org)
  • Melanocortins, a group of signaling proteins, are found to be involved in both excessive food intake and alcohol intake. (wikipedia.org)
  • The effect that eating has on weight gain can vary greatly depending on the following factors: energy (calorie) density of foods, exercise regimen, amount of water intake, amount of salt contained in the food, time of day eaten, age of individual, individual's country of origin, individual's overall stress level, and amount of water retention in ankles/feet. (wikipedia.org)
  • The idea is revolutionary because it shifts the fundamental locus of control over energy expenditure from extrinsic factors outside the animal (e.g. food supply, fractal supply system, uptake capacity), to intrinsic factors inside an animal (heat dissipation capacity). (wikipedia.org)
  • Since this discovery, many other hormonal mechanisms have been elucidated that participate in the regulation of appetite and food intake, storage patterns of adipose tissue, and development of insulin resistance. (wikipedia.org)
  • In particular, they and other appetite-related hormones act on the hypothalamus, a region of the brain central to the regulation of food intake and energy expenditure. (wikipedia.org)
  • The vagus nerve provides efferent nervous signals out from the hunger and satiety centers of the hypothalamus, a region of the brain central to the regulation of food intake and energy expenditure. (wikipedia.org)
  • Animals with lesioned VMH will gain weight even in the face of severe restrictions imposed on their food intake, because they no longer provide the signaling needed to turn off energy storage and facilitate energy burning. (wikipedia.org)
  • obese
  • Combining caffeine with exercise creates a greater acute energy deficit, and the implications of this protocol for weight loss or maintenance over longer periods of time in overweight/obese populations should be further investigated. (edu.au)
  • In 1949, a non-obese mouse colony being studied at the Jackson Laboratory produced a strain of obese offspring, suggesting that a mutation had occurred in a hormone regulating hunger and energy expenditure. (wikipedia.org)
  • Other factors beside energy balance that may contribute to gaining weight include: A study, involving more than 12,000 people tracked over 32 years, found that social networks play a surprisingly powerful role in determining an individual's chances of gaining weight, transmitting an increased risk of becoming obese from wives to husbands, from brothers to brothers and from friends to friends. (wikipedia.org)
  • insulin
  • The vagus nerve is thought to be one key mediator of these effects, as lesions lead to chronic elevations in insulin secretion, promoting energy storage in adipocytes. (wikipedia.org)
  • libitum
  • Two hours after exercise, participants were offered an ad libitum test meal where energy and macronutrient intake were recorded. (edu.au)
  • carbohydrates
  • We also found that transitioning from an insufficient to adequate/recovery sleep schedule decreased energy intake, especially of fats and carbohydrates, and led to −0.03 ± 0.50 kg weight loss. (pnas.org)
  • suggests
  • Findings are inconclusive because alcohol itself contains 7 calories per gram, but research suggests that alcohol energy is not efficiently used. (wikipedia.org)
  • differences
  • In spite of the great differences between energy intake obtained using the two methods, lower differences were observed when these methods were compared to expenditure. (ufrgs.br)
  • The large differences among endothermic (warm-blooded) mammalian and ectothermic (cold-blooded) teleost leptins raised the question of whether the energy homeostatic functions of the teleost leptins are conserved. (wikipedia.org)
