Expectancy beliefs and task values are two essential motivators in physical education. This study was designed to identify the relation between the expectancy-value constructs (Eccles & Wigfield, 1995) and high school students’ physical activity behavior as associated with their energy balance knowledge. High school students (N = 195) in two healthful-living programs (i.e., combination of physi...

OBJECTIVE Estrogen plays an important role in feeding and energy balance, and the critical role of estrogen in the control of appetite and energy balance is mediated by hypothalamic estrogen receptor (ER) alpha. In undernourished rodents, hypothalamic ER alpha mRNA expression are decreased. Responses of some hypothalamic factors to negative energy balance develop during the early neonatal perio...

Many athletes in aesthetic and weight dependent sports are at risk of energy imbalance. However little is known about the exercise and eating behaviours of highly trained dance populations. This investigation sought to determine the energy intake and energy expenditure of pre-professional female contemporary dancers. Twenty-five female contemporary dance students completed the study. Over a 7-d...

The amount of body fat and the energy balance are important factors that influence the timing of puberty and the normal reproductive function. Leptin is a key hormone that conveys to the central nervous system information about the individual energy reserve and modulates the hypothalamus-pituitary-gonad (HPG) axis. Recent findings suggest that the ventral premammillary nucleus (PMV) mediates th...

Hypothalamic neuropeptides play essential roles in regulating energy and body weight balance. Energy imbalance and obesity have been linked to hypothalamic signaling defects in regulating neuropeptide genes; however, it is unknown whether dysregulation of neuropeptide exocytosis could be critically involved. This study discovered that synaptotagmin-4, an atypical modulator of synaptic exocytosi...

The aim of this study was to analyse whether automatic milking has an effect on reproduction in dairy cows. Probably the most important consequence of automatic milking is an increased milking frequency. More frequent milking means more production and thereby an extra threat for the energy balance during the first months of lactation. A deep negative energy balance (NEB) is often followed by ne...

Using indicator-based assessment, this study examines the energy security of nine Association of Southeast Asian Nations (ASEAN) member countries to see how it has evolved over the past 12 years and identifies a country-specific energy security context for each country. The assessment uses 42 energy security indicators, which can be separated into five components: overall energy balance, socio-...

Abstract Most dairy cows experience negative energy balance (NEB) in early lactation because demand for milk synthesis is not met by intake. Excessive NEB may lead to metabolic disorders and impaired fertility. To optimize herd management, it useful detect lactation, but direct calculation of feasible commercial herds. Alternative methods rely on fat-to-protein ratio or concentrations non-ester...

It is a commonly held belief that exercise (one method of inducing an energy deficit) causes a compensation in energy intake to match the exercise-induced energy expenditure. This could possibly lead to the belief that exercise is not a useful method of weight loss which could then be used as an excuse not to exercise. However, there is no compelling evidence to suggest that exercise drives hun...
