OBJECTIVE Preclinical studies indicate that oxytocin is anorexigenic and has beneficial metabolic effects. Oxytocin effects on nutrition and metabolism in humans are not well defined. It was hypothesized that oxytocin would reduce caloric intake and appetite and alter levels of appetite-regulating hormones. Metabolic effects of oxytocin were also explored. METHODS A randomized, placebo-contro...

Definitive risk factors for endometriosis remain unknown due to the lack of knowledge concerning the pathogenesis of the condition, and little research has evaluated endometriosis within the adolescent population. The purpose of this cross-sectional descriptive study was to compare the exercise habits, cigarette smoking, alcohol consumption, and caffeine intake between adolescent girls with and...

The purpose of the present case study was threefold: (a) to estimate intake and expenditure of a dog driver (musher) while participating in the Iditarod, (b) to determine the hydration status of the musher at the completion of the event, and (c) to evaluate training related changes in aerobic capacity and body composition of a long-distance dog sled driver in preparation for and following compl...

Astaxanthin, a xanthophyll carotenoid, accelerates lipid utilization during aerobic exercise, although the underlying mechanism is unclear. The present study investigated the effect of astaxanthin intake on lipid metabolism associated with peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α) in mice. Mice were divided into 4 groups: sedentary, sedentary and astaxanthin-treated, ...

BACKGROUND Aerobic glycolysis, a hallmark of cancer, is characterized by increased metabolism of glucose and production of lactate in normaxia. Recently, pyruvate kinase M2 (PKM2) has been identified as a key player for regulating aerobic glycolysis and promoting tumor cell proliferation and survival. METHODS Tandem affinity purification followed up by mass spectrometry (TAP-MS) and co-immuno...

BACKGROUND While compensatory eating following acute aerobic exercise is highly variable, little is known about the underlying mechanisms that contribute to the alterations in exercise-induced eating behaviour. METHODS Overweight and obese women (body mass index=29.6±4.0 kg/m(2)) performed a bout of cycling individually tailored to expend 400 kcal (EX) or a time-matched no exercise control co...

BACKGROUND Adequate nutrition and energy intake play key rule during the training period and recovery time. The assessment of athlete's energetic needs should be calculated individually, based on personal energy expenditure and Sense Wear PRO3 Armband (SWA) mobile monitor is a useful tool to achieve this goal. However, there is still few studies conducted with use of this monitor. OBJECTIVES ...
