The effects of prolonged treadmill running on appetite, energy intake and acylated ghrelin (an appetite stimulating hormone) were examined in 9 healthy males over the course of 24h. Participants completed 2 experimental trials (exercise and control) in a randomised-crossover fashion. In the exercise trial participants ran for 90 min at 68.8 + or - 0.8% of(More)
Since its discovery in 1999, ghrelin has been implicated in a multiplicity of physiological activities. Most notably, ghrelin has an important influence on energy metabolism and after the identification of its potent appetite stimulating effects ghrelin has been termed the 'hunger hormone'. Exercise is a stimulus which has a significant impact on energy(More)
Swimming may stimulate appetite and food intake but empirical data are lacking. This study examined appetite, food intake, and plasma acylated ghrelin responses to swimming. Fourteen healthy males completed a swimming trial and a control trial in a random order. Sixty min after breakfast participants swam for 60 min and then rested for six hours.(More)
This study investigated the acute influence of exercise on eating behaviour in an ecologically valid setting whereby healthy active males were permitted complete ad libitum access to food. Ten healthy males completed two, 8h trials (exercise and control) in a randomised-crossover design. In the exercise trials participants consumed a breakfast snack and(More)
PURPOSE To explore whether compensatory responses to acute energy deficits induced by exercise or diet differ by sex. METHODS In experiment one, 12 healthy women completed three 9-h trials (control, exercise-induced (Ex-Def) and food restriction-induced energy deficit (Food-Def)) with identical energy deficits being imposed in the Ex-Def (90-min run, ∼70%(More)
There is considerable interest in whether non-nutritive sweeteners are sensed in the gastrointestinal tract to modulate appetitive or absorptive responses to ingested carbohydrate. We determined the effect of a panel of non-nutritive sweeteners, aspartame, saccharin and acesulfame-K, delivered in doses that would be consumed in normal usage. Each was given(More)
