Study Overview
Brief Summary
Whilst the effects of manipulating the macronutrient content of foods on appetite and energy intake has been relatively well studied at rest, little is known about these responses in a post-exercise context. The effect of post-exercise nutrition on recovery from or adaptation to exercise has been well studied. However, many exercisers do so for weight management and thus any post-exercise nutrition might impact on energy balance and might need to be carefully considered. This study will examine the impact of manipulating the composition of a recovery drink consumed after resistance exercise on subsequent appetite and energy intake.
Detailed Description
Subjects perform a bout of lower body resistance exercise lasting ~50 min and immediately post-exercise they consume one of two recovery drinks over a 5 min period. Over the next 60 min subjective appetite responses will be measured and then 60 min after drink ingestion, subjects will consume an ad-libitum meal.

Arms & Interventions
Protein
In this arm the subjects were provided with a PROTEIN drink to consume after exercise. This protein drink contained whey protein isolate that provided 0.3 g/ kg body mass of protein.
Intervention: Protein drink (Dietary Supplement)
Carbohydrate
In this arm the subjects were provided with a CARBOHYDRATE drink to consume after exercise. This carbohydrate drink was energy matched to the protein drink in the other arm of the experiment.
Intervention: Carbohydrate drink (Dietary Supplement)
