Resistance Exercise, Recovery Drinks and Appetite

Effect of Recovery Drink Composition Consumed After Resistance Exercise on Subsequent Appetite and Energy Intake

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.

Study Overview

• Status: Completed
• Conditions: Active Population
• Intervention / Treatment: Dietary supplement: Protein drink; Dietary supplement: Carbohydrate drink

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 and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: 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.	Dietary supplement: Protein drink; The protein drink was administered during this trial
Experimental: 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.	Dietary supplement: Carbohydrate drink; The carbohydrate drink was administered in this trial
