Resistance Exercise, Recovery Drinks and Appetite
A study testing Protein drink and Carbohydrate drink in people with Active Population, run by Loughborough University.
Trial 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. Read more about this study

About this study
Official title: 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.
Read the 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.

| Study group | Role | What they receive |
|---|---|---|
| Protein | Experimental | 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. Receives: Dietary Supplement: Protein drink |
| Carbohydrate | Experimental | 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. Receives: Dietary Supplement: Carbohydrate drink |

Questions about this trial
What is this clinical trial studying?
A study testing Protein drink and Carbohydrate drink in people with Active Population, run by Loughborough University.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 9 May 2016. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Ad-libitum energy intake (time frame: 65 min post-exercise). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 May 2016.
