About this study

Official title: A Pilot Trial to Assess the Effect of a Protein-Nutrition Beverage on Skeletal Muscle Protein Synthesis in Women

This study investigates whether a protein-nutrition beverage can increase muscle protein synthesis to a similar magnitude as a control beverage.

Read the detailed description

Potential participants will be screened, and if eligible, invited to participate. Body composition and physical activity level will be assessed during the initiation visit. During the trial visits, women receive a protein-nutrition beverage; muscle protein synthesis is assessed via blood analytes and muscle biopsies at rest and after exercise. Statistical analysis includes mixed model regression approach with change in muscle protein synthesis as the primary outcome.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Protein-nutrition beverageOther

    Intervention involves consumption of one protein-nutrition beverage after exercise bout and 2 times per day for 5 days thereafter

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change (timei -baseline) of muscle protein synthesis at rest and following exercise in response to the protein-nutrition beverages compared to a control beverage

    Measured: 0-3 hours post consumption and 5 days post consumptions

Secondary outcomes (1)
  1. Change (timei -baseline) of blood sample analytes at rest and following exercise in response to the protein-nutrition beverages compared to a control beverage

    Measured: 0-3 hours post consumption and 5 days post consumptions

Questions about this trial

What is this clinical trial studying?

A study testing Protein-nutrition beverage in people with Muscle Protein Synthesis, run by PepsiCo Global R&D at 1 site in Canada.

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 8 inclusion and 10 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 10 Mar 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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?

Change (timei -baseline) of muscle protein synthesis at rest and following exercise in response to the protein-nutrition beverages compared to a control beverage (time frame: 0-3 hours post consumption and 5 days post consumptions). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02282566, which also lists 2 linked publications.

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 10 Mar 2021.
