About this study

Official title: A Randomized, Controlled Double Blind Longitudinal Study: Effect of Protein Blend Supplementation During Exercise Training on Muscle Growth and Strength

This study will investigate the effects of a soy/dairy protein blend on muscle growth and strength. In sports nutrition and in aging it is important to have healthy muscles. This can be achieved with exercise and nutrition. Consumption of protein following resistance exercise can promote healthy muscle growth and help improve strength. Young healthy men will be studied during a 12 week resistance exercise training program and be given protein supplements every day during the study. The hypothesis is that a blend of soy, whey and casein will induce a greater muscle gain and strength increase than the control.

Questions about this trial

What is this clinical trial studying?

A study testing Blend and Whey in people with Muscle, run by DuPont Nutrition and Health at 1 site in United States.

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 1 inclusion and 19 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 7 Oct 2019. 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 United States. 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 in Muscle Mass (time frame: Baseline, 6 weeks, 12 weeks). 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 NCT01749189, which also lists 3 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 7 Oct 2019.
