Protein Requirements In Active Populations
A study testing Amino Acid Intake in people with Increased Metabolic Requirement and Healthy, run by University of Toronto.
Trial summary
Protein requirements in active individuals have been suggested to be greater than the current recommended dietary allowance (RDA). Nutritional requirements for dietary amino acids in adults have traditionally been determined utilizing the nitrogen balance technique, which is prone to underestimating protein… Read more about this study

About this study
Official title: Evaluation of Protein Requirements in Active, Young Adult Males
Protein requirements in active individuals have been suggested to be greater than the current recommended dietary allowance (RDA).
Nutritional requirements for dietary amino acids in adults have traditionally been determined utilizing the nitrogen balance technique, which is prone to underestimating protein requirements. As a result, there is a need to re-evaluate recommendations in order to characterize how dietary amino acid needs may be modulated by physical activity.
Read more
Recent studies using the minimally invasive indicator amino acid oxidation (IAAO) technique have suggested that protein requirements in young men are at least 50% higher than the RDA based on nitrogen balance data.
The purpose of this study is to measure the protein requirement in active, young adult males using the IAAO technique in the presence of a variable intensity exercise stimulus.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Amino Acid IntakeDietary supplement
Amino acid intakes will be varied at 0.2-2.6 g/kg/day
| Study group | Role | What they receive |
|---|---|---|
| Active, Young Adult Males | Experimental | Subjects will receive different levels of amino acid intakes varying from 0.2 to 2.6 g/kg/day. Receives: Dietary Supplement: Amino Acid Intake |

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

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?
13CO2 (carbon dioxide) excretion (μmol/kg/h) (time frame: 4 hours / study day). 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 NCT02478814, which also lists 1 linked publication.
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?
