About this study

Official title: Identification of Novel Skeletal Muscle-derived Factors That Promote Lipid Oxidation in Both Skeletal Muscle and Adipose Tissue

The purpose of this study is to collect data to help researchers identify factors, such as certain proteins or genetic codes, that are secreted from muscle that are associated with the beneficial effects of exercise.

Read the detailed description

Study Objectives:

  1. To identify specific changes in messenger ribonucleic acid (mRNA)/micro ribonucleic acid (miRNA) expression in muscle associated with higher or lower relative measures of mitochondrial capacity and fat oxidation.
  2. To identify secreted factors/miRNAs that specifically relate to the metabolic response of muscle and that are present after a single initial bout of exercise.
  3. To collect the appropriate clinical samples (muscle and adipose tissue, plasma/serum) to enable validation of myokines associated with changes in oxygen consumption/mitochondrial content via in vivo and in vitro discovery efforts.

What participants receive

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

  • ExerciseBehavioural

    A 5-minute warm-up and a 5-minute cool-down prior to and following each exercise session, respectively. There will be alternating days of interval training and aerobic training. The interval training will be performed on an upright stationary bike, while the aerobic training will be performed on a treadmill. The interval training will consist of five-minute bouts of higher intensity alternated with 4 minutes of lower intensity for a total duration of 45 minutes. Intensity will increase each week. The aerobic training component will be fixed at a moderate intensity, but will increase in duration each week from 45 minutes to 75 minutes to 90 minutes during the third and final week.

What is being measured

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

  1. Measure change in mitochondrial capacity

    The difference will be measured in obese, lean and athletic participants.

    The Phosphocreatine (PCr) recovery time constant and the PCr level in oxygenated muscle at rest will be used to calculate maximum mitochondrial capacity.

    Measured: Baseline (Day -6), Day 18

Secondary outcomes (2)
  1. Measure change of expression of proteins

    The difference will be measured in obese, lean and athletic participants.

    This will be taken from muscle biopsy and/or blood plasma samples obtained at baseline, before and after exercise.

    Measured: Baseline (Day -6), Day 0, Day 5, Day 12, Day 18

  2. Measure change in mRNA/miRNA levels

    The difference will be measured in obese, lean and athletic participants.

    This will be taken from muscle biopsy and/or blood plasma samples obtained at baseline, before and after exercise.

    Measured: Baseline (Day -6), Day 0, Day 5, Day 12, Day 18

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 15 inclusion and 38 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: under way, not looking for participants, as of the sponsor's last update on 30 Mar 2026. 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. 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?

This study is still under way. Results are not available in the source record yet.

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?

Measure change in mitochondrial capacity (time frame: Baseline (Day -6), Day 18). 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 NCT01911091, which also lists 82 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 30 Mar 2026.
