About this study

The purpose of this study is to investigate the effect of 4 days of sitting and moderate exercise on plasma triglyceride elevation after a meal.

Read the detailed description

Subjects will undergo three weeks (two intervention, one washout) of testing during which they will participate in two conditions: 1) prolonged sitting (~14-hours/day) with a 1-hour bout of acute exercise at 65% of pre-intervention VO2max and 2) prolonged sitting (~14-hours/day) without an acute bout of exercise. During each intervention week, subjects will have 2 days of dietary and activity control, followed by 4 days during which prolonged sitting will occur. On the evening of the 4th day, subjects in the exercise group will perform the acute bout of exercise. On day 5, all subjects will undergo a lipid tolerance test to determine the body's ability to clear triglycerides from the blood as well as insulin/glucose response and substrate oxidation. Blood samples will be assayed for the previously mentioned substances and postprandial gas collection will be analyzed via indirect calorimetry.

What participants receive

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

  • Prolonged sitting with exerciseBehavioural

    Subjects will have a 2-day control period during which step count and diet will be controlled for and recreated for the other trial. Following this 2-day period, they will undergo the prolonged sitting trial with the acute bout of exercise on day 4. Day 5 will consist of the lipid tolerance test to determine the ability of the body to clear triglycerides.

  • Prolonged sitting without exerciseBehavioural

    Subjects will have a 2-day control period during which step count and diet will be controlled for and recreated for the other trial. Following this 2-day period, they will undergo the prolonged sitting trial, but will not be asked to complete an acute bout of exercise on day 4. Day 5 will consist of the lipid tolerance test to determine the ability of the body to clear triglycerides.

Prolonged sitting with exerciseExperimentalSubjects will be asked to undergo prolonged sitting (~14-hours/day) for 4 days. On the evening of day 4, they will be asked to run at 65% of VO2max for 1-hour.
Receives: Behavioral: Prolonged sitting with exercise
Prolonged sitting without exerciseExperimentalSubjects will be asked to undergo prolonged sitting (~14-hours/day) for 4 days. Subjects will not be asked to complete the acute bout of exercise to serve as a control.

What is being measured

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

  1. Plasma Triglycerides

    Areas under the curve for triglyceride concentration will be calculated for hourly samples from a 6-hour lipid tolerance test

    Measured: 6-hours

Secondary outcomes (2)
  1. Plasma Insulin

    Areas under the curve for insulin concentration will be calculated for hourly samples from a 6-hour lipid tolerance test

    Measured: 6-hours

  2. Plasma Glucose

    Areas under the curve for glucose concentration will be calculated for hourly samples from a 6-hour lipid tolerance test

    Measured: 6-hours

Questions about this trial

What is this clinical trial studying?

A study testing Prolonged sitting with exercise and Prolonged sitting without exercise in people with Atherosclerosis and Metabolic Syndrome, run by University of Texas at Austin 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 5 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 5 Oct 2018. 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?

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?

Plasma Triglycerides (time frame: 6-hours). 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 5 Oct 2018.
