A study testing Prolonged Standing and Prolonged Sitting in people with Metabolic Syndrome and Atherosclerosis, run by University of Texas at Austin at 1 site in United States.
Trial summary
The effects of 12 hours of prolonged standing will be compared to prolonged standing on a high fat tolerance test the following day. Plasma triglycerides, insulin, and glucose will be measured in a crossover study design. Read more about this study

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Prolonged StandingBehavioural
Subject will stand for 12 hours and undergo a high fat tolerance test the subsequent day
Prolonged SittingBehavioural
Subject will sit for 12 hours and undergo a high fat tolerance test the subsequent day
| Study group | Role | What they receive |
|---|---|---|
| Prolonged Standing | Experimental | Subject stand for 12 hours. The following day the subject will undergo a high fat tolerance test. Order of sitting/standing will be random and each subject will perform both interventions. Receives: Behavioral: Prolonged Standing |
| Prolonged Sitting | Experimental | Subject sit for 12 hours. The following day the subject will undergo a high fat tolerance test. Order of sitting/standing will be random and each subject will perform both interventions. Receives: Behavioral: Prolonged Sitting |
What is being measured

Questions about this trial
What is this clinical trial studying?
A study testing Prolonged Standing and Prolonged Sitting in people with Metabolic Syndrome and Atherosclerosis, 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 7 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 4 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). The study lists 3 primary outcomes in all. 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 4 Oct 2018; AzTrials last refreshed its copy on 6 Nov 2026.
