Inactivity Duration on Lipid Metabolism
United States8 participantsStarted 2023-10-01
Plain-language summary
The purpose of the study is to investigate the effect of different periods of physical inactivity on postprandial lipid metabolism in the morning after exercise by measuring plasma triglyceride levels and fat oxidation (burning). The study is a crossover intervention with all healthy participants performing three trials varying in length of physical inactive (12 hours, 24 hours, and 36 hours). All trials include a physical activity control phase (\>10,000 steps/24hr), a physical inactive phase (\<1,000 - 1,500 steps/12hr), a moderate intensity cycling session, and a high-fat tolerance test.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Fat oxidation (fat burning)
Timeframe: A total of 5 measurements will be done, specifically are before the high fat meal (baseline) and each hour after the high fat meal for 4 hours. The whole test takes about 5 hours from 9 am to 2 pm on the last day of each trial.
2
Plasma triglyceride
Timeframe: A total of 5 measurements will be done, specifically are before the high fat meal (baseline) and each hour after the high fat meal for 4 hours. The whole test takes about 5 hours from 9 am to 2 pm on the last day of each trial.
