SIT LESS 3: The Effect of Low Intensity Physical Activity on Insulin Sensitivity, Mood and Cognitive Performance
A study testing Physical activity regime in people with Overweight and Obesity, run by Maastricht University Medical Center at 1 site in Netherlands.
Trial summary
Background of the study: A sedentary lifestyle and obesity are well known risk factors of type 2 diabetes. The major focus of current guidelines for type 2 diabetes prevention is on energy balance. Physical activity guidelines recommend at least 30 minutes/day of moderate to vigorous physical activity (MVPA). Read more about this study

About this study
Background of the study:
A sedentary lifestyle and obesity are well known risk factors of type 2 diabetes. The major focus of current guidelines for type 2 diabetes prevention is on energy balance. Physical activity guidelines recommend at least 30 minutes/day of moderate to vigorous physical activity (MVPA). However, no advice is given how the other 23.5 hours of the day should be spent. Several recent epidemiologic studies suggest that excessive sitting, independent of moderate to vigorous physical activity, has detrimental health effects. Another possibility to sit less is by increasing low intensity physical activities as slowly walking and standing. A recent published study of Duvivier and colleagues suggests that sitting less and replacing it by slowly walking and standing has a better effect on insulin action and cardiovascular risk factors than the combination of one hour MVPA per day and sitting the rest of the day in healthy subjects (Duvivier et al. PLOS ONE 2013). Until now this research is not performed in subjects with overweight/obesity.

Information already included in arm descriptions
| Study group | Role | What they receive |
|---|---|---|
| Sitting regime | Experimental | The subjects will follow the sitting regime during four days. Each day: 14 hours sitting, 1 hour walking and 1 hour standing and 8 hours sleeping. Receives: Behavioral: Physical activity regime |
| Sit Less regime | Experimental | Subjects will follow the sit less regime during four days. Each day will consist of 9 hours sitting, 4 hours walking, 3 hours standing and 8 hours sleeping. The walking and standing will be done in a minimum of eight bouts with a time interval of >1 hour. The subjects will be instructed to walk on a slow pace, i.e. 2-3 km/h, which is comparable to walking during shopping, walking to the office etc. Receives: Behavioral: Physical activity regime |

Questions about this trial
What is this clinical trial studying?
A study testing Physical activity regime in people with Overweight and Obesity, run by Maastricht University Medical Center at 1 site in Netherlands.
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 7 inclusion and 15 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 16 Mar 2016. 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 Netherlands. 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 insulin levels (measured as area under the curve during an oral glucose tolerance test) (time frame: one day after each regime). 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 NCT02394249, 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?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Mar 2016; AzTrials last refreshed its copy on 6 Nov 2026.
