Trial summary

Physical inactivity is a significant predictor of major non-communicable diseases such as type 2 diabetes (7%), cardiovascular disease (6%), musculoskeletal disorders and some cancers, and has been proposed to be the 4th leading cause of death worldwide. Read more about this study

About this study

Official title: Short-term Effects of Physical Inactivity on Insulin Sensitivity, Appetite, Energy Balance, and Cardiovascular Responses in Healthy Humans.

Physical inactivity is a significant predictor of major non-communicable diseases such as type 2 diabetes (7%), cardiovascular disease (6%), musculoskeletal disorders and some cancers, and has been proposed to be the 4th leading cause of death worldwide. Reduced physical activity leads to an impaired function of the hormone insulin and increased adiposity. Thus, the elimination of physical inactivity would remove between 6% and 10% of the major non-communicable diseases and increase life expectancy. The aim of the study is to investigate the effects of a short-term (2-day) period of reduced physical activity, with and without a proportional decrease in energy intake, on the action of insulin to regulate blood sugar fluctuations, appetite, and cardiovascular parameters (heart rate, cardiac output, stroke volume, blood flow, arterial blood pressure, peripheral vascular resistance) in response to food ingestion.

What participants receive

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

  • ControlOther

    Normal physical activity and standard energy intake

  • SIT+EOther

    Reduced physical activity and standard energy intake

  • SIT=EOther

    Reduced physical activity and reduced energy intake

Study groups in NCT04172090
Study groupRoleWhat they receive
ControlOther2 consecutive days of standardised daily levels of moderate physical activity (PAL=1.85 reflecting their habitual levels), and matched energy (food) intake
Receives: Other: Control
SIT+EExperimental2 consecutive days of reduced physical activity induced by prolonged periods of sitting (PAL=1.4) whilst maintaining the level of food intake prescribed in the Control trial, thus creating a positive energy balance
Receives: Other: SIT+E
SIT=EExperimental2 consecutive days of reduced physical activity induced by prolonged periods of sitting (PAL=1.4) whilst reducing food intake to match the reduction in energy expenditure induced by inactivity, thus maintaining energy balance
Receives: Other: SIT=E

What is being measured

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

  1. The incremental area under curve for Insulin

    The incremental area under curve for Insulin will be calculated using samples collected at 20 minute intervals between baseline and three hours

    Measured: Over three hours from baseline

Secondary outcomes (1)
  1. The incremental area under curve for arterialized whole blood glucose

    The incremental area under curve for arterialized whole blood glucose will be calculated using samples collected at 10 minute intervals between baseline and four hours

    Measured: Over four hours from baseline

Questions about this trial

What is this clinical trial studying?

A study testing SIT+E and SIT=E in people with Sedentary Behavior, run by University of Nottingham at 1 site in United Kingdom.

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 6 inclusion and 8 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 30 Mar 2020. 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 Kingdom. 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?

The incremental area under curve for Insulin (time frame: Over three hours from baseline). 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 30 Mar 2020.
