Study summary

Individuals with pre-diabetes or diabetes would benefit from low impact methods that would improve their insulin sensitivity and aid in maintaining glucose homeostasis. Physical activity helps the body decrease its insulin resistance and burn excess sugar. Many diabetics also suffer from obesity and specific forms or durations of physical exercise may not be viable options for these individuals. Determining whether short bursts of moderate exercise improve blood glucose levels in healthy humans may identify a further method for diabetics to improve their glucose homeostasis.

The aim of this study is to determine the most effective moderate exercise that can be completed in 3 minutes and its effectiveness on improving glucose handling, in response to a single day of standardized high-fat and high-carbohydrate feeding in comparison to periods of prolonged sitting.

In context

Sedentary Behavior

1,273 studies on the registry are indexed under Sedentary Behavior; 300 are open to participants now.

This study's enrollment of 6 is below the median of 60 across 1,076 interventional studies indexed under Sedentary Behavior.

  • between 18-30 kg/m²
  • non-smoker

Exclusion criteria

Exclusion Criteria:

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Study arms

  • No intervention
    Control

    No intervention. Study participants will be seated during the entire sedentary 3-hour time period and wheeled to phlebotomy (and exercise) stations when required. During the sedentary period, participants will eat the food according to the study protocol and be seated at desks and allowed to read and use computers.

  • Experimental
    Intervention

    Will disrupt their sedentary time with 3 minute exercise sessions every 30 minutes

    Other: Activity/Moderate Exercise

Interventions

  • OtherActivity/Moderate Exercise

    3-hour sedentary period with 3 minute activity breaks of moderate exercise every 30 minutes

What researchers measure

Primary outcomes

  1. Change in Insulin levels

    The change in blood insulin levels from baseline (12 hours fasted) to 3-hours post-prandial will be determined from blood serum using a human metabolic hormone multiplex panel (Luminex xMAP technology).

    Time frame: Pre-prandial baseline (12 hours fasted) and 3 hours post-prandial on each of two testing days

  2. Change in concentration of C-peptide

    The change in blood C-peptide levels from baseline (12 hours fasted) to 3-hours post-prandial will be determined from blood serum using a human metabolic hormone multiplex panel (Luminex xMAP technology).

    Time frame: Pre-prandial baseline (12 hours fasted) and 3 hours post-prandial on each of two testing days

  3. Changes in blood glucose levels

    Blood glucose levels will be determined at pre-prandial baseline and over the following 3-hour testing period using hand-held blood glucose meters.

    Time frame: Baseline and every 30-60 minutes over 3 hours (6 timepoints per test day)

  4. Change in metabolomic response to a test meal

    Targeted metabolomics analysis of approximately 139 metabolites in blood serum by LC-MS/MS to generate a metabolomic profile in response to a high-fat and high-carbohydrate test meal. Metabolites to be determined are categorized as biogenic amines, amino acids, histidines, carboxylic acids, acylcarnitines, glycerophospholipids and organic acids.

    Time frame: Pre-prandial and 3-hours post test meal through study completion

Secondary outcomes

  1. Immediate effects of short-term sedentary behaviour on cognitive function

    Assessing cognitive abilities using the Stroop Test.

    Time frame: 3 hours post-activity (sedentary behaviour or exercise) on test days through study completion

  2. Immediate effects of short-term sedentary behaviour on cognitive function

    Assessing cognitive abilities using the Iowa Trail Making Test.

    Time frame: 3 hours post-activity (sedentary behaviour or exercise) on test days through study completion

  3. Immediate effects of short-term sedentary behaviour on cognitive function

    Assessing cognitive abilities using the Digit-Span test.

    Time frame: 3 hours post-activity (sedentary behaviour or exercise) on test days through study completion

  4. Immediate effects of short-term sedentary behaviour on cognitive function

    Assessing cognitive abilities using the N-back test.

    Time frame: 3 hours post-activity (sedentary behaviour or exercise) on test days through study completion

  5. Immediate effects of short-term sedentary behaviour on cognitive function

    Assessing cognitive abilities using the Flankers test.

    Time frame: 3 hours post-activity (sedentary behaviour or exercise) on test days through study completion

  6. Gene expression levels in isolated PBMC populations

    Determining changes in gene expression in pathways associated with RAGE signalling.

    Time frame: Pre-prandial and 3 hours post-prandial on on test days through study completion

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 29, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
