About this study

Official title: The Effects of High-intensity Interval Exercise and Chocolate Milk on Glycemic Control and Cognitive Function in Children.

The purpose of this study is to determine the separate and combined effects of high-intensity interval exercise and chocolate milk on glycemic response, cognitive function, subjective appetite, and salivary cortisol among children aged 9-13 year old children.

Read the detailed description

Twenty children 9-13 years of age will be recruited for this study. On four separate mornings, after a 10 hour overnight fast, each child will consume a standardized breakfast (including orange juice, a strawberry breakfast bar and a pear fruit cup) at home. Using a 2x2 factorial design, 2 hours after breakfast consumption, each participant will arrive in the lab (T=-20 min) and participate in high-intensity interval exercise or sit quietly for 20 min, followed by a treatment drink of chocolate milk or water (control) consumption in 10 min. During high-intensity interval exercise treatment, children will exercise on a cycle ergometer with a 3-min warm-up, 7 repeated bouts of 60-sec exercise at 90% of peak power output and 60-second recovery, and a 3-min cool down. Blood glucose will be measured via finger-prick at baseline (-20 min), 10, 30, 60, and 90 min. Cognitive functions will be measured using a battery of cognitive tests which assess verbal declarative memory, working memory, and executive functioning, and will be measured at baseline, 10. 30. 60, and 90 min. Subjective appetite and emotions will be measured using a 100-mm visual analogue scale (VAS) at baseline, 10, 30, 60, and 90 min. Salivary cortisol will be assessed from saliva samples collected using the passive drool method, and will be collected at baseline, 10 and 30 min.

What is being measured

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

  1. Change from baseline Glycemic Response

    Blood samples will be collected via finger-prick method to assess glycemic response (blood glucose, mmol/L)

    Measured: baseline (-20 min), and 10, 30, 60, and 90 min post-drink consumption

  2. Change from baseline verbal declarative memory

    Cognitive function test of verbal declarative memory

    Measured: baseline (-20 min), and 10, 30, 60, and 90 min post-drink consumption

  3. Change from baseline working memory

    The n-back test consists of 2 levels, 1-back and 2-back, where letters are presented on the screen one at a time. During the 1-back level, participants need to determine if the presented letter is the same as the one letter presented 1 before it or not (by selected 'match' or 'no match' on the side of the screen) and during 2-back need to do determine if it is the same letter as the one presented 2 letters prior.

    Measured: baseline (-20 min), and 10, 30, 60, and 90 min post-drink consumption

  4. Change from baseline executive functioning

    The Stroop test consists of one word appearing on the screen written in either blue, red, yellow or green. There are 24 congruent trials where the presented word is the name of the colour it is written it (i.e. 'red' appearing in the colour red), 24 incongruent trials where the word written is a colour word different from the one it is written in (i.e. 'red' appearing in the colour green), and 10 neutral trials where non-colour words appear (i.e. 'tape' appearing in yellow). The participant is asked to tap the corresponding colour that the word is written in as quickly as possible.

    Measured: baseline (-20 min), and 10, 30, 60, and 90 min post-drink consumption

Secondary outcomes (14)
  1. Change from baseline salivary cortisol response

    Saliva samples will be collected via passive drool method to assess salivary cortisol response (ug/dL)

    Measured: baseline (-20 min), and 10 and 30 min post-drink consumption

  2. Change form baseline Subjective Appetite

    100-mm Visual Analogue Scales (VAS) will be used to assess appetite

    Measured: baseline (-20 min), and 10, 30, 60, and 90 min post-drink consumption

  3. Change from baseline aggression

    100-mm Visual Analogue Scales (VAS) will be used to assess aggression

    Measured: baseline (-20 min), and 10, 30, 60, and 90 min post-drink consumption

  4. Change from baseline anger

    100-mm Visual Analogue Scales (VAS) will be used to assess anger

    Measured: baseline (-20 min), and 10, 30, 60, and 90 min post-drink consumption

  6. Change from baseline disappointment

    100-mm Visual Analogue Scales (VAS) will be used to assess disappointment

    Measured: baseline (-20 min), and 10, 30, 60, and 90 min post-drink consumption

    100-mm Visual Analogue Scales (VAS) will be used to assess happiness

    Measured: baseline (-20 min), and 10, 30, 60, and 90 min post-drink consumption

  8. Change from baseline upset

    100-mm Visual Analogue Scales (VAS) will be used to assess upset

    Measured: baseline (-20 min), and 10, 30, 60, and 90 min post-drink consumption

  9. Change form baseline frustration

    100-mm Visual Analogue Scales (VAS) will be used to assess frustration

    Measured: baseline (-20 min), and 10, 30, 60, and 90 min post-drink consumption

  10. Change from baseline alertness

    100-mm Visual Analogue Scales (VAS) will be used to assess alertness

    Measured: baseline (-20 min), and 10, 30, 60, and 90 min post-drink consumption

  11. Change from baseline sadness

    Measured: baseline (-20 min), and 10, 30, 60, and 90 min post-drink consumption

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 4 inclusion and 4 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 10 Aug 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 Canada. 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?

Change from baseline Glycemic Response (time frame: baseline (-20 min), and 10, 30, 60, and 90 min post-drink consumption). The study lists 4 primary outcomes in all. 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 NCT03305107, 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 10 Aug 2018.
