High-intensity Interval Exercise and Chocolate Milk on Blood Glucose and Cognition

9 augustus 2018 bijgewerkt door: Nick Bellissimo, Ryerson University

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.

Studie Overzicht

Gedetailleerde beschrijving

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.

Maatregel Beschrijving
Tijdsspanne
Change from baseline Glycemic Response
Tijdsspanne: baseline (-20 min), and 10, 30, 60, and 90 min post-drink consumption
Blood samples will be collected via finger-prick method to assess glycemic response (blood glucose, mmol/L)
baseline (-20 min), and 10, 30, 60, and 90 min post-drink consumption
Change from baseline verbal declarative memory
Tijdsspanne: baseline (-20 min), and 10, 30, 60, and 90 min post-drink consumption
Cognitive function test of verbal declarative memory
baseline (-20 min), and 10, 30, 60, and 90 min post-drink consumption
Change from baseline working memory
Tijdsspanne: baseline (-20 min), and 10, 30, 60, and 90 min post-drink consumption
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.

Change from baseline executive functioning
Tijdsspanne: baseline (-20 min), and 10, 30, 60, and 90 min post-drink consumption
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.
