Determinants of Post-Exercise Eating Patterns (DEEP)

23 juli 2019 uppdaterad av: Aaron Sim, Clinical Nutrition Research Centre, Singapore

Determinants of Post-Exercise Eating Patterns / Alternative Title (Cover): Effect of Pre-meal Activities on Blood Pressure in Healthy Adults

This study examines potential physiological and psychological determinants of food intake in response to exercise. Specifically, beyond measuring actual food consumption and physiological markers typically assessed during exercise and appetite work (i.e. appetite hormones, blood glucose), the investigators wish to investigate the influence of individual behavioural differences (attitudes towards eating, licensing/compensatory health beliefs, self-regulation, and exercise-associated motivation) on the relationship between exercise and eating behaviour.

Vapen och interventioner

Deltagargrupp / Arm
Intervention / Behandling
Experimentell: Exercise and Meal (EX)
The EX protocol will involve a 30 minute acute bout of high intensity intermittent exercise on a stationary exercise bike followed by an ad-libitum test meal.
Beteende: Exercise and Meal (EX)
30 minute acute bout of high intensity intermittent exercise followed by ad-libitum meal
Experimentell: No-Exercise and Meal (NEX)
The NEX protocol will involve a 30 minute period of rest (to match the exercise period in EX) where participants will be provided a video/movie. Following this, participants will be provided ad-libitum access to a test meal (as per EX energy intake assessment protocol)
Beteende: No-Exercise and Meal (NEX)
30 minute non-exercise period where participants will be watching a video/movie followed by ad-libitum meal

Resultatmått
Åtgärdsbeskrivning
Tidsram
Ad-libitum amount of food consumed in response to experimental condition: exercise or rest (no exercise).
Tidsram: 3 hours
Participants' eating behaviour will be assessed by measuring the total amount of the test meal consumed in each experimental condition. The test meal will be provided ad-libitum (i.e. there will be non-restricted access)
