Determinants of Post-Exercise Eating Patterns (DEEP)

23. července 2019 aktualizováno: 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.

Skupina účastníků / Arm
Intervence / Léčba
Experimentální: 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.
30 minute acute bout of high intensity intermittent exercise followed by ad-libitum meal
Experimentální: 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)
30 minute non-exercise period where participants will be watching a video/movie followed by ad-libitum meal
