Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
Ad-libitum amount of food consumed in response to experimental condition: exercise or rest (no exercise).
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)
3 hours
Secondary Outcomes (8)
Appetite-related blood hormone concentration in response to experimental conditions.
3 hours
Metabolic blood variable concentration in response to experimental conditions
3 hours
Subjective ratings of hunger in response to experimental conditions
3 hours
Subjective ratings of satiation (fullness) in response to experimental conditions
3 hours
Subjective ratings of desire to eat in response to experimental conditions
3 hours
- +3 more secondary outcomes
Other Outcomes (7)
Self-reported tendencies of compensatory health beliefs
Assessed at start of study - through study completion - up to 4-5 weeks
Self-reported tendencies of licensing/reward beliefs
Assessed at start of study - through study completion - up to 4-5 weeks
Self-reported tendencies and motives of compensatory eating behaviour in response to exercise
Assessed at start of study - through study completion - up to 4-5 weeks
- +4 more other outcomes
Study Arms (2)
Exercise and Meal (EX)
EXPERIMENTALThe 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.
No-Exercise and Meal (NEX)
EXPERIMENTALThe 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)
Interventions
30 minute acute bout of high intensity intermittent exercise followed by ad-libitum meal
30 minute non-exercise period where participants will be watching a video/movie followed by ad-libitum meal
