简要总结
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.

研究组 & 干预措施
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.
干预措施: Exercise and Meal (EX) (Behavioral)
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)
干预措施: No-Exercise and Meal (NEX) (Behavioral)
结局指标
主要结局
Ad-libitum amount of food consumed in response to experimental condition: exercise or rest (no exercise).
时间窗: 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)
次要结局
- Subjective ratings of desire to eat in response to experimental conditions(3 hours)
- Subjective ratings of prospective food consumption in response to experimental conditions(3 hours)
- Subjective ratings of satiation (fullness) in response to experimental conditions(3 hours)
- Appetite-related blood hormone concentration in response to experimental conditions.(3 hours)
- Subjective ratings of hunger in response to experimental conditions(3 hours)
- Metabolic blood variable concentration in response to experimental conditions(3 hours)
- Free-living energy intake (1 day post-experiment) in response to experimental conditions(1 day)
- Free-living physical activity levels intake (1 day post-experiment) in response to experimental conditions(1 day)
