About

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.

Trial design

Primary purpose: Other

Allocation: Randomized

Interventional model: Crossover Assignment

Masking: Single Blind

---

30 participants in 2 patient groups

Exercise and Meal (EX)

Experimental group

Description:

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.

Treatment:

Behavioral: Exercise and Meal (EX)

No-Exercise and Meal (NEX)

Experimental group

Description:

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)

Treatment:

Behavioral: No-Exercise and Meal (NEX)
