Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

The present study will be of a randomised counterbalanced repeated-measures (crossover) design. Each participant (n = 30) will complete four sessions; one initial screening session (remotely administered), one baseline/familiarisation session (first lab visit) and two subsequent experimental sessions (second and third lab visits). The two experimental sessions will follow a similar protocol, except that one condition will involve an exercise protocol before an ad-libitum meal (Exercise and Meal (EX) condition), and the other, a no-exercise period (rest) before an ad-libitum (NEX) control condition.
Primary Study Purpose

OTHER

Blinding Strategy

SINGLE

Participants
Participants are "blind" to the true aim of the study. In addition, assignment of the experimental sessions are administered at random.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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.

Group Type EXPERIMENTAL

Exercise and Meal (EX)

Intervention Type BEHAVIORAL

30 minute acute bout of high intensity intermittent exercise followed by ad-libitum meal

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)

Group Type EXPERIMENTAL

No-Exercise and Meal (NEX)

Intervention Type BEHAVIORAL

30 minute non-exercise period where participants will be watching a video/movie followed by ad-libitum meal
