Armi e interventi
Gruppo di partecipanti / Arm |
Intervento / Trattamento |
|---|---|
|
Sperimentale: 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
|
|
Sperimentale: 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

Misura Descrizione |
Lasso di tempo |
|---|---|---|

Self-reported tendencies of compensatory health beliefs
Lasso di tempo: Assessed at start of study - through study completion - up to 4-5 weeks
|
Influence of self-reported tendencies of compensatory health beliefs on the relationship between experimental conditions and study outcomes. Scale to be used: Compensatory Health Belief (CHB) Scale, CHB Subscales: Substance use, Eating/sleeping habits, Stress and Weight regulation, Ratings on a 5-point agreement scale. Greater scores (summed) indicate greater tendency for an individual to hold compensatory beliefs (for the particular domain/subscale or collectively). |
Assessed at start of study - through study completion - up to 4-5 weeks
|
|
Self-reported tendencies of licensing/reward beliefs
Lasso di tempo: Assessed at start of study - through study completion - up to 4-5 weeks
|
Influence of self-reported tendencies of licensing eating behaviour in response to exercise on the relationship between experimental conditions and study outcomes. Scale to be used: Post-Exercise Licensing (PEL)Scale. Ratings on a 7 point agreement scale. Greater scores (averaged) indicate a greater tendency to reward/license in response to exercise. |
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
Lasso di tempo: Assessed at start of study - through study completion - up to 4-5 weeks
|
Influence of self-reported tendencies and motives of compensatory eating behaviour in response to exercise on the relationship between experimental conditions and study outcomes Scale to be used: Compensatory Eating Motives Questionnaire (CEMQ) Subscales: Eating for Reward, Eating for Recovery, Eating for Relief (4 point frequency scale) Greater scores (summation of outcome of respective subscales) indicate greater tendency to compensate due to particular motive (respective subscales). |
Assessed at start of study - through study completion - up to 4-5 weeks
|
|
Self-reported assessment of motivation (regulation) to exercise
Lasso di tempo: Assessed at start of study - through study completion - up to 4-5 weeks
|
To examine the influence of self-reported motivation to exercise on the relationship between experimental conditions and study outcomes. Scale involve: Behavioural Regulation in Exercise Questionnaire (BREQ) measures the stages of the self-determination contin. Subscales: Amotivation, External regulation, Introjected regulation, Identified regulation, Integrated regulation, Intrinsic regulation.Greater scores (averaged of outcome of respective subscale/items) indicate greater tendency for exercise behaviour to be regulated by particular construct (respective subscale). |
Assessed at start of study - through study completion - up to 4-5 weeks
|
|
Self-reported assessment of motivation to eat healthily
Lasso di tempo: Assessed at start of study - through study completion - up to 4-5 weeks
|
To examine the influence of self-reported motivation to adopt healthy eating behaviour on the relationship between experimental conditions and study outcomes. Scale involve: Regulation of Eating Behavioural Scale (REBS). Subscales: Amotivation, External regulation, Introjected regulation, Identified regulation, Integrated regulation, Intrinsic regulation. Greater scores (averaged of outcome of respective subscale/items) indicate greater tendency for eating behaviour to be regulated by particular construct (respective subscale). |
Assessed at start of study - through study completion - up to 4-5 weeks
|
|
Self-reported attitudes towards eating behaviour as assessed by the Three Factor Eating Behaviour Questionnaire (TFEQ-R18)
Lasso di tempo: Assessed at start of study - through study completion - up to 4-5 weeks
|
Influence of self-reported attitudes towards eating on the relationship between experimental conditions and study outcomes. Scale involve: Three Factor Eating Behaviour Questionnaire (TFEQ-R18) Subscales: Dietary Restraint, Uncontrolled Eating, Emotional Eating Greater scores (averaged outcome of respective subscale/items) indicate greater likelihood of the behaviour (of construct measure by respective subscales). |
Assessed at start of study - through study completion - up to 4-5 weeks

Lasso di tempo: Assessed at start of study - through study completion - up to 4-5 weeks
|
Influence of self-reported weight-related behaviour change status on the relationship between experimental conditions and study outcomes. Scale involve: Physical Activity Stages of Change Questionnaire. Scores (based on scoring algorithm) will indicate participants' current stage of motivational readiness for change specific to physical activity. Greater score (1-5 representing five stages of change) indicates physical activity status and intent to be active. |
