The influence of subtly encouraging individuals to choose less calorie-dense foods

INTERVENTION: Computer‐generated randomisation into control and experimental groups. All participants complete three questionnaires: baseline (one week before participants' sports match), pre‐match (within one hour before the match) and post‐match (immediately following the match). Control group: no priming intervention applied. Experimental group: The priming intervention is one question in the pre‐match questionnaire, which asks participants to select a low energy‐dense food for post‐match consumption. Post‐match, following questionnaire completion, all participants are asked to select one food item from a selection of three low energy‐dense and three high energy‐dense foods visually displayed on offer (much to the surprise of the experimental group who have been primed to expect a choice of exclusively low energy‐dense options). CONDITION: Promotion of less energy‐dense food selection following exercise in university‐level student athletes, as part of promotion of an overall healthier lifestyle. ; Not Applicable PRIMARY OUTCOME: Energy density of food item selected is measured by the researcher observing whether participants select a low energy‐dense or high energy‐dense food following post‐match questionnaire completion (immediately following participants' sports match) SECONDARY OUTCOME: Self reported appetite is measured using a visual analogue scale (0‐10) before exercise (pre‐match questionnaire) and after exercise (post‐match questionnaire) INCLUSION CRITERIA: Members of the University of St Andrews 1st or 2nd XI, male or female, football or hockey teams.
