Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
We are using an experimental approach, whereby 72 young men are randomised to one of three groups: watching TV, playing the non-violent video game 'FIFA2013', or playing the violent video game 'Call of Duty'. All participants must already have some experience playing the two games, so that whichever group they are assigned to, they can comply with the protocol.
Participants arrive after an overnight fast, and are given a standardised breakfast (a muffin, approx 300 kcal, and a glass of water). After measurements of weight, height and waist girth, they then are assigned to one of the three groups, and allowed to familiarise themselves with the games console or TV. Baseline data on blood pressure (in triplicate, Accutor digital monitor), heart rate (Polar monitor) and appetite/mood (visual analogue scale) are collected, along with a saliva sample for measurement of the 'stress' hormone, cortisol, as well as satiety hormones sich as leptin and ghrelin. We will collect these data again at 4 time-points during the one hour game-playing session, by pausing the game or TV for 4 minutes at 15, 30, 45 and 60 minutes after the session starts.
At the end of the study, we allow the participants half an hour of rest, during which they can choose from a variety of sweet or savoury snacks or fruit, and several drinks.
We will compare the data from the three groups, to test whether changes in blood pressure, heart rate, appetite/mood and salivary hormones, as well as snack consumption, are greater in the group playing the violent game.
