Brief Summary
Previous studies have shown that subjects who play video games are prone to consume larger quantities of food than subjects who are simply resting. This is believed to be due to the development of a stress response in the video games group, resulting in increased fuel metabolism. However, it was shown that the energy intake of the two groups showed no correlation with the subjects' appetite/hunger, which was identical in both groups. The investigators propose to explore this issue further by comparing the effects of different types of video games on metabolism, using a randomized controlled trial. In this study, they will compare the stress levels, heart rate, blood pressure, appetite/mood, energy consumption, grip strength, memory and saliva cortisol, leptin and ghrelin levels of subjects playing (a) competitive and (b) problem-solving video games. Measurements will be taken preceding, during and after the 1 hour intervention. Following the intervention, participants will be offered savoury and sweet foods/drinks, which will allow us to assess their appetite preferences and caloric intake. The investigators first aim is to determine whether there is a significant difference in stress levels, eating habits and energy metabolism in the two groups. Our second aim is to determine whether there is a difference in glucose distribution to the muscles and brain between the two groups.
