Effect of Prior Game Experience on Energy Expenditure During Xbox Kinect in Children and Teens

Abstract

To examine the effect of game-specific and overall Kinect experience and overall gaming habits on energy expenditure (EE) and enjoyment of children and adolescents (8-17 years) while playing Xbox® Kinect exergames. Participants (N = 55) played four active videogames for 6-10 minutes. Height, weight, and resting metabolic rate were measured and participants completed a survey on gaming habits and previous experience. Habit (none, low, moderate, or high) was based on the number of game systems at home, frequency, and duration of game play. Game-specific experience was classified as either inexperienced or experienced. A composite score was created for how much experience they had with each game, classified as none, low, or high. The participant wore a portable metabolic analyzer (total and physical activity energy expenditure [PAEE]), heart rate (HR) monitor, and accelerometer (waist, counts/min). Enjoyment was measured after each game using a three-item face scale. Bonferroni-adjusted three-way ANOVA assessed PAEE, intensity, and enjoyment across overall and game-specific experience and habits (P < 0.05). Intensity, PAEE, and HR were greater in experienced versus inexperienced players (5.1 ± 0.2 vs. 4.4 ± 0.2 metabolic equivalents [METs]; 4.1 ± 0.2 vs. 3.3 ± 0.2 kcal/min; 138 ± 2.5 vs. 130 ± 1.9 bpm). Higher game-specific experience levels elicited greater counts/min compared with no experience. Moderate gaming habits elicited greater PAEE and METs than low gaming habits. Enjoyment was equal in all groups. Participants with more game-specific Kinect experience or overall gaming habits elicited greater PA energy and intensity. This study supports that children and adolescents can play Xbox Kinect without decrements in PAEE or enjoyment.
