Increasing physical activity and reducing sedentary behaviour form a large part of the treatment of paediatric obesity. However, many children today spend prolonged periods of time playing sedentary video games. Active video games (AVGs) represent a novel and child friendly form of physical activity.
To measure the energy cost of playing two AVGs in children with obesity and healthy age- and gender-matched children.
The energy cost of gaming and heart rates achieved during gaming conditions were compared between groups.
AVG play can result in light-to-moderate intensity physical activity (2.7-5.4 metabolic equivalents). When corrected for fat-free mass those with obesity expended significantly less energy than healthy weight peers playing Nintendo Wii Fit Free Jogging (P = 0.017). No significant difference was seen between groups in the energy cost of playing Boxing.
Certain AVGs, particularly those that require lower limb movement, could be used to increase total energy expenditure, replace more sedentary activities, or achieve moderate intensity physical activity among children with obesity. There seems to be some differences in how children with obesity and children of a healthy weight play AVGs. This could result in those with obesity expending less energy than their lean peers during AVG play.
增加体力活动和减少久坐行为是小儿肥胖症治疗的重要组成部分。然而，如今许多儿童长时间玩久坐不动的电子游戏。主动式电子游戏（AVG）是一种新颖且适合儿童的体力活动形式。
测量肥胖儿童以及年龄和性别匹配的健康儿童玩两种AVG时的能量消耗。
比较不同组在游戏状态下的游戏能量消耗和心率。
玩AVG可导致轻度至中度强度的体力活动（2.7 - 5.4代谢当量）。校正去脂体重后，肥胖儿童玩任天堂Wii Fit自由慢跑游戏时消耗的能量明显低于健康体重的同龄人（P = 0.017）。两组玩拳击游戏时的能量消耗无显著差异。
某些AVG，特别是那些需要下肢运动的游戏，可用于增加肥胖儿童的总能量消耗，取代更多久坐活动，或使其达到中度强度的体力活动。肥胖儿童和健康体重儿童玩AVG的方式似乎存在一些差异。这可能导致肥胖儿童在玩AVG时比瘦的同龄人消耗更少的能量。
