OBJECTIVE.我们研究了活动增强屏幕设备对儿童能量消耗的影响，并将其与坐着进行相同活动进行比较。我们的假设是，与久坐不动的电子游戏相比，儿童玩促进活动的电子游戏时的能量消耗会显着增加。研究人员测量了25名8至12岁的儿童的能量消耗，其中15名是瘦人，他们坐着看电视，坐着玩传统的视频游戏，在跑步机上以每小时1.5英里的速度行走时看电视，以及玩促进活动的视频游戏。坐着看电视和玩电子游戏分别使能量消耗增加了20 +/- 13%和22 +/- 12%。当受试者在跑步机上行走并看电视时，能量消耗比静息值增加了138 +/- 40%。对于促进活动的视频游戏，EyeToy（索尼电脑娱乐）的能量消耗增加了108 +/- 40%，Dance Dance Revolution Ultramix 2（科乐美数字娱乐）增加了172 +/- 68%。当久坐屏幕时间转换为活跃屏幕时间时，能量消耗增加一倍以上。这些干预措施可以被考虑用于肥胖症的预防和治疗。
OBJECTIVE. We examined the effect of activity-enhancing screen devices on children's energy expenditure compared with performing the same activities while seated. Our hypothesis was that energy expenditure would be significantly greater when children played activity-promoting video games, compared with sedentary video games.METHODS. Energy expenditure was measured for 25 children aged 8 to 12 years, 15 of whom were lean, while they were watching television seated, playing a traditional video game seated, watching television while walking on a treadmill at 1.5 miles per hour, and playing activity-promoting video games.RESULTS. Watching television and playing video games while seated increased energy expenditure by 20 +/- 13% and 22 +/- 12% above resting values, respectively. When subjects were walking on the treadmill and watching television, energy expenditure increased by 138 +/- 40% over resting values. For the activity-promoting video games, energy expenditure increased by 108 +/- 40% with the EyeToy (Sony Computer Entertainment) and by 172 +/- 68% with Dance Dance Revolution Ultramix 2 (Konami Digital Entertainment).CONCLUSIONS. Energy expenditure more than doubles when sedentary screen time is converted to active screen time. Such interventions might be considered for obesity prevention and treatment.
