Although promoted for weight loss, especially in young adults, it has yet to be determined if the physical activity energy expenditure (PAEE) and intensity of the newest active video games (AVGs) qualifies as moderate-to-vigorous physical activity (MVPA; > 3.0 METs). This study compared the PAEE and intensity of AVGs to traditional seated video games (SVGs).
Fifty-three young adults (18-35 y; 27 females) volunteered to play 6 video games (4 AVGs, 2 SVGs). Anthropometrics and resting metabolism were measured before testing. While playing the games (6-10 min) in random order against a playmate, the participants wore a portable metabolic analyzer for measuring PAEE (kcal/min) and intensity (METs). A repeated-measures ANOVA compared the PAEE and intensity across games with sex, BMI, and PA status as main effects.
The intensity of AVGs (6.1 ± 0.2 METs) was significantly greater than SVGs (1.8 ± 0.1 METs). AVGs elicited greater PAEE than SVGs in all participants (5.3 ± 0.2 vs 0.8 ± 0.0 kcal/min); PAEE during the AVGs was greater in males and overweight participants compared with females and healthy weight participants (p's < .05).
The newest AVGs do qualify as MVPA and can contribute to the recommended dose of MVPA for weight management in young adults.
尽管新型活跃视频游戏（AVG）被宣传有助于减肥，尤其是对年轻人而言，但尚不清楚其身体活动能量消耗（PAEE）及强度是否符合中度至剧烈身体活动（MVPA；> 3.0代谢当量）的标准。本研究比较了AVG与传统静态视频游戏（SVG）的PAEE及强度。
五十三名年轻成年人（18 - 35岁；27名女性）自愿参与6款视频游戏（4款AVG，2款SVG）的游玩。在测试前测量人体测量学指标和静息代谢率。在与玩伴随机顺序游玩游戏（6 - 10分钟）时，参与者佩戴便携式代谢分析仪以测量PAEE（千卡/分钟）和强度（代谢当量）。采用重复测量方差分析比较不同游戏间的PAEE及强度，以性别、BMI和身体活动状态作为主要效应因素。
AVG的强度（6.1 ± 0.2代谢当量）显著高于SVG（1.8 ± 0.1代谢当量）。所有参与者中，AVG引发的PAEE均高于SVG（5.3 ± 0.2 vs 0.8 ± 0.0千卡/分钟）；与女性和体重正常的参与者相比，男性和超重参与者在玩AVG时的PAEE更高（p值 < 0.05）。
最新的AVG确实符合MVPA标准，可为年轻人体重管理中推荐的MVPA剂量做出贡献。
