BACKGROUND
Although emerging research is demonstrating the potential health impact of exergaming, investigations have primarily been conducted in laboratory settings among small samples with short-term interventions. Information on the effectiveness of exergaming in underserved children's objective physical activity (PA) in population-based settings is also scarce. Moreover, most empirical studies have only included 1 type of exergame in the intervention. Therefore, this study's purpose was to investigate the long-term impact of a multigame exergaming intervention among underserved children integrated within school curricula. Specifically, this study examined the effect of exergaming on children's accelerometer-determined sedentary behavior (SB), light PA, moderate-to-vigorous PA (MVPA), and energy expenditure (EE) over 2 years as compared with regular physical education (PE) classes.
METHODS
A total of 261 second- and third-grade children (134 girls, 127 boys; mean age 8.27 years) were recruited from 2 Texas elementary schools. Children's pre-test 3-day SB, light PA, MVPA, and EE at school were assessed in the fall of 2012. Participants were assigned to 1 of 2 groups: (1) exergaming/PE group (125 min weekly of exergaming-based PA program) and (2) comparison group (125 min weekly of PE). PA (SB, light PA, and MVPA) and EE outcome variables were assessed again in 2013 (post-test) and 2014 (follow-up).
RESULTS
Significant time effects were observed for SB ((1, 162) = 25.0, <0.01, = 0.14), light PA ((1, 162) = 9.6, < 0.01, = 0.06), and MVPA ((1, 162) = 6.2, = 0.01, = 0.04) but not for EE ((1, 162) = 0.63, > 0.05, = 0.004). Subsequent pairwise comparisons revealed significant increases from pre- to post-test for light PA (<0.01), MVPA (<0.01), and EE ( = 0.02) with no changes in SB ( > 0.05). Conversely, significant decreases occurred in light PA (<0.01) from post-test to follow-up with no differences seen in MVPA ( = 0.08) and EE ( = 0.06) over the same time period. A significant increase was seen, however, for SB from post-test to follow-up.
CONCLUSION
Exergaming PE can have the same positive effect on children's light PA, MVPA, and EE as regular PE. More research is necessary to discern how to promote long-term PA participation after conclusion of the intervention.
背景
尽管新出现的研究表明了运动游戏对健康的潜在影响，但相关调查主要是在实验室环境中针对小样本进行的短期干预。关于运动游戏在以人群为基础的环境中对服务不足儿童的客观身体活动（PA）有效性的信息也很匮乏。此外，大多数实证研究在干预中只纳入了一种类型的运动游戏。因此，本研究的目的是调查在学校课程中融入多种运动游戏的干预措施对服务不足儿童的长期影响。具体而言，本研究考察了与常规体育课相比，运动游戏在两年内对儿童通过加速度计测定的久坐行为（SB）、轻度身体活动（PA）、中度至剧烈身体活动（MVPA）和能量消耗（EE）的影响。
方法
从德克萨斯州的2所小学招募了总共261名二、三年级儿童（134名女孩，127名男孩；平均年龄8.27岁）。2012年秋季评估了儿童在学校的3天预测试SB、轻度PA、MVPA和EE。参与者被分配到2组中的1组：（1）运动游戏/体育组（每周125分钟基于运动游戏的PA项目）和（2）对照组（每周125分钟体育课）。2013年（后测试）和2014年（随访）再次评估PA（SB、轻度PA和MVPA）和EE结果变量。
结果
观察到SB（（1, 162） = 25.0，<0.01，η² = 0.14）、轻度PA（（1, 162） = 9.6，<0.01，η² = 0.06）和MVPA（（1, 162） = 6.2， = 0.01，η² = 0.04）有显著的时间效应，但EE（（1, 162） = 0.63，>0.05，η² = 0.004）没有。随后的成对比较显示，从预测试到后测试，轻度PA（<0.01）、MVPA（<0.01）和EE（ = 0.02）显著增加，SB没有变化（>0.05）。相反，从后测试到随访，轻度PA显著下降（<0.01），同一时期MVPA（ = 0.08）和EE（ = 0.06）没有差异。然而，从后测试到随访，SB有显著增加。
结论
运动游戏体育课对儿童的轻度PA、MVPA和EE可以产生与常规体育课相同的积极影响。需要更多研究来确定在干预结束后如何促进长期的PA参与。
