BACKGROUND
Excess post-exercise oxygen consumption (EPOC) of children could indicate the potential of an exercise therapy to treat or prevent obesity. However, EPOC as a result of playing active video games (AVG) has been poorly investigated. Therefore, we aimed to investigate the rapid component of EPOC of children with healthy weight and overweight/obesity (according to their BMI percentile) after playing AVGs that feature predominately upper body (UB) and whole-body (WB) movement.
METHODS
Twenty-one children with healthy weight (BMI percentile < 85%) and with overweight/obesity (BMI percentile ≥ 85%) randomly underwent two 10-min AVG sessions (UB and WB). The heart rate (HR), minute ventilation (VE), oxygen consumption (VO) and carbon dioxide production (VCO) were recorded during exercise and post-exercise recovery period. For the rapid component of EPOC in each AVG session, measurements were recorded every 15 s for 5-min of post-exercise recovery. The rate of perceived exertion (RPE) was also measured immediately before and after each AVG play.
RESULTS
Children with overweight/obesity had a higher average of absolute VE, VO, and VCO than their healthy-weight counterparts (BMI percentile < 85%; n = 21) during post-exercise recovery. RPE, HR, and HR% were not different between the game sessions and weight groups. Children with overweight/obesity showed a higher absolute VO during EPOC than healthy-weight children in both game sessions, but relative VO was higher in healthy-weight children during EPOC. No differences were observed for EPOC between UB and WB sessions.
CONCLUSIONS
Children with overweight/obesity had a greater EPOC than healthy-weight children after AVG sessions in terms of absolute oxygen values, whereas healthy-weight children have higher EPOC considering relative VO when controlling for body mass. UB and WB AVGs induced a similar EPOC among children with healthy weight and overweight/obesity. As UB and WB AVGs induce the rapid component of EPOC in children regardless their weight status, AVGs could be used as an exercise method to treat and prevent child obesity.
背景
儿童运动后过量耗氧量（EPOC）可表明运动疗法治疗或预防肥胖的潜力。然而，对于主动视频游戏（AVG）引起的 EPOC 研究甚少。因此，我们旨在研究健康体重和超重/肥胖（根据 BMI 百分位数）儿童在玩主要涉及上半身（UB）和全身（WB）运动的 AVG 后，EPOC 的快速成分。
方法
21 名健康体重（BMI 百分位数<85%）和超重/肥胖（BMI 百分位数≥85%）的儿童随机进行两次 10 分钟的 AVG 测试（UB 和 WB）。在运动和运动后恢复期记录心率（HR）、分钟通气量（VE）、耗氧量（VO）和二氧化碳产生量（VCO）。对于每个 AVG 会话的 EPOC 快速成分，在运动后恢复期的 5 分钟内，每 15 秒记录一次测量值。在每次 AVG 游戏前后还测量了感觉用力程度（RPE）。
结果
在运动后恢复期，超重/肥胖儿童的平均绝对 VE、VO 和 VCO 均高于健康体重儿童（BMI 百分位数<85%；n=21）。游戏会话和体重组之间的 RPE、HR 和 HR%没有差异。在两个游戏会话中，超重/肥胖儿童的 EPOC 期间绝对 VO 均高于健康体重儿童，但相对 VO 较高的是健康体重儿童。UB 和 WB 游戏会话之间的 EPOC 没有差异。
结论
与健康体重儿童相比，超重/肥胖儿童在玩 AVG 游戏后，绝对氧值的 EPOC 更高，而当控制体重时，健康体重儿童的 EPOC 相对 VO 更高。健康体重和超重/肥胖儿童玩 UB 和 WB AVG 会引起相似的 EPOC。由于 UB 和 WB AVG 会引起儿童 EPOC 的快速成分，无论其体重状况如何，AVG 都可以用作治疗和预防儿童肥胖的运动方法。
