BACKGROUND
Recent studies indicate that participation in exercise-related games can improve executive function, attention processing, and visuospatial skills.
OBJECTIVE
The aim of this study was to investigate whether exercise via exergaming (EXG) can improve executive function in patients with metabolic syndrome (MetS).
METHODS
A total of 22 MetS patients were recruited and randomly assigned to an EXG group or a treadmill exercise (TE) group. The reaction time (RT) and electrophysiological signals from the frontal (Fz), central (Cz), and parietal (Pz) cortices were collected during a Stroop task after 12 weeks of exercise.
RESULTS
During the Stroop congruence (facilitation) judgment task, both the EXG and TE groups showed significantly faster RT after 12 weeks of exercise training. For N200 amplitude, the EXG group demonstrated significantly increased electrophysiological signals from the Fz and Cz cortices. These changes were significantly larger in the EXG group than in the TE group. Separately, for the P300 amplitude, the EXG groups presented significantly increased electrophysiological signals from the Fz, Cz, and Pz cortices, whereas the TE group showed significantly increased electrophysiological signals from the Cz and Pz cortices only. During the Stroop incongruence (interference) judgment task, both the EXG and TE groups showed significantly faster RT. For P300 amplitude, the EXG group had significantly increased electrophysiological signals from the Fz and Cz cortices only, whereas the TE group had significantly increased electrophysiological signals from the Fz, Cz, and Pz cortices.
CONCLUSIONS
EXG improves executive function in patients with MetS as much as normal aerobic exercise does. In particular, a unique benefit of EXG beyond increased aerobic capacity is the improved selective attention among cognitive functions. Thus, EXG could be recommended to someone who needs to improve their brain responses of concentration and judgment as well as physical fitness.
TRIAL REGISTRATION
ClinicalTrials.gov NCT04015583; https://clinicaltrials.gov/ct2/show/NCT04015583.
背景
近期研究表明，参与与运动相关的游戏可改善执行功能、注意力处理和视觉空间技能。
目的
本研究旨在调查通过运动游戏（EXG）进行锻炼是否能改善代谢综合征（MetS）患者的执行功能。
方法
共招募了22名MetS患者，并将其随机分为EXG组或跑步机运动（TE）组。在运动12周后的Stroop任务中，收集反应时间（RT）以及额叶（Fz）、中央（Cz）和顶叶（Pz）皮质的电生理信号。
结果
在Stroop一致性（促进）判断任务中，EXG组和TE组在运动训练12周后反应时间均显著加快。对于N200波幅，EXG组额叶和中央皮质的电生理信号显著增加。EXG组的这些变化明显大于TE组。另外，对于P300波幅，EXG组额叶、中央和顶叶皮质的电生理信号显著增加，而TE组仅中央和顶叶皮质的电生理信号显著增加。在Stroop不一致性（干扰）判断任务中，EXG组和TE组的反应时间均显著加快。对于P300波幅，EXG组仅额叶和中央皮质的电生理信号显著增加，而TE组额叶、中央和顶叶皮质的电生理信号显著增加。
结论
EXG改善MetS患者执行功能的效果与正常有氧运动相当。特别是，EXG除了提高有氧能力外的一个独特益处是改善了认知功能中的选择性注意力。因此，EXG可推荐给需要改善大脑注意力和判断力反应以及身体素质的人群。
