A diagnosis of autism spectrum disorder (ASD) and stereotypy engagement is associated with reduced physical activity (PA). Beyond health benefits, researchers have also reported decreases in stereotypy and corresponding increases in on-task behavior in individuals with ASD following PA. However, the duration of reported PA varies among studies examining these effects and the persistence of any effect is not well understood. Furthermore, no previous study examining these effects has reported difficulty evoking adequate durations of PA. The purposes of this study were to (1) develop an intervention to increase PA engagement, (2) analyze changes in stereotypy and on-task behavior following PA, and (3) assess persistence of changes as a function of PA duration. Four participants with ASD were observed for 10 min before, between 1 and 15 min during, and 30 min following PA. Results demonstrated that some duration of PA decreased stereotypy and increased on-task behavior for most participants.

自闭症谱系障碍儿童增加体力活动并参数化分析对刻板印象的影响

自闭症谱系障碍 (ASD) 和刻板印象参与的诊断与体力活动 (PA) 减少有关。除了健康益处外，研究人员还报告说，PA 后 ASD 患者的刻板印象减少，任务行为相应增加。然而，报告的 PA 持续时间在检查这些影响的研究中有所不同，并且任何影响的持续性尚不清楚。此外，以前没有研究过这些影响的研究报告难以唤起足够的 PA 持续时间。本研究的目的是（1）开发一种干预措施以增加 PA 参与度，（2）分析 PA 后刻板印象和任务行为的变化，以及（3）评估变化的持续性作为 PA 持续时间的函数。之前观察了四名患有 ASD 的参与者 10 分钟，期间 1 到 15 分钟，和 PA 后 30 分钟。结果表明，对于大多数参与者来说，一定时间的 PA 降低了刻板印象并增加了任务行为。
