Sedentary behavior at work contributes to detrimental cognitive outcomes (e.g., decreases in attention). The length of time that cognitive performance benefits are sustained following bouts of breaking up sitting (e.g., using sit-stand desks or walking) is not known. A narrative review of the literature was conducted using a systematic search strategy, with keywords related to breaking up sitting interventions in office-based environments and cognitive performance outcomes in the period immediately post the cessation of the breaking up sitting intervention. Three types of office-based breaking up sitting interventions were identified; 1) sit-stand desks, 2) walking desks and 3) cycling desks. From the eight studies which met the criteria, the impacts of these interventions on cognitive performance outcomes were mixed, with significant benefits in some studies and others reporting no benefit. Of the cognitive domains assessed, working memory, attention, and psychomotor function showed significant sustained improvement for up to 30 minutes post intervention. While there are benefits to a key set of cognitive performance domains following breaking up sitting interventions in office-based settings, no studies have evaluated whether benefits to cognitive performance persist for longer than 30 minutes after the breaking up sitting intervention. Furthermore, specific applications of these cognitive benefits to tasks outside of work (e.g., driving home from work) are unknown.
工作时的久坐行为会导致有害的认知结果（例如注意力下降）。打破久坐（如使用坐站两用办公桌或行走）后，认知表现受益的持续时间尚不清楚。采用系统搜索策略对文献进行了叙述性综述，关键词涉及基于办公室环境中的打破久坐干预措施以及打破久坐干预措施停止后紧接着的时间段内的认知表现结果。确定了三种基于办公室的打破久坐干预措施：1）坐站两用办公桌，2）行走办公桌，3）骑行办公桌。在符合标准的八项研究中，这些干预措施对认知表现结果的影响不一，一些研究有显著益处，而另一些研究则报告无益处。在评估的认知领域中，工作记忆、注意力和心理运动功能在干预后长达30分钟内显示出持续的显著改善。虽然在基于办公室的环境中进行打破久坐干预后，一组关键的认知表现领域会有好处，但尚无研究评估打破久坐干预后认知表现的益处是否会持续超过30分钟。此外，这些认知益处对工作以外任务（如下班开车回家）的具体应用尚不清楚。
