目的：研究长时间站立时是否使用运动干预会影响不适和认知功能。背景：正在试用替代工作姿势来打破办公室工作人员的长时间坐姿，例如站立。长时间站立对健康有潜在的负面影响，包括腰部和下肢不适，并可能影响认知功能。在站立过程中引入运动可能会提供一个健康和富有成效的替代workposture.Method：20名成年参与者进行了实验室研究的2小时的站立和站立与运动（使用脚凳），同时执行计算机工作。不适和认知功能的变化，肌肉疲劳，下背部角度，骨盆运动，下肢肿胀，和精神状态，investigated.Results：不适感随着时间的推移在所有身体区域显着增加。踝关节/足部在不同条件下存在差异（发生率比[95%置信区间]：1.89 [1.10-3.23]），站立运动期间的不适感更高。创造性解决问题的错误在站立运动期间增加，在站立期间减少（时间x条件：= 0.64 [0.10-1.18]），没有其他认知功能测量差异。两种条件下的精神状态均随时间推移而恶化，站立运动时更严重（时间x条件：= 2.44 [0.23-4.66]）。没有显着的相互作用效果被发现为其他outcomevariable.Conclusion：站立与运动提供不舒适或认知功能的优势。有一些负面影响的脚踝/脚的不适和创造性的解决问题。一个替代的脚凳设计和使用协议可能会产生更有利的结果。应用：根据本研究的结果，不建议使用脚凳来提高替代脚强制5分钟的间隔，以帮助管理不适，而长时间站立在工作场所。
Objective: To investigate whether use of a movement intervention when undertaking prolonged standing affected discomfort and cognitive function.Background: Alternate work positions to break up prolonged sitting for office workers are being trialed, such as standing. Prolonged standing has potential negative health implications, including low back and lower limb discomfort, and may influence cognitive function. Introducing movement during standing may provide a healthy and productive alternative work posture.Method: Twenty adult participants undertook a laboratory study of 2 hr of standing and standing with movement (using a footrest) while performing computer work. Changes in discomfort and cognitive function, with muscle fatigue, low back angle, pelvis movement, lower limb swelling, and mental state, were investigated.Results: Discomfort increased significantly over time across all body regions. Ankle/foot differed between conditions (incident rate ratio [95% confidence interval]: 1.89 [1.10-3.23]), with higher discomfort during standing with movement. Creative problem-solving errors increased during standing with movement and decreased during standing (Time x Condition: = 0.64 [0.10-1.18]), with no other cognitive function measure differences. Mental state deteriorated over time for both conditions, greater during standing with movement (Time x Condition: = 2.44 [0.23-4.66]). No significant interaction effects were found for the other outcome variables.Conclusion: Standing with movement provided no advantage in discomfort or cognitive function. There were some negative effects for ankle/foot discomfort and creative problem solving. An alternate footrest design and protocol for use may yield more favorable results.Application: Based on the results from this study, footrest use to raise alternative foot for forced 5-min intervals would not be recommended to assist with managing discomfort while prolonged standing in workplaces.
