A Quantitative Evaluation of User Benefits When Using a Sit-and-Stand Desk With a Gamified Auto-Elevate Feature

随着科技的发展和电脑的日益普及，发达经济体中人们在久坐不动的工作场所花费的时间急剧增加（Matthews et al., 2008）。久坐行为的特征是清醒时的能量消耗=1.5代谢当量（Tremblay等人，2017），并且与健康风险相关，包括心血管特异性死亡率和总体死亡率的增加（Young Deborah Rohm等人，2016）。久坐的影响与代谢综合征、心血管疾病、高血压、2型糖尿病、静脉血栓形成、下背部疼痛和肌肉疲劳有关（Young Deborah Rohm et al., 2016）。根据流行病学证据，一个专家委员会建议，至少25%到50%的工作时间应该是站立的，这些时间应该在工作日间隔（Buckley et al., 2015）。在考虑使用坐立两用办公桌时，对最有益的站立量和坐立两用的次数进行了充分研究（Chambers et al., 2019）。该领域的研究仍在继续（Bao & Lin, 2018; Black et al., 2015, 2019），需要确保这些研究在日常工作环境中适用。其中一个挑战是激励人们在不适发生之前认识到改变姿势的必要性。在电脑屏幕上显示的提醒可能是有帮助的（Barbieri等人，2017；Sharma等人，2019），但可以忽略。这些提醒的游戏化可能会增加用户的动机，更有效地让用户享受最有益的频繁的姿势变化。该项目将研究在使用Ergonomyx创建的用于各种坐立高度可调工作站的游戏化自动提升功能时，坐下和站立之间的游戏化常规姿势变化的作用，以及员工幸福感和绩效的改善。

With the technological development and increasing ubiquitous use of computers, the amount of time people in developed economies spend in sedentary workplaces has increased dramatically (Matthews et al., 2008). Sedentary behavior is characterized by an energy expenditure =1.5 metabolic equivalents (METs) while awake (Tremblay et al., 2017), and has been associated with health risks including increased cardiovascular-specific and overall mortality (Young Deborah Rohm et al., 2016). Effects of prolonged sitting have been associated with metabolic syndrome, cardiovascular disease, hypertension, Type 2 diabetes, Venous thrombosis, Lower Back pain and Muscle fatigue (Young Deborah Rohm et al., 2016). A committee of experts has suggested that at least 25% and as much as 50% of the work day should be spent standing with those periods being spaced over the workday, based on epidemiological evidence (Buckley et al., 2015). When considering use of sit-stand desks, the amount of standing which is most beneficial and number of sit-stand changes has been understudied (Chambers et al., 2019). Research in this field continues (Bao & Lin, 2018; Black et al., 2015, 2019) with a need to ensure such studies are applicable users in their regular work environment. One of the challenges is to motivate people to recognize the need to change their posture before discomfort occurs. Reminders may be presented on a computer screen are helpful (Barbieri et al., 2017; Sharma et al., 2019) but can be ignored. Gamification of these reminders may be increase user motivation and be more effective at making users enjoy the most beneficial frequent postural changes. This project will study the role of a gamified regular postural changes between sitting and standing degree of changes and improvements in employee well-being and performance when using a gamified Auto-Elevate feature created by Ergonomyx for use with various sit-stand height adjustable workstations.
