Active workstation alternatives (e.g., treadmill desks and pedal desks) have the potential to elevate workplace energy expenditure by replacing occupational sedentary behavior with opportunities to generate low-intensity non-exercise physical activity, but only to the extent that workers find them acceptable and congruent with their primary working tasks and therefore can frequently use them for extended periods of time.
To assess workers' acceptability of the Pennington Pedal Desk™.
Full-time sedentary workers (N = 42; 76% female; mean+SD age 39.6±11.3 years; BMI 25.7±5.4 kg/m2) used the pedal desk for 15 minutes while they: 1) searched the internet, 2) composed an email, and 3) completed acceptability ratings using an online Likert scale anchored from 1/strongly disagree to 5/strongly agree. Garmin Vector power meter pedals and EDGE 510 GPS bike computer (Garmin ®, USA) continuously captured revolutions per minute (RPM) and power.
Participants indicated that they would use the pedal desk for 4 (median) hours per work day and 97.6% of participants were somewhat or completely confident that they could type proficiently while using the pedal desk. Participants pedaled at 54.8±11.2 RPM and 23.1±8.6 watts (mean+SD).
Participants rated the Pennington Pedal Desk™ workstation positively and indicated potential for extended daily use.
主动式工作站替代方案（如跑步机办公桌和脚踏办公桌）有潜力通过用产生低强度非运动性身体活动的机会取代职业久坐行为来提高工作场所的能量消耗，但前提是员工认为它们可以接受，并且与他们的主要工作任务相符，因此能够长时间频繁使用。
评估员工对彭宁顿脚踏办公桌™的可接受性。
全职久坐的员工（N = 42；76%为女性；平均年龄±标准差为39.6±11.3岁；体重指数为25.7±5.4kg/m²）使用脚踏办公桌15分钟，同时进行以下活动：1）上网搜索，2）撰写电子邮件，3）使用从1/强烈不同意到5/强烈同意的在线李克特量表完成可接受性评分。佳明矢量功率计踏板和EDGE 510 GPS自行车电脑（佳明®，美国）持续记录每分钟转速（RPM）和功率。
参与者表示他们每个工作日会使用脚踏办公桌4（中位数）小时，97.6%的参与者或多或少或完全相信他们在使用脚踏办公桌时能够熟练打字。参与者的踩踏转速为54.8±11.2 RPM，功率为23.1±8.6瓦（平均±标准差）。
参与者对彭宁顿脚踏办公桌™工作站给予了积极评价，并表示有每天长时间使用的潜力。
