Abstract

BACKGROUND

Workplaces that provide opportunities for physical activity without requiring extra time for activity could help counteract the obesity epidemic. Desk ellipticals can contribute to activity-supportive workplace environments; however, the feasibility of engaging employees in pedaling ellipticals during simultaneous office work has not been well evaluated.

OBJECTIVE

We aim to present the rationale and methods from an ongoing randomized trial with overweight and obese employees that will evaluate (1) the effects of pedaling a compact desk elliptical on work performance and (2) the influence of different incentive types and schedules on desk pedaling quantity.

METHODS

Overweight and obese medical center employees are being recruited in dyads for a 2 (gift card type: healthier food vs Amazon) by 3 (gift card schedule: immediate incentive contingent on individual pedaling quantity; immediate incentive partially contingent on dyads' joint pedaling quantity; and delayed noncontingent pedaling incentive) cluster randomized within-subjects factorial trial. All participants receive a Bluetooth-enabled desk elliptical for 4 weeks and access to a mobile app that provides real-time pedaling feedback. The primary aims are to assess (1) change in employee work performance from pre- to postelliptical installation via employee and supervisor ratings and (2) effects of gift card type and schedule on quantity of objectively measured desk pedaling completed.

RESULTS

Data collection is ongoing. We expect to complete main outcome analyses in 2020.

CONCLUSIONS

This trial represents one of the earliest attempts to assess the effects of desk pedaling and pedaling-incentive types in real-world offices. It could help bridge the research-to-practice gap by providing evidence on whether desk pedaling can be sustained without compromising work performance.

摘要

背景

能够提供身体活动机会且无需额外花费时间进行活动的工作场所，有助于应对肥胖流行问题。台式椭圆机有助于营造支持身体活动的工作场所环境；然而，员工在办公的同时蹬踩椭圆机的可行性尚未得到充分评估。

目的

我们旨在介绍一项正在进行的针对超重和肥胖员工的随机试验的基本原理和方法，该试验将评估：（1）蹬踩紧凑型台式椭圆机对工作绩效的影响；（2）不同激励类型和时间表对台式椭圆机蹬踩量的影响。

方法

超重和肥胖的医疗中心员工将以二人组形式被招募，参与一项2（礼品卡类型：更健康食品与亚马逊礼品卡）×3（礼品卡时间表：根据个人蹬踩量立即给予激励；根据二人组的联合蹬踩量部分给予立即激励；延迟给予非条件蹬踩激励）的组内聚类随机因子试验。所有参与者将获得一台支持蓝牙的台式椭圆机，为期4周，并可使用一款提供实时蹬踩反馈的移动应用程序。主要目的是评估：（1）通过员工和主管评分，椭圆机安装前后员工工作绩效的变化；（2）礼品卡类型和时间表对客观测量的台式椭圆机蹬踩完成量的影响。
