Acceptability of Semi-recumbent Pedal Desk
Conditions
Brief summary
The purpose of this study is to assess full-time workers'impressions and acceptability of a prototype pedal desk. The pedal-desk is a semi-recumbent (upright) portable pedal mechanism that allows workers to complete tasks in a traditional seated position.
Detailed description
Researchers in recent years have begun to consider how modern occupational practices and environments could be enriched to facilitate increased energy expenditure by replacing sedentary behaviors with opportunities for non-exercise physical activity without competing with time committed to work tasks. The investigators have developed a pedal desk: a semi-recumbent (upright) portable pedal mechanism with a maneuverable and adaptable desktop. While utilizing the pedal desk, workers are able to complete their tasks in a more traditional seated position. Determining workers' acceptability is a key initial step in translating this sedentary behavior countermeasure to real workplace settings. In addition to having their height, weight, body fat percentage, and bioelectrical impedance measured, eligible participants will be asked to complete three tasks while simultaneously pedaling at a sustainable and self-selected pace. The three tasks are: 1) compose and send an email; 2) search a topic on the internet, and 3) complete an on-line questionnaire. The questionnaire that participants will complete was developed specifically for this study, utilizes Likert scales, and is based on the Theory of Planned Behavior. Constructs tested focus on perceptions of using the pedal desk at work and include: behavioral beliefs, normative beliefs, control beliefs, intention, self-efficacy, and an open-ended question soliciting general impressions concerning using the pedal desk at work.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pedal Desk Trial Questionnaire | Visit 1 | Full-time sedentary workers 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. The Questionnaire assessed subjective opinions about exercise and use of the Pedal Desk. No subscale or total scores were generated, and there are no maximum or minimum values. Rather, the number and proportion of participants who rated strongly agree, etc. on each item was calculated. |

Recruitment details
Full time employees of Pennington Biomedical Research Center will be invited by email to participate in an on-line screening survey. The on-line survey will include a series of questions to determine eligibility.
Participants by arm
| Arm | Count |
|---|---|
| Pedal Desk Acceptability Orientation sessions will last approximately 30 minutes and will provide participants detailed information about the study, including the number and type of assessments, the length and nature of the pedal desk trial session, the time commitment required, and the potential risks and benefits of participation. Participants will be given a copy of the informed consent form to read and review. Interested participants will schedule their 30 minute trial visit.
At the trial visit, participants' questions will be answered and they will be asked to complete the informed consent form prior to beginning any study procedures. At this one and only visit height, weight, body fat percentage, and Bioelectrical Impedance Analysis will be measured. Participants will also be asked to complete 3 computer based tasks while using the pedal desk (1) search a topic on the internet; (2) compose and send an email, and (3) complete an on-line questionnaire while utilizing the pedal desk. | 44 |
