Study summary

The purpose of this study is to: (a) evaluate if a desk-based elliptical device can help employees to increase their daily physical activity without compromising work productivity; and (b) evaluate the effects of different types of incentives for pedaling the desk-based elliptical device on employees' pedaling quantity over a one-month intervention period. The study will involve placing a compact elliptical device (provided at no cost by the research team) under employees' desk at Penn State Hershey Medical Center/College of Medicine. Data evaluating the effects of the elliptical device on work productivity will be obtained from both employees and the employees' supervisors.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Interventions

  • BehavioralDesk-based pedaling device and pedaling incentives provided

    Varying types of incentives, equivalent in monetary value, will be randomly assigned across the 6 arms to promote regular desk-based pedaling. A free desk-based pedaling device will be provided. Effects on amount of desk-based pedaling and work productivity will be evaluated.

What researchers measure

Primary outcomes

  1. Change in Worker Productivity

    Self-report assessments of worker productivity. The assessments will ask about work productivity in the prior 4-week period.

    Time frame: Baseline (1 month period prior to program start) and post-program (immediately after program ends)

  2. Elliptical Device Pedaling Quantity

    Objectively-measured pedaling quantity from elliptical device

    Time frame: 1 month (4 weeks) during pedaling program

Secondary outcomes

  1. User satisfaction, process evaluations

    Satisfaction with intervention condition

    Time frame: Post-program (immediately after program ends)

  2. General (non-desk pedaling) physical activity

    Self-reported physical activity

    Time frame: Baseline (1 month period prior to program start) and post-program (immediately after program ends)

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Oct 2017 to primary completion in Jun 2019, 19 months.

Of 5,147 non-industry interventional studies with no phase under Motor Activity, half reached primary completion within 17 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 36. This study's 19 months is above that.

Counting every sponsor, half of 5,207 studies reached it within 17 months; a quarter within 7 and three quarters within 36.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 19, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
