Inclusion criteria

  • 18-65 years
  • Ability to type without looking at the keyboard
  • Native English speaker
  • Normal hearing
  • Spend 6 or more hours per day sitting
  • Less than 150 minutes of physical activity per week

Exclusion criteria

Exclusion Criteria:

  • Positive response on the Physical Activity Readiness Questionnaire indicating that low intensity pedaling could present safety risks
  • Pregnancy
  • less than 18 or greater than 35
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.

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 Aug 2016 to primary completion in Sep 2017, 13 months.

Of 3,680 non-industry interventional studies with no phase under Obesity, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 43. This study's 13 months is below that.

Counting every sponsor, half of 3,843 studies reached it within 22 months; a quarter within 10 and three quarters within 42.

How these figures are worked out, and which studies are left out of them.

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 Mar 21, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
