What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only This study
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

Researchers are checking whether a step test on a 25 cm board can measure cardiorespiratory fitness and breathing thresholds as well as a standard lab cycling test. Thirty healthy adults complete one cycling test and two step tests, each with breath and heart rate monitoring. The study compares oxygen use at key thresholds and checks whether repeated step tests give consistent results.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
an incremental step test using a 25 cm step platform
What this could lead to
If it works, fitness and breathing thresholds could be measured with a step board instead of expensive lab equipment, making testing easier to do in gyms or clinics.
What could go wrong
This is a small validation study in 30 healthy adults, so the step test may not match the lab test closely enough or may not work for people with health conditions.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 30 people

The number the study aims to enrol. It can still change while the study runs.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Healthy adults aged 18 to 55 years. 2. Body mass index between 18.5 and 29.9 kg/m². 3. Non-smoker. 4. No known cardiovascular, respiratory, metabolic, neurological, or musculoskeletal conditions that would contraindicate maximal exercise testing. 5. Able to provide written informed consent. 6. Willing and able to complete one Cardiopulmonary Exercise Test and two Incremental Step Test sessions. Exclusion Criteria: 1. Age younger than 18 years or older than 55 years. 2. Body mass index below 18.5 kg/m² or above 29.9 kg/m². 3. Current smoker or use of nicotine products. 4. Known cardiovascular, respiratory, metabolic, neurological, or musculoskeletal conditions that may affect exercise performance or make maximal exercise testing unsafe. 5. Any contraindication to maximal exercise testing according to established exercise testing guidelines. 6. Use of medications known to significantly affect cardiovascular, respiratory, or metabolic responses to exercise. 7. Current injury, illness, or infection that may limit participation in exercise testing. 8. Pregnancy. 9. Inability to provide informed consent. 10. Inability to complete study procedures or attend all required study visits. \-
