What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
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 Results may not be published yet.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

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.

Summary

This study asks 9 international experts to review a new algorithm designed to screen health risks and create personalized exercise plans. Over two rounds of online questionnaires, they will rate how clear and useful each part of the algorithm is. If successful, this tool could help people exercise more safely on their own, but it is still in the early idea stage.

What this could mean

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

What this could lead to
If validated, this algorithm could help people exercise more safely and effectively on their own, potentially improving health at a population level.
What could go wrong
This is a very small study (9 experts) that only gathers opinions, not real-world results. The algorithm may not work as well in practice or for diverse populations.

Who can take part

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

Who is studied

The study population will consist of international experts in the field of Physical Activity and Exercise. Participants will be identified based on their recognized scientific or professional experience and possession of a relevant doctoral degree. Recruitment will be primarily via institutional email invitations, supplemented by personal contacts when needed. Eligible experts will voluntarily participate in two rounds of an online modified Delphi questionnaire and, if required, an online focus group to resolve any remaining disagreements. The targeted panel size is 9 - 18 experts to ensure representativeness and methodological robustness.
