About this trial
This study aims to validate a personalized physical activity algorithm for risk screening and individualized exercise prescription using a modified online Delphi process. International experts in physical activity and exercise will evaluate the algorithm's components over two rounds of questionnaires, with consensus defined as ≥70% agreement. If needed, a focus group will resolve any remaining disagreements. Validation of this algorithm may support safer, more effective autonomous exercise, promoting adherence, improved health outcomes, and population-level benefits.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Experts in Physical Activity and Exercise with recognized scientific or professional experience and a relevant doctoral degree.
Availability to complete two rounds of the online modified Delphi questionnaire.
Willingness to participate in an online focus group if consensus is not reached.
Ability and willingness to provide informed consent.
Disqualifiers
Individuals unable to provide informed consent.
Individuals without access to a computer, smartphone, tablet, or other internet-enabled device necessary to complete the online survey.
Trial population
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.
