Expert Validation of an Autonomous Personalized Physical Activity Algorithm

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.

Inclusion Criteria * 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. Exclusion Criteria * 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.
