Expert Validation of an Autonomous Personalized Physical Activity Algorithm

Recruiting now

Conditions studied: Experts in Physical Activity Prescription and Risk Health Screening

In brief

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.
