Experts will assess the relevance, clarity, and clinical appropriateness of each item. Feedback from this round will identify items requiring modification or clarification.\n\nPhase 2 - Round 2 (Re-evaluation):\n\nThe second phase consists of a consecutive online survey round, in which experts will re-evaluate the revised algorithm components based on feedback from Round 1. Experts will have the opportunity to adjust their ratings. This phase aims to move items closer to consensus (≥70% agreement).\n\nPhase 3 - Optional Focus Group (if needed):\n\nIf consensus is not reached on specific items after Round 2, an online focus group will be conducted to discuss and resolve remaining disagreements. This discussion will help refine the algorithm and ensure agreement on all components.","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.
