SELECTION OF LONG JUMP ATHLETES PARTICIPATING IN GENERAL SECONDARY SCHOOL SPORTS SECTIONS BASED ON AGE-SPECIFIC PHYSICAL DEVELOPMENT

Abstract

This article investigates the scientific principles underpinning the selection of young long jumpers, with particular emphasis on chronological and biological age, physical development, motor performance, and the Relative Age Effect (RAE). Specific attention is devoted to speed, explosive strength, jumping capacity, coordination, and anthropometric characteristics as key determinants of athletic potential. The study highlights that athletes within the same chronological age category may exhibit substantial differences in biological maturation and physical development, potentially influencing selection decisions and competitive outcomes. Furthermore, the RAE may confer temporary developmental and performance advantages on athletes born earlier within a given age-group cohort, thereby affecting the fairness and accuracy of talent identification.Accordingly, an effective and scientifically grounded selection framework should integrate age-related developmental characteristics, physical and anthropometric indicators, motor abilities, and individual performance trajectories rather than relying solely on current competitive results. The findings underscore the importance of early, systematic, and evidence-based talent identification and provide a methodological basis for enhancing the objectivity, inclusiveness, and long-term effectiveness of athlete selection within school-based sports programmes.
