A Multidimensional Talent Identification Program Model for School-Based Volleyball within the Long-Term Athlete Development Framework

Abstract

The ultimate achievement in elite volleyball demands a long-term, systematic development process spanning 6 to 11 years, necessitating effective Talent Identification (TI) programs initiated early in the educational pipeline. This study aims to formulate and validate a Multidimensional Volleyball TI model structured across three educational phases (Elementary, Junior High, and Senior High School), strictly integrated within the Long-Term Athlete Development (LTAD) framework. The proposed model adopts a phased approach: Pre-Screening (SD/Fundamental), critical Selection and Profiling (SMP/Training to Train), and Confirmation and Specialized Training (SMA/Training to Compete). The core methodology involves psychometrically validated, multi-dimensional testing protocols prioritizing non-negotiable biological factors, namely Anthropometry (e.g., body height and segment length) and Explosive Power (Vertical Jump). Data analysis utilizes descriptive statistics and a weighted scoring system to ensure objectivity. The results indicate that the SMP phase acts as the critical filter, where anthropometric criteria and explosive power are the strongest predictors (e.g., selected athletes demonstrate significantly higher height, 1.72 ± 0.06 m, p < 0.001), thus optimizing resource allocation for long-term specialization.2 Furthermore, the model serves as a diagnostic tool, identifying specific performance gaps (up to 70% of junior athletes show suboptimal fitness profiles) to inform individualized, targeted training interventions. The implementation of this scientifically validated, standardized model, primarily driven by Physical Education teachers, is crucial for strengthening the national athlete supply chain and maximizing the efficiency of long-term athlete development.
