Effectiveness of Taekwondo Fight Evaluation (TAFEVAL) application among taekwondo coaches

Introduction: This study develops and assesses an Android-based evaluation application for Kyurugi Taekwondo athlete performance. The demand for precise performance assessment necessitates digital tools to enhance evaluation accuracy. This application provides a structured, real-time system for coaches to monitor technical, physical, tactical, and psychological aspects. Method: This study employed a Design-Based Research (DBR) approach involving 55 purposively selected Taekwondo coaches from West Java. The research comprised five stages: 1) a literature review to identify gaps in kyurugi performance evaluation and relevant technologies; 2) prototype development using B4X software based on identified needs; 3) expert validation by a subject matter expert, an informatics expert, and a measurement expert; 4) small-scale field testing with 15 coaches to assess feasibility and usability; and 5) final product revision and broader effectiveness testing with 40 coaches. Data collection included validation checklists, usability surveys, interviews, and in-app analytics. Results: Findings show the application is highly effective for real-time evaluations, offering accessible performance data anytime. Usability assessments indicate it is user-friendly and practical for coaching. The structured framework enhances comprehensive athlete analysis. However, recommendations were made to refine the assessment of psychological aspects for a more holistic evaluation. Conclusion: This application is a valuable tool for Taekwondo coaches, enabling structured and well-documented performance assessment. Real-time feedback and systematic evaluation enhance training quality and athlete development. Future improvements should focus on refining psychological evaluations to better assess athlete readiness and mental resilience.
