Badminton Skills Diagnostic Model (BSDM) Instrument Design: Based on Cybernetic Theory

Abstract

This research aims to observe the contribution of the cybernetic-based badminton skills diagnostic model (BSDM) instrument design formulation as an effective instrument for achieving good motion analysis. Technical and tactical actions are very decisive in competitive badminton players' terms. The use of cybernetic theory becomes the diagnosing basis and improving skills. Cybernetics regulates a goal-directed self-regulation system based on the stimulus process, and the response that occurs. This study uses the Research & Development method. This process is carried out in four distinct steps: first, review of the scientific literature; second, qualitative and quantitative assessments were carried out by 8 experts in the fields of motion theory, tests and measurements and badminton; third, content validity was estimated using the Aiken V Coefficient; Finally, the intra-observer reliability and inter-observer reliability were tested by two badminton-specific observers using the Kappa Cohen coefficient and the intraclass correlation coefficient. For practicality and effectiveness, testing was carried out on 95 badminton players. Footwork, Execution, Shuttlecock running, and Stroke are used as units of measure by observation instruments in badminton. The data analysis process uses SPSS 25 statistical software. Based on the results, an observation instrument designed to be valid, reliable, and effective to analyze the technical and tactical actions of badminton playing skills. It is possible to analyze players who are lower class and elite class. The result of the flagship project is to present the instrument design solution of cybernetic-based badminton skills diagnostic model (BSDM).
