Precise measurements of maximum speed and position of maximum speed during sprinting have essential inferences for planning and improving the individual performance of long jump athletes. Coaching in the approach-run phase is somewhat difficult because the athlete’s movement is very fast. Therefore, the aim of this study was to evaluate the validity of the knowledge transferring of Knowledge-Based System (KBS) for training long jumpers in the approach-run phase which was compared with the Tracker video analysis software. Twelve healthy adults (Average age=27.58 years old, SD=9.67, Variance=93.53) were randomly selected for data collecting. The participants performed walking, jogging, running and fast running trials and static starts at about 20-25 m. distance from a take-off board. Descriptive statistics, Cross-tabulation and Spearman's Rho were employed for statistical analysis. The results showed strong significant relationship between both systems at Spearman's Rho Correlation = 0.916, p-value <0.01. The results also indicated that the proposed KBS could be used to accurately evaluate transferring of knowledge in the approach-run phase.
