Abstract: The new generation of male long jumpers in our country is currently at a critical stage in enhancing their competitive abilities. To help athletes break through the performance plateau, this study employs a combined approach of systematic bibliometric analysis and cross-sectional data analyses to identify the characteristics of world-class athletes capable of competing for titles in international competitions. It then screens for core biomechanical covariates that influence athletic performance and, using MATLAB mathematical software, establishes a regression equation for the winning factors highly correlated with long jump performance. The results indicate that international athletes have significantly better BMI and height parameters compared to domestic athletes. There is a significant positive correlation between 100-meter performance and long jump results; The final 10-meter sprint speed during the approach run also shows a high correlation with performance; The vertical velocity at takeoff also demonstrates a high correlation with performance. In terms of physical fitness, it is primarily characterized by outstanding short-distance acceleration and lower limb stiffness adaptation capacity. In terms of motor skills, this manifests as the ability to optimize the timing structure of take-off and to regulate as well as optimally allocate vertical and horizontal velocity components.
