Abstract
In the rapidly evolving landscape of sports performance management, the integration of Big Data analytics has become a game-changer. This paper established a sports performance management system on big data decision tree ID3 algorithm and analyzed the accuracy and time of the improved decision tree ID3 algorithm in sports performance management. The research results show that the data query and data display functions are widely used in the system, and the utilization rate of each function of big data in the system can be clearly seen. In the accuracy of sports performance management, the improved ID3 algorithm is obviously higher than the ID3 algorithm, and the accuracy is improved by 4.16%. In the average time of sports performance management, the improved ID3 algorithm takes less time than the ID3 algorithm, and the time is reduced by 31.50%. The big data technology used has greatly changed the performance information management system of colleges or sports events and provides a research reference for the management of sports performance.
