Sports competition data analysis and strategy optimization using K-means clustering algorithm

Abstract

Sports competition data analysis and strategy optimization are important ways to enhance athlete competitiveness and team collaboration. The current competition analysis and strategy formulation have strong subjectivity, making it difficult to deeply understand the performance characteristics and patterns of athletes and teams. Traditional analysis methods cannot accurately identify the performance differences of different athletes, and there are limitations in their feature recognition and classification. In order to enhance the scientificity of strategy formulation and improve the performance of athletes in competitions, this article combined the K-means clustering algorithm and focused on basketball sports to conduct an in-depth analysis of sports competition data analysis and strategy optimization. Firstly, the competition data was collected and preprocessed. Then, feature selection was carried out from three dimensions: competition results, player performance, and team characteristics. Finally, the K-means clustering algorithm was used to perform hierarchical clustering on the original data through a hierarchical method. To verify its effectiveness, this article conducted practical analysis on the data of nearly 5 basketball competitions in 10 university basketball leagues in a certain province and optimized strategies based on cluster analysis. The results showed that in terms of player performance, compared to before optimization, the average number of rebounds, assists, and steals of team players optimized based on algorithm strategy increased by about 38.9%, 25.0%, and 63.2%, respectively. The conclusion indicates that the application of K-means clustering algorithm in sports competition data analysis and strategy optimization can help improve the competitive level of athletes and enhance their performance.
