Evolution of technical, physical, and defensive match performance parameters for central defenders in the German Bundesliga

This study examined the match performance evolution of central defenders in the German Bundesliga through a 10-year comparison between the 2014/2015 and 2023/2024 seasons. Match data for 105 players were obtained from the official league database, comprising technical, physical, and defensive parameters. The findings obtained from independent t-tests identified seasonal differences, suggesting a growing role in possession and build-up play, as well as a shift toward greater locomotor volume with fewer high-intensity efforts. A cleaner and more controlled defensive behavior was also observed. Overall, Bundesliga central defenders have apparently become more involved in the game from a technical and tactical perspective, while maintaining their efficiency in defense. This study underlines the improvement of technical proficiency and decision-making in defensive roles, which potentially highlight the importance of ball-related skills and match endurance in training design.
