Coordinated defensive tactics are an essential component of modern basketball, significantly influencing the ability to prevent opponents from scoring, maintain defensive stability, and enhance overall competitive performance. For male basketball players at Thuyloi University, the development of coordinated defensive ability requires a systematic and scientifically designed training program that is appropriate to their technical characteristics and competitive demands. Therefore, this study aimed to select and evaluate the effectiveness of coordinated defensive drills in improving the competitive performance of male basketball players of Thuyloi University.
The study employed a combination of research methods, including document analysis and synthesis, expert interviews, pedagogical observation, pedagogical experiment, and mathematical statistics. Thirty experts, lecturers, and basketball coaches participated in the interview process to determine the necessity and suitability of the proposed drills. Based on the interview results, eight coordinated defensive drills with an agreement rate of 85% or higher were selected for experimental application. The pedagogical experiment was conducted over six months, with a training frequency of three sessions per week, each lasting 45–50 minutes.
The results showed that after four months of training, the experimental group achieved a coordinated defensive success rate of 64.0%, significantly higher than that of the control group (47.1%) (t = 2.045; p < 0.05). After six months, the success rate of the experimental group increased to 69.7%, compared with 51.9% in the control group (t = 2.343; p < 0.05).
The findings confirm that the selected coordinated defensive drills were effective in improving defensive tactical performance and competitive effectiveness among male basketball players of Thuyloi University. These drills can be applied in basketball training programs and university sports teams to enhance competitive performance.
