Research on the application and technical optimization of combining biomechanics and multi-ball training method in tennis teaching

With the growing popularity of tennis, improving players’ technical skills has become a key focus in tennis instruction. This study investigates the application of a multi-ball training method integrated with biomechanical principles in tennis teaching and its effect on technical optimization. A total of 40 university tennis enthusiasts participated in this research, divided into an experimental group (EG) and a control group (CG) using a double-blind randomized controlled trial. The experimental group used a data-driven intelligent training system that incorporated sports biomechanics analysis and provided real-time feedback, while the control group adhered to traditional teaching methods. The results showed that the experimental group significantly outperformed the control group in biomechanical parameters such as swing speed, shot accuracy, and body stability. Furthermore, the experimental group demonstrated improvements in cognitive neural response, sports anxiety, and achievement motivation. By combining biomechanics with the multi-ball training method, this approach optimizes technical performance, enhances motor control, and improves training efficiency. This study provides new scientific evidence and practical insights for tennis instruction.
