Biomechanical and cellular factors affecting the speed and accuracy of tennis serve

This study discusses the biomechanical and cellular factors that affect the speed and accuracy of tennis service. By combining biomechanical characteristics (such as power chain, hitting point control, ground reaction, etc.) with cellular factors (such as muscle fiber type, energy metabolism efficiency, neuromuscular coordination ability, etc.), this paper analyzes the key mechanism of improving serve performance. The results show that the collaborative optimization of biomechanics and cellular factors has a significant effect on improving the service speed and accuracy. The research adopts measured data, literature review, and motion sensor data and draws the conclusion that high-level athletes are significantly better than ordinary athletes in various indexes, which provides scientific guidance for tennis training.
