This study uses the PCA - CA comprehensive evaluation training model to provide 8-week training guidance to 40 college table tennis players, and uses expert interviews, questionnaires and other methods to evaluate the rationality of the "new four-segment indicators" for athlete statistics. The evaluation aims to provide a richer theoretical reference basis for future table tennis training in colleges and universities. The results show that athletes and coaches have higher cognitive performance of PCA - CA method in practical training, and in the comparison of pre- and post-experiment tests, PCA - CA method can improve the competitive level of athletes. It was concluded that the PCA - CA method is more suitable for coaching high-level table tennis players, but has poor on-site guidance for low-level athletes. It is recommended that this method be implemented in the national team or provincial table tennis team.
