|Objective：To explore the correlation between the core stability of volleyball players and the height characteristics of sudden stop jump. Methods：
Twenty first-level players of the professional volleyball team were selected to collect the dynamic and kinematic data of the subjects in the process of abrupt stop?
ping and jumping using a three-dimensional force table，a high-speed camera and a motion analysis system. The data of the subjects were collected by seven
core stability tests，including side plank support，side solid ball throwing，sit-up，trunk flexion and extension，superior side single leg standing，superior side sin?
gle leg long jump and trunk extensor endurance. Results：The higher the plantar pressure was，the higher the takeoff height. When the knee Angle of the athlete
was between 105 and 115 degrees，the height of the jump was the maximum. The main effects of single leg long jump，trunk flexion and extension and side throw?
ing solid ball on the dominant side were all significant，while no significant effects were shown in other core stability tests. Moreover，all three core stability tests
had a significant positive linear correlation with the height of sudden stop jump. Conclusions and Suggestions：The characteristics of plantar pressure can make
the height of jerky jump change correspondingly. The knee Angle affects the height of the jerk-stop jump of volleyball players. It is suggested to carry out special
training for the jerk-stop Angle during training，and the knee Angle range from 105 to 115 degrees is used during training. The superior side single leg long
jump，trunk flexion and extension and side throwing solid ball are the effective indicators to predict and improve the height of the sudden stop jump. It is suggest?
ed to adopt and strengthen these three core stability exercises in training，and take the maximum test distance as the training goal.
