　　Abstract: With the gradual physical training systems and scientific theories, core strength training more and more attention by many coaches. At present, the application of core strength training in Taekwondo significance only stays at the theoretical level is not related to the experimental study. This study used experimental method and mathematical statistics method, the Shenyang Sport University 16 Taekwondo two stage athlete of core strength training experimental study. The results showed that their choices of 8 items special physical quality index, through the core strength training have improved. Through the matching sample t-test, the seven indicators of high horizontal kick target, fast playing sandbags, continuous quickly filed a knee, the continuous single leg rapid horizontal kick target and continuous single leg foot split target special physical quality indexes are highly significant difference; The index of bilateral back spinning kick despite have a raise, but the difference was not significant. Hope this research to for the future in the core system introduces taekwondo strength training is a reference.

　　1 INTRODUCTION
　　Core strength is the core muscle to classify the strength from the aspect of anatomy, which is the strength to maintain the gravity, control body’s balance and transfer the strength required during the motion, generated by shrinkage under the control of all muscles and ligaments. Core strength training is comprehensive, systematic and scientific strength training for all muscles. It is a kind of modern physical training, to improve athlete’s core strength through varied training instruments and methods, which can be applied to many items1-3.
　　Taekwondo is a skill-ruling antagonistic group of combat, which requires comprehensive physical qualities. Strength, velocity, smart, and patience are leading ones. Velocity and explosive force are main factors. Athletes have to change their velocities and directions according to current situations. They have to change bodies’ gestures to keep their balance. Such training can firm spine and make pelvis to keep the correct motion, to improve the ability of controlling and enhance the energetic exports to improve the effects4-6.
　　2 RESEARCH OBJECT AND METHOD
　　2.1 RESEARCH OBJECT
　　This paper selects 16 male students as samplings, majoring in taekwondo, in grade of 2008 and 2009 in Shenyang Institute of Physical Education, are all of them are Grade-2 athletes. It focuses on the effect of core strength training on athlete’s special physical qualities. There are eight people in the reference group, and others are in experiment group.
