HU Zhi-gang,DONG Shao-wei(Department of Physical Education,Harbin University of Science and Technology,Harbin150080,Heilongjiang China)  
At present,the hurdles which are knocked down in training or race have to been reset manually.Therefore,in order to save labor and time,the auto-resetting hurdle is being developed on the basis of physics,athletic mechanics and relative reliable designing-theories.Building block design has been adopted in the hurdle and magnetic force is applied to resist the outside force.The development and application of the auto-resetting hurdle will effectively solve the problems in hurdle race and thus meet the demand of the race and training of different events.
