Gansu Province male outstandi ng amateur badmi nton players smash process lower squatting phase and landing buffer stage completed ti me difference larger, mainl y for on positive judgment to the ball position and landi ng buffer stage attitude stability of difference;3. Gansu Province male outstandi ng amateur badmi nton players backcourt forehand smash action difference between larger, individual athletes in the smash jump high enough hi gh, trunk agai nst the bow amplitude is small and the elastic potential energy reserv e is poor. Parts of the joint angle, the maxi mum speed difference caused by the moment, action is not enough coordination, coherence, the cumulative effect of the i mpact velocity, the i mpact velocity decreases;4. The best amateur athletes in Gansu provi nce smash instant ball point selection, at the moment of the ball racket smash speed transmission loss;5.

By using the gray correlation analysis method to study the effect of smash action of many factors, which smash strength, speed of swing, smash moment to shoot surface angle and the contact point selection factors is an i mportant factor which affects the backcourt forehand smash action.The research results show that the excellent amateur male athletes i n Gansu province started late, the special physical quality is poor. The athletes of the badminton backcourt forehand smash action is not standardized, not comprehensive enough to smash technical understanding. Through the analysis of the technical movement of the athletes, the targeted guidance, can effectively i mprove the level of athletes badmi nton.
