On the basis of analytical hierarchy process (AHP), this paper makes an analysis of badminton from four aspects: physical quality, spirit of cooperation, reaction quality and innovation ability. This paper concludes that humanities training accounts for 44.7% whereas physical training accounts for 55.3% in badminton, which demonstrates that badminton is not just a sport of challenging physical limits, but the one which calls for technics, skills and so forth. After a geometric model is established, this paper discusses that when an athlete spikes, he or she should try to keep the arms straight in front and vertical to the striking point. The higher he or she jumps, the more likely that ball can pass over the net. And the height of the striking point determines the trajectory and landing point of the ball. Thus, according to different vertical heights of the striking point, this paper classifies the height into six categories: 1.6, 1.7, 1.8, 1.9, 2.0, and 2.1. The angles that athletes smash the ball also differ; therefore this paper makes an analysis of spiking from the perspective of striking angle. Afterwards, on the basis of the spiking angle, the position where the ball is hit obliquely into the opponent’s court is also studied
