Abstract: A dialectic analysis is made of the impact of the approach speed upon the long jump performance, which reveals that the approach speed plays a positive role in enhancing long jump performance. The point lies in that it manifests a macro developmental trend and the statistical law. While in doing the job of increasing the approach speed, it is of vital importance to set up a strength reinforcement system and technique system compatible with the approach speed promotion process so as to build up a holistic technical system of spiral escalation that is based on the enhancement of the approach speed.
