| Abstract: | In this paper, an equation of biomechanics about the best take-off angle of long jump is derived. And the paper analyzes some factors of long jump result and the relations between the utilizing rate of running speed, the perpendicular speed and the best take-off angle. Consulting the technical data of long jump result of many excellent long jumpers, the perpendicular speed is the most important factor of long jump is analyzed in depth. |
