Biomechanical Study on Take-Off Technique of Junior Male Long Jumpers

The take-off is the most difficult key technique stage of long jump. The related specifications of take-off directly affect long jumper performance. In this paper, biomechanics study method was used to analyse the factors of take-off such as the last two steps step length and pace, the landing angle, the pedal angle, the take-off sector-shaped angle, the jumping initial velocity and the jumping angle, etc, and the main influencing factors of take-off were decided, to seize these factors in the training will contribute to long jump level improvement.
