Dynamics characteristics study of pole vault based on energy analysis

Author(s): Sheng Meng

Pole vault belongs to the more complex technique and more difficult sport in track and field events; it is jumpingmovement that carries vaulting pole devices. Many predecessors take athletes as research object too much in previous studies. But the movement as a whole is a system, and only study part of it has some limitations. So this article starts fromthe athlete’s gripping pole height, the run-up speed and deformation degree of the pole, carries through energy analysis on athletes and vaulting pole system, analyzes the dynamic characteristics of the athletes in the system through energy conversion law, aims at discriminate the pros and cons of present technological action, and provide a theoretical basis for technological improvements. The analysis results show that the athlete’s height, runup speed, gripping pole height, vacated height and material properties of the vaulting pole determines the results of the movement.
