Analysis of Technical Characteristics of Ren Mengqian, an Excellent Pole Vaulter

Abstract

To advance the development of Chinese women's pole vaulting technique, three-dimensional photogrammetry and video analysis methods were utilized to conduct kinematic analysis on the technique employed by Ren Mengqian, an outstanding female pole vaulter in China, during the 2019 National Indoor Track and Field Championships finals from an energy transfer perspective. The findings indicate that during the energy acquisition stage, Ren Mengqian executed a reasonable jumping action with appropriate jumping angle and timing that met technical requirements. However, during the energy storage stage, her bow rod had suboptimal effects in her fourth trial jump while insufficient bending of the rod occurred in her fifth trial jump which affected pole energy storage. In terms of energy release stage, Ren Mengqian maximized elastic potential energy through stretching but required acceleration for maximum vertical speed.
