【摘要】：国内外撑竿跳高项目一直被世人广泛接受的4H公式理论(即:H=H_1+(H_2+H_3)-H_4),已不满足于现代撑竿跳高技术理论的需求。本文增加H5视角,以世界高水平运动员的技术数据为实证参考,采用运动生物力学摄影测量等研究方法揭示各成绩构成分量的情况与影响因素。研究表明:1)撑竿跳高成绩构成分量H5的提出,解释了人体重心最高点不在横杆最上方时所造成的实际重心高度下降的情况。2)世界高水平男、女撑竿跳高运动员的腾越高度主要依赖于运动员的握竿高度,男子选手过杆技术优于女子选手。3)世界男、女选手的伸展偏离角度越小,人体腾起的高度(H2)就越高。4)世界高水平男、女选手的预设架距与身体重心最高点的平均距离差值呈现出绝大多数优秀选手的身体重心最高点未能在横杆正上方,且差值越大,身体重心下降的高度(H5)也就越大。
[Abstract]:The 4H formula theory, which has been widely accepted at home and abroad for pole vaulting, is not satisfied with the demand of modern pole-vaulting technology theory. This paper increases the H5 angle of view and takes the technical data of the world's high-level athletes as an empirical reference. Sports biomechanics photogrammetry was used to reveal the situation and influence factors of the components of each achievement. The research shows that the component H5 of pole vault score is proposed. Explaining the drop in the actual height of the center of gravity caused by the fact that the highest point of the body's center of gravity is not at the top of the crossbar. (2) the world's high level male and female pole vaulters depend mainly on the height of the pole holder. Male athletes outperform female contestants. 3) the world male, the smaller the stretching angle of female contestant, the higher the height of human body rising. 4) the world high level male. The difference between the average distance between the preset frame and the highest point of the body's center of gravity shows that the highest point of the body's center of gravity of most excellent athletes is not directly above the crossbar, and the greater the difference is, the greater the height of the body's center of gravity drops.
