跳高项目属于体能主导类快速-力量项目,体能的发展水平直接决定着跳高运动员专项成绩的发展水平。文章对山西省青少年跳高运动员的体能特征进行了研究,结果表明:山西省青少年女子跳高运动员的下肢比例均值低于标准,但无显著差异;男子的身高、克托莱指数、下肢比例、踝围比跟腱和大小腿比例和女子其余四项均值都达到了选材的标准;山西省青少年跳高运动员的心功指数较差;山西省青少年跳高运动员的身体素质较为全面,但耐力素质和力量素质相对较差。如何把专项速度和专项力量科学的结合起来成为青少年跳高运动员的最重要的问题,也是提高专项成绩最有效的途径。 High jump project belongs to the body-led rapid class - the strength of the project, the level of development of physical fitness directly determines the level of development of high jumpers special results. The article studied the physical characteristics of Shanxi young high jumpers. The results showed that the average lower limb proportion of Shanxi young jumpers was lower than the standard, but there was no significant difference. The height, Ketuo index, lower limb proportion, The ratio of Achilles tendon to the size of the leg and the remaining four of the women reached the standard of selection; Shanxi youth jumpers had poor heart function index; Shanxi jumpers’ physical fitness was more comprehensive, but the endurance quality and strength quality were relatively Poor. How to combine the special speed with the special strength science to become the most important problem of the young high jump athlete is also the most effective way to improve the special achievement.
