摘 要:采用文献资料法、三维影像解析法和数理统计法等方法,对国家健将级和国家二级两种水平男子跳高运动员的技术数据进行分析。研究发现:高水平运动员起跳腿空间夹角明显大于二级运动员,不同水平运动员起跳腿空间夹角的变化趋势相同,同试跳高度成正比;不同水平运动员成功跳次的起跳腿空间夹角均大于失败跳次夹角,较大的起跳腿与横杆矢状面夹角对于二级运动员成功试跳有更大的作用;起跳点与横杆的距离、速度转化率、重心水平速度同起跳腿空间夹角有较大的相关性。Using the method of literature,three dimensional image analytic and mathematical statistics method etc,analyze the technique data of national level and national secondary level of male high jumper.Research finding: the take-off leg space angle of high level athletes obviously higher than the second-level athlete;the change tendency of different level in take-off leg space leg is the same and is proportinal to the height;the space angle of different level of high jumper in successful jump is bigger than failure;large sagittal angle of take-off leg and cross bar for second-level athlete successful attempt has a bigger role.The distance between take-off point and cross bar,the rate of speed conversion and the horizontal velocity of CG have great relevance with space angle of take-off leg.
