三级跳远不同技术类型对成绩影响的研究

以50年代至今具有世界水平的三级跳远选手52组测试成绩为依据,根据1990年美国生物力学专家詹姆斯·沦博士依据三跳百分比划分三级跳远的三种模式,将52组测试成绩分成高跳型、平跳型、跳跃型三个水平组,运用方差分析方法,揭示三级跳远不同技术类型对成绩的影响。运用R型因子分析方法,探讨影响三级跳远成绩的相关因素,并揭示其内在规律,按主成分a_(ij)计算“权”确定三级跳远技术的三跳比例,为科学训练、技术诊断提供可靠依据。

A Study on the Scores Resulted from Different Training Strategies for Triple Jump

Based on the results made by 52 athletes of world-rank triple jump ranging from the end of 1950s to the present, and the three modes prescribed by the American biophysicist, Dr. James Leon in 1990, 52 groups of performances test are categorize into three different lever groups of doing hop, step and jump. The effect of different technical types of triple jump on performances is showed by applying with difference analysis method. Correlation factors affected by performances are discussed and inherent law of triple jump is opened out by statistical analysis (ANOVA) method and R-factor analysis method. In the mean while, a quantitative study has been utilized to determine proportions of "aij" value in doing hop, step and jump, which is of some significance for scientific training and technical diagnosis.
