灰色关联分析在运动员竞技能力诊断中的应用

APPLICATIONS OF GREY-CORRELATIVE ANALYSIS TO DIAGNOSING ATHLETES' COMPETITIVE ABILITY

运用“多级估量测试量表”,“竞技心理能力量表”和灰色关联分析数学方法,揭示了运动员的竞技能力水平与运动成绩变化的制约关系。研究表明,竞技能力具有鲜明的专项特点,竞技能力诸要素的影响力是以关联度的量值和关联序的位次表征的。通过实例运算,介绍了点关联度,斜关联度,点、斜关联度的量化方法。

Using scaling of multi-step estimation, scaling of competitive psychological capacity and mathematical method of grey-correlative analysis, the restricted relations of the level of athletes competitive ability to the variety of athletic performance were revealed. This research topic demonstrated that the compectitve ability has distinct specific-events features. The influence ability of its various factors was expressed by the precedence of the correlativity value and correlative ordination. By calculating for a example, a quantifying method of point correlativity, oblique correlativity and point-oblique correlativity was given.
