新周期男子单杠成套动作的“D”分价值与编排特征研究

运用录像观察法、数理统计法等对参加第42届世锦赛男子单杠决赛的8名运动员成套动作的"D"分及构成情况、动作的编排情况进行了对比分析。研究表明:新周期男子单杠的"D"分呈不断增长的趋势,在本周期内的余下体操大赛中,单杠决赛的"D"分均值将保持在7分以上;成套难度动作价值对单杠"D"分的增长贡献较小,而成套连接价值的增加对其贡献最大。新周期单杠项目的编排亦具有如下特征:1)单杠项目的杠上动作难度保持在D组水平,不断发展杠上动作与飞行动作间的连接成为趋势;2)单杠项目的飞行动作中,D、E组难度价值的动作将迅速发展,而且在成套单杠动作编排中,飞行动作的出现将伴随连接价值的产生,其数量也将向4个发展;3)单杠项目进入了高难连接的发展阶段,并在连接类型及动作上呈多样化发展趋势;4)单杠下法动作依旧以直体后空翻2周720°旋下为主流,对下法动作的编排将以稳定性为原则。

Score D and features of arrangement of men' s horizontal bar routine in new cycle

By means of video analysis and mathematical statistics,the comparative analysis is carried out on the Score D and its consistence and movement arrangement of 8 gymnasts’ routine in men’s horizontal bar final of the 42th World Gymnastic Championships.Research shows that: in the new cycle,the Score D of men’s horizontal bar is increasingly growing,the horizontal bar final of the Score D in mean remain more than 7 points in the rest of gymnastics competition this cycle;The Score D of growth is negatively related to difficulty value,but is directly connected with the increase of the connection points.The horizontal bar’s arrangement also has the following characteristics during the new cycle: 1)the difficulty on bar will remain at the level of group D,and it has continuously devel-oping tendency that makes the connection on bar and flight element;2) D,E group developed rapidly in the flight elements,it can be accompanied by the emergence of connected value and the amount of development will also be 4;3)Horizontal bar has been into the development stage of a highly-difficult connection,and its connection type and element are on diversified development trends;4) the dismount remains "Watanabe" for the mainstream and the arrangement of the dismount should stick to the principle of stability.
