新规则下中日单杠项目动作编排特征及竞技实力分析

Analysis of the Characteristics of Movement Choreography and Competitive Strength of the bar Events in China and Japan under the new rules

运用文献资料法、录像观察法和数理统计法等研究方法对新规则下中日体操锦标赛单杠决赛优秀运动员动作编排和竞技实力进行分析,探索单杠项目的竞争格局与发展趋势,为我国运动员提升单杠项目整体实力提供参考。结果显示:(1)中日动作编排有所不同。日本优秀运动员多以中穿转体动作开场,随后是高难飞行动作及其有效连接,后面为扣扭及掏杠类动作为主。我国同样多以中穿转体动作开场,后面为单个飞行动作提升难度,并以简单的转体类或掏杠类进行过渡,下法上则均以后直两周转体720°为主。(2)我国在整体难度上弱于日本,完成情况则优于日本。(3)我国有效连接少于日本,而在失误率上日本则居高不下。(4)在新规则实施的开局之年,运动员D分相对排名与最后名次呈正相关(P<0.05)。

Using the research methods of literature,video observation and mathematical statistics,this paper analyzes the movement arrangement and competitive strength of the outstanding athletes in the horizontal bar finals of the Sino Japanese gymnastics championship under the new rules,explores the competition pattern and development trend of the horizontal bar,and provides a reference for Chinese athletes to improve the overall strength of the horizontal bar.The results showed that:1) Chinese and Japanese movements were arranged differently.Most of the outstanding Japanese athletes start with the mid piercing and turning movement,followed by the difficult flight movement and its effective connection,followed by the button twisting and bar pulling movements.In China,most of the movements start with the mid penetration swivel movement,followed by a single flight movement to improve the difficulty,and a simple swivel or pull bar type transition is used.The lower method is mainly two straight turns 720 ° later.2) China is weaker than Japan in overall difficulty,and its completion is better than Japan.3) China has fewer effective connections than Japan,while Japan has a high error rate.4) In the first year of the implementation of the new rules,the relative ranking of D points of athletes was positively correlated with the final ranking(P<0.05).
