排球防守技术中的非正规动作是指综合多种正规动作特点的边缘型技术。其显著特征是动作缺乏规范化,但起球率较高,符合实战的需要。采用文献资料法、访谈法、现场统计法、比较分析法对我国青年男排运用防守技术中非正规动作进行研究。结果显示,排球防守技术中非正规动作与正规动作相互联系、相辅相成;我国青年男排临场运用防守技术中非正规动作的时机主要出现在处理各种困难球,这不仅丰富了防守技术动作,而且显示出一定的实用价值,并可以按动作方法对其进行分类;我国青年男排临场运用防守技术中非正规动作所占的比例已达到19.5%～26.2%,这表明防守技术中非正规动作已成为运动员临场所需要运用的一种技术动作,并且教练员单纯强调防守时正规动作的运用并非完全符合现阶段实战的需要;我国青年男排中,江苏、辽宁和山东3支球队运用防守技术中非正规动作的起球率较高,而浙江等5支球队与上述3队存在着一定的差距,这主要与教练员未安排该方面的训练,运动员未能熟练掌握与运用防守技术中的非正规动作有关。
Irregular movements in volleyball defensive techniques are edge-based techniques that combine the characteristics of a variety of normal movements. Its notable feature is the lack of standardization of action, but a higher pilling rate, in line with actual needs. By using the methods of literature review, interview, on-the-spot statistics and comparative analysis, this paper studies the non-formal movements of Chinese youth men’s volleyball team using defensive techniques. The results show that the non-formal and informal motions of volleyball defense are interrelated and complement each other. The timing of the non-formal action of defensive technique on the spot in Chinese youth volleyball mainly appears in dealing with various difficult balls, which not only enriches the defensive technique, Showing a certain practical value, and can be classified according to the action method; the proportion of non-formal action in China’s young men’s volleyball team on-the-spot use of defensive technology has reached 19.5% ~ 26.2%, indicating that the defensive technique has been informal Become a kind of technical action that the athlete needs to apply to the spot, and the trainer simply emphasizes the use of the regular action when defensive is not in full compliance with the actual needs of the current stage; China’s youth volleyball, Jiangsu, Liaoning and Shandong three teams using defensive techniques The regular pilling rate in Central Africa is relatively high, while there are some gaps between the five teams in Zhejiang and the above three teams, mainly because the coaches did not arrange training in this area and the athletes did not master and use defensive techniques Related to non-formal actions.
