Study aim. The specialists note that the latest changes in the rules of judo have a negative impact on the quality of competition between the athletes representing the Russian Federation and the CIS countries. In connection with this the goal of the research was to search for the objective and informative criteria for assessing the level of preparedness of the judoists in Russia and Kyrgyzstan for conducting competitive fights. Another purpose of the research was to analyze the readiness level of the elite judo athletes from Russia and Kyrgyzstan to conduct competitive attacking fight in conditions with the significant changes of the rules of judo competitions based on the selected criteria. Methods. The total number of the judoists – n = 176. The athletes competed in categories less than 60, 66, 73 and up to 81 kg. The time period for the research is 6 years (from 2010 to 2015). The level of the athletes’ readiness was determined by comparing the competitive coefficients (CC) of the judoists. The authors attribute to the significant CC of the number of won and lost technical actions, activity in a duel and time intervals between the attacking actions. CC values ​​were determined by the method of analyzing the competitive judo matches. For the analysis, the specialists were involved: the high-level coaches and international judges – n = 16. The number of the studied judo competition – 4032. Results. Comparative analysis of the CC showed that the athletes of all weight categories reliably (P <0.001) reduced the time interval between attacking actions in the matches. At the same time, the number and quality of Nage-waza technical actions of the athletes of the weight categories less than 60 and 66 kg were revealed. Data CC significantly (P <0.01) increased in judoka categories to 73 kg. Besides, the athletes less than 81 kg did not show significant changes in the Nage-waza quantity and quality factors. It should also be noted that the number of lost Nage-waza receptions of the athletes of categories less than 60 and 66 kg has been reduced. The authors suggested that the judoists of light weight categories formed a defensive style of conducting competitive matches on the whole. Moreover, this style is characterized by a reduction of the risk of attacking Nage-waza actions and an increase in the number of Ne-waza receptions. The most meet the requirements of the modern judo CC athletes less than 73 kg. Consequently, the judoists less than 81 kg according to the majority of the CC have not significantly improved the quality of the competition during the research. Conclusions. Furthermore, in view of the new rules of the IJF for conducting an active attack training of the judo wrestlers for competitive activities should be based on the CC athletes. CC wrestlers are determined by the method of the mathematical analysis of the competitive fights of the athletes for certain time periods. Increase and decrease of data CC is an informative indicator of the level of readiness of a judoka in a certain component of the competition. However, the analysis of the CC judoists of the combined teams of Russia and Kyrgyzstan showed that the athletes of weight categories less than 60, 66 and 81 kg formed a generally defensive style of fighting. Besides, this style is aimed at keeping the gained advantage through the false activity and increasing the technique of Ne-waza. The most adapted to the modern requirements of IJF were the athletes weighing up to 73 kg.

2010年至2015年俄罗斯和吉尔吉斯斯坦(少于60公斤,66公斤,73公斤和81公斤)的优秀柔道运动员的竞赛系数

学习目标。专家们指出,柔道规则的最新变化对代表俄罗斯联邦和独联体国家的运动员之间的比赛质量产生了负面影响。与此相关,研究的目的是寻找客观和有益的标准,以评估俄罗斯和吉尔吉斯斯坦的柔道主义者为进行竞争而准备的水平。该研究的另一个目的是分析俄罗斯和吉尔吉斯斯坦的优秀柔道运动员在根据所选标准对柔道比赛规则有重大改变的条件下进行竞技进攻比赛的准备水平。方法。柔道运动员的总数– n =176。这些运动员参加的类别少于60、66、73和不超过81公斤。研究时间为6年(从2010年到2015年)。运动员的准备水平是通过比较柔道运动员的竞争系数(CC)来确定的。作者将获胜和失败的技术动作,决斗中的活动以及攻击动作之间的时间间隔的有效CC归因于CC。CC值是由分析柔道竞争性比赛的方法确定的。为了进行分析,专家参与其中:高级教练和国际法官– n =16。研究的柔道比赛的数量–4032。结果。对CC的比较分析表明,所有体重类别的运动员都可靠地(P <0.001)缩短了比赛中进攻动作之间的时间间隔。同时,揭示了体重类别分别小于60和66公斤的运动员的Nage-waza技术动作的数量和质量。柔道类别的数据CC显着(P <0.01)增加到73 kg。此外,体重不足81公斤的运动员在Nage-waza数量和质量因子上没有显示出明显的变化。还应注意的是,少于60公斤和66公斤类别的运动员丢失的Nage-waza接待处的数量已减少。作者认为,轻量级的柔道主义者在整体上形成了进行比赛的防御风格。此外,这种风格的特征在于降低了攻击纳格-瓦扎行动的风险,并增加了新瓦扎接待的数量。重量小于73公斤的现代柔道CC运动员最能满足要求。所以,在研究过程中,根据CC多数国家的规定,低于100公斤的柔道运动员并未显着提高比赛质量。结论。此外,鉴于国际柔术联合会针对柔道摔跤选手进行主动进攻训练以进行竞技活动的新规则,应基于CC运动员。CC摔跤运动员是通过对特定时间段内运动员进行的比赛的数学分析方法确定的。数据CC的增加和减少是柔道运动员在比赛某些组成部分中的准备水平的有益指示。但是,对俄罗斯和吉尔吉斯斯坦联合小组的CC柔道主义者的分析表明,体重类别低于60、66和81公斤的运动员形成了一般的防守风格。除了,这种风格旨在通过虚假活动保持获得的优势,并提高Ne-waza的技术。最适合IJF现代要求的运动员是重达73公斤的运动员。
