Estimation degree of changes influence in competition rules on the contests ratios of judo wrestlers of lightweight categories in Russia and Kyrgyzstan

Abstract

The article deals with the comparative contests ratios of judoists - men representing the Russian Federation and Kyrgyzstan at national and international competitions. The competition bouts of 146 athletes competing in weight categories up to 60 and 66 kg were analyzed for 2 time periods: from 2003 to 2009 and from 2010 to 2015. Moreover, the separation for periods is associated with the introduction of significant changes in the rules of judo competition aimed to encourage athletes to conduct a dynamic and attacking struggle. The purpose of the research was to reveal the fitness of the athletes to conduct an active attack on the modified rules of the competition. Besides, the results of the analysis conducted by the authors show that the judoists in the category up to 60 kg in the second time period is a significant increase in such competitive factors as the number of common technical (P <0.01) and successful (P <0.05) groundwork. It should also be noted the decrease in time intervals between attacking actions is an average of 16 seconds and a decrease in the number of lost technical actions of athletes in a wrestling (P <0.001). Meanwhile, the athletes competing in the category up to 66 kg showed a significant decrease in both the total (P <0.01) and the successful (P <0.001) number of technical actions in the wrestling. Some increase in the rates is fixed in the number of moves performed by wrestlers in the ground fighting but the data does not contain significant differences. In general, the experts believe that the majority of athletes of this weight category formed a defensive style of fighting which does not correspond to the views of experts and judges on the modern judo. The trainers and athletes should make certain adjustments to the tactics of constructing a competitive bout.
