标题：The course of the backward attacks in judo, after the first change of the rules, based on The World Championship from 2009 and 2011 in over 100 kg category. A pilot study
摘要：The aim of this article was to verify if the course, dynamics and time-structure of the judo fight in light of backwards attacks were changed after the radical change of the rules. It was presented the pilotage analyse of the fights containing the backward attack - based on the video recording from the World Championships in Rotterdam in 2009 (before the change of the rules) and The World Championships in Paris in 2011 (after the change of the rules) only in heaviest category The total of 97 male fights in over 100 kg category were verified. The analysis of backward attacks conducted through the video recording of the fights from The World Championships in Rotterdam in 2009 (before the change of the rules) and The World Championships in Paris in 2011 after the first change of the rules showed identical frequency of backward attacks and identical number of fights terminated before the set time because of those attacks. However, the time structure of the fight showed the fight in a totally new picture. That, in turn, brings new challenges for the coaching staff and imposes the changes in defence tactics.
