Introduction. Changes in the rules of competitions and the rules of fights of Greco-Roman style wrestlers by the international federation UWW after the 2012 Olympics have affected the main components of the training structure of highly qualified wrestlers [1, 2]. In 2013, a number of changes were introduced into the rules of holding competitions in Greco-Roman wrestling: instead of 3 periods of wrestling for 2 minutes - 2 periods of 3 minutes, the obligatory staging of wrestlers in the stalls and determining the winner by the number of periods won was canceled [1].
Objective: to determine the dynamics of sports and technical indicators in connection with a change in the rules of the competition.
Results and discussion. Previewed, analyzed, preliminary, semi-final, final and fights for 3rd place in all weight categories of Greco-Roman style wrestlers at the 2016 Olympic Games in Rio de Janeiro and 2012 in London. Unlike the 2012 Olympics, where there were no such victories, the number of net carcass victories in 2016 is 8.8%. The situation is similar with the number of battles won by technical superiority: in London - no, in Rio de Janeiro - 7 times (2.3% of the total number of victories). The largest number of fights won at both Olympiads are points wins. In London - all meetings ended with the advantage of one of the rivals in terms of points; in 2016, 78.9% of fights ended with this result. At the same time, the effectiveness of technical actions in London was 1.34 ± 0.04 points, in Rio-De-Janeiro - 1.76 ± 0.07. The interval of a successful attack in London was 94 ± 13s, in Rio - 99 ± 19s. The average time of competitive fights has also increased from 4 minutes 24 ± 22s in 2012 to 5 minutes 29 ± 33s in Rio. The average number of technical actions for a fight in Rio was 3.31 ± 0.57, which is 0.51 more than in London. The average number of points scored for a duel at the London Olympics (3.68 ± 0.20) is 2.17 points behind that in Rio.
Conclusion. A change in the rules in the Greco-Roman wrestling for the 2012-2016 Olympic cycle had a positive impact on the dynamics of sports and technical indicators and the entertainment of wrestling fights. The nature of the victories has changed: while the London Olympics were dominated by “boring” victories in points, then in Rio de Janeiro they were spectacular: on the carcass and beyond obvious superiority. Significantly increased the number of points won for the meeting, technical actions and their effectiveness. A change in the formula of fights led to an increase in the average duration of the bout and the duration of an effective attack.
