Abstract:
In present day information sources it is possible to find only restricted kind of data concerning kinematic parameters of performing the most important and difficult phase of diving – water entry. There are publications of Gorokhovsky L.Z. [1], Raspopova E.A. [2] as well as the works of the authors of this article [3], dedicated to splash formation during sports diving fulfillment, however, they do not fully reflect all theory and practice issues of this kind of sport. The main papers of the foreign authors, who study water entry quality, are focused on hydrodynamics [4, 5, 6]. There appear the questions concerning the kinematics of athletes’ movements during the moment of diving. They provide the quality of water entry. Therefore, this article is devoted to analysis of kinematic parameters of the participants’ movements at the Olympic Games 2020 in diving from three-meter springboard. Material. The article describes kinematical analysis of the final phase of the dive fulfillment by the World’s strongest athletes on the basis of video material of the final competition of the Olympic Games 2020 in Tokyo. Research methods. Scientific information sources analysis, measuring the angles of the athletes’ body positions by means of a special computer program “Screen protractor”, methods of statistical data processing (calculation of X mean values and root-mean-square deviations). Results. We defined kinematic parameters of the final phase of a dive fulfillment by high-class athletes. Conclusion. It was stated that high-class athletes fulfill the final part of a flight phase with a small variability in dives both of I and IV classes, and the judges’ assessment of a dive to a greater extent, reflects an overall impression of a dive, its height, rotation speed and accuracy of the final phase fulfillment. Therefore, I class jumps are rated higher than IV class dives.
