The interrelationship of biomechanical parameters of the elements in the execution techniques of specific types of heptathlon

The purpose of the study is to determine the interrelationship of biomechanical parameters in the execution technique of specific types of heptathlon. Research methods: analysis of scientific and methodological literature, biomechanical analysis, methods of mathematical statistics. Research results and conclusions. The article presents the results of biomechanical analysis of the technical elements of specific types in the heptathlon by the strongest athletes in the world. In hurdle running, high jump, long jump, and javelin throw, parameters that correlate with the results have been identified. The characteristics of the rhythm and tempo of executing the basic technical elements in each type have been determined, as well as the interrelationship between the rhythmic-temporal structure of hurdle running and long jump, high jump, and javelin throw.
