The heptathlon is a combined event in athletics consisting of seven athletics events, where the most versatile athletes compete . The heptathlon competition is held over two constructive days, and the winners are determined by the combined performance in all . On the first day the competitors do 100 m hurdles, high jump, shot put and 200 m . On the second day they do long jump, javelin and 800 m . Performance is judged on a points system in each discipline using scoring tables, which were accepted by the International Association of Athletics Federation in 1984. Considering that the heptathlon stands for running, jumping, and throwing disciplines, the goal of the project is to determine the structure, or domination of definite single disciplines or the group of disciplines, during achieving the results in the heptathlon . According to this, the analysis of the world record of Jackie Joyner Kersee and the heptathlon Olympics winners from 2000 to 2016 was done in this project . The research results show that the results achieved in running and jumping disciplines play the crucial role in the achieving the best results in the heptathlon, and the world record of Jackie Joyner Kersee is the result hard to be achieved in the future.
