Abstract
Performances in athletics combined events are expressed in points. Individual performance development, point structure of the performance in the decathlon can serve as a means of assessing the prospects of young decath-lete.
We retrospectively from individual performance developments of six decathlete with finished careers calculated the structure of their performance and determine the percentage of performance in sprint, jumping and throwing disciplines on overall performance. We estimate high probability of improving the current world record by Asthon Eaton in 2016.
Adam Helcelet is well placed to achieve in the next three to five seasons performance from 8500 to 8800 points. Junior performances of our two decathletes (Jiří Sýkora a Jan Doležel) show that they can reach peak performance in senior decathlon.
