Abstract
Performance in athletic decathlon is expressed in points. Individual performance development, point structure of performance in decathlon can serve as a means of assessing the possibility of further development of the decathletes performance.
We retrospectively compiled the individual performance development of world record holder Kevin Mayer. We counted the point structure of his decathlons and determined the percentage of performances in sprint, jump and throwing disciplines in overall performance.
We have identified the development of Kevin Mayer's potential performance and the development of his efficiency of competitive performance (ECP). His potential performance before the world record was 9246 points and during his career proved he is able to reach almost 100% of the ECP.
We therefore estimate the high probability of improving the current world record by Kevin Mayer by 2020
