Discipline homogeneity based on the most successful decathlon scoring placement

Athletic Decathlon (all-around) is physically demanding athletic competition that is scored according to a special IAAF tables. and the winner is the competitor who wins the most points. However. some authors give different views on the contribution of individual disciplines total pointing result. or grouping similar disciplines. favoring those disciplines that are based on more motor potentials athletes creating homogeneous groups (clusters). This study analyzed ten world record holder in all-around athlete of the 1984th to 2016th Its aim is to determine the number of clusters. or the level of homogeneity between disciplines. Data were analyzed using hierarchical cluster analysis which confirmed the existence of nine clusters integrated into three major groups. In the first group defined with four clusters were distinguished discipline (100m-110m-400m-Pole Vault-LJ) that the representatives of the movement of sprint and high jump type (anaerobic capabilities). The second group of four clusters also have defined mainly all three throwing disciplines as primary (SP, DT, JT) and one rebounds as secondary (HJ) that defines the strong discipline of speed and explosive character. The third group is defined by discipline 1500m as the farthest point in the athletic decathlon. This is a confirmation that this is a typical aerobic ability. under the auspices of functional mechanisms. This score is confirmed some previous research on the number of clusters and partial homogeneity between disciplines that are under the umbrella of the same energy potential and possible benefits of sprint and jumping with respect to throwing disciplines.
