Abstract
The decathlon is an athletic event consisting of ten track and field events. Events are held over two consecutive days and the winners are determined by the combined performance in all. We considered the best 200 decathletes who competed in the recent Olympics games and World Championship decathlon. We have used correspondence analysis to identify the relationship between ordered individual performance and the overall performance. Canonical correlation analysis of first day events versus second day events could shed light on the change of the level of performance between the two days. Correlation analysis was used to verify relation between cumulative event rank and final decathlon rank. Therefore, we conclude that the decathlon favors those atheletes who do well at the track events to become the best players. The best players in the decathlon performed relatively poorly in the 1,500 metres, but did well in the long jump, the 400 metres and the 110-metre hurdles. Decathletes in this study have a positive correlation between overall performance and maximal excellence in a particular discipline. Thus, to compete successfully at this level, a uniform, relatively high performance in all individual disciplines is required.
