Objective of the study was to substantiate the structural and functional relationships of women’s heptathlon disciplines and establish the key elements in this structure.
The competitive performance of the strongest heptathletes at the world championships for the whole their history - from 1983 to 2017 was analyzed. 128 results in women's heptathlon were statistically processed. Pearson correlation analysis between the results in all-around events was carried out. In cross-country heptathlon disciplines a decrease in the run time value corresponds to an increase in the result; therefore, the scores in each discipline were taken from the official competition protocols, along with the amounts calculated for the correlation analysis between groups of heptathlon disciplines. When interpreting the obtained correlation relationships, only high, noticeable and moderate correlations on the Chaddock scale were taken into account. Weak correlations (–0.3 <r <0.3) were not considered in the study.
 The study revealed the structure of the interrelation of disciplines and groups of disciplines in women’s heptathlon. The 200 m run and sprint group are the link in the structure. It is established that the jump and sprint groups are of “stimulating” effect for other types of action, and the throw group is of - “oppressive” effect.

Keywords: interrelation of heptathlon disciplines, correlation analysis, intergroup relation, heterarchy.
