Annotation. Decathlon in track and field is a complex project, by the specific individual components, but does not mean that all of the simple sum of the individual, it is by the specific combination of a single indivisible integrity of the competition. All-around track and field project to some extent a reflection of a country’s overall level of athletics. Ukraine through the world’s best all-around athlete with the differences in test scores to prove that Ukraine and the world there is a big gap compared to the athletes. In order to find differences between the subjective and objective factors and to explore ways to narrow the gap, this article attempts to the application of the theory of gray “advantage analysis” of Ukraine and the world all-around athletes compared.

По конкретным отдельным компонентам десятиборье в легкой атлетике является сложным видом спорта. Однако, его специфические индивидуальные компоненты это не простая сумма, а определенная комбинация видов в неделимой целостности соревнования. Десятиборье в некоторой степени является отражением общего уровня развития легкой атлетики в стране. Украинские лучшие спортсмены участвуют в различных представительных соревнованиях и их результаты имеют большой разрыв с лучшими атлетами мира. Для того, чтобы найти различия между субъективными и объективными факторами, а также изучить пути сокращения этого разрыва предпринята попытка применения теории серых систем «Анализ преимуществ» в сравнении десятиборцев Украины и мира.

Introduction
Decathlon is a technical track and field complex. Subkey is a game, and operation of technology, and competition in a long time running, jumping, voted to change rapidly, and the rules of strict high-skill, high-intensity comprehensive sports track and field. Athletes not only need to have a good basis for the special training and a comprehensive physical fitness level and multi-purpose, all the technical and tactical proficiency, but also have the courage to struggle and indomitable will of good quality to compete with the ability to respond rapidly moving. Although the campaign
has been by all the individual specific component, but it will not mean a simple sum of all individual, it is by the specific combination of a single indivisible integrity of the competition. In the competition, determine the outcome of the principle of athletes to participate in the competition is the purpose of accrued points, that is, to decide the winning score. With the level of all sports, athletes overall strength, the lack of competition in any one of them scored, all-around game to lose its meaning. All-around track and field project to some extent a reflection of a country’s overall level of athletics. At present, most of all-round study of movement for allround sports training, the all-powerful selection of athletes, as well as technical analysis of elite athletes. Lack of all movement between the sub-item total score of the relationship between the research and analysis
Research purposes
Application of gray system theory “advantage analysis” of Ukraine’s best player and the world decathlon best-owned projects, respectively, for comparison, to identify their respective advantages and disadvantages related to the project and its relationship with total score of the objective laws. In order to identify differences in the subjective and objective factors, and seek to narrow the gap.

Advantage Analysis
Analysis of the advantages is the gray system theory in the correlation analysis, multiple comparison with a number of reference curves constitute a curve associated matrix, matrix, through its calculation of the quantitative factors, and then a large number of relevant factors to distinguish the main, sub, inferior factors that determine the course of comparison. That is, once again the relative of all the factors which impact the overall schedule has about the process than the quantitative. Application of gray relational analysis theory, the principle of the individual all-around in the correlation of the total order to determine the size of the larger correlation for the advantages of their projects, their correlation times are the advantages of the project for the meeting, who owned a small correlation projects of non-edge. Through our country and the world’s top eight all-around advantages of athletes and non-edge contrast of the correlation analysis, analysis to calculate the weight-related values can be found on their respective total scores of the key factors affect the host, training in the use of reasonable methods to obtain better training results, to improve the level of all sports.

As can be seen from Table 4: The advantages of the project, Ukraine’s advantages include the field events and track projects to the long jump for the greatest advantage, that advantage with the world’s best players and similar. Total score from the point of view, very different, a difference of 1839.88 points. Shows that the level of Ukraine’s movement compared with the world players, the larger the gap, it is necessary to improve performance, enhance the physical fitness training, and individual skills training.
Conclusion
Through Ukraine and the world’s best decathlon performance comparison analysis, that the Ukraine’s shot put and pole vault is the weakest of the non-edge projects, the world’s best players all the advantages of these two projects, they should focus on the development. In training should be planned and reasonably arrange the rhythm of the son of the training, the sub-item will be able to be co-ordinated development, thereby enhancing the overall training effectiveness, to world-class forward.

The future, we can use the gray system theory analysis of the ways to further training in the training of various indicators of the extent of the impact on the results, in order to provide a better all-round training theory.
