The paper is intended to do a correlation analysis of the indices of the Squat jump test specific to the senior martial arts athletes. Ascertaining research was conducted to this effect. The research involved 11 senior athletes practicing Pankration martial arts, aged from 20 to 40 years, within the Shin Daito Sports Club of Bucharest, in collaboration with the Romanian Federation of Pankration Athlima. Research methods used: method of bibliographic study, method of tests, method of experiment, statistical-mathematical method, tabular and graphical presentation of data method. The test method used the Tanita scale for body composition analysis and the Opto Jump Next system for determining the maximum power (explosive strength) at the level of lower limbs, spatio-temporal coordination and jumps height. The results of the research highlight the anthropometric data, the body composition and the values of Squat Jump test indices in terms of flight time and height in senior martial arts athletes. The results of the correlation analysis between the indices of the Squat Jump test highlight strong connections 80% at p<0.001 and 20% at p<0.01. The relation between the anthropometric indices and the Squat Jump test indices shows 33.3% strong connections (at p<0.01 and p<0.05); the other connections are insignificant at p<0.05. In conclusion, the correlation analysis between the Squat Jump test indices, anthropometric indices and body composition indices in the senior martial arts athletes highlighted the degree of the relation between the test indices and the influence of the anthropometric data on these ones.
