Summary/Abstract: Since the 90s of the twentieth century, the sports diagnostics have started applying principles of fuzzy logic, which offers a different quality approach to data analyses than the standard probability approach. The aim was to create a process for evaluating each test of the battery of tests TENDIAG1 on the principle of fuzzy theory. Based on similar published research and expert reviews we constructed membership functions for individual tests and proposed an algorithm to calculate the boundary points. Procedure for the construction of membership functions is demonstrated in the research data set of the tennis players aged 11-12 years (n = 187), specific evaluation of the results was performed at the sub-set of randomly selected tennis players (n = 25) of the set. For the final evaluation of the results of the test battery we used the method of aggregation of partial results.
