In this paper, the testing of various manifestations of agility in futsal, a sport characterized by intense activity, rapid changes in tempo and complex technical-tactical elements, was carried out. The aim of the paper is to determine whether there is a connection between morphological characteristics and agility tests and whether there is a difference between minor and adult players in the performance of agility tests. The sample of respondents consisted of junior futsal club Osijek, which included a total of 18 players of average age (17.06 ± 1.16 years), height (177.73 ± 9.03 cm) and mass (69.18 ± 8.66 kg). The sample of variables consists of six tests. Two tests are related to morphological characteristics (body height and body weight), while four tests are related to agility. The research results showed statistically significant moderate to high correlations between different variables (p < 0.05). Analysis of group statistics reveals that minor players on average achieve better results in most tests, except for the T-test of agility and reactive agility test knowing that they go left first, where adult players record better results. There are statistically significant differences in agility between minor and adult players in the 10-meter sprint test, which measures a certain aspect of agility, minor players proved to be superior to their adult counterparts, with an average time of 1.72 seconds, which is statistically significant (p < 0.05) faster, the same applies to the reactivity tests (first on the right) and the reactivity test. These results suggest that minor players have an advantage in some manifestations of agility and reactivity compared to adult players, which may be crucial for planning training and developing strategies to improve player performance in the future.
