Background and purpose Purpose. To improve the tactical interaction of players in 3x3 basketball at the stage of specialized basic training based on the use of specific improvisational exercises, taking into account the specifics of the players' competitive activity. Material and methods Two groups of basketball players at the stage of specialized basic training, 12 athletes each, took part in the research, taking into account the lack of reliability of differences in the analysed indicators at the beginning of the study (р>0, 05). All participants gave an informed consent to partake in this experiment. Descriptive statistics (arithmetic means in groups (M), mean square deviations (SD), errors of arithmetic means (m)) were calculated for each dependent variable. The Student's t-test was used to estimate the probability of differences in one feature before and after the experiment, provided that the data had a normal distribution. The Wilcoxon Signed Ranks Test (Z test) was used in case of noncompliance with the normal distribution of the data of two dependent samples. The Mann-Whitney U-test was used to compare the differences between the results of two independent samples in different tests. Results The analysis of the dynamics of changes in the teams' game performance (the changes were revealed in the process of analysing video recordings of games in 3x3 format competition) showed that the experimental group players increased the number of attacks per game to 20.20±2.59 and improved their performance to 12.00±2.45, which was 59.05% of efficiency. Indicators in control group remained almost unchanged, and the efficiency equalled 50.25%. The comparison of changes in all indicators in the groups after the experiment still has no statistical difference (the number of attacks - t = 0.819 at p = 0.444; of them effective - t = 1.671 at p = 0.146; in terms of effectiveness - t = 1.632 at p = 0.154). Conclusions Our proposed option for improving the tactical interactions of 3x3 basketball players, which was based on the use of specific improvisational exercises for 12 weeks' period, had a positive effect on basketball players' tactical preparedness, increasing the effectiveness of their game performance during competitive games. © Musiienko A, Tsymbaliuk Z, Olena Nesen, Ihsan F, Setiawan E, 2024.
