Basketball throws are fundamental and final actions in the offence. When in the case of performance of any other technical actions, certain more or less signifi cant errors are allowable, to play a perfect game, basketball shooting accuracy is the condition of the utmost importance and necessity. The basketball shooting accuracy is improving gradually when motor behaviour technique is being developed and a "feel of basketball shooting" mastered. The "feel of basketball shooting" means summing up the basket-shooter distance and the force being applied during the shooting action. When special aids for basketball shooting (special balls, fastening devices) are applied during practical training sessions, the consistency of basketball shooting motor behaviour should improve, and, consequently, the accuracy of free throw performance should improve as well. The aim of the research has to establish and evaluate the effect of special aids on the change in basketball shooting accuracy. Thirty six girls basketball players aged 14-15 years (n = 36) of adequate level of sports performance participated in the experiment. They were divided into two groups: the experimental (n = 18) one and the control (n = 18) one.After performing the experiment, having carried out the 2 tests of free throws, it has been established that the number of scoring free throws made by the control group has improved by +1.9 throws, however there has been no significant difference in the indices (p > 0.05). The free throw performance results during the 2nd testing improved markedly in comparison to those of the 1st testing (p < 0.05). When applying special aids for basketball shooting (a special fastening device for a non-shooting hand and a special training ball), the best result has been demonstrated by the third experimental group that executed its free throws using both the fastening device and the special ball. The number of scoring shots made by this group has improved from 52.3 ± 9.1 to 79.0 ± 9.8 (+26.7 scoring throws). The free throw accuracy indices of the three experimental groups in comparison with the control group indices have improved statistically significantly after performing the experiment, therefore, application of non-traditional aids to the formation and mastering the skills of this technical action appears to be effective
