Purpose: The purpose of this study was to compare the temporal variables of the jump shot in three conditions: regular performance and imitation with and without visual information. Methods: Twenty youth male basketball players (age 15.9 ± 0.7 yrs., experience 7.7 ±1.8 years) voluntarily participated in this study. 300 jump shots at 6 meters from the basket were taken for each of three different conditions: regular jump shot after receiving a pass: imitation with open- and covered eyes. A sleeping mask was used to blindfold the shooter. According to the shooting accuracy of the regular jump shot performance players were split into three groups: 1) >50%: 2) 30-50% and 3) <30% shooting accuracy. All attempts were videotaped from the side view with a Nikon D7100 camcorder set at 60 Hz frame rate. The duration of jump shot phases (Catching. Sitting down. Jumping up. Shooting. Follow throw) and the whole activity were measured by .Kinovea" program (0.8.26) and Microsoft Excel 2016 were used for data processing. The data obtained were analyzed using descriptive statistics (Mean. Standard Deviation. Coefficient of Variation). The equality of variation and significance of the differences was controlled by F-test and T-test. Results: The main results indicate that the duration ofthe .Sitting down" phase decreased significantly (p< 0,001) under imitation conditions with open (0.15 s +/- 0.05) and closed (0,14 s +/- 0.06) vision compared with regular performance (0.19 s. +/- 0,06) while the duration of the .Jumping up" phase was reliably (p< 0.001) extended from 0,15 s +/-0.04 in regular performance to 0.19 s +/- 0.08 at imitation with open and covered 0,19 +/- 0,07 eyes. Conditions of both shooting imitations highlighted statistically significant difference between the first (>50%) and third (<30%) group in .Catching", .Sitting down" and .Shooting" phases (p <0.05). A group with higher shooting accuracy performed the above mentioned phases with longer temporal indicators and a lower coefficient of variation. Conclusion: On the basis of the results we can conclude that youth male basketball players with higher shooting accuracy are more stable in the imitation of jump shot technique and show longer duration in .Catching". .Sitting down" and .Shooting" phases in comparison with players showing lowest accuracy.
