To determine the influence of the situational efficiency of goal shooting on the prediction of the results of the first phase of the competition at the U19 World Handball Championship in 2019 it was analyzed 60 matches, played by national teams that have qualified to this championship. It has been observed 14 variables of situational shooting efficiency with seven positions, from which usually shoots in the attack phase of the handball game. This set of variables was set up so that was analyzed a successful and unsuccessful shot on goal from all positions. The criterion was a binary-defined result of handball. For all analyzed variables were calculated basic descriptive indicators. At this stage of the competition, teams have shot an average of 45.66 times from seven analyzed positions in the game of which was an average 27.53% of successful and 18.14% unsuccessful shots. The percentage of shooting success was 60.09%. The mutual correlation of the predictor variables was calculated with the classical correlation method. The results showed that 7 correlation coefficients are significantly at a more stringent inference level and 4, at a milder inference level. To evaluate the predictive impact of a set of variables which are evaluated situational efficiency within the binary defined result of handball game, the Logistic Regression was used. Its results are shown that the applied set of predictor variables covers between 57.3% and 76.4% of the common variance. The result of the Hosmer & Lemeshow test confirmed the high predictive value of the selected set of variables. The calculated B values and the individual contribution of each of the analyzed predictor variables indicate that the six variables have a statistically significant contribution to the prediction of the results of handball matches of this stage of the World Junior Championships. The highest partial contribution to the prediction of the result of handball matches was shown by the variable for evaluating the successful fast breaks shot. The high individual predictive value was also shown by the variable for evaluating successful shots from the back positions (9m shot - successfully). This phase of the competition was dominated by national teams that play fast handball, with a large number of fast breaks and fast transformations from one phase of handball play to another.

In order to make good-quality plan and program in any top class sport especially to realize it, it is necesseray to have knowledge in specific requirements of certain sport or its discipline but also, beside that, knowledge of relevant skills, characteristics and knowledge of player or group of players. Therefore, it is important to determine and follow situational effects which will help in succesful diagnosis of initial transitive and final state of training in order to reach good sports results. Aim of this research is to determine and show success of volleyball club based on situational efficiency season 2012/2013 where it is expected link between success and situational effiency of volleyball club.
