The goal of this master thesis was to determine the differences in the situational efficiency of winning and defeated teams in relation to the final outcome of the match, i.e. victory or defeat of women's handball teams at the Olympic Tournament in Rio 2011. in the preliminary part of the competition. There were 12 teams played in two groups, 6 teams in group A and 6 in group B. The sample consisted of 28 matches played with the same number of winners or defeated teams. For the purposes of research, 17 variables were used, of which 14 for the attack phase and 3 for the defense phase. The frequency of successful and unsuccessfully executed technical - tactical elements, which were also observed variables, was recorded through the notational analysis of each played match. To determine the difference between winning and defeated teams, the Mann - Whitney test was used. It was established that there are significant statistical differences in the 4 observed variables, three related to the attack phase and one that refers to the defense phase: 9-meter shot failed - ŠUT9MNE (p = 0.00); Shot from the counterattack successfully - ŠUTKOUS (p = 0.01); blocked shot - BLOKŠUT (p = 0.01); assists – ASISTEN (0.02). Winning teams with a very mobile and organized defense have a greater number of seized balls in the form of blocking the shot and opening up a chance to achieve easy goals from the counterattack. Winning team organize a group and individual tactic much better, where is the space created for assist or last pass before the shot. Also, the shot from the outside positions of the winning teams are much better which suppose better preparation of the attack but also the high level selection of shot on goal. It is needed to do much more of this kind of analysis in a women's handball because the demands of handball games growing up from day to day.
