One of the main elements of a successful performance in a football match is the motor skills and situational performance of the athlete in the attack and defense phase. The primary goal of the thesis is to determine the influence of the preparatory period on the situational motor skills of football players in the U-16 category. In this research, 12 male respondents participated in 5 tests: winding running (slalom), speed of leading with a change of direction at a right angle, speed of leading (slalom), hitting the rock after the ball bounced off the surface and straight-line accuracy with the foot - vertical target. Testing was conducted in the U-16 age group (cadet age) with players from the Nk “Sloga” Gredelj club. 2 tests were conducted, first at the beginning of the preparatory period (initial) and second at the end of the preparatory period (final). Collected data after the test were analyzed in the “Statistica” computer program with a t-test for dependent samples. Certain descriptive indicators were also used to describe the obtained results, such as: arithmetic mean (AS), total range (MAX and MIN), standard deviation (SD) and indicators of the curvature of the distribution (skewness and kurtosis). Based on the conducted research, it can be concluded that, after the preparation period, U-16 soccer players achieved similar results of situational motor indicators in the majority of selected tests, from which it can be concluded that a young athlete needs a long-term systematic training process under a precisely defined plan and program.
