Abstract

The project was designed to collect data about junior football players using complex instrumental measurements. Agility is the ability to move easily and quickly; it infers rapid onset, sudden stops and changes in direction. The execution of these requires complex skill set. In modern football, this factor is considered the most important one in terms of efficiency. Several previous studies have, with no significant results, tried to find a link between individual skills and agility. In the present research we were looking for answers to what factors influence agility among junior football players.According to the of the movement-structure analysis of these tests, it is possible, that separately they do not cover the whole scale of movement patterns which could be present during a match. Because of this, we promoted two new variables: There are the "Agility without ball" and the "Agility with ball". This test of movement structure contains all the components which could be expected of the players during a match, such as changes of direction, dribbles, using the dominant and subdominant leg separately and optionally.In modern football, agility is an extremely complex skill, and the exact structure of its performance components is hard to define. The factors influencing players' agility should be emphasized and methodically developed in youth training in the light of future efficiency.
