| Popis | Heading is one of the basic game activities in football but it is still discussed in term of risk of health problems, especially cumulative head trauma. This study aims to find out how to improve the supervision over heading performance during learning process in youth footballers using an accelerometer. The research sample consisted of 63 footballers from age groups U11 – U17. Each person executed headings of a ball dropped from 0.5 m, 1 m, and 1.5 m. A triaxial accelerometer fixed to the back of the head was used in the measurements. For individual groups of participants, an approximate linear increase in peak head acceleration was observed for an increase in ball drop height (R2 = ± .99). Furthermore, strong correlations in the maximum head acceleration parameter amax were found between the attempts from all three heights. A linear decrease in peak head accelerations were observed with increasing age of the participants. The core importance lies in between relations of measured variables that show changes during acquisition of skills in heading in young footballers. Regular control accelerometer measurements can help determine the level of acquired skill and serve as an appropriate tool for preventing overloads or injuries of individuals. |
