Abstract
The purpose of this investigation is to determine age dynamism of reactive agility in young football players, thus specifying the impact of sport training on the level of reactive agility of players. 112 young male football players playing for the football club in Nitra, Slovakia volunteered to participate in the study. Another goal was to clarify the age dynamics of performances in the monitored groups of football players and to find out the mutual relationship between the two types of agility. Trends in sport performance and relationship of both kinds of agility were observed in 6 teams of different age categories (U11 up to U16). In order to fulfil the aim of the research two different motor tests for running agility (Illinois agility test) and reactive agility (Fitro Agility Check) were selected. For the realization of Fitro Agility Check test, a computer with the necessary hardware and software, and measuring device Fitro Agility Check were used. To evaluate the relationship between the observed variables (Illinois vs FAC), we used Spearman's correlation coefficient rs (-1 ≤ rs ≤ 1) to perform correlation analysis in SSPS statistical software. We used a significance level of 0.01. The results of this study provide evidence of stabilization of performance with the growing age of players at the level of both types of agility and a dynamic increase, especially after the age of 13. Low values of correlation coefficients (from r = - 0.570 to 0.503) indicate indifferent determinants in running and reactive agility. Since low causal-consequential relationship between reactive and running agility was found in the observed football teams, there is a necessity in the sports training to differentiate between specific means for the development of the so-called pre-planned and reactive agility.
Highlights
In recent times, a top sport is characterized by a high sports performance, perfect technique, high level of motor skills and abilities, placing high demands on motor, psychological and physiological aspects of an athletes personality
Basic characteristics of the measure of position in tests Illinois agility and Fitro agility check are presented in Tables 1 and 2
When assessing the level of reactive agility in young football players we can state that there is a similar trend in the changes in the level of this indicator (Figure 2)
Summary
A top sport is characterized by a high sports performance, perfect technique, high level of motor skills and abilities, placing high demands on motor, psychological and physiological aspects of an athletes personality. The core content of sports preparation gradually passes from quantity to quality, from general to specific means. Trainers and coaches search for more effective means of developing skills and abilities, focusing on the more effective exploitation of training time. The quality of sports training rests on the exploitations of „sensitive periods“ for the development of motor prerequisites crucial for the given sport. Sports games require a high level of specific movements, represented by perfect mastering of the technique of individual skills. Athletes with a high level of anticipation, mental processes, the speed of decision-making, show predominance at the effectiveness of their motor performance
