Abstract

The aim of the research was to analyse physical development, physical preparedness and capacity of some functions of football players’ of age 15-16 and to form reference scales of analysed attributes. 84 pupils of age 15-16, who had been attending football trainings for 2-3 years in Vilnius, Klaipėda, Šiauliai, Panevėžys, Marijampolė, Rūdiškės sport schools, were selected by the method of random sampling in 2007 second half. Physical development was tested and analysed by establishing jump height, 5.30-m running speed without ball and by dribbling it from standing start, by using photo start and photo finish and by establishing 30-m running with running up time span. Two tests of measuring quickness were applied: jumping from the middle of hexagon outside it (Stonkus, 2002) and shuttle-run (EUROFITAS, 1993). Physical capacity was measured by establishing: single muscular contraction power (SMCP) (Bosco, 1983), anaerobic alactic muscular power (step ergometry) (AAMP), anaerobic alactic and mixed alactic glycolytic power, with applied 30-s veloergometer test on max exertion (Wingate) (Inbar, Bar Or, 1986). Aerobic capacity was measured by applying the method of max O2 consuming (VO2max) evaluation (Astrand, 1960). Functional capacity of blood circulation was estimated by establishing pulse rate (PR) while lying and by the Roufier index. Psychomotoric functions were analyzed by establishing the duration of simple psychomotoric reaction to light stimulus and minimal movement frequency in 10-s. The methods of the research are set out by Skernevičius, Raslanas, Dadelienė (2004). It was estimated that somatic and physiometric indices of physical development of Lithuanian boys of age 15-16, who attend football trainings, are very close to the indices of those of the same age who are less physically active. Analysed young football players did not have high indices of running speed, high jump and quickness. The indices of anaerobic power also were not any higher than those with low physical activity. Comparative indices of VO2max were equal to the data of Lithuanian schoolchildren research. Functional capacity of blood circulation system was at average level. The data of psychomotoric research did not have considerable supremacy over non-trained persons. The very essential problem of football players’ selection and purposeful training have been highlighted. Lithuanian Football Federation and other Sport organizations, with the help of scientific institutions, should pay attention to it. Reference value scales of physical development, physical and functional capacity will help to do better selection of youngsters to football schools and to evaluate their preparedness development better.
