The purpose of the study was to determine the indicators of physical development and body composition of goalkeepers and outfield football players. Materials and methods. 34 football players of the Ukrainian Premier League took part in the research, including: 11 goalkeepers and 23 outfield players. The following research methods were used: generalization of data from scientific and methodical literature, pedagogical observations, medical and biological methods (anthropometry, caliperometry); methods of mathematical statistics. Results and discussion. Anthropometric measurement was carried out according to 23 indicators and the composition of football players – according to 3 indicators. The most significant difference between goalkeepers and outfield players was determined by indicators of body weight, body length and body circumferences: wrist, forearm, shoulder at rest and tension, neck, hips. Thus, the body weight index of goalkeepers was 82.9 ± 5.8 kg, and outfield players – 69.1 ± 7.0 kg; the body length index of goalkeepers was 192.2 ± 5.1 cm, and that of outfield players was 179.2 ± 6.5 cm. That is, goalkeepers are taller compared to outfield players and mostly have a larger body mass. In addition, goalkeepers are stronger and stockier than outfield players in terms of parameters. Also, the indicators of skin-fat folds were significantly different, according to the playing role of footballers (p <0.001). It was found that goalkeepers are larger in terms of the volumes in the chest, waist and skin-fat folds in the area of the lumbar region of the back. A slight difference (14%, p <0.05) was found between goalkeepers and outfield players in the indicator of the skin-fat folds of the triceps muscle. A factor analysis of the obtained results of physical development was also carried out. The purpose of this analysis was to identify the generalized anthropometric characteristics and body composition of football players of various playing roles. Conclusion. For further consideration of the received information by the value of eigenvalues that had an indicator of at least 1, four informative factors were noted: factor 1 (7.99), factor 2 (2.24), factor 3 (1.58) and factor 4 (1.12). According to the relative contribution to the total variation, which should have been more than 10%, two informative factors were identified: factor 1 – 47.0%, factor 2 – 13.2%. It was possible to identify the following most important indicators for this group of factors: body weight, body length, circumferences: forearm, shoulder at rest, neck, waist, hips, lower legs; skin-fat folds: oblique abdominal muscle, biceps brachii, thigh, triceps brachii, lumbar back; composition of the body – "net mass". In the future, the results obtained in this way will allow coaches to make adjustments to the educational and training process to improve the physical and functional fitness of football players

The research results of the physical development level, indicators of technical and tactical actions of young football players aged 13–14 of different game roles are presented. The research involved 46 young players aged 13-14 of FC "Arsenal" in Kharkov, including 6 goalkeepers, 8 central defenders, 8 wing defenders, 8 central midfielders, 8 wing midfielders, 8 forwards. The following methods were used: theoretical analysis and generalization of scientific and methodological literature, pedagogical testing, and mathematical statistics. Quantitative indicators of motor actions of young football players of 13-14 years of different game role according to the results of 10 calendar games are determined. It was established that the quality of performance of technical and tactical actions of young football players was not the same for players of different game roles. Goalkeepers mainly make long and short passes (29.8 ± 1.19 and 27.2 ± 1.16% of the total number of technical and tactical actions). The largest number of movements with the back forward, cross step and additional step was made by the goalkeeper (12.3; 7.0; 2.6% of game actions per game), which were statistically significantly higher in relation to all field players (p <0.001). Goalkeepers during the game perform more jumps (32.4 ± 1.48% of all motor actions) and throwing the ball (26.4 ± 1.48%). Goalkeepers’ indicators of speed and power capabilities (in the test "vertical jumping") were statistically significantly superior (p <0.05) to players of all other lines. The correlations between the test indicators that reflect the level of goalkeepers’ physical fitness were determined. A statistically significant correlation was established between the indicator "vertical jumping" and running 30 m (ρ = -0.82, p <0.05), indicators of starting and distance speed (ρ = 0.84 and ρ = 0.86, p <0.05), the indicator "running 10 m on the move" with a 6-minute run, which characterized the overall endurance (ρ = -0.83, p <0.05). Goalkeepers are characterized by the relationship between all technical and tactical actions of the game and the level of motor skills development, namely the statistical significance of the correlation of speed and speed-power qualities with technical and tactical indicators.
