The importance of the research lies in special exercises using different resistance on youth soccer players U19 for developing some physical abilities as well as identifying which resistant is better sand or weights on the level of abilities development. The researcher used the experimental method on (20) players who were divided into two equal experimental groups; the first group (10) players trained on sand ground while the other (10) players trained on grass field using sand weights. Special training were designed for each group with special intensity, frequency and volume. The research lasted for (10) weeks with 3 training sessions per week and each session lasted for (40 – 45) minutes. The data was collected and treated using proper statistical operation SPSS to conclude that special exercises using sand and weight developed all types of special strength (explosive strength, strength - speed, strength endurance) in both groups. Finally the researcher recommended the necessity of coaches paying attention to using different resistance (sand/ weights) to improve physical abilities of players.

Abstract The aim of this study was to examine the anthropometric and fitness characteristics of soccer players with different positional role. Although, players’ skills are not equally distributed in each position, at elite soccer they have to perform each skill at a sufficient level. However, coaches expertise those from an early age in specific positions without giving them an holistic individualized training. In the study participated 312 Greek players aged 6 to 17 (M= 11.89; SD= 2.33) of 5 age groups (group U7-U8; group U9-U10; group U11-U12; group U13-U14; group U15-U16; group U17). Anthropometric (height, weight, body mass index and body fat) and fitness characteristics (flexibility, vertical jump, running speed, agility and VO2max) of participants were measured. The study showed that goalkeepers and central defenders tend to perform worse than players of the other positional groups in most of their fitness characteristics for almost all the age groups. Furthermore, many tendencies were observed in anthropometric and fitness characteristics between players with different positional roles. This study provides suggestions to coaches regarding their practice of positioning players according to their anthropometric and fitness characteristics for a short term success.

This study aimed to identify characteristics of match performance and physical ability that discriminate between elite and subelite under-14 soccer players. Players were assessed for closed performance and movement, physiological responses, and technical actions during matches. Elite players covered more total m·min−1 (115.7 ± 6.6 cf. 105.4 ± 7.7 m·min−1) and high-intensity m·min−1 (elite = 14.5 ± 2.3 cf. 11.5 ± 3.7 m·min−1) compared with subelite players. Elite players also attempted more successful (0.41 ± 0.11 cf. 0.18 ± 0.02) and unsuccessful ball retentions·min−1 (0.14 ± 0.04 cf. 0.06 ± 0.02) compared with subelite players. Elite players were faster over 10 m (1.9 ± 0.1 cf. 2.3 ± 0.2 s) and faster dribblers (16.4 ± 1.4 cf. 18.2 ± 1.1 s) compared with subelite players. Speed (10 m) and successful ball retention·min−1 contributed to a predictive model, explaining 96.8% of the between-group variance. The analysis of match performance provides a more thorough understanding of the factors underlying talent among youth soccer players.

The research aimed at designing exercises using different resistance in soccer players under 19 years old as well as identifying the effect of these resistances on some physical abilities development in soccer players under 19 years old. The researchers used the experimental method on (24) players. Field procedures included physical abilities tests followed by the main experiment (varied resistance style) including plyometrics, rubber ropes, and sand floor exercises then ended with posttests. The researchers collected the data and treated it using SPSS to conclude significant differences between pre and posttests in explosive speed and strength while there are no differences in strength – speed. The researchers concluded that these exercises have positive effects on the subjects under study. Finally, they recommended using these exercises on soccer players of all age groups as well as making similar studies on other physical abilities, basic skills, physiological variables, and other sports.

Change of direction (COD) is a performance-limiting factor in team sports. However, there are no exact definitions describing which physical abilities limit COD performance in soccer. Nevertheless, different COD tests are used or have been recommended as being equally effective in the professional practice of measuring COD performance. Therefore, the aim of this study was to evaluate the relationship between different COD tests, and to test the independence and generalizability of these COD tests in soccer. As such, 27 elite youth soccer players were randomly recruited and were tested in different COD tests (i.e., Illinois agility test (IAT), T agility test (TT), 505 agility test (505), Gewandtheitslauf (GewT), triangle test (Tri-t), and square test (SQT)). Bivariate Pearson correlation analysis was used to assess the relationships between the COD tests. The Benjamini–Hochberg method was used to control for the false discovery rate of the study at 0.05. This investigation calculated explained variances of 10% to 55% between performances in the different COD tests. This suggested that the tests covered different aspects or task-specific characteristics of the COD. Therefore, coaches and sport scientists should review and select different tests with a logical validity, based on the requirement profiles of the corresponding sport.

El objetivo de este estudio fue comparar las demandas físicas que exigen dos modalidades de juego distintas en fútbol a jugadores jóvenes (Fútbol 7 (F7) vs. Fútbol 11 (F11)). 26 sujetos de entre 12 y 15 años fueron valorados durante la primera parte de 8 partidos (4 de F7 y 4 de F11). Los datos se midieron con GPS de 1 Hz. Los principales resultados fueron: 1) el rendimiento de carrera fue superior (en términos absolutos) cuanto mayor edad, tanto en F7 como en F11, 2) en general, para el mismo grupo de edad, el F11 supuso mayor demanda física que el F7, 3) en la misma categoría, hubo mayor demanda física en el grupo de mayor nivel (sólo en F11). En síntesis, los resultados mostraron una mayor demanda física del F11 frente al F7 en la mayoría de las comparaciones realizadas. Dicha demanda de carrera también aumentó conforme lo hacía la categoría según la edad, sobre todo se encontraron diferencias entre Infantil B (infantiles de primer año en la categoría) y Alevín. Todo esto podría indicar que el cambio de superficie de juego que se da al pasar de categoría alevín a categoría infantil (y por tanto, de F7 a F11) podría ser demasiado drástico, ya que en muy pocos meses los jugadores cambian de categoría. Por tanto, hemos llegado a la conclusión de que podría ser conveniente establecer un terreno de juego de dimensiones intermedias entre F7 y F11 en la categoría infantil que haga el cambio de dimensiones más progresivo.Palabras Clave: fútbol, fútbol 7, demandas de carrera, GPS, jóvenes.Abstract: The aim of this study is to compare the running requirements of playing football in two different modes with youth players (Football 7 (F7) vs. Football 11 (F11)). 26 individuals (12-15 years old) were measured during the first half of 8 matches (4 of F7 and 4 of F11). Data was collected with 1 Hz GPS. The main results were: 1) running performance was higher (in absolute terms) in the oldest players, both in F7 and F11, 2) generally, within the same age group, F11 was physically more demanding than F7, 3) within the same category, the highest level group obtained the greatest physical exertion (only F11). To sum up, results showed that F11 necessitated greater physical exertion than F7 in the majority of comparisons. This running demands also rose according the age and, above all, differences were found between «Infantil B» (under-13, playing F11 according to the rules for the first time) and «Alevín» (under-12). These discoveries may indicate that the change of the dimensions of the pitch from «Alevín» to «Infantil» (therefore, from F7 size to F11 size) may be too drastic because players change from one category to the other in only a few months. We therefore suggest that it may be convenient for the «Infantil» players (under-13 and under-14) to establish a pitch with intermediate dimensions between F7 size and F11 size. This would make the step from one size to the other more progressive in terms of physical exertion.Keywords: football, football 7, running requirements, GPS, youth players.

AbstractWithin the context of the transition from junior-to-senior sport, this study aims in first place to explore differences in young Spanish elite soccer players based on the importance given to getting different achievements in their future (including sport, studies and private life) and, in second place, to explore differences among those players in levels of passion, motivation and basic psychological need. 478 elite youth soccer filled out a questionnaire based on the presented theoretical models. A cluster analysis shows a sport oriented group (N = 98) only interested in becoming a professional, a life spheres balance group (N = 288) characterized by balancing the importance of achievements in the sport sphere, as well as in education and a private life and a group (N = 91) only interested in private life achievements. The life spheres balance group shows higher levels of harmonious passion (η2 = .06, F(2, 475) = 9.990, p < .001) than the players of the other groups. The life spheres balance group shows higher levels of autonomous motivation (η2 = .10, F(2, 475) = 13.597, p < .001), autonomy (η2 = .07, F(2, 475) = 6.592, p < .01) and relatedness satisfaction (η2 = .07, F(2, 475) = 5.603, p < .01) than the sport oriented group as well as lower levels of amotivation (η2 = .04, F(2, 475) = 6.665, p < .01) than the private life oriented group. This study suggests players who perceive equal future importance in their life spheres appear to be more resourceful than the other two groups regarding athletes’ internal resources, such as passion and motivation, to cope with the transition to professional soccer.
