Significant structural, developmental, and financial constraints exist in Scottish soccer that may predicate a different approach to talent identification and development. To our knowledge, no published reports exist evaluating the prevalence of the relative age effect (RAE) in Scottish soccer players. Consequently, the aim of this study was to investigate the prevalence of the RAE among varied playing levels and ages of male Scottish youth soccer players. Birthdates of male youth players (n = 1,230) from U10 to U17 age groups and from playing levels: “Amateur” (n = 482), “Development” (n = 214), and “Performance” (n = 534), alongside a group of male Scottish senior professional players (n = 261) were recorded and categorized into quartiles (Q1 = January–March; Q2 = April–June; Q3 = July–September; and Q4 = October–December) and semesters (S1 = January–June and S2 = July–December) from the start of the selection year. Birthdates were analyzed for: (a) each playing level and (b) each age group irrespective of playing level. For the varied playing levels examined, an RAE was evident in “Development” and “Performance” playing levels only at youth level. When examining each age group, an RAE was observed in U12–U17 players only. While there was a slight asymmetry favoring Q1 born senior professional players, the RAE was not present within this group of our sample. Results from our study suggest that a bias in selecting individuals born earlier in the selection year may exist within male soccer academy structures, but not at amateur level. The asymmetry favoring chronologically older players at youth but not professional level questions the efficacy of this (un)conscious bias within male Scottish soccer players.

AbstractThe fundamental tactical principles of the game of soccer represent a set of action rules that guide behaviours related to the management of game space. The aim of this study was to compare the performance of fundamental offensive and defensive tactical principles among youth soccer players from 12 to 17 years old. The sample consisted of 3689 tactical actions performed by 48 soccer players in three age categories: under 13 (U-13), under 15 (U-15), and under 17 (U-17). Tactical performance was measured using the System of Tactical Assessment in Soccer (FUT-SAT). The Kruskal Wallis, Mann-Whitney U, Friedman, Wilcoxon, and Cohen’s Kappa tests were used in the study analysis. The results showed that the principles of “offensive coverage” (p = 0.01) and “concentration” (p = 0.04) were performed more frequently by the U-17 players than the U-13 players. The tactical principles “width and length” (p < 0.05) and “defensive unit” (p < 0.05) were executed more frequently by younger soccer players. It can be concluded that the frequency with which fundamental tactical principles are performed varies between the gaming categories, which implies that there is valuation of defensive security and a progressive increase in “offensive coverage” caused by increased confidence and security in offensive actions.

AbstractIndividual differences in biological maturation present challenges for coaches involved with youth soccer players. Youth in the same chronological age group vary in terms of stage of maturity (pre, circum- and post-pubescent) and rate of growth, but how this affects coaches’ evaluations of player performance is unknown. The aim of this study was to compare youth soccer coaches’ evaluations of players match performances before, during and post growth spurt in a professional English soccer academy across four seasons. Two hundred and seventy-eight male soccer players in the under-9 to under-16 age-groups had their performances evaluated by their coach on a 4-point Likert scale. For each game, players were categorised by their maturity status estimated using percentage of predicted adult height at the time of observation. A one-way ANCOVA controlling for the level of opposition and game outcome revealed that coaches’ evaluations declined from the pre- to during growth spurt stages, however, this was only significant in the under 12 age-group. Further, coaches’ evaluations increased again in the post-growth spurt stage, although only significant in the under 15 age-group. Coaches evaluations of player performance appear to vary in accordance with stage of maturity and rate of growth. Practitioners in youth soccer should understand the extent to which maturity status may adversely impact performance and consider this when making talent selection decisions.

  Se ha comprobado y establecido que alrededor del 66% de los componentes del rendimiento y estado del atleta se explican por los factores hereditarios. Dos de los polimorfismos genéticos mas estudiados con relación al rendimiento deportivo en la ultima década, son el ACTN3 R577X y el ACE I/D. El objetivo de este estudio fue resumir las posibles asociaciones de ambos polimorfismos y el rendimiento en jugadores de fútbol, determinando la combinación alélica y genotípica que más destaca en esta población y, además, observar las relaciones de estos a nivel físico y fisiológico. Para la realización de este estudio se llevaron a cabo dos fases, una primera de revisión bibliográfica y una segunda fase de clasificación y análisis de la información. Los estudios evidencian una mayor influencia de los alelos ACE-D y ACTN-R, y de los genotipos ACE-ID y ACTN-RR. Se observó que los sujetos con estas combinaciones tenían mejores rendimientos es pruebas de velocidad y fuerza. Por otro lado, el polimorfismo ACTN3 está directamente relacionado con las lesiones musculares. En conclusión, se pudo observar una relación entre los polimorfismos genéticos y el rendimiento en jugadores de fútbol. Los componentes genéticos se pueden integrar como un nuevo componente dentro de la caracterización del deporte y como una herramienta dentro de un modelo de identificacción y detección de talentos en el fútbol juvenil. Además, los biomarcadores genéticos podrían ser responsables en un futuro, del estudio del riesgo de lesiones para que se optimice mucho más el rendimiento en el fútbol profesional. Abstract. It has been verified and established that around 66% of the components of the athlete's performance and state are explained by hereditary factors. Two of the most studied genetic polymorphisms in relation to sports performance in the last decade are ACTN3 R577X and ACE I/D. The aim of this study was to summarize the possible associations of both polymorphisms and the performance in soccer players, determining the allelic and genotypic combination that stands out the most in this population and, also, to observe their relationships at the physical and physiological level. In order to complete this study, two phases were carried out, the first one of literature review and, the second one which covered the information classification and analysis. The studies show a greater influence of the ACE-D and ACTN-R alleles, and higher presence of the ACE-ID and ACTN-RR genotypes. Subjects with these combinations were found to perform better on speed and strength tests. On the other hand, the ACTN3 polymorphism is directly related to muscle injuries. In conclusion, a relationship between genetic polymorphisms and performance in soccer players could be observed. Genetic components can be integrated as a new component within the characterization of sport and as a tool within a model of identification and detection of talents in youth soccer. In addition, genetic biomarkers could be responsible, in the future, for the study of the risk of injury so that performance in professional soccer is much more optimized.

Identifying the risk of anterior cruciate ligament injury is very important for the careers of elite players. When identifying risk factors, effective, easy, valid, reliable methods applicable to a large number of participants should be used. The purpose of this study was to compare the landing pattern of elite-youth soccer players using the landing error scoring system (LESS) which is a valid and reliable qualitative screening method. 95 volunteer elite-youth soccer players (U19, U17, U16 & U15) between the ages of 14 and 18 participated in this study. Jump-landings were recorded by two camcorders from sagittal and frontal planes. These records were replayed and scored by a trained rater on LESS score sheets. There were statistically significant differences in LESS scores among the soccer age groups (p = 0.00). Post-hoc analysis demonstrated significant differences between U19 and U17 (p = 0.00), U17 and U15 (p = 0.00) and U16 and U15 (p = 0.01) soccer players. The best LESS score was found in U17 players and U15 players had the weakest score. The higher LESS score of the U15 players may be related to the neuromuscular control ability however, more evidence is needed to confirm the potential influence of age categories on LESS scores.

This study investigated the activity profile during small-sided games (SSG) in elite youth soccer players. Internal load (IL) including heart rate (HR) and external load (EL) such as distance covered in different speed-zones (SZ) were collected from forty-eight players of three different teams (U15, U16, U18). The investigation included a total of eighteen 5vs.5 SSGs, each consisting of four 2-minute bouts on a 40x32m pitch during spring season. Total group results (n = 48) showed a reduction in total-distance (p = 0.001; ηp2 = 0.12), high-intensity-running (p = 0.009; ηp2 = 0.09), and low-intensity-running distance (p = 0.028; ηp2 = 0.07) between bouts. Similarly, a reduction in the number of both acceleration-low (p = 0.001; ηp2 = 0.12) and deceleration-high (p = 0.003; ηp2 = 0.11) values was observed. Additionally, time spent in HR-zones 3 and 4 (p≤0.007; ηp2 ≥ 0.10), increased, with a reduction in HR-zone 1 (p = 0.000, ηp2 = 0.25). Age group comparison showed less distance covered in SZ 1 (p≤0.000; ηp2 = 0.56) and greater deceleration-high values (p≤0.038; ηp2 = 0.32) in U15 players compared to other age groups. Further, U15 showed lower values in low-intensity-running compared to U18 (p = 0.038; ηp2 = 0.22). No age-related differences were found for IL and repeated sprint ability (RSA) values. The higher EL in younger age groups should be taken into account when implementing soccer specific SSGs. In addition, HRmean values between 80–85% of HRmax and RSA numbers, which are similar to match-play data, indicate SSGs as an effective training tool to prepare youth soccer athletes for the demands of competition.

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.

Purpose To determine whether training duration is a predisposing factor in potential maladaptations in talent development programmes that promote early specialisation in elite youth soccer. Methods Training times and type of 184 elite soccer players, from the under-9 to under-21 age groups (age 9.4 to 18.4 yrs; stature 1.38 to 1.82 m; body mass 32.2 to 76.2 kg) were recorded. Results Total training time progressively increased between the under-9 (268 ± 25 min/week) and under-14 (477 ± 19 min/week) groups with the majority of training time (96.5 ± 3.9%) consisting of soccer training and matches. Total training time then subsequently reduced from under-14 to under-15 (266 ± 77 min/week) groups, with no differences in training time between under-15 and under-21. Only under-15 to under-21 players completed resistance training; this inclusion coincided with a reduction in soccer training and match play when compared to time spent in these activities for younger groups (73.8 ± 3.2% of total training). Conclusion Data suggest that although the majority of training is focused on technical development, the training duration as a whole is unlikely to contribute to potential maladaptations in talent development programmes in elite youth soccer.
