This study aims at defining the morphological and functional indicators for the selection of footballers according to the three play lines (defence, midfield, attack) for the category of under 18 years old. We will work on finding the differences in these morpho-functional indicators and their relation with the play lines and their requirements. For this, we made the morphological measurements, namely : height, weight, fat-weight, muscle weight, bone weight, and the functional tests, namely : Luc Leger’ Test to measure the maximal oxygen consumption (Vo2max), the retrieval capacity via Ruffier Dickson Test and Vitality Capacity Test V.C, for 10 first level clubs in the West of Algeria; as we selected 18 players from each team with the average of 6 players of each play line (180 players), making a rate of 32% of the original society as a sample. We also used the descriptive and statistical comparative methods among those indicators and each play line in order to know to what extent those morpho-functional variables cause differences among players according to their play lines, while defining those indicators as a reference to be adopted in the players selection process for this age category in order to support the selection process with observation. The results revealed clear differences in the morph-functional indicators among the target category of players according to the differences in their playing lines at the level of the height indicator, as the significance value of selection reached 0.015 which is less than the significance level of the null hypotheses, while we did not find significant differences between the other morphological indicators. Meanwhile, there was a difference in the functional indicator at the level of the retrieval capacity, as the significance value reached 0.011 which is less than the test significance level 0.05; there was no difference at the level the other significances. Thence, the researcher recommends the necessity of consolidating the selection process by the inclusion of observation through the use of some morphological measurements such as height, in addition to functional tests such as the retrieval capacity as important indicators in the players selection process according to the requirements of the play lines for this age category of players, in order to select the best talents that can be beneficial to Algerian football in the future.

Performance Related Parameters Determining the Selection of Youth Players in SoccerIn the current study, a total of 86 soccer’s players with mean age of 14 years drawn from Terengganu soccer academy were tested in performing 10 parameters aiming at determining the performance of those players based on assessing the contribution of each activity and its corresponding significant level. The 10 performance related parameters involved anthropometry (BMI), fitness test (agility, coordination, muscular endurance (push and sit up), power, YoYo level), and football skill test (dribbling with ball, dribbling without ball and juggling). All the parameters testing is carried out based on international standard and performed by well-trained staff. The Pearson correlation analysis was used to achieve the objective in this study. Result shows a positive correlation between the two types of muscular parameters; the power is influenced by BMI and coordination; the specific football tests are highly impacted by the power and agility. The coefficient of determination and the sig...

A Comparison of Some Parameters of Football Players According to the Leagues They Play In2018 •
The purpose of this study was to compare some parameters of football players playing in 3rd League, BAL (Regional Amateur League) and SAL (Super Amateur League) according to the leagues they play in.Body height, body weight, body mass index, age, age of becoming a registered football player, vertical jump, anaerobic power, shuttle run, aerobic capacity (MaxVO2), leg strength, back strength, right-hand grip strength and left-hand grip strength parameters were measured in this study. ANOVA test, which is one of the parametric tests, were applied for the analysis of the data and significance level of p˂0.05 was sought.In conclusion, significant differences among the leagues were found according to height, vertical jump, anaerobic power, shuttle run, aerobic capacity, leg strength and back strength. However, no significant differences were found on body mass index, age, and age of becoming a registered football player, right-hand grip strength and left-hand grip strength parameters.

The study aimed to design a combined test to measure skills performance among the Algerian junior football players based on scientific basis. Adding to the establishment of set of standard grades for skills combined tests to approve the junior players level acting in the Algerian clubs. The research sample was selected among junior players acting in the Algerian clubs of the first and second league. After the initial design of the combined test, it was applied on a sample composed of ten (10) players in order to recognize its validity in an exploratory experience where some adjustments were held on this test then a second exploratory experience was conducted on 17/03/2015 at Berrassi stadium located in Saida on 30 players from MC Saida divided in three equal age groups: U17, U20, U21. The purpose was specify the scientific bases of the test. There were many results , but the most important was that the designed skills test was maily marked by its high grade of truth and reliability ...
In soccer, the relative age effect (RAE) was observed in both adult and young players. The RAE appears to be more pronounced in elite sports, probably by the need to select the best players to compete internationally. This study review: (1) the prevalence of RAE in soccer players, (a) considering competitive level (b) and specific position and (2) association between RAE (a) and anthropometric characteristics, (b) physical fitness components and technical skills. A total of 12 studies met all inclusion criteria for this review. One trial (meta-analysis) was included after the eligibility process. Overall, 77675 young soccer players were analysed. In all studies, significance level of 0.05 was set for the type I error. There is a consensus about the presence of an RAE in men’s soccer, and the percentage of players born in the first quarter in the selection year for professionals is high, with peak values found for elite young athletes, and a large decrease is evident throughout the regional and school representation. The relationship between RAE and the specific position is controversial, according to few studies. It is likely that players born in the first quarter differ in a variety of anthropometric characteristics and physical fitness components compared with peers born in the last quarter. Researchers need to understand the mechanisms by which RAE increase and decrease in order, to reduce and eliminate this social inequality that influence the experiences of athletes, especially in periods of development. Organizational and practical intervention is required.
Background: The purpose of our study was to analyze body composition and spiroergometric data of young (14-15 years) elite level ball sport players. We suggested that three-ball sports (handball, soccer, and basketball) share common performance indicators, as each ball sport is primarily characterized by rapid intermittent movements. Methods: We selected one-hundred and ten, handball (n=30), basketball (n=40) and soccer (n=40) players male and female from local clubs in Hungary. To measure their performance to develop high-quality training programs adequately age was differing from 14 to 15, they represented the elite level of their sports. They participated in performance analysis, the protocol included a body composition analysis and spiroergometric tests. We measured body composition and physiological parameters utilizing an In Body 720 device, and a standard Bruce treadmill protocol. Although we were aware of the limitations of the Bruce protocol in elite athletes, we choose thi...
