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.

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. Keywords: morpho-functional indicators, player’s selection, play lines 1. Introduction Modern scientific research in the domain of sport training in general and football in particular, is interested in giving data and scientific truths in order to promote the quality of sport results and achievements existing in all the competitions and championships, as the training and form of the athletes has got an important share of researchers and specialists’ interest in order to know the main criteria of the athlete’s body, including morphological criteria and anthropometrical measurements that are meant to enable him to excel among his peers and contribute in a direct way in making him successful in his specialty or in his play centre, and thus to make him more effective in the team. That is why research in defining these specific criteria varied, (Bengoua Ali, 2004) mentioned that football is one of the sports that attract the majority of spectators, and that it is worth the competition among its coaches and interested people to get benefit from the tests and measurements at all levels, such as skill and physiological measurements of players, while making physical measurement in order to select the most talented youngsters, add to that the fact that football is one of those mass games which attract spectators throughout the world in the different international competitions and championships, and that is why it could get as much interest of science and research in order to arrive to suggestions and recommendations that lead to better achievements, and this requires specific criteria either at the morphological level or the functional and physical one which are related to the skill side and which is not European Journal of Physical Education and Sport Science - Volume 3 │ Issue 10 │ 2017 143 Chachou Seddaoui, Houar Abdelatif, Hadjar Mohamed Kherfane DEFINING THE MORPHO-FUNCTIONAL INDICATORS FOR THE SELECTION OF FOOTBALLERS ACCORDING TO THEIR PLAY LINES enough for excelling or achieving the highest levels, (Samir Chiban, 2010) confirms that there is a difference in the morphological structure between the elite athlete and the championship’s one due to the interest in skills as well as the physical aspects while neglecting puberty and its influence on the selection process. Morphological requirements are also considered to be the requirements of modern football, as the distinction within one team is dictated by the quality of the playing lines and centres which are: the goalkeeper, the centre of defense, the midfield and the attack. (Houar Abdelatif, 2015) showed that there were statistically significant differences between play lines and body measurements such as body weight, height, body mass index, and maximum oxygen consumption. This is an indication that the indicators for body building and formation and all that is related to measurements of dimensions and characteristics of body shape in general, has a direct relationship and positively affects the sport results through outstanding performance. Besides, the functional and physiological capabilities have an important role, as they took an important part of scientific research due to the strong relationship between high performance and readiness of the physiological functions and their efficiency, as there are individual differences between players in this aspect on one hand and the requirements of play centres of physical effort on the other. (Akbobi Habib, 2017) says that experience is not always enough for the coach, as he is in dire need of precise parameters or indicators of physical activity, tactic, physical condition and even biological aspect of the players for the play centres. It is also possible to predict on the basis of the capabilities and functional capabilities of the player such as the efficiency of the periodic and respiratory capabilities of the retrieval capabilities in the selection process at the high level, and this accelerates the achievement of success with economy in time, effort and money and this is consistent with the study that we are conducting, since the selection process by observation is not enough scientifically, and this fact led us to search other determinants which are more precise and objective to be used in the selection process in the under 18 years old category of footballers, as the study is considered to be an important and scientific dimension that is meant to support the observation-based selection process at the higher level in the national championship through the use of the database as a scientific reference.
