Aim of the study: The main goal of our work was to study and analyse the effect of the first preparatory period in soccer, concerning the different hematological components for young Algerian soccer players, and also to establish recommendations for this population of athletes concerning the medical support and its influence on their performances and the customization of training sessions. Methods: 23 soccer players, those athletes are qualified and well-trained players. They are in good health and belong to a team of professional soccer players in first division (Es/Sétif). They followed a reshaping program for 14 weeks, at least 6 hours a week. All the tests have all been recorded on a special device (at the CHU Saadna Abdenour of Sétif) at the beginning of the season and at the end of the first period of physical training and reshaping session. The subjects had been informed of the study protocol and signed a consent form and all the procedures of the study had been approved in terms of ethics. Results: We observed a significant improvement in terms of statistics on the experimental group.   Article visualizations

Introduction  The practice of high-level sports requires a continuous training. The repeated, intense physical effort the body is submitted to during the training sessions and over the years can lead to metabolic changes. The practice of high-level sports is indeed marked by the repeated, intense training sessions followed by short periods of recovery, which lead to a raise in the spending of energy. This raise favors the activation of new metabolic channels, and thus variation in hormonal numbers and other biochemical parameters. (Galbo H., 2001, pp. 49-57)  As a consequence, permanent medical and personal follow-up is required to maintain, preserve or improve the sportsmen’s health in order to play in optimal health conditions. The physiological, biomechanical, biological, psychological and nutritional support contributes to optimizing the athletes’ efficiency and detecting potential health problems in advance. It requires the intervention of a multidisciplinary team able to help the trainer optimize the training sessions. (Mennetrey N., 2000)  Thus, the biological tests occupy an important position in this medical sports support. In France, for instance, the sportsmen’s biological follow-up care was set up in 1999 as a part of the protection of the sportsmen politics and prevention of doping (Audran M. et al, 2006). In Algeria, the biological follow-up of sportsmen is uncommon, almost nonexistent. Hence the purpose of our work which aims at measuring the hematological assessment of a group of professional soccer players of U17 category; Soccer is the most widely practiced sports in the world, with its 150 federations and its 30 million players registered in clubs, plus the non-registered ones in Africa, South America and Europe.    Since its creation, the demands for the practice of soccer have gone up considerably. The constraints that stem from the practice of that discipline are multifactorial: tactical, technical, athletic, physiological and psychological. The evolution the features of competitive soccer playing led to reconsidering, sometimes radically, some aspects of the training sessions and the players’ overall training program.  Today, professional soccer teams pay more and more attention to the physical training and the athletic dimension of the sports. According to (Wilmore J. H. and Costill D. L., 1998, p. 108), many leaders have understood that the absence of physical training, for a soccer team, can be detrimental at the end of games. But the physiological Aouir Saddam, Bengoua Ali, Houar Abdelatif ANALYSIS OF THE EVOLUTION OF SOME HEMATOLOGICAL PARAMETERS DURING THE FIRST PREPARATORY PERIOD ON YOUNG ALGERIAN SOCCER PLAYERS (U17) European Journal of Physical Education and Sport Science - Volume 3 │ Issue 10 │ 2017                                              130 adaptations that operate through the training of a professional soccer player are divided into central adaptations, that is to say oxygen transport system (heart, lungs and blood) and the peripheral muscular adaptations. That is what allows for an efficient long-term training in terms of energy and muscles throughout the duration of a match (Ancian J., 2008).  The results from the study by (Rahnama et al, 2009) have shown that right before a soccer game, the amount of triglycerides is highly significant compared to the amount measured at the end of it; but is there a link between training (physical training in particular) and the different hematological parameters?  2. Tools and methods  2.1 Regarding ethics This was a non-invasive study with no particular risk. All the consenting subjects have been informed of the aims of the study beforehand. The subjects have been reassured that their privacy and anonymity would be respected and every subject of this study has been informed of the purpose, the protocol and the potential risks of the study and signed a charter of consent (parent’s approval).  2.2 Subjects and samples The population we studied is composed of 23 soccer players from the U17 –under seventeen- category. This sampling was taken at random for all the soccer players consenting to take part in the study. Those who were absent for a blood test phase, those who were on drugs, those who smoked, those who were injured or sick have not been included in the study. The population is rather homogeneous in terms of physical activity and training. Those athletes are considered well-trained subjects, in good health, and they belong to an Algerian professional soccer team of first division (Es/ Sétif). All the players participated in the study. They were all aged (16  ±  0,8  years) in keeping with the F.I.F.A rules; We proceeded to the tests (including blood tests) at the beginning of the 2016-2017 sports season and at the end of the first period of physical preparation and reshaping, that is to say in the form of test-retest (total duration : 14 weeks).  2.3 Methods 2.3.1 Periods of testing The study lasted 14 weeks (from August to December 2016). The gathering of data was divided into two stages, since the general physical training of 14 weeks, made up of a 2-Aouir Saddam, Bengoua Ali, Houar Abdelatif ANALYSIS OF THE EVOLUTION OF SOME HEMATOLOGICAL PARAMETERS DURING THE FIRST PREPARATORY PERIOD ON YOUNG ALGERIAN SOCCER PLAYERS (U17) European Journal of Physical Education and Sport Science - Volume 3 │ Issue 10 │ 2017                                              131 hour training session per day and friendly matches; all the players of the study were measured and received blood tests. CBC (Complete Blood Count) was performed by the same examiners and in the same conditions for everyone. 5ml of venous blood was taken from the left elbow pit, using a special tube. The hematological parameters were immediately determined on a device in a private laboratory and a few samples were examined at the CHU Saadna Abdenour in Sétif.  3.

For the Platelets (290055,55± 13610,95 VS 279111,11±13214,64).   4. Comments  The statistics have shown a relative increase at p<0,05, at a hemoglobin level of 14,02± 0,23 VS 13,82± 0,23) (g/dl). Thus, the hemoglobin level (14,2±0,23  g/dl) is considered higher than the one found on soccer players of third division (12,84  ±  0,37  g/dl) during the same period of the season (Gouthon et al, 2007) and similar to a professional Algerian soccer team of first division (CABatna) ( 44,8±0,6) (Khaled G. et al, 2015 ); Even the difference in biological maturation between the two age groups and the level of potential training, those variations show how the human organism adapts to effort. Relative increase, statistically significant at p<0.05 at the platelet level of 290055,55± 13610,95 VS 279111,11±13214,64)   Hematocrit levels relatively constant (42,0667% ± 0,97 VS 42,46 % ± 0,97) between 34,6 and 52,6% found on Italian professional soccer players (Macovati L. and al, 2003, pp. 570-581) of first division (CABatna)( 44,8±0,6) (Khaled G. and al, 2015 ). On the contrary, our results are superior to 42,3  ± 2,74 %, found on French professional soccer players of first division  (Burn J. F. et al, 2006, pp. 319-350).    5. Conclusion  It is difficult to find precise statistics on the work carried out by sports physicians within an office, within a club, within a federation in the medical data. That is why we exposed this preliminary study to demonstrate the tolerance to training from a hematological point of view, which still belongs to the sector of physiological research   Bibliography  1.
