ANALYSIS OF THE EVOLUTION OF SOME HEMATOLOGICAL PARAMETERS DURING THE FIRST PREPARATORY PERIOD ON YOUNG ALGERIAN SOCCER PLAYERS (U17)

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

DEFINING THE MORPHO-FUNCTIONAL INDICATORS FOR THE SELECTION OF FOOTBALLERS ACCORDING TO THEIR PLAY LINES

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

THE EVALUATION OF THE AEROBIC AND ANAEROBIC CAPACITIES AS A SETTER FOR DIGITAL ACHIEVEMENT AND AS AN INDEX FOR SELECTING AND GUIDING THE BEGINNER'S ATHLETICS

The research aims to the physiological side from the athletics beginner’s training according to scientific basics and principles which is must include the measurements and testing operations because of its selection processes importance and to determine the results, evaluate the current level of the players, and how do they should be in future. Through the capacity assessment and adopted to determine the level of digital achievement and takes it as an index to guide athletics beginners for its various events and this is what we sought to search in it in athletics beginners category (16-17). For Algerian west clubs (210 athlete by 33.92% from the origin community) relying on some special field measurements and down to highlight the connectivity relations and comparison of the aerobic and anaerobic capacities with the digital achievement for the various practiced events and to reach the goals of the research we used the descriptive method with a survey style. After testing and collecting and processing the information, it was reached to detect the level of the aerobic and anaerobic capacities for the beginners, we found the relationship of these capacities with the digital achievement in various practiced events besides the existence of differences between the beginners in some capacities because of the different events within the per class (jogging, jumping, throwing).  Article visualizations

Effects of Quarantine Due to the COVID-19 on Sleep Duration and Quality in Algerians

This study tests the impact of COVID-19 on sleep of Algerian population before and during the COVID-19 quarantine by an estimated online survey, adapted from the PSQI Italian version. Including 1210 participants (age between 18-60 years old). The statistical analysis was carried out using SPSS version 22.0 software. Our results showed a significant change in sleeping quality during quarantine, the sleep timing markedly changed, we also noticed additional use of sleeping medications. Algerian scientists recommend to build public awareness and to provide necessary information regarding Algerian sleep quality, especially for Algerian adults
