THE IMPACT DIMENSIONAL OF DELIMITERS ON TESTING AND TRAINING DUELS DRIBBLING IN YOUNG SOCCER (UNDER 15 YEAR)

The delimiters are the most important tools, widely used in training and tests soccer, because they embodies the dimensions of the surface and the role of defender in major of the exercises for Soccer. That literature review 90% of soccer books use the smallest delimiters (plate) and 100% of our young soccer Algerians coaches (under 15 year) composed their sessions. from that the objective of our study focuses on the different forms and volumes of these last lend, based on these differences our hypothesis confirms that they affected the information (indicators from the external environment) and qualities coordinators during the change of direction (obstruction of the upper body player). Our experience is based on a practical protocol of Vankersschaver Jacques1982 from his study entitled "Role of Visual Index and Cognitive Process in the Acquisition of a Gesture Football Technique”. Were we have introducing the different kinds of delimiters (fig1) and the inactive player to determine the most type of delimiter appropriate to evaluate and train duels with ball in young soccer. Were our finding confirmed: (1) The mannequin is the most delimiter appropriate for testing and progress in duels soccer. (2) The progress in training duels requires the smallest (familiar with the gest) arrive at the mannequin to perform with the gest (1vs1). (3) The objective of duels requires the involvement of the commitment of peripheral vision for information and central vision to master the ball. From that, the best dribbler is the player who lifts his head when he moves with the ball

The researcher followed the experimental method because of the relevance of the research issue. The study used a sample of the Mostaganem team under 17 years old consisting of 35 players; they were divided into two samples, the first sample consisted of (13) players a normal training program was applied with them , the second experimental group consisted of (13) players the training program applied offered by the researcher. Finally, the researcher suggests that the proposed program positively influence the development of speed-strength and some technical skills. A set of physical and skill tests were applied and after getting the results of the pre and post measurements and the statically processing of results, the researchers have concluded that integrated exercises (physical- skill) has a major impact in developing the speed-strength and some basic skills of football players under 17 years old.  Article visualizations

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

INFLUENCE TECHNIQUE VS IDEAL MODEL ON CREDIBILITY THEORY DISTRIBUTIONS RATIOS: A CASE STUDY OF TRIPLE JUMP

The objective of this study is to describe and compare the techniques used by elite triple jumpers in the world to determine the impact of the modality distribution ratios in achieving results. Our subjects were the 2009-2011 global elite’s finalists with five (5) Algerian amateur athletes. In the absence of technological methods in Algeria, our study explores the reports (IAAF): 1. To describe the phase distribution of the practice model between our world champions (2009 and 2011) 2. To compare the credibility theory of distributions ratio achievement with the modality dominant techniques practiced by champions (2009 and 2011). 3. To answer this question: can we consider the phase difference ratios as a bad distribution error in the technical ideal? As a result, we chose the analysis of variance and the correlation of relative distances obtained from each phase of the official distance achieved by the athlete. For the study statistics, our used data is based on the "t" independent method compared to the impact phase distributions (hop, step, and jump) charged with the results achieved in the test. However, our goal for this research is: • Using biomechanics to determine errors and integrate the modern scientific methods in monitoring the athletic program. • To allow our elites and their coaches to examine the impact of modality distribution ratios in achieving results in order to choose the good combined efforts and the selected template model practiced to improve the best performance in training and competition

Determining the standard levels of some morphological and physiological requirements as an indicator for the selection of defenders in the Algerian football U19

This study aims to identify the most important morpho-functional measures and determinants through standards and tests and their relationship with the selection of football players under the age of 19 in the defensive position, so that coaches can realize the true value throughthis study and correct the previous mistakes based on observation and matches and their distance from the side for the selection of players whose results are certain and guaranteed. We first assumed that the level of morphological criteria of defensive players is characterized by an average level, on the other hand, that the level of physiological criteria is characterized by an average level, and for the purposes of investigation of the hypotheses, we have selected a sample composed of 90 defenders from different defensive positions representing 10 clubs active at the level of the Algerian first and second division (class under 19 years old) for football for the 2022/2023 sports season. They were chosen deliberately, and for this we used the descriptive approach, through which we collected data using the physical measurements necessary to determine morphological indicators (height, weight, mass index, musculoskeletal system and physiological tests, then statistical processing of the data). The research yielded the following results: The levels of defensive players (axial - right and left wingers) in measurement of height, weight, muscle mass index, shows the levels in favor of the good level and the average level compared to the physiological criteria. That is why we have recommended the use of physical measurements and physico- physiological tests during the selection and even in the orientation according to the play centers, in particular the lengths and the components of the body style and the preparation of training programs based on scientific bases and paying attention to young groups of young people at all levels

Development of some aerobic and anaerobic indicators in under-21 footballers using hypoxic training mask during the physical preparation period

This study aims to identify the effect of a training program using the hypoxic training mask on certain aerobic capacities (VMA, VO2max), on the effectiveness of the repetition rate (RSA), and on the explosive power of football players. The sample was deliberately selected and included 20 football players under the age of 21 from the Tiaret youth team, which plays in the second professional division. A total of 10 players were assigned to a control group and the other 10 players to an experimental group. The research used a series of physical tests that included VMA/VO2max intermittent yo-yo tests and RSA repetition rate efficiency tests, in addition to the explosive force tests using the MYOTEST device. The same training program was applied to the experimental and control groups, with the first one using the mask for 8 weeks. The study concluded that there are statistically significant differences in the pre- and post-measurement of the experimental and control groups in the measurement of aerobic and anaerobic capacities in favor of the experimental group, who wears the hypoxic mask. This underlines the importance of using modern technological means in the process of physical preparation and raising the level and efficiency of the players to reach the highest levels of achievement

EFFECTS CLASS OBESE I, II, III HOUSEWIFES ON THE SYSTEM CARDIO-RESPIRATORY CAPACITY

The goals of this study are to find ways to determine the risks cardiovascular and respiratory capacity in class obese I, II, III housewife based on them adaptation to effort. Since obesity has reached epidemic as levels in cholesterol fractions, and triglyceride as risk factors of metabolic health track into adulthood which confirmed that the body physical fitness has a significant modifying effect on other risk factors as cardiovascular disease. Our role is to expose the impact of the class obesity on the level fitness to health. In order to achieve this objective, in one hand we have chosen the Ruffier-Dickson index and Maximum Heart Rate which are safe bet in the sports medical baseline budget. On the other hand, our sample was selected by intentional method represented by 30 women; their homogeneity was calculate based on age ≤ 27, BMI≥ 35,77 and Questionnaire Physical Activity Rating (PA-R) from Non-Exercise Data and Non-Exercise Fitness Test. Our entire sample selected that prefer staying at home. In order to classify our sample, we have selected the BMI classification system for adults Programs and Health Survey for England which classed our sample in three categories obesity I, II and III. For the statistical processing, we based on Mean, SD, Correlation Paired Samples, Anova and LSD to determine the effect of overweight on the both cardio-respiratory capacity failure between the three classes in active exercise as our safe test. Based on the analyses statistics we confirm: - is a strong positive relationship between the increase BMI and the level of the variables selected in this study; - Class Body Composition reveals the weaker skeletal muscle function, decreases cardiorespiratory capacity and the low fitness aerobics ability; - Class Body Composition predict the weaken cardio respiratory capacity related to the combination of “respiratory rate and airway narrowing” which lead to fatigue of the muscles of ventilation.  Article visualizations
