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 study aims at comparing each of the mini-games and high-intensity intermittent exercise in order to figure out which of the two methods that most developing the aerobic capabilities (VO2max-VMA), using the experimental approach through proposing two training programs, each program consists of 8 weeks, by two training sessions each week. The size of each share ranged from 90 to 120 minutes, the programs conducted on a sample consisted of 36 players, divided into 18 players from the WABT team and 18 players from the USBT team. It has also been relying on research tools that are in line with the nature and objectives of the study. Physical tests that have been tested validity of the scoping study. They involved 10 players (5 from WABT team, and 5 from the USBT team), without involving the members of the scoping study in the basic study. All of these steps have led to discharging a set of results that have been analyzed and processed statistically to reach at the latter to the following results: • No statistical significance between the two groups in pre- tests. • There are similarities between the two methods in the development of an aerobic capacity (VMA et VO2max). • There is no statistical significance in the post tests between the two groups. After comparing the results of pre and post tests within each group, we concluded the extent of the contribution of each of the two programs in the development of aerobic capacities. All these results prompted us to develop a set of suggestions: • The organization of forums and special days of formation of modern requirements in football means and methods especially from the physical trainers. • Proposing the use of both the high-intensity intermittent exercise way and mini-games during the various stages of the annual planning, especially in the preparation stage and competition stage.

The study aimed to find out the Effectiveness of Physical Training in Improving Offensive Tactics Means Execution in Football, under 19 Category. We have tried through this study to access to effective training program that serves the sports schools and raise private training process level of the offensive in the game of football, because offensive plans and means of implementation make the team overcome any defensive plan, and provide the opportunity for any team to win the game and, thus, win the admiration of the audience. To achieve this, the researcher relied on experimental design per sample represented in the junior category of the team Widad Mostaganem, whose number 10 main players, has been traced in the league average of three matches before and after the implementation of the training program, where the goal of the researcher was to know the effectiveness of the built physical training to improve the means of implementing the offensive play plans of the football players, and check it out, the researcher used the analysis of the games program in data collection according. To confirm that, and in order to verify the results, the researcher used the following statistical methods: (v) of the samples associated with the percentage and made findings that the physical training Built-positive effective in improving the means to carry the offensive play plans of the football players and on the basis of which the researcher recommends the use of physical training Built because of its effectiveness in improving the physical and technically gifted side and even tactical. Key words: efficiency, built-training, playing offensive plans.

Abstract The aim of the paper is to verify the validity and reliability of Scale for measuring tactical and technical competences among football players - assessment of trainers (STTSKT). The research involved 165 players (N = 81 senior and 84 juniors) from seven junior teams and senior Premier League Bosnia and Herzegovina. The average age of the participants is 21.14 ± 4.91; The average age of the junior is 17.23 ± 0.49, while the average age of the senior is 25.15 ± 4.21. The analysis of the main components points to the existence of two factors which in total explain 68.874% of the variance of the specific competence skills of football players. According to the grouping of particles, the first factor was called the attack tactical-technical competence (NTTK); other one are defence tacticaltechnical competences (OTTK). The reliability of the instrument is determined by the coefficient of internal reliability. The obtained number of factors is not in accordance with the obtained factors on the Scale for assessment of tactical and technical competences among football players (STTSK), which was designed as a self-assessment of the competence of football players. Values of alpha reliability coefficients for the full scale and for subscales are high. The results point to the conclusion that the STTSKT scale possesses satisfactory metric characteristics, and that the trainers can use it as a measure of specific competencies among football players. Keywords: competencies, metric characteristics, football players.

Based on the theoretical analysis and the present findings of the research on psychological factors that contribute to the successful implementation, we have designed this research project in order to integrate the knowledge of the Five-Factor Personality Model (McCrae and Costa, 1992), which is the starting point for the Hypothetical model of success in team sports (Mlačić and associates, 2010), and self-efficacy (Bandura, 1986) and the locus of control (Rotter, 1971), which are important determinants of individual characteristics of sportsmen and their contribution to successful sport. Therefore, the aim of this research is to test the contribution of individual psychological features (neuroticism, extraversion, agreeableness, openness to experience, conscientiousness, self-efficiency, locus of control and length of football training as one of the experience traits), in explaining the success of football players. The research involved 165 football players from six football clubs in Bosnia and Herzegovina. For the evaluation of the predictor variables it is used a questionnaire on general data of footballers; The NEO-PI R (Coste and McCrae, 1992) was used for the examination of Five Personality Factors, and the Scale of self-efficacy of footballers was used to examine self-efficiency in football (Šamija and Bosnar, 2010) while the Scale of externality was used to examine the locus of control (Bezinović, 1990). The assessment of the performance of footballers operating through the Scale for the assessment of technical-tactical and social competencies of football players- STTSKT (Šetić, Kolenović-Đapo, Talović, 2017) has conducted 14 trainers. In order to check the contribution of the predictor variables of individual psychological characteristics in predicting the individual success of footballers (STTSKT), we conducted a process of hierarchical multiple regression. According to logical and content characteristics, we have introduced the predicate variables into the two blocks; in the first block there is a personality trait of the Five-Factor model, and in the second block is self-efficacy, locus of control and experience. The individual characteristics of the dimension of the personality of the Five-Factor model explained 6.6% of the STTSKT variance, and after we included the perceived self-efficacy, locus of control and experience in the second step, the model explains 13.3% of the total variance. The model as a whole with both blocks of individual features is significant F (8.136) = 2.597, p <0.01. Of all predictive personality variables, only perceived self-efficacy significantly contributes to predicting success in football (β = 0.251; p <0.05). Key words: psychological traits, football, success

Annotation. For an objective estimation of the load influence orientation in endurance improving kinds of activity the most prospective criterion is the threshold of anaerobic metabolism (TANM).The effectiveness of threshold loads use mainly depends on the accuracy of their determination and control during the training, for this purpose it is necessary to take into account individual peculiarities, the level of sportsman’s readiness and the specificity of ph ysical exercise. Material. This work substantiates noninvasive way of an individual TANM revelation, the method of threshold intensity control is created, the evaluation of the loads effectiveness at the level of TANM is given and optimal volumes of threshold loads, taking into account swimmers’ readiness, are revealed. Research methods: scientific literature analysis and summarizing, for physical activity study and TANM determination swimmers were given step-increasing load at the treadmill, external respiration and gaseous metabolism indices, pulse and lactate were revealed. Results. Noninvasive method of an individual TANM revelation was selected and substantiated on the basis of the results comparison of TANM change according to typical changes (fractures) in the dynamics of different cardiorespiratory indices and lactate concentration in blood during step-increasing load. The effectiveness of threshold load influence depends on the accuracy of its intensity revelation and control and it is possible only on the basis of an individual approach. Threshold intensity control should be fulfilled according to an individual volume of heart rate (HR), calculated at the level of an individual TANM (HRTANM). Individual HRTANM preserves its volume for a long time period irrespective of the level of TANM change. Intensity control according to individual HR TANM provides gradual increase of threshold load intensity with the increase of readiness. Conclusion. Individual anaerobic threshold (TANM), revealed according to lung ventilation, is highly informative index of stayer swimmers’ readiness, which helps to estimate objectively the orientation of the training load influence and determine an optimal volume of threshold loads for endurance development. The effectiveness of threshold load influence depends on the accuracy of its intensity determination and control, which is possible only on the basis of an individual approach. Keywords: swimming, anaerobic threshold, pulse at the level of an anaerobic threshold, load intensity and volume at the level of an anaerobic threshold.
