Analysis of the Influence of Socio-Demographic Variables and Some Nutrition and Lifestyle Habits on Beverage Consumption in the Spanish Population.

Beverages and drinks play a significant role in maintaining the integral health of individuals. The aim of this study is to discover the pattern of beverage consumption in different groups of the Spanish population and to investigate its relationship with other nutritional variables and habits. To achieve the objectives, an observational, descriptive and cross-sectional study was conducted. For data collection, a questionnaire was designed and validated that explored different beverage and food consumption variables as well as socio-demographic and lifestyle variables. The instrument was disseminated, among the Spanish young adult population, through snowball sampling using social networks, collecting a sample of 17,541 valid surveys. Bivariate comparative analyses and correlation analyses were performed, and finally, the principal component analysis (PCA) method was used in order to study the relationships between variables related to drinking and health. The main results show significant differences in the pattern of beverage consumption between the socio-demographic variables of sex, age and educational level, as well as between different areas of Spain, while the PCA model shows the relationship between the consumption of sugar-sweetened beverages with the Healthy Nutrition Index of the population and sport practice. Based on the results of the study, the following conclusions were reached: the beverage consumption pattern of the Spanish population is affected by socio-demographic variables. Healthier drinking habits affect the nutrition and health of the population.

Preventing club bankruptcy: exploring new financial regulation approaches in French football

PurposeThis paper aims to propose an analysis of financial regulation practices, identified thanks to an extensive benchmark carried out in eight European professional sports leagues.Design/methodology/approachBetween 1970 and 2018, 81 French football clubs went bankrupt. The paper proposes an analysis of financial regulation practices in eight European professional sports leagues to enhance the prevention of bankruptcy of French football clubs. Three research questions are addressed: What are the financial and accounting disclosure practices in the main professional leagues? What assessment tools are employed to evaluate the financial risk and budgetary feasibility? What financial support measures exist for clubs and how are insolvency proceedings initiated by clubs? To identify financial regulation practices in professional sport, a selection of leagues was made based on their economic importance, specific regulatory tools used, and their approach to financial difficulties and the handling of insolvency proceedings.FindingsThrough an examination of financial regulation practices in other leagues, three main findings are highlighted: The significance of required financial documents and deadlines varies depending on the competition organizer; some leagues utilize ratio-based assessments rather than relying solely on opinions from financial oversight bodies; certain leagues have established assistance processes for troubled clubs as opposed to punitive measures resulting in administrative regulations.Practical implicationsThis study proposes new financial regulation modalities to prevent the bankruptcy of French football clubs. Firstly, a reform management control is suggested. Secondly, the engagement of stakeholders in bankruptcy prevention is recommended. Lastly, the implementation of a dedicated policy to support clubs facing difficulties is proposed.Originality/valueThe French football federation and the professional league are important actors in the European football. Many bankruptcies are noted in these championships and since the COVID crisis, the financial situation of the clubs has deteriorated, pointing to a strong risk of bankruptcy in the coming years.

Young basketball players have better manual dexterity performance than sportsmen and non-sportsmen of the same age: a cross-sectional study.

Manual dexterity is a key skill in motor development. There are conflicting studies on the influence of sports practice on this skill and on which type of sport trains this ability the most in youth. Manual dexterity is usually assessed with expensive and time-consuming tools not easily available to facilities such as schools or sports clubs. The aim of this study was to assess differences in manual dexterity performance between young basketball players, sportsmen, and non-sportsmen. A further aim was to analyze whether the coin rotation task was a reliable tool for assessing manual dexterity. Based on the characteristics of the sport, we hypothesized that basketball players had better manual dexterity performances. Seventy-eight participants were included in the study and categorized into "basketball", "sports", and "non-sports" groups. Manual dexterity was assessed with the grooved pegboard, the coin rotation task, and the handgrip tests. The basketball group showed better performance in all tests. Significant differences were found between the basketball group and sports group and between the basketball group and non-sport group in the grooved pegboard (p < 0.05) and in the handgrip (p < 0.05) tests. Test-retest reliability of the coin rotation task scores was moderate in the basketball group (ICC2,1 0.63-0.6). Basketball practice could positively influence manual dexterity. The coin rotation task showed an acceptable construct of validity.

The Mediating Role Played by Perceived Motor Competence in the Relationship between Motor Competence and Physical Activity in Spanish Adolescents

The promotion of regular physical activity (PA) is becoming one of the main tools applied in developed countries to address health and obesity problems, particularly in view of the proven benefits of PA on a physical, psychological, and social level. Indeed, childhood and adolescence are crucial periods for an active lifestyle can be established, with the prospect of prolonging it in adulthood. The conceptual model propounded by Stodden provides a theoretical underpinning for the relationship between motor competence (MC) and PA. This study’s objective was to explore the predictive value of motor competence (MC) regarding physical activity (PA), along with the mediating role played by self-perceived motor competence (SPMC) and comparatively perceived motor competence (CPMC), with the purpose of confirming the theoretical model propounded by Stodden, as well as the relationships among variables in our own conceptual model. To this end, we tested a random sample of 925 adolescents (53.6% males; 46.3% females, age 13.75 years, SD = 1.28). Participants completed the Multidimensional Sportcomp Battery to evaluate MC and the Achievement Motivation in Physical Education test (AMPET4) to evaluate their perception of their competence; moreover, to evaluate PA, we used three indicators from the WHO Health Behaviour in Schoolchildren survey in the Spanish version. Our final theoretical model explains 19.9% of the variance of sport practice in boys and 24.2% in girls; moreover, it ascribes an important role to self-perceived motor competence (SPMC) and to comparatively perceived motor competence (CPMC) as mediating variables in the relationship between MC and PA in both sexes. Notably, we found a direct relationship between motor coordination/control tests and PA. Overall, this study underscores the degree to which adolescents’ perceived motor competence affects their actual motor competence.

Sports Practice, Body Image Perception, and Factors Involved in Sporting Activity in Italian Schoolchildren.

Regular physical activity is generally deemed to positively affect health, but studies on children are scarce. Among the kinds of physical activity, sports practice is the most common and easiest to quantify and report by children. This cross-sectional study aimed to compare the two genders and evaluate the association between organized sports practice and body dissatisfaction in a sample of 214 Italian schoolchildren (55.6% males) aged 5 to 12. Body image perception and data on sports practice expectations and facilitators were collected in individual face-to-face interviews; weight and stature were directly measured. Girls tended to be sportier than boys (91.6% of girls vs. 86.3% of boys practiced sports), with an earlier start in sports (5.48 ± 1.47 vs. 5.72 ± 1.38 years) and a greater amount of weekly sports (3.41 ± 2.95 vs. 3.01 ± 2.11 h/week). In both genders, the ideal silhouette was more slender than the feel silhouette, and in girls more than in boys. According to the outcomes of multiple regression models, years of organized sports participation were a significant predictor of the weekly amount of sports in both genders, in addition to the feel weight status minus actual weight status inconsistency score, fun in sports, and parental support only in boys and teacher support only in girls. Children's needs and interests and sports facilitators should be considered to promote an early active lifestyle.

It’s all relative: examining the influence of social identity on sport-based youth development

ABSTRACT Social identity theory provides a framework for understanding how identities tied to sport-based youth development programs facilitate positive youth development (PYD). A common assumption guiding youth sport policy and practice is that the social identities formed around sport-based youth development programs are more salient for youth with limited social support, yet this relationship has not been empirically examined. Using a repeated measures research design, the current study examined the influence of program-based social identity on PYD indicators and tested if this association varied across youth with different levels of social support. Latent profile analysis was employed to identify sub-groups based on key social support domains (i.e. family, peers, coaches). The identified subgroups were then integrated into a repeated measures multivariate analysis of covariance, followed up by univariate and regression analyses. Findings reveal that the impact of program-based social identity on the change in PYD indicators was stronger for youth with limited support from family and peers. However, youth with the strongest support in all domains displayed the strongest indicators of PYD over the program season. The results inform a discussion of theoretical implications related to the role of program-based social identity in PYD and highlight managerial recommendations of sport-based youth development program design and management.

Карьера женщин в спорте в условиях пандемии COVID-19: социально-экономический аспект

The article discusses the features of implementing women's sports career in the context of the coronavirus epidemic. Ways to maintain a career in isolation and options for its development, as well as government initiatives during this period, are analyzed. This includes a comparison of budget expenditures from the start of physical education funding to the post-pandemic period. In addition, types of careers are considered, including the ones typical to the current situation particular, the transformative type of career with a gradual upward movement and subsequent change of activity. This type of career is characterized by a high rate of job advancement (expansion of influence), which can be either gradual or abrupt. The predisposition of women to end their sports career is considered. The author's analysis is based on a sociological study conducted in 2021 in a specially designed questionnaire in Telegram using the survey method, as well as an in-depth interview with a master of sports in ballroom dancing and her career path, which combined several sports, as well as coaching. The current changes in sports practices, including the example of innovations with the help of social networks, which influenced the popularity of a healthy lifestyle are analyzed. The problems of youth sports school students and professional athletes due to the lack of equipment and the complexity of professional training at home are considered. In conclusion, the article examines the consequences not only of the pandemic, but also the ban on the participation of Russian athletes in international competitions, as well as the Olympic Games, and its possible consequences, which will negatively affect the wages of our athletes. In addition to that, there is a number of serious socio-economic problems, including the lack of financial resources for the construction of sports facilities in the regions.

KeepRunning: A MoCap-Based Rapid Test to Prevent Musculoskeletal Running Injuries

The worldwide popularisation of running as a sport and recreational practice has led to a high rate of musculoskeletal injuries, usually caused by a lack of knowledge about the most suitable running technique for each runner. This running technique is determined by a runner’s anthropometric body characteristics, dexterity and skill. Therefore, this study aims to develop a motion capture-based running analysis test on a treadmill called KeepRunning to obtain running patterns rapidly, which will aid coaches and clinicians in assessing changes in running technique considering changes in the study variables. Therefore, a review and proposal of the most representative events and variables of analysis in running was conducted to develop the KeepRunning test. Likewise, the minimal detectable change (MDC) in these variables was obtained using test–retest reliability to demonstrate the reproducibility and viability of the test, as well as the use of MDC as a threshold for future assessments. The test–retest consisted of 32 healthy volunteer athletes with a running training routine of at least 15 km per week repeating the test twice. In each test, clusters of markers were placed on the runners’ body segments using elastic bands and the volunteers’ movements were captured while running on a treadmill. In this study, reproducibility was defined by the intraclass correlation coefficient (ICC) and MDC, obtaining a mean value of ICC = 0.94 ± 0.05 for all variables and MDC = 2.73 ± 1.16° for the angular kinematic variables. The results obtained in the test–retest reveal that the reproducibility of the test was similar or better than that found in the literature. KeepRunning is a running analysis test that provides data from the involved body segments rapidly and easily interpretable. This data allows clinicians and coaches to objectively provide indications for runners to improve their running technique and avoid possible injury. The proposed test can be used in the future with inertial motion capture and other wearable technologies.

What do we currently know about the development of talent? A systematic review in the soccer context

ABSTRACT Talent development is a key topic in sport psychology research and practice. To evaluate what we currently know about the development of talent, this systematic review used a two-dimensional taxonomy to classify contemporary talent research as (1) static or dynamic, and (2) inter- or intraindividual. We focused on empirical studies in the context of soccer, in which most of the talent research so far has been conducted. Following a literature search in July 2022 of Web of Science, Scopus, PsycINFO, and PubMed, 85 empirical studies were included. Most (n = 60) of the studies examined talent development from a static-interindividual perspective. These studies typically explored which factors explained future ability levels in groups of talented players. Only three studies explicitly examined how future ability emerged from interacting talent factors that changed over time for individual players, and were classified accordingly as dynamic-intraindividual. Hence, we conclude that most empirical studies on talent development in soccer lack data on individual temporal processes, which limits our current understanding of how talent develops. To move forward, we recommend that future studies in sports examine how talent development unfolds over time, considering the underlying dynamic and individual nature of this process.

An enhanced label-free proteomics approach for deep-diving into equine plasma proteome, including the discovery of protein biomarkers for strenuous exercise.

Plasma proteins have been a valuable source of biomarkers for clinical uses and for monitoring of the illicit use of prohibited substances or practices in equine sports. We have previously reported the first use of label-free proteomics in profiling equine plasma proteome. This study aimed to refine the method by systematically evaluating various plasma fractionation methods and the use of narrower precursor mass ranges in data-independent acquisition (DIA) mass spectrometry (MS). Tandem fractionations of equine plasma with octanoic acid precipitation followed by solid-phase extraction (SPE) with C4 cartridges provided the largest increase in the number of new proteins identified. The use of two narrow precursor mass ranges of m/z 400-600 and 600-800 in DIA not only identified most proteins detectable by using a single mass range of m/z 350-1500 but also identified ~27% more proteins. The improved method was applied to analyse the plasma proteome of 'postrace' samples which, unlike other samples, had been collected from racehorses soon after racing. Multivariate data analysis has identified upregulation of 14 proteins and downregulation of six proteins in postrace plasma compared with the non-postrace plasma samples. Literature review of these proteins has provided evidence of exercise-induced haemolysis and changes in antioxidant enzyme activities, kinin system, insulin signalling and energy metabolism after strenuous exercise. The improved method has enabled a deeper profiling of the equine plasma proteome and identified the proteins associated with normal physiological changes after racing which are potential confounding factors in the development of a biomarker approach for doping control.

Sports nutrition knowledge, attitude, and practice among male gymnasium users in Jordan

Introduction: Proper nutrition is important for the health and performance of athletes. However, a lack of knowledge might lead to negative attitude and poor dietary practices. This study aimed to determine the levels of nutrition knowledge, attitude, and practice (KAP) among male gymnasium users in Jordan. Methods: A total of 138 male gymnasium users (21.1±2.8 years) from Jordan were recruited. Their height, weight, body mass index, and age were recorded. The KAP-Sports nutrition questionnaire that contains 25 questions regarding knowledge on basic sports nutrition, 12 questions regarding usual food choices and practices, and 20 questions on attitude towards nutrition and sports-enhancing diet were administrated. Descriptive and Pearson correlation analyses were used to analyse the data. Results: Majority of the participants had moderate knowledge on sports nutrition (77.6%), neutral attitude (84.7%), and fair dietary practice (67.4%). Mean score for knowledge, attitude and practice were 18.1±2.6, 58.8±6.2, and 29.7±3.6, respectively. There was significant, weak correlation between knowledge and attitude (r=0.18, p=0.048), as well as between knowledge and practice (r=0.20, p=0.018). Conclusion: Knowledge is important to affect positive attitude and good dietary practices. However, gymnasium users in Jordan did not have a high level of knowledge that could lead to their positive attitude and good dietary practices. Thus, sports nutrition education is recommended to ensure that adequate and correct knowledge are disseminated to gymnasium users.

Thermal profile classification of the back of sportive and sedentary healthy individuals

BackgroundInfrared thermography (IRT) is a non-harmful, risk-free imaging technique and it has application for healthy and pathological population. ObjectiveThe aim of this study is to evaluate the thermographic profiles of the back of sport practitioners from different disciplines and compare it with those of sedentary healthy individuals. MethodThe back of 160 healthy subjects were evaluated, and participants were grouped considering their sport practice: team sport (TS), individual sport (IS), weight training (WT), inactive (I). Three regions of interest were identified to analyze the cervical, thoracic and lumbar temperatures of the back. ResultsThe Multivariate analysis of variance (MANOVA) resulted significant showing statistical differences for the cervical (p < 0.001), dorsal (p = 0.0011), and lumbar areas (p = 0.0366). The Tukey post-hoc test for pairwise comparison showed statistically significant differences between groups. For the cervical area significance was found between the IN and WT group (p = 0.002), the IN and IS group (p < 0.001), IN and TS group (p = 0.020). The dorsal area resulted significant between the IN and WT group (p = 0.007), the IN and IS group (p < 0.001), IN and TS group. The lumbar area showed significant differences only between the IN and WT group and the IN and IS group (p = 0.043). ConclusionThis study demonstrated that inactive individuals manifest a statistically significant higher temperature in the cervical, dorsal and lumbar area of the back compared to sportive individuals.

The Synergistic Effect of Quince Fruit and Probiotics (Lactobacillus and Bifidobacterium) on Reducing Oxidative Stress and Inflammation at the Intestinal Level and Improving Athletic Performance during Endurance Exercise.

Endurance exercise promotes damage at the intestinal level and generates a variety of symptoms related to oxidative stress processes, inflammatory processes, microbiota dysbiosis, and intestinal barrier damage. This study evaluated the effects of quince (Cydonia oblonga Mill.) and probiotics of the genera Lactobacillus and Bifidobacterium on intestinal protection and exercise endurance in an animal swimming model. Phytochemical characterization of the quince fruit demonstrated a total dietary fiber concentration of 0.820 ± 0.70 g/100 g and a fiber-bound phenolic content of 30,218 ± 104 µg/g in the freeze-dried fruit. UPLC-PDA-ESI-QqQ analyses identified a high content of polyphenol, mainly flavanols, hydroxycinnamic acids, hydroxybenzoic acids, flavonols, and, to a lesser extent, dihydrochalcones. The animal model of swimming was performed using C57BL/6 mice. The histological results determined that the consumption of the synbiotic generated intestinal protection and increased antioxidant (catalase and glutathione peroxidase enzymes) and anti-inflammatory (TNF-α and IL-6 and increasing IL-10) activities. An immunohistochemical analysis indicated mitochondrial biogenesis (Tom2) at the muscular level related to the increased swimming performance. These effects correlated mainly with the polyphenol content of the fruit and the effect of the probiotics. Therefore, this combination of quince and probiotics could be an alternative for the generation of a synbiotic product that improves exercise endurance and reduces the effects generated by the practice of high performance sports.

Frequency of consumption of specialty food products by sports university students and violation of the principles of their introduction to the diets

Purpose: estimate actual diet of college basketball players, including frequency of consumption of specialty foods.Materials and methods: 25 male students sports university basketball were examined (average age 20.9 ± 1.8 years). Actual nutrition was studied by the frequency method using the computer program “Analysis of Human Nutritional Status”. Data on the frequency and quantity of consumed specialized food products for the nutrition of athletes (SFP) and biologically active food additives were studied using a questionnaire.Results: the daily energy value of the diet averaged 3205 ± 520 kcal/day, 135 ± 36 g of protein per day, 155 ± 25 g/day of fats and 317 ± 72 g/day of carbohydrates; unoptimal diet structure was revealed — fats predominate from the daily energy value, carbohydrate and protein intake was low. There is a discrepancy between daily food intake (low consumption of fruits, vegetables, bread, fish) and the Order of the Ministry of Sports of the Russian Federation dated October 30, 2015 No. 999 “On requirements approval for ensuring the sports reserves training for sports teams of the Russian Federation” requirements. Basic diet revealed a high average daily content of iron (19 ± 6 mg/day), vitamins A (1057 ± 729 µg ret. equiv) and C (153 ± 101 mg/day). Data on the frequency of taking SPPs and dietary supplements are provided. At the same time, content of some nutrients in them exceeded the upper permissible consumption levels.Conclusion: it is advisable to regularly increase the awareness of coaches and athletes about the rational nutrition principles through the introduction of educational programs into sports practice.

Abstract 159: Long-Term Survival and Neurological Follow-Up of Cardiac Arrest Survivors: Results From the French Multicentric Prospective Cohort the DESAC Study

Background: While short-term prognosis of cardiac arrest (CA) patients has been extensively studied, less is known regarding the mid- and long-term outcome of survivors. Aims: The aim of the DESAC study was to describe mid- and long-term survival and neurological status of CA survivors, and to assess the influence of pre- and intra-hospital therapeutic strategies on these outcomes. Methods: Between Jul 2015 and Oct 2018, patients over 18 years who were discharged alive from intensive care units in Paris and suburbs (France) after a non-traumatic CA were included and interviewed every 6 months during at least 24 months and up to 48 months in this multicentric study. Factors associated with Cerebral Performance Category (CPC) scale at 24 months were assessed with logistic regression, with CPC 1 or 2 level considered as a favorable neurological outcome. Trajectories of CPC were derived by mixed linear model in survivors with at least 3 evaluations. Results: Out of 593 survivors, 525 had a 24 months follow-up (mean age 57.6 +/-15.3, 79% men). CA occurred in public location in 251/525, with an initial shockable rhythm in 392/525. Prognostic factors independently associated with a favorable neurological outcome at 24 months were initial shockable rhythm (OR= 3.53 (1.65; 7.58)) and previous practice of sport (OR= 3.12 (1.20 ; 8.11)), whereas older age (OR per 10 years= 0.52 (0.40; 0.68)) and previous ischemic cardiomyopathy (OR= 0.34 (0.15 ; 0.77)) were poor prognostic factors. Therapeutic hypothermia or coronary procedures were not related to prognosis. Five trajectories of CPC could be derived among the 514 patients. Overall, 64% remained in CPC1, 13% in CPC2, 11% improved from CPC2 to CPC 12% died either early or lately (Figure 1). Conclusions: In this multicentric and prospective study, practice of sport and shockable rhythm were strongly associated with a favorable neurological recovery at 24 months. Furthermore, two thirds of the survivors remained in CPC 1 over time.

Pratiques des entraîneurs sportifs et développement positif des jeunes en milieu défavorisé

Les activités sportives organisées représentent un contexte privilégié pour stimuler le développement positif (DP) des jeunes qui grandissent en milieu défavorisé. Cependant, les retombées positives de ces activités ne sont pas systématiques et dépendent notamment des actions et des paroles des entraîneurs qui les encadrent. On en sait peu sur la manière dont se manifestent concrètement ces pratiques. Cette étude qualitative menée auprès de 12 jeunes issus de milieux défavorisés (9 garçons; Mage = 14,08 ans) vise à répondre à deux questions : 1) Pour chacune des dimensions du DP, quelles sont les retombées des actions et des paroles des entraîneurs sportifs, telles que perçues par les jeunes? et (2) Quelles sont les actions et les paroles des entraîneurs sportifs qui, du point de vue des jeunes, engendrent ces retombées? Les résultats obtenus à partir d’analyses thématiques déductive et inductive suggèrent que les jeunes en milieu défavorisé sont tout à fait susceptibles de se développer positivement et sont en mesure de tirer profit des occasions qui leurs sont proposées, à condition que les entraîneurs valorisent l’école, offrent du soutien scolaire, fournissent des rétroactions constructives et agissent en tant que modèle positif. L’étude confirme également l’importance déjà connue des relations chaleureuses et de la prise en compte de l’opinion des jeunes. Cette étude contribue à approfondir les connaissances au sujet des actions et des paroles qui contribuent au développement positif des jeunes en milieu défavorisé.

High frequency of carpal tunnel syndrome and associated factors: A cross-sectional study in Peruvian workers from agro-export industry.

Carpal tunnel syndrome (CTS) is a peripheral mononeuropathy caused by compression of the median nerve at the wrist and has been reported in workers who perform repetitive movements that involve actions of sustained grasping of vibrating objects. We carried out a cross-sectional analytical study in March 2018 to identify the factors associated with the CTS among workers of agro-export companies in Ica-Peru. CTS confirmation in our study was based on having at least 1 positive screening test (Tinel or Phalen) and a presumptive result of CTS by the Kamath and Stothard Questionnaire. We carried out 4 Poisson regression models to evaluate the factors associated with CTS based on epidemiological and statistical criteria. We enrolled 112 agro-export workers in production (42.0%), packing (35.7%), and administration (22.3%) working areas. The CTS frequency in Peruvian agro-export workers in production, packing, and administrative working area were 78.7%, 45.0%, and 28.0%, respectively. The bivariate analysis found a relationship between the CTS with age, female sex, sports practice, job seniority in the working area (year), and repetitive wrist movements (hours per day). In the multivariate analysis, only job seniority in the working area (year) and repetitive wrist movements maintained their association with CTS. Occupational factors are significantly associated with a high frequency of CTS, such as job seniority in the working area (year) and repetitive wrist movements in agro-export workers. Surveillance programs should be held to prevent, reduce, and monitor workers' health status.

Numerical Evaluation Using the Finite Element Method on Frontal Craniocervical Impact Directed at Intervertebral Disc Wear

Traumatic cervical pathology is an injury that emerges due to trauma or being subjected to constant impact loading, affecting the ligaments, muscles, bones, and spinal cord. In contact sports (the practice of American football, karate, boxing, and motor sports, among others), the reporting of this type of injury is very common. Therefore, it is imperative to have preventive measures so players do not suffer from such injuries, since bad practices or accidents can put their lives at risk. This research evaluated cervical and skull biomechanical responses during a frontal impact, taking into consideration injury caused by wear on the intervertebral disc. Intervertebral disc wear is a degenerative condition that affects human mobility; it is common in people who practice contact sports and it can influence the response of the cervical system to an impact load. The main objective of this work is to evaluate the effects caused by impact loading and strains generated throughout the bone structure (composed of the skull and the cervical spine). The numerical evaluation was developed using the finite element method and the construction of the biomodel from computational axial tomography. In addition, the numerical simulation allowed us to observe how the intervertebral disc’s wear affected the cervical region’s biomechanical response. In addition, a comparison could be made between a healthy system and a disc that had suffered wear. Finally, the analysis provided information valuable to understanding how an impact, force-related injury can be affected and enabled us to propose better physiotherapeutic procedures.

THE ROLE OF THE PHYSICAL EDUCATION CLASS IN THE ADAPTATION AND SOCIAL INTEGRATION OF PUPILS

Sports practice is a means of socializing the individual and providing him with extensive experiences and skills that enable him to adapt and integrate with his society. Sports practice has an effective role in creating a state of satisfaction and achieving the individual’s desire and tendency to practice what he likes and prefers from games because of the activities and sporting events they contain. It is also considered an important educational mediator in the socialization of adolescents. In line with this problem, this contribution represents a field investigation that was conducted in Tlemcen town, specifically in the secondary school of the Brothers Benazza in the municipality of Souani, with a sample of students of both sexes amounting to 25 cases. On methodological plan, our research uses semi-directive interview and leans principally on a qualitative approach.
