Body image is closely linked to psychological well-being during adolescence. Physical activity is effective for improving body image disturbance and to date limited body image intervention were undertaken through physical education. Therefore, the aim of this randomized controlled study was to investigate the effects of an 8-week multilateral training on body-image satisfaction and body-size perception. 50 female students, aged 14-15 years, were assigned to experimental group (n = 25) that performed an extracurricular multilateral training program (90 min., 2 days a week) including cardiovascular endurance, agility, dynamic strength, flexibility, and team-building activities, or control group (n = 25). At baseline and after 8-week, anthropometrics and the degree of personal satisfaction towards their body were measured by body weight, Body uneasiness test (BUT) and Contour drawing rating scale (CDRS), respectively. After multilateral training, experimental group showed significant improvements (p < 0.05) in body weight, BUT and CDRS scores. Control group showed no significant changes. Findings suggest that an extracurricular multilateral training program could increase the body image satisfaction and improve the body-size perception in girls. Thus, extracurricular activities such as multilateral training should be considered by physical educators.

Teaching of motor activities in secondary higher school imposes a prescriptive teaching through unidirectional methodological-didactic decisions: teacher directs and the student performs. Improving performance through skills improvement and the structuring of new skills through exercise requires the adoption of a less prescriptive methodology and allowing the student to express himself with greater freedom and awareness to facilitate heuristic learning according to the motor principle by Bernstein of executive variability. Physical education doesn’t have the scientific basis in knowledge as for other theoretical knowledge because the scientific paradigm of corporeality and movement is based on doing and acting. In agreement with the scientific pedagogical community, we ask ourselves about the most appropriate methodology to educate the body with the movement in a habilitative sense, the person through the body for a training of the person (life skills) and strive for the person's well-being through movement (soft skills). This vision seems to be tempered in the documents of physical education up to the first-grade secondary school and seems to change in secondary higher school, when a higher level of education is required. Alongside this prescription, reasonably useful for raising the levels of motor ability of individual services the problem of individual performance in groups arises to achieve the common goal (sports game), where along with significant skill levels, the best and fastest possible decision is also needed. For this necessity, the methodology of the "Teaching games for understanding" comes to the rescue, which contemplates the tactical part together with the enabling one.

The new Global Action Plan on Physical Activity 2018-2030 of the WHO promotes sporting and physical activity as a leading factor for mental health, quality of life and wellness. The document highlights the beneficial effects of regular physical activity and the need to achieve a paradigm shift in supporting and evaluating people regularly, according to the ability and across the life course. A recent systematic review confirms that school health programs promoting active lifestyles among children and adolescents may contribute to the improvement of health-related quality of life. The educational environment plays a key role: physical education is part of all central curriculum frameworks in the EU, and is compulsory in primary and secondary education. The time allocated to physical education in some member states of the EU is insufficient to cover the recommendations of the WHO, so as to assume a marginal role in School Curriculum. This study aims to outline the current state of physical education in European school systems by drawing a comparative framework on topics related to the issue: national and European strategies, large-scale projects, teacher education, status of physical education in national curricula and in extracurricular activity, pupils evaluation and ongoing reform projects. We performed a meta-analysis study analysing national documents of the various member states, international reports of European organization and some international reviews. The results of the study underline strengths and weaknesses of the various national situations to identify the main critical problems and to highlight the potential of sustainable initiatives already validated.

Testing is used to measure the performance and, therefore, to check for the improvements resulting from training activity. More and more frequently, coaches require checks even during the current sporting season to measure the state of the athletes' performance and possibly change their training plans in order to make them more effective. Increasingly testing also has a monitoring function and, therefore, it is expected in the ordinary training activities without changing the annual planning. To do this, it is necessary to provide a type of functional tests for training. The purpose of this study is to monitor the state of efficacy of individual volleyball fundamental of a basic competitive level.

In rhythmic gymnastics, very young athletes undertake a competitive activity and support workloads of four or five hours, almost unthinkable for such small girls, yet to achieve maximum results it is necessary to start at a young age and work hard. The purpose of the study is to study, in different groups of athletes (3-7 years, 8-12 years, 13-18 years) of rhythmic gymnastics, how they face emotionally and physically the physical and emotional workloads and especially if you find physical and mental well-being. The method of the study is qualitative/quantitative and the administration of 10 questions: 5 to identify the physical self-perception and 5 for the emotional one, is done anonymously. The data shows that the self-perception for physical performance is average (positive or negative and put the percentage) and the self-perception for motivation performance is average (positive or negative) and put the percentage. This data is significant for the perceptive state of the athletes to whom it is necessary to refer in order to realistically face the problem. Given the data and their significance, the study must be deepened with a more significant and detailed sample of data.

Evaluation tests represent a fundamental step in the educational path of working with small football players. The method used is of an experimental type whose aim is to analyse the capacity of children in the execution of three fundamental technical aspects of football: Short and Long Passage, Header shot and Shot on Target from a stationary position and in movement. We want to emphasize the importance of training the technical gesture starting from the little ones. In fact, too much tacticism combined with a continuous search for physicality in every area of the field has produced in the last decade an innumerable series of technically poorly trained players. The tests were performed on a sample of 12 children of 10 years old that play championship under-10. The data shows the score from each child during the execution of the various tests from which the total result was obtained by adding the points awarded for each attempt. The average of the high scores for the various tests was 13 for short pass; 27.3 for long pass; 3.6 for the header shot t; 9.6, and 7.75 respectively for stationary and moving shot on goal. The results can be used at the beginning of the activity and when a new group is available to identify the gaps to work on and then they can be repeated in other and different periods of the season to verify how effective the work done up to that point was.

The purpose of this work is to show the execution and the results of a study aimed at identifying and defining the level of the normal people's capacity of adjustment on a wheelchair. This study is based on an hypothesis of a readaptation of a sport's rules of basketball. The new regulation created supposes the contemporary participation of normal people and disabled people and it establishes the use of wheelchairs regardless the physical condition and performance. All of this has been decided to minimize possible physical differences. Consequently, the study was conducted on some young basketball athletes to achieve the intended goal. The chosen athletes are member of an under 15 regional championship. The test administered to them includes some time and precision exercises based on the main fundamentals of basketball, executed on a wheelchair. The test's administration took place in three days to judge the speed of adaptation and learning of using this new tool. The sample group seemed available and open to this first approach with a mobile device used mainly by disabled people, but the results of the study done weren't positive. So, the 30% of the group has provided excellent results and it has been able to perform the test discreetly, improving each time. On the other hand, the remaining 70% observed many problems, worsening their performance in the last drills.

Our earlier reports suggest no dynamic joint stiffness (DJS) inter-limb differences related to footedness. A different approach to our data was used in this study: first define ankle DJS, then look for inter-limb differences and finally correlate them with the subject’s perceived footedness. Methods: 31 subjects (20 females, 11 males) were assessed for ankle DJS during the stance phase of gait, unilateral triple-jump for distance (TSU) and single-leg hopping (Hop). DJS was obtained by linear models at three stance sub-phases (controlled plantar flexion (CPF); controlled dorsiflexion (CDF); power plantar flexion (PPF)). Footedness assessed by the Lateral Preference Inventory (LPI). Results: Paired samples t-test showed statistical inter-limb differences in ankle DJS at PPF on gait (p< 0.01) and Hop (p< 0.05) tasks. No footedness-DJS correlation was found with exception of the TSU PPF (Pearson’s p<0.05). Descriptive analysis shows that in gait, 55% of the subjects maintained the same stiffer ankle between the CPF and the CDF, 45% keep the same stiffer ankle between CDF and PPF, and only 19% keep the same stiffer ankle along all stance. In TSU and Hop, only 48% and 74%, respectively, keep the same stiffer ankle between CDF and PPF. Conclusion: This approach increased our earlier findings of footedness-DJS correlation, but the results are still low. The variability of DJS along the stance sub-phases between tasks needs more attention. Hop task cold be more adequate for footedness assessment due to a more consistent DJS behaviour along the stance.

Hop task cold be more adequate for footedness assessment due to a more consistent DJS behaviour along the stance.","PeriodicalId":288462,"journal":{"name":"Journal of Human Sport and Exercise - 2019 - Spring Conferences of Sports Science","volume":"27 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123428497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the study is to measure the ability to react to a specific stimulus, which in this study can be acoustic or visual. The acquired data allowed us to evaluate two parameters, called: reaction time and action time. The test considers movement in its entirety, trying to identify the mechanisms that allowed the creation of the gesture, even going back to the sensitive phases of motor learning. The various capacities that contribute to the structure of a given motor gesture are considered as inseparable elements of a single project that, in a continuous and non-linear way, influence each other. The method is an experimental research through the recruitment of data with questionnaires and surveys prepared with the Google Forms platform and the evaluation of motor gestures with a technological tool: Optojump Next. The sample is represented by a group of 25 students of the three-year bachelor’s degree in Exercise Science from the University of Salerno, aged between 20 and 27 years. The results of the initial data confirm the impossibility of breaking down the movement into simpler parts in order to understand how it works because it emerges that the movement must be considered in its entirety. The integrated use of quantitative biomechanical and qualitative educational evaluation can be achieved with self-assessment and enabled self-esteem. The results seem to confirm the close relationship between skills possessed and learned in the appropriate stages. In conclusion, the study can be useful to identify performance’s area to be analysed in order to form the motor-sporting educational professional skills most dedicated to evaluation.
