Testing is one of the important tasks in any multi-step sport programme. In most ball games, coaches assess motor, physical and technical skills on a regular basis in early stages of talent identification in order to further athletes’ development. The purpose of the study was to investigate anthropometric variables and vertical jump heights as a free throw effectiveness predictor in water-polo players of different age groups. Two hundred and thirty-six young (10–18 years) male water-polo players partitioned into three age groups underwent anthropometric variables’ measures and squat- and countermovement-jump tests, and performed water-polo free throws. Anthropometric variables, vertical jump heights and throw speed – as a proxy for free throw effectiveness – resulted different over age groups. Particularly, throw speed changed from 9.28 to 13.70 m · s^?1 (+48%) from younger to older players. A multiple-regression model indicated that body height, squat-jump height and throw time together explain 52% of variance of throw speed. In conclusion, tall height, high lower limb power and throwing quickness appeared to be relevant determinants for effective free throws. Such indications can help coaches during talent identification and development processes, even by means of novel training strategies. Further research is needed over different maturity statuses.  相似文献   

Development and validation of the Perceived Game-Specific Soccer Competence Scale

ABSTRACT

The objective of this study was to create a valid, self-reported, game-specific soccer competence scale. A structural model of perceived competence, performance measures and motivation was tested as the basis for the scale. A total of 1321 soccer players (261 females, 1060 males) ranging from 12 to 15 years (13.4 ± 1.0 years) participated in the study. They completed the Perceived Game-Specific Soccer Competence Scale (PGSSCS), self-assessments of tactical skills and motivation, as well as technical and speed and agility tests. Results of factor analyses, tests of internal consistency and correlations between PGSSCS subscales, performance measures and motivation supported the reliability and validity of the PGSSCS. The scale can be considered a suitable instrument to assess perceived game-specific competence among young soccer players.  相似文献   

Development of perceived competence,tactical skills,motivation, technical skills,and speed and agility in young soccer players

ABSTRACT

The objective of this 1-year, longitudinal study was to examine the development of perceived competence, tactical skills, motivation, technical skills, and speed and agility characteristics of young Finnish soccer players. We also examined associations between latent growth models of perceived competence and other recorded variables. Participants were 288 competitive male soccer players ranging from 12 to 14 years (12.7 ± 0.6) from 16 soccer clubs. Players completed the self-assessments of perceived competence, tactical skills, and motivation, and participated in technical, and speed and agility tests. Results of this study showed that players’ levels of perceived competence, tactical skills, motivation, technical skills, and speed and agility characteristics remained relatively high and stable across the period of 1 year. Positive relationships were found between these levels and changes in perceived competence and motivation, and levels of perceived competence and speed and agility characteristics. Together these results illustrate the multi-dimensional nature of talent development processes in soccer. Moreover, it seems crucial in coaching to support the development of perceived competence and motivation in young soccer players and that it might be even more important in later maturing players.  相似文献

Teachers in school sports: between the fields of education and sport?     

Magnus Ferry 《Sport, Education and Society》2016,21(6):907-923

According to the cultural sociologist Pierre Bourdieu, gaining access to a social space or a position within a social space requires a specific capital. For teachers, this is normally indicated by a valid teaching certificate with relevant subject knowledge. However, when no qualified teachers are available, which is the case for the subject of school sports in Sweden, other assets gain recognition. Drawing on Bourdieu's conceptual framework, this paper examined the conditions for school sports in Sweden, and based on questionnaires answered by 109 teachers, explored the competencies, education and backgrounds teachers in upper secondary school sports possess. The paper address the question: what valuable resources are required to become a teacher of school sports and gain recognition as symbolic capital? The results show that while school sports in Sweden are carried out through a school subject and thus regulated by the government, it is influenced by both the fields of education and sport. Furthermore, the questionnaire results show that a majority of the teachers are employed as coaches instead of teachers and that less than half of them (45%) have a teacher education background, while 95% have a coaching education background. However, the results also show that teachers assessed their competencies for teaching school sports as high, especially with regard to competencies in specific sport skills. In conclusion, this paper shows how coaching education and experience in competitive sports are an important resource required to become a teacher in school sports and is thus recognized as symbolic capital. Therefore, school sports cannot be viewed as a legitimate part of the field of education but can be viewed as a part of the field of sport.  相似文献   

德国职业教育对工业4.0的回应: 提升劳动者数字能力     

陈莹 《比较教育研究》2019,41(6):90-97

在工业4.0时代,劳动者驾驭智能化新型工业生产模式的数字能力成为实现国家发展策略的关键因素。因此,德国政府将劳动者数字能力培养提高到了战略层面并出台系列措施进行战略部署,包括:开展大型研究项目对工业4.0背景下数字能力概念的维度和内容进行深入解读;在分析实践困境的基础上,对企业、跨企业培训中心和职业学校各大办学主体分别给予扶持;参照工业4.0带来的全新任务领域对各个职业教育专业标准进行修订等。劳动者数字能力培养体现了在"人与机器"关系中以人为本的价值取向,代表了工业4.0背景下德国职业教育的改革重点和发展趋势,同时也凸显了德国政府顶层设计的作用。  相似文献
