BackgroundAthletes tend to have better visuo-motor performance than do sedentary individuals. However, several basic visual-function and perceptual parameters remain unexplored to date. In this study, we investigated whether differences exist in visual function, performance, and processing between basketball players and individuals without a sport-involvement background.MethodsA total of 33 healthy men with no visual impairment or pathology were divided into 2 groups, depending on the involvement in sport (semi-professional basketball players and sedentary individuals). We tested their baseline heart-rate variability in the resting position apart from subjective questionnaires to determine their physical fitness level, and we checked their visual function, performance, and processing through an extended battery of optometric tests.ResultsThe 2 groups differed in resting heart-rate variability parameters (p < 0.001), confirming their dissimilarities in regular time practising sports per week. The basketball players showed a closer breakpoint and recovery nearpoint of convergence, a higher fusional-vergence rate, better discriminability halos, and better eye–hand coordination (all p values < 0.05).ConclusionThese results show evidence that athletes, basketball players in this case, exhibit better performance in several visual abilities in comparison to a group of individuals without sporting backgrounds, suggesting an improvement due to the systematic involvement of those skills during basketball practice.  相似文献   

职业足球改革困境：一种非均衡国家治理模式的反思     

周嘉豪 《河北体育学院学报》2020,34(2):1-5

运用文献资料法和逻辑分析法,从非均衡国家治理角度对我国职业足球改革面临的困境进行研究。通过梳理相关文献提出,当前国家治理模式具有非均衡性,存在各主体参与失范、治理权责分配失衡的问题,市场、社会、个人主体话语权较弱、参与性不足,形成了较强的政府依赖路径。对职业足球改革各主体之间的关系进行阐述,认为政府和足协是改革话语权的掌握者和资源的分配者,其他主体参与改革作用较小。指出,尚未明确职业足球的发展动机、足协组织能力与管理效能不足、各主体缺乏有效联系与合作是非均衡国家治理模式的具体表现;政府的非市场手段治理、市场失灵与第三部门失灵、个体意识与自我治理不足是其深层次原因。在此基础上提出相应的发展对策。  相似文献

The relationship between access to pre-school education and the development of social-emotional competencies: Longitudinal evidence from Peru     

《International Journal of Educational Development》2021

We provide evidence of the role pre-school has in the development of social-emotional competencies. We used data from the Young Lives longitudinal study in Peru to test the relationship between attendance to pre-school education with agency and pride at ages 8, 12, and 15, and self-efficacy and self-esteem at ages 12 and 15. We found that attendance to pre-school is related to higher socio-emotional ability, specifically higher scores on indicators of agency and pride. For those that start early (at 3 or 4 years), the relationship with agency persists up to the age of 15 years.  相似文献   

Blended learning in higher education: professional development in a Hong Kong university     

Jennifer Catharine Evans  Hennie Yip  Kannass Chan  Christine Armatas  Ada Tse 《高等教育研究与发展》2020,39(4):643-656

ABSTRACT

Online learning has become a ubiquitous part of the educational landscape and how teachers are supported in developing approaches to teaching online is a fundamental aspect of the students’ learning experience. Based on the implementation of a professional development course on becoming an online teacher offered in a blended learning mode at one university in Hong Kong, this article proposes that offering this type of professional development in a blended mode is very effective in facilitating enhanced usage of the university’s learning management system. In a blended mode, teachers are actively engaged with blended learning and were found to make more extensive use of features/tools in Blackboard after they attended the professional development course. Results support that offering professional development in a blended mode provides teachers with an authentic student perspective, at the same time as they take guided steps in the teacher’s role in blended learning.  相似文献

关于我国引入足球职业裁判制度的思考          下载免费PDF全文

何博芳 《河北体育学院学报》2019,33(4):24-28

职业裁判制度是足球职业化发展到一定阶段的必然产物，其引入将有力提升我国裁判执法水平，助推我国足球事业发展。认为，职业裁判是职业联赛健康发展的关键力量，是足球运动技术发展的客观要求，是提升足球裁判整体水平、统一集中管理的需要。目前，我国的足球裁判存在基数小、水平低、待遇低、环境差等问题。只引入足球职业裁判制度而无配套措施，可能无法解决根本矛盾；目前的国内联赛规模也还无法满足职业裁判发展需求，职业转换难度大及退休保障不足，也阻碍着我国职业足球裁判制度的实施。指出，应加快足球联赛发展，与职业裁判发展互促互进；健全体育裁判法律法规，改革职业裁判组织管理方式；建立健全职业裁判员的薪酬和退休保障体系；注重青少年裁判培养，全面提升在职裁判员业务水平。多管齐下，使足球职业裁判制度发挥更好的效果。  相似文献   

Twenty-four-hour movement behaviours and fundamental movement skills in preschool children: A compositional and isotemporal substitution analysis     

Jéssica Gomes Mota  Cain Craig Truman Clark  Luís Lemos  Cézane Priscilla Reuter  Jorge Augusto Pinto Silva Mota 《Journal of sports sciences》2020,38(18):2071-2079

ABSTRACT

Studies that have analysed the association between the different movement behaviours and fundamental movement skills (FMS) have considered it in an independent manner, disregarding the compositional nature of 24-h movement behaviours (24-h MB). The aim of this study was to investigate the relationship between the 24-h MB and FMS in preschoolers using a compositional data analysis . Two hundred and four preschoolers (4.5 ± 0.8 years old; 101 boys) provided objectively assessed physical activity (PA) and sedentary behaviour (SB) data (Actigraph wGT3X), and FMS (TGMD-2). Sleep duration (SD) was reported by parents. Association of daily composition of movement behaviours with FMS was explored using compositional analysis and isotemporal substitution (R Core Team, 3.6.1). When considered as a 24-h MB composition (PA, SB and SD), adjusted for age, BMI and sex, the composition predicted locomotor (r² = 0.31), object control (r² = 0.19), and total motor score (r² = 0.35), respectively (all P < 0.001). Reallocation of time from light to moderate-to-vigorous PA was associated with greatest positive changes in total motor score. Achieving adequate balance between movement behaviours over the 24-h period, and its relationship with locomotor and object control skills should be considered and further investigated in early childhood.  相似文献
