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   

初中体育“翻转课堂”教学策略分析     

朱小明 《当代体育科技》2020,(12):190-191

翻转课堂是当代教育理念下发展形成的一种新型教学方式,将其合理应用于我国初中体育教学较传统教学方式能够更好地满足当代学生的体育学习要求。但由于该教学理念在我国刚刚进入初期应用阶段,很多细节方面仍有待完善,因此,教师还应进行细致研究,加强新型教育工作实践,制定科学、合理的翻转课堂教学策略,提高初中体育教学工作效率。  相似文献

超高含水原油混合流动及初始沉积特性     

邢晓凯  吕朝旭  刘珈铨 《中国科学院大学学报》2020,37(2):228-233

使用自行设计的实验装置，对超高含水原油的流动特性和初始沉积过程进行探究。系统研究实验温度、混合流速和体积含水率对超高含水原油初始沉积过程的影响，分析不同温度下原油的运动形态和初始沉积方式。初始沉积过程可分为蔓延沉积过程和粘连沉积过程，根据沉积特点和压降曲线的变化趋势将初始沉积过程分为3个阶段：沉积诱导期、快速沉积期和沉积动态平衡期。通过对沉积物碳数分布的分析，得知超高含水原油初始沉积过程中，同时存在剪切剥离作用、胶凝作用和分子扩散作用。实验温度和体积含水率主要通过改变胶凝作用和分子扩散来影响初始沉积过程，混合流速通过改变剪切剥离强度来影响初始沉积过程。  相似文献   

Actions for sociopolitical consciousness in a high school science class: A case study of ninth grade class with predominantly indigenous students     

Bhaskar Upadhyay  Erin Atwood  Baliram Tharu 《科学教学研究杂志》2020,57(7):1119-1147

This case study explores how a group of Grade 9 students engaged in sociopolitical discourses and actions in a science class in a mostly indigenous student school in Nepal. The study used sociopolitical consciousness (SPC) as a framework to document and understand indigenous students’ SPC-oriented science interactions and subsequent social change actions. We used ethnographic methods of data collection over 6 months. The study focused on the actions of 4 girls and 2 boys belonging to the indigenous Tharu group. Data were analyzed using iterative qualitative methods. The study findings show that students are capable of engaging in critical thinking, critical reflecting, and taking actions for social change. Additionally, students are competent to link their experiences with social, structural, and political discrimination to the relevant science content they learn. The study presents four thematic findings related to SPC and science teaching and learning: Fostering social justice awareness in science class, fostering structural understanding of inequities in sickle cell disease, fostering sociopolitical actions for sickle cell disease, and the teacher's activist pedagogy for SPC in science learning. Implications of the study are that culturally relevant pedagogy helps indigenous students to become sociopolitically more aware of the links between science and social change. Adding aspects of critical pedagogies in science teaching could encourage students to become more sociopolitically reflective about science learning.  相似文献   

Investigating Identity: Gender,Overseas Experience,and Japanese Youth     

Erina Ogawa 《Journal of Intercultural Communication Research》2019,48(3):185-202

Identity is prominent in academia, despite it being difficult to define and measure due to its dynamic and multifaceted nature. In Japan, awareness of the make-up of Japanese youth is increasingly crucial as Japan becomes a more internationalized and ageing society. This paper examines, by identity mapping and discriminant analysis, the cultural identities of 94 Japanese youth. While strong Global identities separated the respondents with from without overseas experience, ties to National identities and Relationships were found respectively for males and females. This paper suggests that regarding the study of cultural identities, gender does matter – at least in Japan.  相似文献   

体育产业促进就业:域外经验与本土启示     

朱凯迪  鲍明晓 《武汉体育学院学报》2019,53(11):10-15

就业是民生之本、安国之策。体育产业作为国家积极培育的新经济增长点和支柱性产业，不仅要在促进国民经济发展中有所建树，也应在促民生、稳就业方面积极作为。从文本分析入手，阐释和总结了发达国家体育产业就业的概况和共性经验。研究表明：发达国家体育产业主要通过促进产业成长释放更多就业岗位、响应社会需求扩充热门体育职业、利用赛事关照弱势群体锻造劳力、扶持中小企业提升就业吸纳水平等措施扩大了就业渠道，带动了社会就业。最后以此为关照，启发体育产业促进就业的本土实践新思路。  相似文献   

基于体育课堂观测的小学生身体活动水平及教师教学行为分析     

李兴盈  汪晓赞 《沈阳体育学院学报》2020,(2):27-33

全球儿童青少年的肥胖发病率逐年增高,身体活动不足,每天参加足够量的身体活动是促进其身心健康发展的基本保障。我国儿童青少年面对繁重的学业和大量的家庭作业,课外体育活动参与的时间大大减少,体育课成为了唯一能促使学生参与中等到大强度身体活动的场所。通过SOFIT工具对上海市黄浦区5所小学的217节体育课的学生身体活动水平和教师教学行为进行了观测,分析发现:上海市小学生体育课中的身体活动水平偏低,能够达到50%以上时间进行中等到大强度身体活动(MVPA)的课时比率非常少。教师用于课堂管理和知识讲解的时间过多,且对促进学生进行MVPA的语言干预不够,这些均影响了学生的课内身体活动水平。建议除对学生的活动时间高度重视外,还应该重视学生课内身体活动强度;体育教师应做到“精讲多练”,推动学生积极的参与体育活动;注重开发优质的体育课程。  相似文献
