太极拳对非体育专业女大学生身心健康影响的实验研究

文章以商丘师范学院的30名非体育专业的健康女大学生(年龄为20.12 1.98)为研究对象,进行太极拳运动对人体身心健康影响的实验研究。结果显示:经过6个月的实验,实验前后受试者在生理机能、身体素质和心理健康等方面都有显著差异(P<0.05),并有一定的减肥效果。太极拳是一项较好的全民健身手段,应予大力普及、推广。     

高中女生体育与健康课教学刍议

高中女生对体育与健康课缺乏学习的积极性和主动性,学习热情不高、兴趣贫乏,普遍存在着"怕动"的念头。经常要教师赶着、逼着去练习和活动,处于一种消极、被动的心理状态,特别是对于那些技术性较强、运动负荷较大的项目有着畏惧情绪,缺乏自信心。文章对这一现状进行了分析研究,并提出一系列对策,以推动高中女生全面健康的发展。     

我国优秀女排队员移动拦网技术动作解析

1前言近年来世界排球大赛的实践表明，拦网已从单一的防守技术转变为攻防兼备的制胜技术之一。拦网水平的高低不仅直接影响比赛的胜负，而且也是衡量一支球队技战术水平的重要标志之一，因此，备受国内外教练员和科研工作者的关注。长期以来，有关拦网技术的研究，仅限于现场统     

Ali–Frazier 1: Black Gladiators,White Promoters,and the Economics of Big-Time Boxing

Abstract

The March 1971 heavyweight championship bout between undefeated black boxers Muhammad Ali and Joe Frazier elicited numerous responses. Ali, because of his brash persona, refusal to be drafted into the Vietnam War, and outspoken criticisms of white racism, had become a potent symbol of 1960s rebellion and Black Power. Frazier, by claiming the heavyweight championship while Ali was banished, cozying up to white politicians, and refusing to criticize the US government, made himself a worthy foil for Ali’s politics. But as the rhetoric surrounding the fight intensified, regarding black masculinity, patriotism, and community pride, one key aspect of the fight opened up debates in a surprising realm: the economics of black athletes and the possibilities and limitations of black capitalism. In an era when black capitalist programmes emerged nationwide, and when African-American athletes took on more vocal roles as community activists, the battles over the bout’s financial promotion became intense. While the boxers took home an unprecedented $2.5 million each for their participation, total revenues reached nearly $30 million. Discussions of the fight’s payout shed light on a wide range of economic issues facing the black community, and some of the unresolved issues in the quest for civil rights.     

Guideposts and Roadblocks to the Career-Long Scholarly Engagement of Physical Education Teacher Education Faculty

Purpose: Scholarship is essential for the growth and development of the physical education field. Over time, scholarship expectations have changed, forcing faculty members to alter time spent for research, teaching, and service. Social-cognitive career theory (SCCT) presents a model for understanding performance and persistence in an occupational environment. The interconnected aspects of SCCT have different emphasis related to self-efficacy, outcome expectations, or personal goals pursuit. This study explored physical education teacher education (PETE) faculty members’ continuing engagement in scholarly activity through SCCT. Method: Data collection included interviews with 9 senior PETE faculty members who met the criteria for “productive scholars over time.” Curriculum vitae were collected to verify productivity. Results: Data analysis revealed guidepost themes that included collaborating, finding balance, defining a research process, and maintaining a strong work ethic. Roadblocks encountered included other obligations and lack of support for research. Conclusions: Participants demonstrated strong self-efficacy; held high, positive expectations for success; and set very specific, clear, and deliberate goals. Participant behavior was moderated by their personal attributes (capacity to build relationships, set goals, and maintain interest and passion) and was tempered by the environments in which they worked. Fostering similar behaviors has the potential to guide future and current PETE faculty members in creating supportive and encouraging atmospheres for sustained productivity. The lack of literature relating to this topic warrants the need for more research exploring the influential factors and benefits gained from sustained scholarly productivity over time for PETE faculty members.     

我国优秀女子铁饼选手“人-饼”速度指标的运动学分析

摘 要：采用文献资料法、专家访谈法、三维高速影像解析法和数理统计法,对现阶段我国优秀女子铁饼运动员旋转技术的速度特征进行分析,得出以下结论：重心和铁饼的分速度大小及比例对运动员技术风格的形成有重要影响;“人-饼”系统在腾空和过渡阶段是最复杂和最难控制的,这两个阶段的系统变化对形成最佳技术具有决定性作用;我国运动员第二和第三旋转轴的速度传递稳定,第二轴髋关节和膝关节速度决定着位移的方式,第三轴肩关节速度同铁饼的时空特征有较大相关性。     

Surviving Being Dark: A Pedagogy of the Sacred for Survival in a Divided Society

Abstract

Historically, Blacks have out of necessity prioritized survival in educating their younger generations for existence in the racially hostile and divided context of the U.S. This education and religious education has occurred formally and informally in homes, schools, community organizations, and in congregations. This paper examines three aspects of survival: survival and emancipatory education, survival and justice, and survival with emerging Black generations. Three examples will be offered that highlight each aspect of survival. The examples will demonstrate how education generally and religious education in particular have undergirded pedagogies of the sacred for the survival of Black life.
