Coordination pattern of baseball pitching among young pitchers of various ages and velocity levels     

Hsiu-Hui Chen  Chiang Liu  Wen-Wen Yang 《Journal of sports sciences》2016,34(17):1682-1690

This study compared the whole-body movement coordination of pitching among 72 baseball players of various ages and velocity levels. Participants were classified as senior, junior, and little according to their age, with each group comprising 24 players. The velocity levels of the high-velocity (the top eight) and low-velocity (the lowest eight) groups were classified according to their pitching velocity. During pitching, the coordinates of 15 markers attached to the major joints of the whole-body movement system were collected for analysis. Sixteen kinematic parameters were calculated to compare the groups and velocity levels. Principal component analysis (PCA) was conducted to quantify the coordination pattern of pitching movement. The results were as follows: (1) five position and two velocity parameters significantly differed among the age groups, and two position and one velocity parameters significantly differed between the high- and low-velocity groups. (2) The coordination patterns of pitching movement could be described using three components, of which the eigenvalues and contents varied according to age and velocity level. In conclusion, the senior and junior players showed greater elbow angular velocity, whereas the little players exhibited a wider shoulder angle only at the beginning of pitching. The players with high velocity exhibited higher trunk and shoulder rotation velocity. The variations among groups found using PCA and kinematics parameter analyses were consistent.  相似文献   

A comparison of well-peer mentored and non-peer mentored athletes’ perceptions of satisfaction     

Matt D. Hoffmann  Todd M. Loughead 《Journal of sports sciences》2016,34(5):450-458

The purpose of the present study was to compare well-peer mentored and non-peer mentored athletes’ perceptions of satisfaction. A total of 444 intercollegiate athletes (272 well-peer mentored and 172 non-peer mentored) from a variety of sport teams participated in the study. Athletes from both well-peer mentored and non-peer mentored groups reported their satisfaction levels using the Athlete Satisfaction Questionnaire. The results of a MANOVA and follow-up post hoc ANOVAs showed that well-peer mentored athletes were significantly more satisfied than their non-peer mentored counterparts in terms of individual performance, personal dedication, team task contribution, team social contribution, team integration, ethics, ability utilisation and training and instruction. Overall, the findings suggest that athletes who are well-peer mentored by a teammate perceive higher satisfaction levels with various aspects of their athletic experience than athletes who are not peer mentored by a teammate. Given these positive findings, practitioners (i.e., coaches, sport psychology consultants) should inform athletes on the benefits of peer-to-peer mentoring. The practical implications of the results and strategies to promote peer athlete mentoring relationships in sport are highlighted.  相似文献   

安徽R&D投入产出水平的实证分析     

王俊 《中国科技资源导刊 (中国信息导报)》2016,(5):13-18

在国内外的研究基础上,结合安徽特有的基本情况,建立了一套评价安徽省各市R&D投入产出综合水平指 标体系,运用主成分分析和聚类分析,客观的评价了安徽省各地市R&D投入产出水平。评价结果表明,“合芜蚌”试验 区引领带动着全省R&D投入产出水平,“皖江带”城市R&D投入产出水平两极分化严重,而“皖北”地区则有崛起的势 头,从而为各市提升R&D投入产出水平提供参考依据。  相似文献   

中国商业银行竞争力分析     

刘永春 《成都师专学报》2007,26(4):77-80

2001年中国已成功加入世界贸易组织,标志着中国银行业逐步进入全面竞争的时代。国有商业银行不仅面临着国内同业的竞争,更面临国际强手的严峻挑战。＂知己知彼,百战不殆＂,客观地评价国有商业银行的竞争力,发挥所长,弥补所短,以赢得生存与发展空间,对我国银行业的发展和国民经济的发展具有重要意义。本文以实际数据为研究基础,运用主成分分析法,对中国商业银行的竞争力状况进行综合分析,探索提高中国国有商业银行竞争力的有效途径和改革措施。  相似文献   

《家庭暴力防治法》立法问题研究     

邹艳晖 《鸡西大学学报》2007,7(1):57-59

目前,我国家庭暴力问题令人担忧,其中重要原因之一是我国现行法律在规制家庭暴力方面存在不足。应制定专门《家庭暴力防治法》,明确《家庭暴力防治法》在法律体系中的地位,明确家庭暴力举证的特殊要求,明确相关机构干预家庭暴力的责任,明确规定施暴者的法律责任,在立法时并对弱势群体有所倾斜。  相似文献   

Organising and leading systematic quality work in the preschool – preschool managers’ perspectives     

Jan Håkansson 《School Leadership & Management》2016,36(3):292-310

Preschool managers’ responsibility for and leadership of systematic quality work has come to the fore in connection with changes made to the Swedish preschool curriculum. The aim of this study is to contribute to the understanding of preschool managers’ leadership and management of the systematic quality work in Swedish preschools with reference to three specific domains: (i) governance, leadership/management and organisation, (ii) content and methods and (iii) development work and collegiate learning. Using qualitative methods, 18 preschool managers’ perspectives of leading systematic quality work have been analysed in relation to previous research. The results show a tension between linear and interactive forms of governance in the systematic quality work, but also that knowledge gaps among the staff can lead to uncertainties that the preschool manager has to address. At the same time, the results show the diversity of and variation in how children’s development and increased proficiency are documented, while the documentation of the quality of the work focuses on learning environments rather than on teaching and teacher competence. In the study, there are traces of what can be characterised as leadership for learning. This needs to be investigated more closely using other methods in future research.  相似文献
