Dispositions of elite-level Australian rugby coaches towards game sense: characteristics of their coaching habitus

Bourdieu's analytic concept of habitus has provided a valuable means of theorising coach development but is yet to be operationalised in empirical research. This article redresses this oversight by drawing on a larger study that inquired into how the ‘coaching habitus’ of elite-level Australian and New Zealand rugby coaches structured their interpretation and use of the Game Sense approach to coaching to illustrate how habitus can be operationalised. It focuses on the identification of characteristics of the individual coaching habitus of four elite-level Australian rugby coaches and how they shape their interpretation and use of Game Sense. Drawing on suggestions made by Lau, we identify the characteristics of four individual ‘coaching habitus’ by examining their views on: (1) the characteristics of good coaches; (2) characteristics of great rugby players and how to develop them; and (3) their dispositions towards innovation in coaching.     

Hamstring rate of torque development is more affected than maximal voluntary contraction after a professional soccer match

Abstract

Match-induced fatigue of knee muscle strength and agonist-antagonist strength-ratios may affect both performance and risk of injury in soccer players. Once explosive tasks are imperative in soccer as well as hamstring strain injuries occur during high-velocity moments, rapid force capacity of this muscle group is especially important. This study evaluated the effect of match-induced fatigue on knee muscle strength and strength-ratio parameters after a single professional soccer match. Male professional soccer players (n?=?16; 24.2?±?3.9 years) were tested before and after a soccer match (56.2?±?22.6?min of playing) for knee flexors (hamstring) and extensors (quadriceps) isometric peak torque (MVC) and rate of torque development (RTD) – as well as the hamstring-to-quadriceps ratio (H:Q) – at 30° of knee flexion. Knee injuries often occur at this joint angle, which is common in sprinting, pivoting, sidecutting, and jumping. Match-induced fatigue caused a left shift in the knee extensors torque-time curve with no significant change in both early (i.e. 0–50?ms) and late (i.e. 0–200?ms) RTD, and a right shift in the knee flexors torque-time curve with a decrease in early RTD (～16%, p?=?.029) and late RTD (～11%, p?=?.011). Knee extensors and knee flexors peak torque remained unchanged (p?>?.05). Early RTD H:Q decreased by～24% (p?=?.027), while late RTD H:Q and MVC H:Q remained unchanged (p?>?.05). In conclusion, match-induced fatigue impaired the ability to rapidly produce force at an angle where injuries are most susceptible to occur. Important information is missed if only the traditional H:Q is considered.     

我国竞技体育发展中政府职能运行的思考

为深化对当前我国竞技体育发展中政府职能运行的理论认识,运用文献资料法、逻辑分析法,从目标与任务、要求与保障、动力与手段、机理与方式4个方面对其进行了研究.研究认为：政府职能运行的总体目标是促使竞技体育实现内生式发展,具体目标为构建竞技体育强国等,任务是进一步发展壮大竞技体育发展的民间力量等;政府职能运行的要求是以公共利益为核心,协调好不同领域的政府职能等,保障是财力与职能相配套等;政府职能运行的动力包括人民群众的体育需求等,手段有行政手段、市场手段、社会手段;政府职能运行的机理在于不同领域内管理职能的适度分离,方式是多元主体间的合作、博弈与均衡.

关于体育场(馆)经济网络群的研究

从世界经济发展的趋势——集团化和网络化的角度出发 ,结合体育场 (馆 )的特征 ,提出“经济网络群”的概念 ,并对其进行了理论分析 ,指出体育场 (馆 )产业具有二重性特征 ,即既归属于区域经济发展又归属于产业发展的范畴 ,由此得出体育场 (馆 )产业更适合于采用经济网络群形式进行发展的结论     

武术服饰的美学特征及其传承与发展

通常谈论武术之美主要是从技术风格方面来探讨的，其实武术服饰的“肥硕宽大之荑”、“庄重威严之美”、“悬垂之美”和“飘逸之美”更具有独特的传统美学特征。同时，武术服饰几乎涵客了中国传统文化的各种成分和要素，已经成为武术文化的几个极其重要的组成部分之一，在传承和发展过程中，必须注意传统理念与时代精神的融合。     

现阶段我国体育产业相关理论创新问题研究

分述传统或现阶段主流的体育产业理论问题:体育产业的理论学科属性、内涵及分类、发展中的重点产业问题、体育产业发展不平衡问题,指出体育产业理论创新是发展现阶段我国体育产业的关键,提出适应现阶段及未来一段时期内的体育产业理论创新思路、新观点。即体育产业的经济学属性问题、内涵和分类的体育增值业概念、运用体育产业阶段论解释现阶段重点产业问题以及不平衡性的另一层积极效应。     

我国竞技体育后备人才培养问题的理论探讨

伴随着经济一体化进程,我国竞技体育后备人才的培养受投资主体单一及竞赛制度的制约,各省市之间各自为政、封闭的后备人才培养体系效益较低。应该以国家“奥运战略”为目标,加强各省市体育后备人才培养合作,以发挥比较优势并提升整体竞争优势,为国家培养更多的高水平竞技体育后备人才。
