足球运动员的核心力量训练研究

随着足球运动的不断发展,对球员的竞技能力的要求提高相应地要求球员具备更好的力量能力。足球运动对运动员的身体力量能力要求很高,足球运动员在比赛中控制躯干和髋部的力量非常重要,足球运动员表现的力量能力不完全取决于运动员的肌群力量,而肌群间的协调性和稳定性对力量发挥的影响程度较大。足球比赛中,足球运动员的各项技术动作的发力都离不开核心区肌肉群的发力。核心力量训练如何运用在足球训练和比赛中有待于发掘和论证。本文运用文献资料法、专家访谈法、问卷调查法、观察法对足球运动员核心力量训练进行研究和分析。     

中国科协科技期刊出版管理现状及思考

【目的】 在了解中国科协科技期刊出版管理创新及改革进展的基础上,为进一步深化出版管理改革提出建议。【方法】 针对中国科协所属的1081种期刊出版管理改革发展现状进行问卷调查,并对其进行深度剖析。【结果】 目前中国科协科技期刊仍呈现主管、主办单位多元化的现状,大多数仍为单刊编辑出版,但办刊人从观念上对出版管理改革已经逐渐接受并予以思考;期刊运作模式在革新之中,期刊数字化、集群化建设方面也有所进展。【结论】 从占我国科技期刊总数1/5的中国科协科技期刊来看,我国的科技期刊出版管理体制改革和机制创新,在期刊资源整合、传统媒体与新媒体融合发展等方面仍需进一步加强探索。

英格兰足球超级联盟研究及对我国职业足球发展的启示

英国作为现代足球的发源地,一直是世界足球强国。英超联盟是英国足球产业的中流砥柱,在英国体育事业中发挥着举足轻重的作用。通过对英超联盟的组织结构、产权框架与经营手段的研究,反思中国职业足球存在的“管办不分”“产权不清”以及“管理混乱”等问题,体现在中超联赛上就是组织结构的不完善与商业开发能力的严重不足。为了解决这些问题,结合中国自身实际,提出从加强联赛理事会建设与促进中超公司发展这两个角度寻找一条适合中国足球发展的道路。     

The cumulative and residual fatigue response associated with soccer-specific activity performed on different playing surfaces

ABSTRACT

This study aimed to assess the effect of playing surface (Natural [NT] and Artificial [AT] Turf) on the fatigue response to a soccer-specific exercise protocol (SSEP). Eighteen male soccer players completed the SSEP on NT and AT with pre-, post-, and 48 h post-assessments of eccentric knee flexor (eccKF) and concentric knee extensor peak torque (PT), peak countermovement (CMJ) and squat jump (SJ) height, and Nordic hamstring break angle. No significant main effects for surface or any surface and time interactions were observed for any of the outcome measures, except for eccKF PT recorded at 3.14 rad·s^-1, which was significantly lower 48 h post-trial in the AT condition (AT = 146.3 ± 20.4 Nm; NT = 158.8 ± 24.7 Nm). Main effects for time were observed between pre- and post-trial measures for eccKF PT at all angular velocities, Nordic break angle, CMJ and SJ height. Nordic break angle, and both CMJ and SJ height were significantly impaired 48 h post-trial when compared to pre-trial. The findings of the current study suggest surface dependent changes in eccKF PT which may have implications for recovery and subsequent performance after competition on AT.     

In pursuit of becoming a senior coach: the learning culture for Australian Football League coaches

Background and Purpose: Given the turbulent and highly contested environment in which professional coaches work, a prime concern to coach developers is how coaches learn their craft. Understanding the learning and development of senior coaches (SCs) and assistant coaches (ACs) in the Australian Football League (AFL – the peak organisation for Australian Rules Football) is important to better develop the next generation of performance coaches. Hence the focus of this research was to examine the learning of SC and AC in the AFL. Fundamental to this research was an understanding that the AFL and each club within the league be regarded as learning organisations and workplaces with their own learning cultures where learning takes place. The purpose of this paper was to examine the learning culture for AFL coaches.

Method: Five SCs, 6 ACs, and 5 administrators (4 of whom were former coaches) at 11 of the 16 AFL clubs were recruited for the research project. First, demographic data were collected for each participant (e.g. age, playing and coaching experience, development and coach development activities). Second, all participants were involved in one semi-structured interview of between 45 and 90 minutes duration. An interpretative (hierarchical content) analysis of the interview data was conducted to identify key emergent themes.

Results: Learning was central to AFL coaches becoming a SC. Nevertheless, coaches reported a sense of isolation and a lack of support in developing their craft within their particular learning culture. These coaches developed a unique dynamic social network (DSN) that involved episodic contact with a number of respected confidantes often from diverse fields (used here in the Bourdieuian sense) in developing their coaching craft. Although there were some opportunities in their workplace, much of their learning was unmediated by others, underscoring the importance of their agentic engagement in limited workplace affordances.

Conclusion: The variety of people accessed for the purposes of learning (often beyond the immediate workplace) and the long time taken to establish networks of supporters meant that a new way of describing the social networks of AFL coaches was needed; DSN. However, despite the acknowledged utility of learning from others, all coaches reported some sense of isolation in their learning. The sense of isolation brought about by professional volatility in high-performance Australian Football offers an alternative view on Hodkinson, Biesta and James' attempt in overcoming dualisms in learning.     

The Structural Adjustment of Football in Zambia: Politics,Decline and Dispersal, 1991–1994

Abstract

This paper explores multiple and complex relationships between football (soccer), politics, and the economy in postcolonial Zambia. Based on archival and oral sources collected in Zambia, the paper argues that President Frederick Chiluba’s government failed to support football development when it came into power in 1991 because it was elected on a platform of liberalizing the collapsing national economy. Chiluba privatized state-owned companies that were sponsoring the game resulting in the plummeting of the local standards and migration of talented footballers abroad in search of better livelihoods. Furthermore, the paper argues that while the exodus of talented footballers led to the deterioration of the standards of the local league, their transnational experience boosted the performance of the Zambia national football team. This led to the emergence of one of the best national teams the country has ever had. Unfortunately, this particular team perished in the Gabon air disaster in 1993 following the government’s disinvestment in the game. However, a few months after the disaster, the country managed to rebuild a national football team, which emerged as runners up to Nigeria in the 1994 African Cup of Nations final as a result of a large pool of local and foreign-based football players.
