Could Slackline Training Complement the FIFA 11+ Programme Regarding Training of Neuromuscular Control?

The current study compared changes in neuromuscular control between slackline training and the stabilization training elements of the FIFA 11+ programme. Twenty-five students in 2 groups performed a 12-unit training programme. The slackline training group (n?=?13) exclusively trained with a slackline. The stabilization training group (n?=?12) practised exercises as described in the second part of the FIFA 11+ programme. Improvements in balance were assessed using three tests for dynamic, quasi-static, and perturbed postural control: the star excursion balance test (SEBT), the closed-eye single-leg stance, and the MFT S3-Check. Both groups significantly improved the stability and sensorimotor index of the MFT S3-Check (p?<?.001), their range on the SEBT (p?<?.001), and the duration of closed-eye single-leg stance (p?<?.001). The group?×?training interaction was significant for the MFT S3-Check (stability index: p?=?.042; sensorimotor index: p?=?.004) and the SEBT (dominant leg: p?=?.003; averaged both legs: p?=?.016), with the slackline training group showing a larger training effect than the stabilization training group. The results of the present study suggest that slackline training offers similar – or better – improvements in neuromuscular control as the FIFA 11+ warm-up programme. If compliance with the FIFA 11+ programme is declining, then slacklining might offer an alternative approach to reach the training goals of improved sensorimotor control.     

A lonely and beautiful country: reflecting upon the state of oblivion in Turkey through Nuri Bilge Ceylan's Three Monkeys

Abstract

Through an in‐depth analysis of internationally acclaimed Turkish director Nuri Bilge Ceylan's 2008 film Three Monkeys (Üç Maymun), this article discusses the politics of Ceylan's cinema against the backdrop of the current memory debate in Turkey. Turkey has a troubling relationship with its past. The process of the foundation and the early development of the Turkish nation‐state included traumatic events during which ethnic and religious minorities were massacred, deported, or encouraged to migrate. There have also been several violent incidents in Turkey's subsequent history that include massacres, mass killings, political assassinations, as well as military coups. It is a widely held opinion that social memory in Turkey is based on forgetting and denial, that is, Turkish society deals with the troubling events in its past by turning a blind eye to them. Drawing upon the question of how it may be possible to make the traces of forgetting and silence observable, this paper argues that Ceylan's film, despite its seemingly apolitical story, has indeed profound political connotations since its narrative and visual organization serve to display the prevailing mood of silence, oblivion and complicity in Turkey.     

The camera in pain: memories of the Cold War in East Asian independent documentaries

Abstract

This article begins with a discussion of the changing topography of cultural production in East Asia over the last 25?years, especially as it concerns the genre of independent documentary film, and then it turns to three independent documentaries filmed in Japan and North Korea, South Korea and Japan, and China, respectively: Yang Yong-hi's Dear Pyongyang (2005 Dear Pyongyang. 2005. Directed by Yang Yong-hi. Busan International Film Festival. [Google Scholar]), Mun Jeong-hyun's Grandmother's Flower (2007 Grandmother's Flower. 2007. Directed by Mun Jeong-hyun. Busan International Film Festival: [Google Scholar]), and Wang Bing's He Fengming: A Chinese Memoir (2006). Erased from the official historical record and excluded from public commemoration, the alternate history of pain traced by these documentaries resubmits the Cold War to examination from deep inside its most private wounds. In the process, the filmmakers encounter not only the memories of the earlier generation that lived through the most violent episodes of the Cold War, but also come to question their own history and identities within the process of the Cold War's decomposition.     

基于TSM模型的感应电机有限时间跟踪控制

根据变结构控制理论提出了一种新的设计方法——有限时间切换控制。在控制器设计中利用中继切换控制使系统在给定的当前控制律的作用下运行到某一特定状态（或某一特定区域）后,控制律被切换为有限时间收敛的终端滑模控制器,并使得系统在有限时间内达到平衡状态。有限时间跟踪控制器的设计保证了闭环系统所有信号的有界性和平衡点的全局稳定性,以及系统在有限时间内精确地跟踪给定的参考信号,仿真结果说明该控制策略的有效性。     

大学体育口号与理念的谱系与解构

体育口号与理念作为体育思想的一种表现形式,是学校开展体育工作的手段之一。本文选取大学体育口号与理念为研究对象,通过文献资料法、问卷调查法和专家访谈法,梳理大学体育口号与理念的历史谱系,以不同时期清华的体育口号与理念为个案分析,以此审视我国大学体育思想的发展脉络。研究指出,从“为祖国健康工作五十年”到“无体育,不清华”体育口号与理念的谱系,价值导入是从“卡里斯马式”到“集体无意识”,呈现出大学体育价值理念的文化记忆。大学体育口号与理念的内涵表现在：从中华民族的救国到建国再到强国的爱国性,从体育运动的强迫到认同再到自发的传承性,从影响范围的区域到国家再到国际的卓越性以及对大学体育的引领性。研究认为,大学体育口号与理念体现了大学体育价值取向的变化以及大学体育思想的继承发扬,是实现“体育的迁移价值”和立德树人的有效手段。     

Motor control of practice and actual strokes by professional and amateur golfers differ but feature a distance-dependent control strategy

Abstract

We explored how practice and actual putting strokes differed between professionals and high-level golf amateurs, and how practice strokes reflected subtle differences in putting distances. We analysed swing amplitude, impact velocity, and acceleration profile of the club-head. The acceleration profiles showed that the motor control pattern of the practice stroke differed from that of the actual stroke. To clarify the effects of different putting distances on the practice stroke and to analyse how much the actual stroke could be explained by the practice stroke, we conducted individual regression analyses. The practice strokes of all participants could be divided into three strategies and five types by the coefficient of determination and the slope. This implies that the purpose of the practice stroke varied among golfers. Most golfers used the individual velocity criteria in their practice strokes, which resulted in different putting distances based on their criteria. Unexpectedly, we found no significant difference in skill level between professionals and high-level amateurs. The results of this study imply that the practice stroke does not duplicate the actual stroke, even for professional golfers with excellent skills. However, most high-level golfers adopted distance-dependent control strategies for slightly different putting distances.
