我国优秀少年足球守门员出击技术运用情况分析

运用现场观察和常规技术统计的方法，对目前国内优秀少年足球守门员出击技术运用情况进行统计和分析，并提出建议。研究表明，对出击时机的把握性差和对抗中争接球技术运用质量水平低，是目前我国优秀少年足球守门员出击技术运用中存在的主要问题。守门员把握出击的时机，是与其对门前赛势的观察、判断及分析密不可分的，只有正确地分析门前的情况，才能把握住出击的时机。少年守门员出击意识、心理及技术应同步发展，切实提高出击的机变能力，应是少年守门员训练中的重点。应加强少年守门员对抗中的技术运用质量要求，努力改变比赛中守门员技术不过硬的现状。

物体表面不同角度采集的三维图像配准的一种新算法

提出了一种能有效实现物体表面三维图像数据配准的算法.该算法利用了三维数据采集时的三维点的阵列信息,这些三维点的阵列信息在采集原始三维数据时可以很容易获得,同时,还利用了三维数据矢量/顶点相似特征作为数据匹配的基础.采用迭代最小均方误差算法来自适应优化变换矩阵参数.这些方法可以有效地提高三维图像配准的性能,加快匹配过程的运算速度.实验结果表明该算法可以获得较好的配准后三维图像的主观效果.尽管该方法主要针对人头模型,但经过少许修改后即可适用于其他物体.

Skating start propulsion: three-dimensional kinematic analysis of elite male and female ice hockey players

The forward skating start is a fundamental skill for male and female ice hockey players. However, performance differences by athlete’s sex cannot be fully explained by physiological variables; hence, other factors such as skating technique warrant examination. Therefore, the purpose of this study was to evaluate the body movement kinematics of ice hockey skating starts between elite male and female ice hockey participants. Male (n = 9) and female (n = 10) elite ice hockey players performed five forward skating start accelerations. An 18-camera motion capture system placed on the arena ice surface captured full-body kinematics during the first seven skating start steps within 15 meters. Males’ maximum skating speeds were greater than females. Skating technique sex differences were noted: in particular, females presented ~10° lower hip abduction throughout skating stance as well as ~10° greater knee extension at initial ice stance contact, conspicuously followed by a brief cessation in knee extension at the moment of ice contact, not evident in male skaters. Further study is warranted to explain why these skating technique differences exist in relation to factors such as differences in training, equipment, performance level, and anthropometrics.     

Exergames ‘as a teacher’ of movement education: exploring knowing in moving when playing dance games in physical education

Background: A fundamental dimension of school physical education (PE) is arguably movement and movement activities. However, there is a lack of discussion in the context of PE regarding what can be called the capability to move in terms of coordinative abilities, body consciousness and educing bodily senses.

Purpose: This article explores and articulates what there is to know, from the mover's perspective, when knowing how to move in specific ways when playing exergames (dance games). Taking different ways of moving as expressing different ways of knowing as a point of departure, the following questions are the focus of this article: (i) How do students move when imitating movements in a dance game, and what different ways of knowing the movements can be described in the student group? (ii) What aspects of the movements are discerned simultaneously through the different ways of knowing the movements? (iii) What aspects seem critical for the students to discern and experience in order to know the movements in as complex a way as possible?

Design and analysis: The theoretical point of departure concerns an epistemological perspective on the capability to move as knowing how with no distinction between physical and mental skills, and also knowing as experiencing aspects of something to know. The data in this study comprise video recordings of students playing Nintendo Wii dance games in PE lessons in a compulsory school (for children aged between 7 and 16 years) in a small Swedish town. There were three PE lessons with four different stations, of which one was Nintendo Wii dance games (Just Dance 1 and 2). In total, the videoed material covers three 60-minute PE lessons, recorded during the autumn of 2012 and in which just over twenty students participated. In the study, we have used video observation as a data collection method. Jordan and Henderson maintain that video observation removes the gap between ‘what people say they do and what they, in fact, do’ (51). To conduct a systematic and thorough analysis of how the students experienced the avatar's movements, we looked for moments where all the students and the avatar could be simultaneously observed. Two video sequences were chosen, showing four students imitating two distinct and defined movements which constituted the basis for a phenomenographic analysis.

Conclusion: The result of the phenomenographic analysis shows different ways of knowing the movements as well as what aspects are discerned and experienced simultaneously by the students. In other words, these aspects also describe knowing in terms of discerning, discriminating and differentiating aspects of ways of moving. By examining a certain exergame's role ‘as a teacher,' we have emphasized the capability to move, from the mover's perspective, as an intrinsic educational goal of PE while highlighting the need for systematically planning movement education.     

论金初“南冠诗人”的忠义精神

金朝初年,被囚禁的滕茂实、朱弁、洪皓、司马朴等南冠诗人忠于宋朝,坚守节操。朱弁等使臣期盼宋室中兴,致力于两国和好,常以苏武自勉。司马朴等人客死他乡,朱弁、洪皓十余年后全节返宋,只求苟安的南宋朝廷对他们的表彰中隐含着排挤。这些宋臣未能被故国重用,相反,他们的忠义节操受到了金人的崇敬,成为南北文化融合后形成的中原文化的一部分。
