新课程标准下哈尔滨体育学院体育教育专业人才培养模式研究

2011版新修订《体育与健康课程标准》（简称新课标）对体育教师提出了更高的要求和挑战。作为体育教师的主要培养单位,体育院校更应与时俱进,建立与新课标相适应的人才培养模式。本文立足于新课标的要求,从课程体系、人才培养目标、教学内容与方法、考评体系等方面对哈尔滨体育学院体育教育专业人才培养模式进行研究。研究认为,新课标下,应改革体育教育专业的课程体系,提高体育教育专业的培养规格;加强教法研究,提高教学质量;从片面的生物学评价向完整的体育评价转变。以期为体育教育专业的办学实践提供理论参考。     

The influence of pitch dimensions on performance during small-sided and conditioned soccer games

Abstract

This study examined the influence of pitch dimensions in small-sided soccer games in shaping opportunities for performers to maintain ball possession, pass to teammates and shoot at goal. Fifteen amateur standard male participants (M = 21.87, σ = 1.96 years) played 5 v 5 small-sided soccer games in three varying pitch conditions (28 m × 14 m, 40 m × 20 m and 52 m × 26 m). Thirty sequences of play in each condition were selected for digitisation using TACTO software, allowing the capture of bi-dimensional displacement coordinate data of all players and the ball. The values of interpersonal distance between all attackers and immediate defenders and the relative distances of defenders to intercept a shot and a pass were computed as dependent variables. Results showed existence of fewer opportunities to maintain ball possession on smaller pitches, compared to medium and larger pitches. Conversely, the different dimensions set to the pitch did not influence opportunities for players to shoot at goal, or to perform passes to other teammates. By examining the specific spatial–temporal relationships of players and key-task constraints, the data from this study explain how effects of manipulating pitch dimensions of small-sided games might enhance opportunities for acquiring specific movement and decision-making skills.     

源与流：民族传统体育发展的传统文化因素探析

中国传统文化是中华文明演化而汇集成的一种反映民族特质和风貌的民族文化,是民族历史上各种思想文化、观念形态的总体表征,是中华民族几千年文明的结晶。民族传统体育作为中国传统文化的一部分,它的文化底蕴也必然来源于民族传统文化。任何一个传统体育项目都是在特定的传统文化背景下产生并逐步发展起来的。中国的传统文化对民族传统体育的影响是重大而深远的。     

我国优秀女子长距离速度滑冰运动员竞技心理适应性的监控研究

从黑龙江省、吉林省、辽宁省等运动队和解放军代表队抽取13名国际级、国家级女子长距离速滑运动员,采用竞技心理适应性量表对其进行心理监控与分析,从而反映我国优秀女子长距离速滑运动员竞技心理适应性上存在的共性及差异。经对结果的统计学分析,得出以下结论:国家级与国际级女子长距离速滑运动员相比,表现出能够更好地适应教练员;相对于其他冰雪项目运动员的整体水平,优秀女子长距离速滑运动员在提高技术欲望、失败性不安、紧张性不安、对教练的适应性等方面表现出了更高的水平;相对于其他冰雪项目运动员的整体水平,优秀女子长距离速滑运动员在克服困难、胜利志向性、情绪稳定性、对教练的信赖度、斗志、对知识兴趣等维度上表现出了较低的水平。     

象形武术:承载传统思维方式的文化符号

文章从符号的视角出发,采用文献资料法、历史研究方法、逻辑分析方法,通过对符号功能与形式的阐述来揭示象形武术的符号特征。符号是文化传承的主要载体,象形武术作为一种动态身体文化符号,承载的是中国传统文化思维方式,体现着中华民族的文化心理特征,折射出中国特色的审美特点。     

射击心理训练与发挥

射击运动员技术水平的提高是一个方面,更重要的是与比赛发挥相关联的心理能力的训练和提高。只有技术训练水平而没有发挥高水平的良好的心理能力作保证,其竞技能力永远是低下的。因此,心理技能是发挥的重要因素,因而运动竞赛的心理训练应得到非常的重视。     

Research on the operating characteristics of parallel 4-DOF electric platform with 4TPS-PS structure

The 4TPS-PS parallel platform designed for a stabilization and automatic tracking system is a novel lower-mobility parallel mechanism. In the first part of this paper, the structure of the platform is described and the kinematics model is built. The workspace of the platform is defined as the full reachable rotation workspace when the Z coordinate dimension of the upper plate varies continuously. A fast searching method of the full reachable workspace is presented, after which the inverse kinematics of the platform is deduced. The forward and inverse solutions of the speed and force of the platform are deduced. According to the characteristic of the 4TPS-PS platform’s structure, a fast searching algorithm of the maximum generalized speed and maximum generalized force output by the upper plate is put forward based on the forward and inverse solutions of the platform’s speed and force. The 4TPS-PS platform prototype built by the State Key Laboratory of Fluid Power Transmission and Control of China is taken as the research subject. The full reachable rotation workspace of the prototype is computed out and analyzed. The curves of maximum generalized speed and maximum generalized force of the prototype are computed out and plotted. Finally, the com- puting and analyzing results of the operating characteristics are confirmed through the experiment.
