集体对抗项目运动队及其竞技能力的系统观

当前我国训练学理论对竞技能力的研究多从个人角度进行,而对运动队整体的竞技能力无明确界定,因此用系统方法从系统的结构功能律、整体优化律、差异协同律等对运动队竞技能力系统规律加于阐释,并对集体竞技能力状态的转移及系统与环境的关系进行辩证的分析,力求为运动训练学理论的发展提供一点参考.

集体球类项目运动员反复冲刺能力的能量代谢机制的研究现状

对于集体球类项目(篮球、足球、橄榄球、手球等)来讲,运动员为了有效地完成比赛的技战术要求,取得竞争优势,必须在场上进行反复的高强度冲刺活动,所以反复冲刺的能力(Repeated-sprint ability:RSA)对运动员的竞技表现是至关重要的。本文旨在通过对国内外集体球类项目运动员反复冲刺能力的研究成果进行梳理分析,总结归纳出反复冲刺能力的能量代谢基础、测试方法及影响因素,以期能对我国竞技水平普遍不高的集体球类运动项目的科学化训练提供理论指导。     

发行集团应重视"三支队伍"建设

发行集团员工整体上可以分为"三支队伍":企业管理人员队伍、专业技术人员队伍和发行员技术工人队伍。构建和谐企业,"三支队伍"应共同发展。集团应加快三项制度改革,建立科学合理的劳动人事、用工、分配制度,促进"三支队伍"合理配置、合理发展。     

基层电大教师的专业身份危机

由于电大运作模式的弊端、教师管理的失范、实践理念的偏差和教师专业发展的滞后造成了基层电大教师身份的内部分化和外部泛化的＂身份危机＂。基层电大教师的教学工作和课程开发明显分离,网络教学新的特征和内涵进一步细化了电大教师的角色,教师岗位职能的细化使教师角色同一化,基层电大大量的管理工作进一步泛化了教师的角色,这些都不利于教师的专业发展。基层电大应通过纯化教师角色和控制教师工作量来提高外部认同度,通过建立教师专业发展标准和教学知识评价机制、重视教学理念的先进性、强调教学创新能力来提高内部认同度。

The effect of smartphones and playing video games on decision-making in soccer players: A crossover and randomised study

ABSTRACT

The objective of this study was to analyse the effect of the use of social networks in smartphones or playing video games on the passing decision-making performance in professional soccer athletes. Participants were 25 male professional soccer athletes (mean ± SD: age 23.4 ± 2.8 years). The participants performed three randomised conditions divided into three groups: control (CON), smartphone (SMA), and video game (VID). Before and after each experimental condition, the Stroop Task assessed the level of induced mental fatigue. Then, the athletes performed a simulated soccer match. A CANON® camera recorded the matches for further analysis on passing decision-making performance. A group effect was identified (p < .01) with impairment on passing decision-making performance for the SMA (p = .01, ES = 0.5) and VID (p = .01, ES = 0.5) conditions. We concluded that the use of social networks on smartphones and/or playing video games right before official soccer matches might impair the passing decision-making performance in professional soccer athletes.

试论职业资格考试对教育供求的调节

职业资格证书制度属于国家考试制度,学历证书制度属于国家教育 制度,二者对教育供求的调节产生了不同影响。在学历社会向资格社会转轨过程 中,要实现职业资格考试对教育供求的有效调节,就必须研究职业资格考试与教 育供求调节的关系,改革国家教育培训制度,更好地适应劳动力市场的需要,这是 优化人力资源配置、加强人力资源能力建设的重要课题。     

Neuromuscular and technical abilities related to age in water-polo players

Testing is one of the important tasks in any multi-step sport programme. In most ball games, coaches assess motor, physical and technical skills on a regular basis in early stages of talent identification in order to further athletes’ development. The purpose of the study was to investigate anthropometric variables and vertical jump heights as a free throw effectiveness predictor in water-polo players of different age groups. Two hundred and thirty-six young (10–18 years) male water-polo players partitioned into three age groups underwent anthropometric variables’ measures and squat- and countermovement-jump tests, and performed water-polo free throws. Anthropometric variables, vertical jump heights and throw speed – as a proxy for free throw effectiveness – resulted different over age groups. Particularly, throw speed changed from 9.28 to 13.70 m · s^?1 (+48%) from younger to older players. A multiple-regression model indicated that body height, squat-jump height and throw time together explain 52% of variance of throw speed. In conclusion, tall height, high lower limb power and throwing quickness appeared to be relevant determinants for effective free throws. Such indications can help coaches during talent identification and development processes, even by means of novel training strategies. Further research is needed over different maturity statuses.
