任务驱动教学法在高校足球普修课中的作用     

覃志勇 《当代体育科技》2020,(11):84-84,86

在我国不断改革和促进中国教育制度发展的同时,教学重点更多的放在了培养学生的主观能动性上。足球普修课程是适用于所有学生的,要根据大多数学生足球能力的基本情况进行足球教学活动。将任务驱动教学方法应用于足球普修课程中,有助于激发学生学习足球的学习兴趣。基于此,本文针对当前我国高校足球普修训练课程中遇到的问题,提出一些建议,以供大家参考交流。  相似文献   

欧洲足球不同年龄层国家队成绩的相关性分析     

赵柏林  袁柏青 《当代体育科技》2020,(11):241-241,243

根据对世界四大足球赛的数据分析,发现欧洲国家青年队的成绩与国家队成绩的相关性比较小,其直接表现为欧洲国家往往在世界杯表现优越,而在低级别的青年队和少年队的表现却不如南美和非洲国家,究其原因,欧洲国家凭借着出色的青训系统,培养和归化了大量的海外人才,欧洲大多数国家支持双重国籍,欧洲一体化能真正落实到资源共享,所以欧洲国家青年队成绩比不上南美和非洲,但国家队却能优势明显。  相似文献

职业足球改革困境：一种非均衡国家治理模式的反思     

周嘉豪 《河北体育学院学报》2020,34(2):1-5

运用文献资料法和逻辑分析法,从非均衡国家治理角度对我国职业足球改革面临的困境进行研究。通过梳理相关文献提出,当前国家治理模式具有非均衡性,存在各主体参与失范、治理权责分配失衡的问题,市场、社会、个人主体话语权较弱、参与性不足,形成了较强的政府依赖路径。对职业足球改革各主体之间的关系进行阐述,认为政府和足协是改革话语权的掌握者和资源的分配者,其他主体参与改革作用较小。指出,尚未明确职业足球的发展动机、足协组织能力与管理效能不足、各主体缺乏有效联系与合作是非均衡国家治理模式的具体表现;政府的非市场手段治理、市场失灵与第三部门失灵、个体意识与自我治理不足是其深层次原因。在此基础上提出相应的发展对策。  相似文献   

Optimal synchronization controller design for complex dynamical networks with unknown system dynamics     

Ya-Wei Cao  Guang-Hong Yang  Xiao-Jian Li 《Journal of The Franklin Institute》2019,356(12):6071-6086

In this paper, the optimal synchronization controller design problem for complex dynamical networks with unknown system internal dynamics is studied. A necessary and sufficient condition on the existence of the optimal control minimizing a quadratic performance index is given. The optimal control law consists of a feedback control and a compensated feedforward control, and the feedback control gain can be obtained by solving the well-known Algebraic Riccati Equation (ARE). Especially, in the presence of unknown system dynamics, a novel adaptive iterative algorithm using the information of system states and inputs is proposed to solve the ARE to get the optimal feedback control gain. Finally, a simulation example shows the effectiveness of the theoretical results.  相似文献   

Intermittent control strategy for synchronization of fractional-order neural networks via piecewise Lyapunov function method     

Ying Yang  Yong He  Min Wu 《Journal of The Franklin Institute》2019,356(8):4648-4676

In this paper, the synchronization problem of fractional-order neural networks (FNNs) with chaotic dynamics is investigated via the intermittent control strategy. Two types of intermittent control methods, the aperiodic one and the periodic one, are applied to achieve the synchronization of the considered systems. Based on the dynamic characteristics of the intermittent control systems, the piecewise Lyapunov function method is employed to derive the synchronization criteria with less conservatism. The results under the aperiodically intermittent control show more generality than the ones via the periodically intermittent control. For each of the aperiodic and periodic cases, a simple controller design process is presented to show how to design the corresponding intermittent controller. Finally, two numerical examples are provided to demonstrate the effectiveness of the obtained theoretical results.  相似文献   

Where are we now? A review of research on the history of women's soccer in Ireland     

Helena Byrne 《Sport in History》2019,39(2):166-186

ABSTRACT

It is a common fact that women's sport and leisure history, especially in male dominated spheres, and more specifically football, have been ignored by many academics. However, in recent years there have been major developments in digital technology that have changed the nature of the type of research that can be done. Access to tools to facilitate field research are relatively cheap and with the high volume of digitisation projects that have taken place over the last few years as well as the increasing number of born digital resources that have been published, there are new opportunities. In relation to women's soccer in Ireland, this paper asks the question – where are we now? The argument will review the current literature on this subject and outline potential approaches for future research.  相似文献   

Motivation counteracts fatigue-induced performance decrements in soccer passing performance     

Jeroen C.M. Barte  Arne Nieuwenhuys  Sabine A.E. Geurts  Michiel A.J. Kompier 《Journal of sports sciences》2019,37(10):1189-1196

Recent theories suggest that negative effects of fatigue on performance are determined by perception of effort and motivation rather than being directly caused by reaching physiological limits. In the current experiment, the influence of motivation on fatigue-induced decrements in soccer performance was experimentally investigated. Sixty amateur soccer players performed a validated soccer-passing test before and after a fatigue protocol. Results showed that players’ motivation and performance decreased after the fatigue protocol for players in the control group. In contrast, players in the motivation group (i.e., with motivation experimentally induced after the fatigue protocol) were able to uphold their motivation and increase their performance. These results indicate that motivation plays a crucial role in performance under fatigue, as fatigue-induced decrements in soccer passing performance can be counteracted by high levels of motivation. Future research may explore the limits of this counteracting effect and extend findings to other relevant performance aspects.  相似文献   

A rule induction framework for the determination of representative learning design in skilled performance     

Sam Robertson  Bart Spencer  Nicole Back  Damian Farrow 《Journal of sports sciences》2019,37(11):1280-1285

Representative learning design provides a framework for the extent to which practice simulates key elements of a performance setting. Improving both the measurement and analysis of representative learning design would allow for the refinement of sports training environments that seek to replicate competition conditions and provide additional context to the evaluation of athlete performance. Using rule induction, this study aimed to develop working models for the determination of high frequency, representative events in Australian Rules football kicking. A sample of 9005 kicks from the 2015 Australian Football League season were categorised and analysed according to the following constraints: type of pressure, kick distance, possession source, time in possession, velocity and kick target. The Apriori algorithm was used to develop two models. The first consisted of 10 rules containing the most commonly occurring constraint sets occurring during the kick in AF, with support values ranging from 0.15 to 0.22. None of the rules contained more than three constraints and confidence values ranged from 0.63 to 0.84. The second model considered ineffective and effective kick outcomes and displayed 70% classification accuracy. This research provides a measurement approach to determine the degree of representativeness of sports practice and is directly applicable to various team sports.  相似文献
