ABSTRACT

The speed performance is involved not only in linear sprints, but also in a wide spectrum of multi-directional movements, such as curve sprinting. Curved sprint can be defined as sprint with gradual and continuous change of direction (COD). Although ~85% of the actions performed at maximum velocity in a professional soccer league are curvilinear sprints, there is not any specific test to assess this ability. This study aimed to analyse the reliability of a new curve sprint test, and compare its results with those obtained by soccer players in linear sprint. Forty experienced soccer players performed 3 attempts of curve sprint (using the penalty arc) to right and left side (17 m), and 3 linear sprints (17 m) in two different days. The ICCs (inter-session reliability) were 0.93 for sprint curve right side (CSRS) and 0.89 for sprint curve left side (CSLS), considered “acceptable”. The CVs (intra-session reliability) were 0.87% in CSRS and 1.15% in CSLS. The coefficient of determination (R²) between linear and curve sprinting was ~35%. The association between curve sides was “very large” (r = 0.878; p < 0.01). In summary, we showed that “curve sprint test” is highly reliable, and that curvilinear and linear sprints are different and independent actions.  相似文献   

回顾与前瞻: 中国男子篮球职业联赛竞争格局演变特征     

蒋志伟  邱希 《武汉体育学院学报》2019,53(2):89-95

运用ABC分析法对1995-18赛季CBA比赛进行分析，探析CBA竞争格局的演变特征和演变规律。参照CBA各球队竞争实力变化特点，遵循事物发展的规律，将CBA的发展过程划分为4个阶段，追溯各阶段竞争格局的特点，以此归结CBA竞争格局的演变特征，认为：CBA在经历传统强队的滑坡与新兴球队的兴起后，竞争格局发展趋向更加难以预测；竞争格局在经历北强南弱、南强北弱后，正向更加均衡的态势发展；东、西部区域发展不均衡。  相似文献

Evaluation of soccer players under the Moneyball concept

ABSTRACT

The recruitment of athletes with limited resources is a global problem in professional sports. In US Major League Baseball, the experience of the Oakland Athletics’ general manager in the last decade turned his “Moneyball” model into a synonym of quantitative analysis in the transfer market of baseball players. His strategy focused on hiring players with outstanding technical skills but relatively low market value. This study adapted this model to the framework of a multiple criteria decision aid (MCDA), by selecting undervalued players who have complementary abilities. The novelty here refers to the joint use of four algorithms explored by the composition of probabilistic preferences (CPP) (i.e., ranking, classification, dynamic evaluation and regularity analysis) and their application to soccer player performance evaluation. The new model analysed the recent transfer of a left-back soccer player to Europe. The results indicated 12 opportunities for better investment, among 32 left and right-back players considered. Two years later, the value of the same player was considerably lower. He played only five matches in the 2018–2019 season, without scoring or providing any assists. On the other hand, the players better classified by the CPP-MB model presented higher performances and market values.  相似文献   

日本足球归化运动员的历史演进、运作逻辑与实践启示     

张大为  田胜国  刘兵 《沈阳体育学院学报》2020,(3):80-86,106

从历史演进视角对日本足球归化运动员进行研究,将归化演进历程分为业余足球主导期、职业足球改革探索期、职业足球稳定发展期3个阶段。归化运作逻辑体现:以技术足球理念为基准,合理实施归化行为;以填补位置短板为目的,提高国家队竞技水平;以保障职业角色转换为举措,营造良性发展氛围;以规避资源挤占矛盾为导向,逐步改变归化价值取向。启示:我国应厘清主体责任和发展理念,做好归化顶层设计;正视国家归化需求,消解文化融合与社会认同障碍;建立长效服务机制,扩大归化行为示范效应;把握足球运动规律,构建可持续发展模式。  相似文献   

中美竞技篮球对篮球产业影响的比较研究     

李少兰 《广州体育学院学报》2019,(3):38-40

中美在篮球产业发展水平上存在着巨大差距，而竞技篮球发展水平对篮球产业的影响作用是造成这种差距的主要原因之一。NBA是美国篮球产业的赚钱机器，同时也是宣传机器和造势机器，NBA对美国篮球产业产品乃至深层次的篮球文化、篮球娱乐精神都具有广泛的影响力，这种影响力几乎覆盖全球。中国篮球职业化改革已走过28个年头，竞技篮球对篮球产业也产生了积极的影响，然而对照美国职业篮球发展路径，还存有很多不足和缺陷。今后需要在政府管理、企业自主经营、市场化发展等方面花大力气。  相似文献
