采用录像观察法。对中超和欧洲五大联赛主、客场攻守数据进行了对比分析，指出竞技能力才是影响比赛结果的关键要素。研究认为：（1）与欧洲联赛相比，五大联赛各队之间竞争较均衡，中超各队之间竞争不均衡，实力相差悬殊，中超的整体技战术水平和运动员个人技术的全面性都不如五大联赛。中超各队还缺少鲜明的特点和风格；（2）西甲各队的技战术水平比较成熟，主、客场进攻与防守能力较为平衡；（3）西甲在主、客场胜负率上没有显著性差异，证明其不愧为是世界上最强的职业联赛；（4）中超及五大联赛在主、客场进球数上均没有显著性差异，表明客场不利因素的影响在减小；（5）德甲在主、客场失球上有显著性差异，是防守能力不足的表现。 相似文献

运用文献资料、录像观察、TOPSIS以及RSR秩和比评价等方法,对2015赛季中超各球队攻防指标进行分析并综合评价,探析中超联赛的竞争格局,研究结果:当今中国足球格局没有发生变化,恒大继续夺冠;中国足球实力格局仍不平衡,各参赛队在综合攻防实力上可分为3个等级;在进攻能力上,3个等级球队在射门次数指标上差异具有非常显著性(P<0.01),进球、控球率、传威胁球次数以及角球次数等指标差异具有显著性(P<0.05);在防守能力上,失球数差异具有高度显著性(P<0.01),犯规、扑救成功率等指标差异具有显著性(P<0.05)。中超联赛竞争格局表现在攻守能力较强且较均衡的球队在联赛中取得较好的成绩,而攻守不平衡的球队在联赛中的排名不理想。 相似文献

自从2004年中超创办以来,冠军的归属就被四支不同的球队所染指。从原来的三足鼎立到如今的群雄分割,可以看出中超各队的整体水平都在提高。上赛季长春亚泰队更是直到联赛倒数第二轮才基本确立了争冠的优势,最终直到联赛最后一轮客场战胜深圳上清饮才确保将冠军收入囊中。在中超诸多看点中,冠军的归属永远是球迷最关心的。 相似文献

对CBA 2010-2011赛季各队的攻守能力进行研究后发现:联赛成绩较好的球队具有较强且较均衡的攻防能力。据最佳分档准则,结合合理分档数表,可将CBA职业联赛竞争格局分为3档。强队在进攻指标(得分、2分率、3分率、罚篮率、进攻篮板、助攻)和防守指标(失分、抢断、犯规和盖帽)方面占有明显的优势。不同档次球队之间存在显著性或极显著性差异。而比赛中各方失误的几率大致均等,在防守篮板方面也不存在显著性差异。运用TOPSIS法与RSR法对篮球职业俱乐部队综合评价及格局划分具有一定的可靠性和参考价值。 相似文献

世界足球主要联赛球员国际流动特征研究 总被引：7，自引：0，他引：7
以2008-2009赛季世界职业足球一级市场(英超、西甲、意甲、德甲、法甲)和二级市场联赛(巴甲、阿甲、荷甲、俄超、日本联赛)注册球员为调研对象,对球员国际流动的一般特征及特殊性进行了量化分析.数据分析显示,一级市场联赛是世界职业足球发展的核心区域,主要招募来自东欧、南美洲和非洲球员,形成了全球精英球员供给分配的科层化结构.二级市场联赛大量启用本土球员,参与本土足球市场竞争.结论认为,世界足球主要联赛球员的国际流动是一个非常复杂的全球体育现象,诸如经济、政治、文化、语言、价值观、习俗、地理位置、历史殖民地、后殖民关系、国家双边交流、技战术风格打法等要素分别对其产生一定的作用影响,球员国际流动现象的产生是多种要素综合作用的结果. 相似文献

Abstract Nine- to 10-year-old children have difficulty playing baseball using adult rules because pitchers lack the ability to throw the ball over the plate with consistency and batters lack ability to hit erratically thrown balls. Thus a natural field experiment investigated a modification of adult baseball for 9- to 10-year-old children. Instead of one of the players on the opposing team pitching, the coach of the offensive team pitched to the batters. Teams in a league who played baseball by adult rules (traditional league) were compared with teams in a league who played the modified game (nontraditional league), and both these leagues were compared with 11- to 12-year-old teams (older league). Various offensive and defensive activities were recorded by two observers and satisfaction scores were obtained from the players after the games. More offensive and defensive activity occurred in the nontraditional league games than in the traditional and older league games. 相似文献

The present study examined the relationship between aggression and game location in rugby league. We videotaped a random sample of 21 professional rugby league games played in the 2000 Super League season. Trained observers recorded the frequency of aggressive behaviours. Consistent with previous research, which used territoriality theories as a basis for prediction, we hypothesized that the home team would behave more aggressively than the away team. The results showed no significant difference in the frequency of aggressive behaviours exhibited by the home and away teams. However, the away teams engaged in substantially more aggressive behaviours in games they lost compared with games they won. No significant differences in the pattern of aggressive behaviours for home and away teams emerged as a function of game time (i.e. first or second half) or game situation (i.e. when teams were winning, losing or drawing). The findings suggest that while home and away teams do not display different levels of aggression, the cost of behaving aggressively (in terms of game outcome) may be greater for the away team. 相似文献

Abstract The aim of the present paper was to examine the differences in game-related statistics between basketball guards, forwards and centres playing in three professional leagues: National Basketball Association (NBA, superior level) in the USA, Associación de Clubs de Baloncesto (ACB, one of the best European leagues) in Spain and Liga de Clubes de Basquetebol (LCB, inferior level) in Portugal. We reasoned that the knowledge of these differences could allow the coaches to better establish and monitor playing patterns and increase the effectiveness of the player recruitment process. Archival data was gathered for the 2000–2001 play-off final series of the NBA (five games), ACB (three games) and LCB (four games). For players in each league, discriminant analysis was able to identify game-related statistics that maximized mean differences between playing positions (p<0.05). The interpretation of the obtained discriminant functions was based on examination of the structure coefficients greater than ∣0.30∣. In the LCB league, centres and guards were discriminated mainly in terms of defensive tasks, with emphasis on blocks (structure coefficient, SC=0.35) and defensive rebounds (SC=0.43) and a de-emphasis on unsuccessful 3-point field-goals (SC=???0.37). In the ACB, centres and guards were discriminated by offensive tasks, with emphasis on assists (SC=0.52) and 3-point field-goals, both successful (SC=0.35) and unsuccessful (SC=0.35), and a de-emphasis on offensive rebounds (SC=???0.44). Finally, in the NBA league guards and centres were discriminated by offensive tasks, with emphasis on offensive rebounds (SC=0.31) and a de-emphasis on assists (SC=???0.37) and unsuccessful 3-point field-goals (SC=???0.34). These three analyses provided high overall percentages of successful classification (86% for the LCB league, 74% for the ACB and 85% for the NBA). Generally, the players’ game-related statistics varied according to playing position, probably because of the well-known differences in the players’ anthropometric characteristics that conditioned the distance they play from the basket. Coaches can use these results to reinforce the importance of relying on different players’ contributions to team performance and evaluate players’ game performance according to their playing position. Conversely, these discriminant models could help in player recruitment and improve training programmes. 相似文献
