探索不同赛制下比赛表现指标对比赛结果产生的影响,选取2018年俄罗斯世界杯59场、118组技战术表现和跑动表现指标作为自变量,比赛胜、负作为因变量。运用K型聚类分析,对比分均衡比赛进行界定。根据比赛控球率的不同对比赛表现指标进行标准化处理。运用数据级数推断法界定各自个变量增加2个标准差对比赛获胜概率带来的变化。研究结果:1)在所有比赛中,9项技战术表现指标(射门次数、射正次数、射正率、定位球射门次数、突破进入罚球区次数、控球率、传球成功率、解围成功次数和防守反击次数)和3项跑动表现指标(本方控球时跑动距离、进攻三区跑动距离和对方罚球区跑动距离)使比赛获胜概率显著提升。对方控球时跑动距离则使获胜概率显著下降;2)在比分均衡比赛中,5项技战术表现指标(射门率、定位球射门次数、控球率、传球成功率和解围成功次数)和3项跑动表现指标(本方控球时跑动距离、进攻三区跑动距离和对方罚球区跑动距离)使比赛获胜概率显著提升。而向前传球次数、低强度跑距离、中强度跑距离、对方控球时跑动距离4项比赛表现指标则使获胜概率显著下降。研究表明,FIFA世界杯获胜球队在立足于防守的基础上,以防守反击和定位球作为主要进攻和得分手段,表现出与联赛球队不同的比赛策略。因此,各级球队在备战时应根据赛制和对手实力情况作出针对性的战术部署。 相似文献

中国男子篮球职业联赛(China Basketball Association),简称(CBA),是中国最高级的篮球联赛。在引进外援的20多年过程中,在最开始阶段,篮协的目的是为了帮助球队赢球,正因如此,也决定了外援的存在,从最初的目的上来看,俱乐部只是单纯的想赢球和提高观赏性。但是外援的引进对于我们联赛跟球队的发展,对于中国篮球的发展,对球员的发展,其中的利与弊值得我们思考。本研究通过文献资料法、调查法、数理统计法、逻辑分析法等研究方法对CBA引进外援对CBA联赛和球队发展的利与弊,通过研究发现:引进外援加快了CBA国际化进程,为CBA联赛注入了新理念,提高了球队整体实力,提升了联赛整体竞技水平,增强了队员的竞争意识,提高了CBA联赛的观赏性。引进外援对CBA联赛也存在消极的一面,外援薪资过高,俱乐部经济负担过重;大幅度减少了本土球员锻炼机会,影响国内后备人才的培养,语言文化存在差异,不利于球队技战术水平的发挥;外援负面事件频发,对管理体制造成威胁;外援控制了比赛胜负。通过完善现有体制,增强行政管理;加强宣传,提高影响力;制定政策依据,加强管理监督;制定政策依据,加强管理监督,极大的发挥CBA外援的优势,破解存在的诟病。 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

在当今激烈的篮球比赛中,重进攻、轻防守,特别是对无球队员的防守,没有引起足够的重视。防守能力的强弱直接影响全队的成败,尤其是对无球队员的防守能力,它是衡量一个篮球运动员防守能力高低的重要标志。文章运用文献资料研究法、观察法,对防守无球队员必须掌握的基本方法、学会在比赛中运用、注重与同伴之间的协防配合进行了分析研究,以便引起篮球界人士的重视。 相似文献

Abstract The aim of the present study was to examine the effects of changes in the number of ball contacts allowed per individual possession on the physiological, technical, and physical demands within small-sided games in elite soccer. Twenty international players (age 27.4±1.5 years, body mass 79.2±4.2 kg, height 1.81±0.02 m, velocity at [Vdot]O2max 17.4±0.8 km ·h?1, percent body fat 12.7±1.2%) performed three different small-sided game formats (i.e. 2 vs. 2; 3 vs. 3; 4 vs. 4) on three different occasions in which the number of ball contacts authorized per possession was fixed (one touch, two touches, and free play). The relative pitch per player ratio was similar for all small-sided games. The small-sided games were performed with four support players (placed around the perimeter of pitch) with instructions to keep possession of the ball. The total duration of the small-sided games was the effective time of play. The physical demands, technical requirements, heart rates, post-exercise blood lactate concentrations, and ratings of perceived exertion (RPE) were assessed. The percentages of successful passes and numbers of duels were significantly lower when the small-sided game was played with one touch (P<0.001), whereas the number of balls lost increased (P<0.001 for 2 vs. 2 and 3 vs. 3; P<0.01 for 4 vs. 4). The small-sided game played with one touch also induced increases in blood lactate concentration and RPE, as well as greater physical demands in the total distance covered in sprinting and high-intensity runs. In conclusion, the main findings of this study are that by altering the number of ball contacts authorized per possession in small-sided games, the coach can manipulate both the physical and technical demands within such games. 相似文献

ABSTRACTThis study aimed to examine the scoring mode (line goal, double goal or central goal) and age-related effects on the defensive performance of youth soccer players during 4v4 small-sided games (SSGs). Altogether, 16 male players from 2 age groups (U13, n = 8, mean age: 12.61 ± 0.65 years; U15, n = 8, 14.86 ± 0.47 years) were selected as participants. In six independent sessions, participants performed the three SSGs each during 10-min periods. Teams’ defensive performance was analysed at every instant ball possession was regained through the variables: ball-recovery type, ball-recovery sector, configuration of play and defence state. Multinomial logistic regression analysis used in this study revealed the following significant main effects of scoring mode and age: (1) line goal (vs. central goal) increased the odds of regaining possession through tackle and in the defensive midfield sector, and decreased the odds of successful interceptions; (2) double goal (vs. central goal) decreased the odds of regaining possession through turnover won and with elongated playing shapes; (3) the probability of regaining possession through interception significantly decreased with age. Moreover, as youth players move forward in age groups, teams tend to structurally evolve from elongated playing shapes to flattened shapes and, at a behavioural level, from defending in depth to more risky flattened configurations. Overall, by manipulating the scoring mode in SSGs, coaches can promote functional and coadaptive behaviours between teams not only in terms of configurations of play, but also on the pitch locations that teams explore to regain possession. 相似文献
