运用录像观察等研究方法,对第18届世界杯足球赛的64场比赛,分别从前场、中场、后场三个不同区域的控球时间、射门次数、射门成功率、进球数等方面做了系统的分析.力求以控球时间为切人点,探讨影响比赛胜负关系的相关因素.结果显示:前场控球时间与射门次数有非常显著的正相关性,与射门成功率有显著的负相关性,与进球数没有显著的相关性,前场控球时间与本方失球数有显著的负相关性;中场控球时间与射门次数、进攻效率、进球数都有非常显著的正相关性,与射门成功率没有显著的相关性;后场控球时间与中、前场控球时间呈显著的负相关性;而与其他因素没有显著的相关性. 相似文献

在现代篮球比赛中，激烈程度日益增强，因而使得比赛中的犯规次数急剧增加，罚球次数随之增加。罚球命中率的高低往往在实力相当的比赛中起关键作用。而决定罚球命中率不仅有技术因素，罚球时的心理状态也是重要的因素。经过对部分市区少体校男女篮球运动员在罚球时心理状态进行调查，发现有83％的运动员罚球的命中率受到心理因素的影响，且73％的运动员认为自己在比赛时罚球的命中率低于平时的训练水平。本通过对比赛中罚球失误的心理分析，提出罚球时的心理调控措施与训练方法。 相似文献

篮球运动是同场竞技类集体运动项目,比赛时间长、高速度、高强度的对抗是该项目的特点,而且运动员的竞技状态呈波峰形发展,随着比赛时间的延长运动员的体力消耗增大,技战术的发挥下降。本文对第2 9届奥运会八强队伍所有比赛场次的运动员的出场次数、平均上场时间、比赛中全队换人次数与队员个人上场次数等进行统计,分析影响八强队员上场时间的因素。研究结果表明:第2 9届届奥运会男篮比赛中取得成绩越好的队伍,其队员参赛率越高,突出了队员的个人能力强,队伍的整体实力高,分析认为影响男篮八强队员上场时间受运动员的个人竞技能力、战术、场上比分、个人犯规次数、运动员场上位置和伤病等因素的影响。 相似文献

根据选手所处的不同状态，乒乓球比赛的节奏可以分为北赛状态下的节奏和非比赛状态下的节奏，前者是选手实际击球时的节奏，后者则反映了选手在局间休息、比赛暂停等间歇时段下的情形，在任何一场乒乓球比赛中，这两种节奏都处于不断的相互交替之中，只不过随着条件的不同，它们交替的次数和频率也有所差异。 相似文献

It has been suggested that individuals may use heuristic methods of reasoning and rely on schemata when a quick decision is necessary. Accordingly, it is possible that decisions made by sport officials may be influenced by prior knowledge they have about teams they are officiating. The aim of the present study was to determine whether sport officials are more likely to penalize individuals who participate in a team with an aggressive reputation. In a balanced design, 38 football referees were randomly assigned to either an experimental or control group and were presented with the same 50 video clips of incidents from football games, all involving a team in a blue strip ('blue team'). The incidents were categorized before the study by five experienced referees into fouls committed both by, and against, the blue team, where all participants agreed that a foul had been committed (certain incidents), disagreed it was a foul (uncertain incidents) or agreed that there was no foul (innocuous incidents). Both groups received written instructions before the task; in addition, the experimental group was informed that the blue team present in all of the clips had a reputation for foul and aggressive play. For each incident, the participants were required to indicate what action they would engage in if refereeing the game. Although there was no difference in the number of decisions made, the experimental group awarded significantly more red and yellow cards against the blue team both overall and for the 'certain' incidents. It is suggested that prior knowledge may impact referees' behaviour in a laboratory setting, although future research should explore whether a similar effect is observed in the behaviour of referees during football matches. 相似文献

Objectives: Slow-motion replays of foul play situations are now used in the education and training of sports officials. We investigated the impact of video speed on the decision-making process of association football referees and how this interacted with expertise. Methods: Three different groups of referees, varying in level of expertise, assessed video clips from an in-game perspective. Video clips represented corner kick and open play situations in which a foul occurred or not. For these foul/no foul situations, the referees had to make a technical (no foul; indirect free kick; direct free kick; or penalty kick) and a disciplinary decision (no card; yellow card; or red card), under both slow-motion and real-time viewing conditions. Accuracy scores were determined by comparing participant’s responses with the decisions of an expert panel. Results: Significant differences were observed across groups for foul/no foul situations, suggesting that the experts were able to process the available information more effectively than their less expert colleagues. The accuracy scores for the technical decision were higher in slow motion (67%) compared to a real-time viewing condition (56%), particularly for corner kick situations. No differences were found between real time and slow motion for the disciplinary decision. Conclusions: Slow-motion footage results in higher accuracy scores for complex technical decisions. These findings have implications for the use of slow-motion replays in the decision-making process of referees. 相似文献

Abstract In association football, two similar but arguably different refereeing roles are required, those of the referee and assistant referee. Role specificity was investigated with a foul play assessment task and an offside decision-making task. Deliberate practice was investigated to account for role-specific differences. First, role specificity was clearly observed. Second, years of officiating, hours of practice per week, and number of matches officiated were each positively correlated with skill. The results support role specificity in association football refereeing. Further research should help to create role-specific perception and decision-making training programmes both for referees and assistant referees. 相似文献
