主要运用临场观察统计法,对2002—2003年冬训中国内优秀少年足球守门员防守技术运用情况进行统计与分析,为进一步提高我国少年足球守门员技术水平提供参考依据。统计研究表明,判断选位意识差与反应能力低是2002—2003年冬训中少年守门员防守技术失误的主要原因,技术粗糙以及缺乏自信等导致少年守门员接、扑球技术不稳固,对抗条件下难以有效发挥位置优势,强干扰情况时出击失误增多。增强自信心、提高战术意识和专项身体素质水平、重视反应训练和提高接球动作质量要求应是提高少年守门员技术水平的重中之重。 相似文献

主要运用观察统计与逻辑分析方法，对目前国内优秀U—17少年守门员接扑球技术运用情况及存在问题分析研究。结果表明，U—17少年守门员接扑球技术运用中，主要问题是判断选位差与反应能力不足，接扑基本技术欠扎实，心理稳定性不够，临场比赛接扑球技术运用成功率低，失球数多。建议训练中要努力促使少年守门员掌握全面的基本技术和具备准确的判断能力，加强意识与心理素质的引导和培养，训练与实战紧密结合，严格技术动作质量要求，提高专项素质水平，促进少年守门员动作技能的完善与稳定，切实改变比赛中守门员技术不过硬的现状。 相似文献

"不依赖射手"和"依赖射手"策略是守门员判断点球射门方向时的两个基本认知策略,其选择在很大程度上取决于出击前守门员能否从射手身上获得与之相关的视觉反馈信息.通过分析获得这些信息的可能性,推断出预先决定出击方向,集中注意力预测出击开始时间和球的飞行轨道是守门员应对点球时的最佳认知策略.为了进一步揭示优秀足球守门员应对点球的行动策略,收集了422个点球录像,对与守门员点球防守行动策略有关的内容进行了观测统计.结果表明,优秀足球守门员通常选择球门的左下侧、右下侧和中间3个方向为出击方向,主要防守球门的左(右)下半部,及早出击、正确判断射门方向和选择合理的防守区域是优秀足球守门员扑点球成功的关键. 相似文献

第17届世界杯足球决赛亚洲队守门员防守技术的统计分析 总被引：4，自引：0，他引：4
运用观察与统计、比较分析等方法，对第17后世界杯足球赛决赛阶段亚洲球队守门员主要防守技术的运用情况进行统计归类与比较分析。结果表明，本届世界杯赛亚洲守门员总体的水平发挥，韩国队表现较佳，日本队其次，中国、沙特表现欠佳。中国、沙特守门员位置技术的不稳定与队伍成绩相吻合。对角球及边路传中进攻打法的防守能力有待提高，缺乏经验，判断反应与选位能力的不足，导致亚洲守门员自身技术运用失误增多，对抗中难以发挥守门员的位置优势，强干扰状态下技术发挥的税定性差，关键场次的失球制约了队伍成绩的提高。我国守门员训练要在丰富大赛经验，提高比赛意识水平，加强心理培养，全面提升训练质量的基础上，进一步提高认识水平，以适应高水平强对抗的国际大赛的需要。 相似文献

守门员要扩大防守的范围,减轻防守的压力,必须具备善于出击的能力。在比赛中,往往由于守门员出击不及时或是不应出击而出击,造成失球的现象。论述了守门员出击的各种时机、不应出击的情况。提高守门员善于出击的能力,应着重在智力训练和良好心理素质培养等方面下功夫 相似文献

Abstract Previous research has shown that young male soccer players who are born early in a cohort are overrepresented on elite soccer teams. Selection advantages such as this have been termed ‘relative age effects’ (RAEs). Few studies have examined RAEs in elite women's youth soccer. Therefore, the aim of this study is to investigate the occurrence of RAEs in the Fédération Internationale de Football Association (FIFA) U-17 Women's World Cup competition and their link to playing positions. In the entire cohort of 672 players, we found significant RAEs in the geographical zones of Europe and North and Central America, no RAEs in the zones of Asia, Oceania, and South America, and significant inverse RAEs in the zone of Africa. Additionally, significant RAEs were found for goalkeepers and defenders from Europe and North and Central America. Inverse RAEs occurred for African goalkeepers, defenders, and strikers. Goalkeepers of all zones were significantly taller than players of all other playing positions. The results of this study show that remarkable RAEs do exist at elite women's youth soccer. Similar to men's soccer, there is a bias toward the inclusion of relatively older players, and a link between RAEs and playing positions. 相似文献

The aim of this study was to examine whether perceptual variables can provide informational constraints for the goalkeepers to intercept the ball successfully in 1v1 dyads. Video images of 42 actions (1v1 in direct shots) were selected randomly from different matches and divided into conceded goals (n = 20) and saved actions (n = 22) to investigate interceptive actions of 20 goalkeepers in the English Premier League in season 2013–2014. Time to Contact (TTC) of the closing distance gap between shooter and goalkeeper was obtained by digitising actions in the 18-yard penalty box. Statistical analyses revealed that, in sequences of play resulting in an intercepted shot at goal, goalkeepers closed down outfield players in the X axis, whereas when a goal was conceded, there was a significantly delayed movement by goalkeepers toward the shooters in this plane. The results of canonical correlations showed that a decreasing distance between a shooter and goalkeeper, and accompanied reduction in relative interpersonal velocity followed a temporal pattern. Findings of this study showed how perception of key informational constraints on dyadic system relations, such as TTC, interpersonal distance and relative velocity, constrain elite goalkeepers’ interceptive actions, playing an important role in successful performance. 相似文献

Visual search, anticipation and expertise in soccer goalkeepers 总被引：3，自引：3，他引：0
We used a novel methodological approach to examine skill-based differences in anticipation and visual search behaviour during the penalty kick in soccer. Expert and novice goalkeepers were required to move a joystick in response to penalty kicks presented on film. The proportion of penalties saved was assessed, as well as the frequency and time of initiation of joystick corrections. Visual search behaviour was examined using an eye movement registration system. Expert goalkeepers were generally more accurate in predicting the direction of the penalty kick, waited longer before initiating a response and made fewer corrective movements with the joystick. The expert goalkeepers used a more efficient search strategy involving fewer fixations of longer duration to less disparate areas of the display. The novices spent longer fixating on the trunk, arms and hips, whereas the experts found the kicking leg, non-kicking leg and ball areas to be more informative, particularly as the moment of foot-ball contact approached. No differences in visual search behaviour were observed between successful and unsuccessful penalties. The results have implications for improving anticipation skill at penalty kicks. 相似文献
