【摘要】 拦网技术是排球运动的主要技术之一,随着排球运动的不断发展以及排球规则的不断演变,拦网技术在在排球的防反体系中已经不再是单一的防守第一防线,也成为了一项重要的得分手段。拦网水平已成为球队强弱的重要指标,拦网的成功率也是影响比赛胜负的重要因素。拦网水平的提高是促进中国男子排球重新崛起的重要因素。本研究以国家男子排球队拦网移动距离为研究对象,选用Dartfish软件对国家队主要队员的拦网距离进行测量,确定了脚步移动距离、实际移动距离和最佳移动距离三个测量指标,并对测量结果进行分析研究,得出以下结论：1、本研究对拦网移动环节的移动距离的概念进行了界定,确立了脚步移动距离、实际移动距离和最佳移动距离的概念,并利用Dartfish软件对拦网移动距离进行测量,构建了脚步移动距离、实际移动距离和最佳移动距离的测量方法和手段,为拦网移动环节移动距离的研究提供理论和数据支持。2、研究中国国家男子排球队主要队员拦网情况得出：队员整体拦网效果不佳,仅CP略好,有效拦网为36.7%。通过对拦网移动距离的分析,认为主攻队员SQ、ZWJ和CP对进攻球路线、方向的判断出现了偏差,致使拦网失败；副攻队员BHM、LCM和YDW由于拦网时的站位以及脚步移动速度和移动路程,致使拦网起跳点与进攻球的垂直点距离较大,导致拦网效果不佳；二传与接应队员LRM和JK主要由于对进攻球路线和方向判断的偏差致使拦网效果不佳。3、研究中国国家男子排球队各位置拦网情况得出：球队整体拦网效果不佳,有效拦网仅为23.8%,主攻最好,副攻最差。有效拦网中,拦起比例最高；无效拦网中,未拦比例最大。分析拦网移动距离得出,主攻与二传和接应队员拦网效果不佳主要是对进攻球的路线和方向判断的失误,而非拦网脚步移动距离的原因；而副攻队员拦网失败是因为脚步移动距离不足,致使拦网起跳点与进攻球垂直点距离偏大所造成的,其与副攻队员的移动距离和移动速度密切相关。更多还原

【Abstract】 Blocking technology is one of the main techniques of volleyball, volleyball as well as the continuous development of the evolving rules of volleyball, volleyball blocking technology in the anti-anti-system is no longer a single defense first line of defense, has become a of important score means. Block level has become an important indicator of the strength of the team; the success rate of blocking is also an important factor affecting the outcome of the game. In recent years, with the rapid development of world volleyball, volleyball is also constantly improving the technology innovation. After the Olympics there are statistics show that Chinese men and the gap between the world’s best volleyball in descending order are serving, blocking, blocking anti with, attacking, blocking a higher level is to promote the re-emergence of China’s major men’s volleyball factors. In this study, Chinese men’s volleyball block distance for the study, use Dartfish software for Chinese men’s volleyball players’ block away from the main measure to determine the pace of moving away from the actual distance and move away from three best measure, and measurement results of analysis, the following conclusions:1、 The mobile part of the books of blocking the movement of the concept of distance has been defined and established distance pace, distance and actual distance of the best concepts, and Dartfish software to block the use of distance measurements, constructed from the pace of moving, the actual distance and the best distance measurement method and means for blocking the mobile part of the research moving from theory and data support.2、 Mainly through the Chinese men’s volleyball team block analysis of the situation, draw: Players overall blocking ineffective, Chen Ping, only slightly better, the effective blocking of36.7%. The reasons for poor team block, block by moving away from its analysis that the main players Shen Qiong, Chen Ping Chung King and the ball on the offensive line, the direction of the judge erred, leading to block failure, and Shen Qiong and Chen level should also increase the body ability to adjust,论文随即验证编号: BT633011343057v and Chung King and the block shoul d increase the pace of mobility；Fu Gong members while Hong Min，Liang hun Long and David at the station as well as block at the speed and footwork moves away, resulting in blocking off point the vertical distance the ball attaeking the larger, resulting in ineffective blocking, while on the offensive side of Hong Min should strengthen the ability to judge the direction of the ball; second pass with the collusion of members and Jiang Kun Li Runming mainly due to the ball on the offensive line and determine the direction of the bias resulting block ineffective, Li Runming which should be strengthened more ability to adjust the body to block movement for greater distance, improved blocking effect.3.Mainly through the Chinese men’s volleyball team block of the overall analysis resulted in: Chinese men’s volleyball as a whole block ineffective, effective blocking of only23.8%, of which the main block the best, worst Fugong block. Effective block, the highest proportion since stopped; invalid block, the largest proportion is not stopped. Through the analysis of block moving distande, and the collusinon of the main players with the second pass blocking is mainly ineffective the ball on the offensive line and d etermine the direction of the errors, rather than blocking the pace of moving from the reasons for that; and Fu Gong members failed because the pace of moving block distance of less. resulting in blocking the vertical take-off point and attack the ball caused by the distance is too large, its members and Fu Gong movement distance and speed are closely related.论文随机验证编号:BT633011343057更多还原
