| 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... |
