运用文献调研、观看比赛录像、数据统计分析、专家访谈等方法,以小球阵容解构为切入点研究了小球理念的历史演变;深入分析了勇士队死亡五小阵容的攻防特点,对勇士队小球战术体系下的进攻方式以及分项进攻效率、分项防守效率进行了研究。研究发现：勇士队转换进攻、空切和绕掩护投篮场均回合数、场均回合得分、使用频率居于联盟榜首,转换进攻、空切和绕掩护投篮成为球队进攻的主要得分手段,得分效率为联盟第一,在防守端勇士队只有转换进攻、面框单打和空切三项丢分高于联盟平均水平。未来,小球战术应用的发展趋势将会是更加注重速度和球场空间的利用以及三分球投射,空间型中锋将成为小球阵容的重要组成部分。 相似文献

通过对2004-2005赛季C BA联赛参赛球员自然状况及队伍技术状况的数据资料分析,其结果发现高大球员、特别是身高超过205C m球员的数量与球队成绩的关系密切。随着比赛水平的提高和争夺激烈程度的增加,获胜球队的防守明显加强、二分球的攻击显著增加。而所输球队的三分球攻击明显高于获胜的球队。另外,本赛季C BA联赛的防守较弱。 相似文献

新规则下排球比赛规律初探 总被引：8，自引：0，他引：8
在排球运动管理中心指导下，分析探讨了实施新规则对排球技战术发展带来的变化。研究得出：新规则实施后，一攻作用得到根本改变，防反仍占举足轻重位置，提高防反能力关系到我国排球市场的前途；比赛中各项技术得分比例发生变化，二传队员压力增大，发球作用影响深远：自由防守队员接发球和防守效果优于其他队员，我国自由防守队员接发球能力与外国队相比还有较大差距：强弱队之间比分差距缩小，比赛激烈程度加强，胜负偶然性增强；比赛时间相对缩短，比赛强度和难度提高，这对运动员提出了更高的要求；队员运动寿命延长，新人使用风险加大；我国排球技术指导思想的内涵需作适当调整与补充。 相似文献

Tennis comprises specific match situations when winning the next point is crucial. These big points can decide about a win or loss and, thus, reasonably arouse mental stress. Break points (BPs) are considered as big points and the outcome is influenced by, among a variety of other factors, the serve, which is well accepted being one of the dominant strokes in Men’s tennis. In this study, we examined the serve behaviour for male players in the Wimbledon tournament 2016 to investigate the possible impacts of presumed mental stress within the situation of BPs, and further, if winning players perform better than losing players. A total of 28.843 points were analysed and divided into BP (n?=?2.035) and non-break points – referred to as regular points (RP; n?=?26.808). 相似文献

Abstract The probability of winning games of tennis has been modelled in terms of the probability of the server winning an individual point. These models are based on the assumptions of stationarity of the point and interdependence. Stationarity is the assumption that the outcome of tennis points is not influenced by the game score at the beginning of the point. The purpose of the current investigation was to compare the outcomes of tennis points during break points and non-break points using data from 528 men's singles tennis matches from all four Grand Slam tournaments in 2008 and 2009. The retrospective probability of the receiver winning a point was 0.42 ± 0.23 during break points which was significantly greater than the 0.38 ± 0.10 during non-break points (P < 0.001). This, in turn, led to players creating significantly more break points than expected (P < 0.001) and breaking serve more frequently than expected (P < 0.001) for the points won when receiving serve. This is evidence that stationarity cannot be assumed and that models of winning tennis games may need to be enhanced to address improved receiver performance during break points. 相似文献

Shots are an essential part of the language of tennis yet little is known about the distinct types of shots in the professional game. In this study, we build a taxonomy of shots for elite tennis players using tracking data from multiple years of men’s and women’s matches at the Australian Open. Our taxonomy is constructed using model-based multi-stage functional data clustering, an unsupervised machine learning approach. Among 270,023 men’s and 178,136 women’s shots, we found 13 distinct types of serves to both the Ad and Deuce court for male players and 17 and 15 types to the Ad and Deuce for female players. More variety was found among serve returns and rally shots compared to the serve; with less variety on the backhand than forehand. There was also more overlap in the physical characteristics of groundstroke shots between male and female players than on serve. Shot type was strongly associated with winning points and shots in the highest speed and lowest net clearance categories tended to be the most effective. This data-driven dictionary of shots provides a framework for analysis of elite player performance, characterizing playing style, and designing more representative practice. 相似文献

AbstractThe purpose of the present study was to identify which game-related statistics discriminate winning and losing teams in men’s and women’s elite wheelchair basketball. The sample comprised all the games played during the Beijing Paralympics 2008 and the World Wheelchair Basketball Championship 2010. The game-related statistics from the official box scores were gathered and data were analysed in 2 groups: balanced games (final score differences ≤12 points) and unbalanced games (final score differences >13 points). Discriminant analysis allowed identifying the successful 2-point field-goals and free-throws, the unsuccessful 3-point field-goals and free-throws, the assists and fouls received as discriminant statistics between winning and losing teams in men’s balanced games. In women’s games, the teams were discriminated only by the successful 2-point field-goals. Linear regression analysis showed that the quality of opposition had great effects in final point differential. The field-goals percentage and free-throws rate were the most important factors in men’s games, and field-goals percentage and offensive rebounding percentage in women’s games. The identified trends allow improving game understanding and helping wheelchair basketball coaches to plan accurate practice sessions and, ultimately, deciding better in competition. 相似文献
