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

Abstract The aim of this large-scale study of elite professional football teams was to identify the independent and interactive effects of game location and final outcome on football game-related statistics according to the zone of the pitch in which they occurred. The sample consisted of 1900 games played over five seasons (from 2003–2004 to 2007–2008) of the Spanish Professional Football League. Factor analysis with principal components was applied to the game-related statistics recorded from the games, which limited the analysis to four factors (Factor 1: Turnovers in zone 5.2 and Crosses in zone 4; Factor 2: Goals and shots in zone 5.1, Turnovers in zone 4, and Ball recover in zone 2; Factor 3: Goals and shots in zone 5.2; and Factor 4: Turnovers in zone 5.1). Zone 2 was between the defensive semi-circle area and midfield circle, Zone 4 was between the midfield circle and offensive semi-circle area, Zone 5.1 was the offensive goal area, and Zone 5.2 was the offensive small area). A mixed linear model was applied to identify the effects of game location and final outcome on the previously identified factors. Game location and final outcome main effects were identified for all factors, with home and winning teams having better values. The interaction Location×Outcome was only significant for Factor 4 (Turnovers in zone 5.1). When playing at home, teams had higher frequencies for all analysed variables, probably resulting from home advantage factors such as facility familiarity and/or crowd. Additionally, winning teams’ exhibited different and consistent profiles from drawing and losing teams, mainly discriminated by their ability to recover the ball in Zone 2 and to organize the offence using penetrative passes to Zones 5.2 and 5.1 to increase the number of shots and consequently goals. The trends identified may provide important information for modelling high-level performances. 相似文献

AbstractThe purpose of this study was to explore football game-related statistics during a competition, using principal component and cluster analyses to determine if it is possible to distinguish the winning teams from the drawing and losing ones. We collected the game-related statistics of the group phase matches of the 2006 World Cup and organised them into a matrix. The principal components of the covariance matrix were calculated. The scores of the first and second components were used to represent the new data, and cluster analysis was applied to separate the elements in two groups (G1 and G2). To analyse the degree of separation between the groups, we calculated the Silhouette Coefficient for each group. Finally, we checked if the winning teams were classified into the same group. The Silhouette Coefficients found for G1 and G2 were 0.54 and 0.55, respectively. Results showed that 70.3% of the winning teams were classified into the same group (G1). Similarly, 67.8% of the drawing and losing teams were classified in G2. This study presented a different way to analyse game-related statistics that allowed the multivariate differences to be shown between successful and unsuccessful teams. 相似文献

Abstract The aim of this study was to identify within-season differences in basketball players' game-related statistics according to team quality and playing time. The sample comprised 5309 records from 198 players in the Spanish professional basketball league (2007–2008). Factor analysis with principal components was applied to the game-related statistics gathered from the official box-scores, which limited the analysis to five factors (free-throws, 2-point field-goals, 3-point field-goals, passes, and errors) and two variables (defensive and offensive rebounds). A two-step cluster analysis classified the teams as stronger (69±8 winning percentage), intermediate (43±5 winning percentage), and weaker teams (32±5 winning percentage); individual players were classified based on playing time as important players (28±4 min) or less important players (16±4 min). Seasonal variation was analysed monthly in eight periods. A mixed linear model was applied to identify the effects of team quality and playing time within the months of the season on the previously identified factors and game-related statistics. No significant effect of season period was observed. A team quality effect was identified, with stronger teams being superior in terms of 2-point field-goals and passes. The weaker teams were the worst at defensive rebounding (stronger teams: 0.17±0.05; intermediate teams: 0.17±0.06; weaker teams: 0.15±0.03; P=0.001). While playing time was significant in almost all variables, errors were the most important factor when contrasting important and less important players, with fewer errors being made by important players. The trends identified can help coaches and players to create performance profiles according to team quality and playing time. However, these performance profiles appear to be independent of season period. 相似文献

Abstract The aim of the present study was to identify the game-related statistics that discriminate between season-long successful and unsuccessful basketball teams participating in the Spanish Basketball League (LEB1). The sample included all 145 average records per season from the 870 games played between the 2000–2001 and the 2005–2006 regular seasons. The following game-related statistics were gathered from the official box scores of the Spanish Basketball Federation: 2- and 3-point field-goal attempts (both successful and unsuccessful), free-throws (both successful and unsuccessful), defensive and offensive rebounds, assists, steals, turnovers, blocks (both made and received), and fouls (both committed and received). To control for season variability, all results were normalized to minutes played each season and then converted to z-scores. The results allowed discrimination between best and worst teams’ performances through the following game-related statistics: assists (SC=0.47), steals (SC=0.34), and blocks (SC=0.30). The function obtained correctly classified 82.4% of the cases. In conclusion, season-long performance may be supported by players’ and teams’ passing skills and defensive preparation. 相似文献

探索不同赛制下比赛表现指标对比赛结果产生的影响,选取2018年俄罗斯世界杯59场、118组技战术表现和跑动表现指标作为自变量,比赛胜、负作为因变量。运用K型聚类分析,对比分均衡比赛进行界定。根据比赛控球率的不同对比赛表现指标进行标准化处理。运用数据级数推断法界定各自个变量增加2个标准差对比赛获胜概率带来的变化。研究结果:1)在所有比赛中,9项技战术表现指标(射门次数、射正次数、射正率、定位球射门次数、突破进入罚球区次数、控球率、传球成功率、解围成功次数和防守反击次数)和3项跑动表现指标(本方控球时跑动距离、进攻三区跑动距离和对方罚球区跑动距离)使比赛获胜概率显著提升。对方控球时跑动距离则使获胜概率显著下降;2)在比分均衡比赛中,5项技战术表现指标(射门率、定位球射门次数、控球率、传球成功率和解围成功次数)和3项跑动表现指标(本方控球时跑动距离、进攻三区跑动距离和对方罚球区跑动距离)使比赛获胜概率显著提升。而向前传球次数、低强度跑距离、中强度跑距离、对方控球时跑动距离4项比赛表现指标则使获胜概率显著下降。研究表明,FIFA世界杯获胜球队在立足于防守的基础上,以防守反击和定位球作为主要进攻和得分手段,表现出与联赛球队不同的比赛策略。因此,各级球队在备战时应根据赛制和对手实力情况作出针对性的战术部署。 相似文献

通过观察比赛录像、收集有关网站资料、查阅相关文献,运用归纳、整理、对比分析等方法对参加第29届奥运会女子足球比赛的中国队和前四强球队进行了技术统计,且对统计数据反映出的中国女足现状进行分析对比。结果表明：中国女足在比赛中有着顽强的拼搏精神,但是与前四强球队之间还有较明显的差距,表现在心理素质不够稳定,进攻欲望不强烈,对足球比赛中的攻守转化需要进一步的加强。 相似文献
