Abstract

In water polo, the playing style of a team is characterized by players’ tactical behaviour. The purpose of this study was to provide an analysis of offensive actions, by means of the Team Sport Assessment Procedure (TSAP) of the first four youth national teams during the 20th FINA Junior Water Polo World Championships. Twenty-nine elite youth (U20) water polo matches, involving the national teams of Greece (n=7), Serbia (n=7), Italy (n=7) and Croatia (n=8) were selected for the analysis. The TSAP included: i) two indicators of gaining possession of the ball; ii) four indicators of disposing the ball. Using these indicators, the following indices of technical performance were computed: Volume of Play (VP), Efficiency Index (EI) and Performance Score (PS). The field was divided in twelve zones. The one-way ANOVA showed no significant differences between teams for all parameters (p>0.05), except that for Offensive Balls (OB) and Successful Shots (SS) occurred in specific zones of the field: for OB significant differences were found in zone 1 (p=.019), in zone 2 (p=.014) and in zone 5 (p=.007); for SS significant differences were found in zone 1 (p=.026) and in zone 2 (p=.008). The main reason of between-teams differences could be explained by the presence of a left-hand player in the game, and by the tactical behaviour of coaches and players. The TSAP instrument could offer productive feedback to coaches to perceive the different requirements of playing and to evaluate how players understand the game.

运用团队运动评估程序(TSAP)对国际青少年水球比赛控球的技战术评价
在水球比赛中,队员的战术行为决定了球队的比赛风格。本研究的目的是利用团队运动评估程序(TSAP)对第20届国际泳联青少年水球世界锦标赛前四支国家队的进攻动作进行分析。选取希腊(n=7)、塞尔维亚(n=7)、意大利(n=7)和克罗地亚(n=8)国家队参加的29场优秀青年(U20)水球比赛进行分析。TSAP包括:i)两项控球指标;Ii)四项处理球的指标。利用这些指标,计算了以下技术性能指标:发挥量(VP)、效率指数(EI)和性能得分(PS)。这块地分为十二个区。单因素方差分析显示,除了进攻球(OB)和成功射门(SS)发生在场地的特定区域外,所有参数在球队之间均无显著差异(p>0.05):进攻球(OB)和成功射门(SS)发生在区域1 (p= 0.019),区域2 (p= 0.014)和区域5 (p= 0.07)存在显著差异;SS在1区(p= 0.026)和2区(p= 0.008)差异显著。球队之间差异的主要原因可以解释为比赛中左手球员的存在,以及教练和球员的战术行为。TSAP仪器可以为教练提供有效的反馈,以感知比赛的不同要求,并评估球员如何理解比赛。
