Technical-tactical performance profile of the block and dig according to competition category in men's volleyball

Abstract The aim of this study was to analyse the technical-tactical performance profile of blocking and court defence actions for various age groups and categories of competition in men's volleyball. The sample comprised 16,454 blocks and 8,321 digs performed in 299 sets in several categories of competition (from U-14 to Olympic Games). A descriptive and correlational inter- and intra-group observational design was used. The variables studied were: category of competition, opponent's spike tempo, and block and dig performance. The results showed a significant increase in the percentage of blocks and digs derived from fast attacks and a significant improvement in performance of these actions to counteract slow attacks. Thus, improving in blocking and digging performance was observed at higher categories when the attack is performed slowly. This paper discusses various reasons for the evolution in defensive performance and the effects on the training process for various categories of competition in volleyball.

摘要 本研究旨在分析男子排球不同年龄组与赛事类别中拦网与球场防守动作的技战术表现特征。研究样本涵盖299局比赛中完成的16454次拦网与8321次救球，赛事类别覆盖U-14至奥林匹克运动会多个层级。本研究采用描述性与相关性的组间及组内观察性研究设计。本次研究考察的变量包括：赛事类别、对手扣球节奏，以及拦网与救球表现。研究结果显示，源自快攻的拦网与救球占比显著提升，且针对慢攻的拦救动作表现亦得到显著改善。据此可见，在赛事层级更高的组别中，当进攻节奏较慢时，拦网与救球表现均有所提升。本文探讨了排球不同赛事类别中防守表现演进的多项成因，及其对训练流程的影响。
