This study explores the influence of sideout failure on performance in the next sideout in beach volleyball. The sample comprises 965 elite matches in the FIVB World Series 2012-2016 and in the Olympic Games 2012/2016 including 28,974 sideout sequences (12,755 for men and 16,219 for women). A sideout sequence consists of two sideouts by the same player during the same set in a timeframe of four rallies. The first sideout in this sequence is referred to as the previous sideout and the second sideout as the next sideout. After misses, -tests indicate a significantly higher technique alternation rate (from spike to shot or vice versa) in the next sideouts for both men (+32.7%) and women (+40.4%) than the next sideouts after hits. After shot misses, the share of shots in the next sideouts was -12.9% lower for men and -8.3% lower for women than the next sideouts after shot hits. After spike misses, the share of shots in the next sideouts by female players was +5.5% significantly higher, and shot hit rate was -6.5% lower than the next sideouts after spike hits. These findings support the belief that tactical decisions and performance in top-level beach volleyball are influenced by failure in the previous sideouts. They might support coaches and players when analyzing matches and developing game strategies.
本研究探讨了沙滩排球中接发球失误对下一次接发球时表现的影响。样本包括2012 - 2016年国际排联世界系列赛和2012/2016年奥运会的965场精英比赛,其中包含28974个接发球序列(男子12755个,女子16219个)。一个接发球序列由同一名球员在同一局比赛中四个回合的时间范围内的两次接发球组成。该序列中的第一次接发球称为前一次接发球,第二次接发球称为下一次接发球。失误后,t检验表明,男子(+32.7%)和女子(+40.4%)在下一次接发球时的技术交替率(从扣球到击球或反之)显著高于击球后的下一次接发球。发球失误后,男子在下一次接发球时的发球比例比发球得分后的下一次接发球低12.9%,女子低8.3%。扣球失误后,女球员在下一次接发球时的击球比例显著高出5.5%,扣球命中率比扣球得分后的下一次接发球低6.5%。这些发现支持了这样一种观点,即顶级沙滩排球中的战术决策和表现会受到前一次接发球失误的影响。在分析比赛和制定比赛策略时,这些发现可能会对教练和球员有所帮助。
