In beach volleyball the setter has the opportunity to give her or his hitter a "call". The call intends that the setter suggests to her or his partner where to place the attack in the opponent's court. The effectiveness of a call is still unknown. We investigated the women's and men's Swiss National Beach Volleyball Championships in 2011 and analyzed 2185 attacks. We found large differences between female and male players. While men called in only 38.4% of attacks, women used calls in 85.5% of attacks. If the male players followed a given call, 63% of the attacks were successful. The success rate of attacks without any call was 55.8% and 47.6% when the call was ignored. These differences were not significant (χ(2)(2) = 4.55, p = 0.103). In women's beach volleyball, the rate of successful attacks was 61.5% when a call was followed, 35% for attacks without a call, and 42.6% when a call was ignored. The differences were highly significant (χ(2)(2) = 23.42, p < 0.0005). Taking into account the findings of the present study, we suggested that the call was effective in women's beach volleyball, while its effect in men's game was unclear. Considering the quality of calls we indicate that there is a significant potential to increase the effectiveness of a call.
在沙滩排球中，二传手有机会给她或他的扣球队员“呼叫”。这个呼叫的目的是二传手建议她或他的搭档在对方场地的哪个位置发起攻击。呼叫的有效性尚不清楚。我们调查了 2011 年瑞士国家沙滩排球锦标赛的男女比赛，并分析了 2185 次进攻。我们发现男女球员之间存在很大差异。男性球员在只有 38.4%的进攻中使用了呼叫，而女性球员在 85.5%的进攻中使用了呼叫。如果男性球员遵循给定的呼叫，那么 63%的攻击是成功的。没有任何呼叫的攻击成功率为 55.8%，而忽略呼叫的攻击成功率为 47.6%。这些差异并不显著（χ²(2)=4.55，p=0.103）。在女子沙滩排球中，当遵循呼叫时，成功攻击的比率为 61.5%，没有呼叫时为 35%，忽略呼叫时为 42.6%。这些差异具有高度显著性（χ²(2)=23.42，p<0.0005）。考虑到本研究的发现，我们认为呼叫在女子沙滩排球中是有效的，而在男子比赛中的效果尚不清楚。考虑到呼叫的质量，我们表明有很大的潜力可以提高呼叫的有效性。
