In the general population, estimates of left-foot preference are around 20%. In soccer, specific tasks create positional demands, requiring 40% of the players to be left-footed. Whether and how this is related to the selection of players is unknown. To examine the successive selection of soccer players for Dutch national youth teams in relation to foot preference, 280 youth players (age = 16.2 ± 1.08 years) were monitored from the U16 through the U19 teams over the last 5 years. No difference in successive selection between left- and right-footed players was found (p < 0.05). Regardless of foot preference, more than 50% of the selected players were deselected out of a national youth team after 2 years. On average, 31% of the national youth players were left-footed, which is higher than expected, based on population estimates (χ (1) = 37.49, p < 0.001, w = 0.27). However, there was an under-representation of left-footed players, based on expected positional demands (i.e., attack, midfield, defence) (χ (1) = 16.83, p < 0.001, w = 0.18). The conclusion is that left-foot preference increases the probability of selection in Dutch national youth soccer teams.
在普通人群中,左脚偏好的比例估计约为20%。在足球领域,特定任务产生了位置需求,要求40%的球员为左脚球员。这是否以及如何与球员选拔相关尚不清楚。为了研究荷兰国家青年队足球运动员的连续选拔与脚偏好的关系,在过去5年中对280名青年球员(年龄 = 16.2 ± 1.08岁)从U16到U19球队进行了监测。左脚和右脚球员在连续选拔上没有差异(p < 0.05)。无论脚偏好如何,超过50%的入选球员在两年后被从国家青年队中淘汰。平均而言,国家青年队球员中有31%是左脚球员,这高于基于总体估计的预期(χ(1) = 37.49,p < 0.001,w = 0.27)。然而,基于预期的位置需求(即进攻、中场、防守),左脚球员的比例不足(χ(1) = 16.83,p < 0.001,w = 0.18)。结论是,左脚偏好增加了入选荷兰国家青年足球队的概率。
