Abstract

ABSTRACT Kicking powerfully and accurately is essential in soccer, and players who kick proficiently with both feet are highly sought after. Assessing performance in youth players is often confounded by more physically developed players outperforming their smaller peers. To alleviate such bias, we present a testing protocol and normative data developed with an elite Brazilian soccer academy that controls for players’ age and size to assess kick performance with both feet. We measured kick speed and kick accuracy of 178 players and recorded their age (10–20 years), height, and mass. Combining age, height, and mass into an age and size index (ASI), we developed equations describing the relationship between ASI and performance. To determine the underlying predictors of performance, we also measured sprint ability and soccer-specific motor control of each foot with ball dribbling tasks. Kicking speed with the dominant foot was predicted by ASI, sprint speed, and motor control of the nondominant foot, while kicking speed with the nondominant foot was predicted by ASI and motor control of the nondominant foot. Kick accuracy with each foot was predicted by ASI and motor control of the corresponding foot. To improve kicking performance, we suggest training programs focus on motor control.

精英青少年足球运动员的年龄和体型校正踢球速度和准确性
踢得有力、准确是足球运动中的关键,而双脚踢得熟练的球员则备受追捧。在评估青年球员的表现时,往往会被身体发育得更好的球员表现得比同龄人差而感到困惑。为了缓解这种偏见,我们提出了一个与巴西一所精英足球学院共同开发的测试方案和规范性数据,该学院控制球员的年龄和体型,以评估双脚踢球的表现。我们测量了178名球员的踢球速度和踢球精度,并记录了他们的年龄(10-20岁)、身高和体重。将年龄、身高和质量组合成年龄和体型指数(ASI),我们开发了描述ASI与表现之间关系的方程。为了确定表现的潜在预测因素,我们还测量了运球任务中每只脚的短跑能力和足球专项运动控制能力。支配脚的踢球速度由ASI、短跑速度和非支配脚的运动控制预测,而支配脚的踢腿速度则由ASI和非支配足的运动控制来预测。每只脚的踢球精度通过ASI和相应脚的运动控制来预测。为了提高踢腿的表现,我们建议训练项目侧重于运动控制。
