Abstract

ABSTRACT The aim of the study was to quantify the individual player area (IPA) that emerges during football matches at youth levels, considering different numerical relations and pitch zones. Two hundred and twenty-eight players, divided by U15, U17 and U19, participated in the study. Jonckheete-Terpstra and Kruskal Wallis nonparametric tests were used to compare the IPA according to variations in players’ age, numerical relations and pitch zones considered for analysis. All ages and numerical relation results revealed the highest IPA in the zones closer to the goal and were lower in the middle of the pitch. For 3 × 3 to 10 × 10 numerical relations, the IPA was higher in the U15 and lower in the U17. The greater differences between the age groups concerned numerical relations of 6 × 6 to 10 × 10 (p ≤ 0.001). The effect size was moderate between the U15 and U17 in numerical relations of 8 × 8 to 10 × 10. Results suggest that the manipulation of IPA during training sessions should respect players’ age and be adjusted considering the numerical relation and the tactical purpose of coaches.

青少年足球比赛中个人球员区域的变化：球员年龄、数字关系和球场区域变化的影响

本研究的目的是在考虑不同的数值关系和球场区域的情况下，量化青少年足球比赛中出现的个人球员区域(IPA)。按照U15、U17和U19分组，共有228名球员参与了这项研究。采用Jonckheete-Terpstra和Kruskal Wallis非参数检验，根据球员年龄、数值关系和考虑分析的球场区域的变化来比较IPA。所有年龄和数值关系结果都显示，靠近球门的区域IPA最高，而球场中部的区域IPA较低。在3 × 3 ~ 10 × 10数值关系下，U15的IPA较高，U17的IPA较低。年龄组间差异较大的数值关系为6 × 6 ~ 10 × 10 (p≤0.001)。U15和U17的效应量在8 × 8 ~ 10 × 10之间呈中等水平。结果表明，训练过程中IPA的操作应尊重球员的年龄，并考虑数值关系和教练的战术目的进行调整。
