Abstract

This study aimed to identify the effects of playing with additional individual (IND), collective (COL) or individual-collective (MIX) variability on youth football players' performance during small-sided games. Twelve youth football players (U17, age = 16.1 ± 0.9 years) played a goalkeeper (Gk) + 6 outfield players a-side (Gk+6vs6+Gk) under four conditions: (i) playing in the 1:2:3:1 formation without any other rule (control condition, CTR); (ii) 1:2:3:1 formation with additional body restrictions changing each minute (individual condition, IND); (iii) using different tactical formations modified each minute (collective condition, COL; (iv) using different tactical formations and body restrictions varied each minute (individual-collective condition, MIX). Generally, there were similar behaviours across conditions, especially for the CTR and the MIX. Nevertheless, the CTR condition presented moderate higher values in the lateral direction (p ≤ .05), while also higher longitudinal synchronization compared to the IND (p ≤ .05). The COL condition presented higher spatial exploration (p ≤ .05), which may justify the higher values for distance covered while running and sprinting (p ≤ .05). Overall, coaches may use the IND condition to refine players' technical actions, while the COL condition to develop players' ability to perform in different playing positions and team structures.

个人和集体变异性对青少年球员在小型足球比赛中运动行为的影响。

本研究旨在确定额外的个人（IND）、集体（COL）或个人-集体（MIX）变异性对青少年足球运动员在小型比赛中表现的影响。12名青年足球运动员（U17，年龄=16.1±0.9岁）在四种条件下与守门员（Gk）+6名外场球员（Gk+6vs6+Gk）比赛：（i）在没有任何其他规则的情况下以1:2:3:1的队形比赛（控制条件，CTR）；（ii）1:2:3:1的队形，每分钟改变额外的身体限制（个人情况，IND）；（iii）使用每分钟修改的不同战术队形（集体条件，COL；（iv）使用不同的战术队形，每分钟改变身体限制（个人集体条件，MIX）。一般来说，不同条件下都有类似的行为，尤其是CTR和MIX。然而，与IND（p≤.05）相比，CTR条件在横向方向上表现出中等较高的值（p≤0.05），同时也表现出较高的纵向同步性。COL条件表现出更高的空间探索性（p≤005），这可能证明了跑步和短跑时所覆盖距离的较高值（p≤.05）。总体而言，教练可以使用IND条件来完善球员的技术动作，而COL条件则可以培养球员在不同比赛位置和团队结构中的表现能力。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
