The aim of this study was to identify how positioning the goals in diagonal configurations on the pitch modifies the external training load and the tactical behaviour of young football players during small-sided games. Four teams of five outfield players and a goalkeeper played six small-sided games of five minutes' duration in three different scenarios: 1) Control: goals placed one in front of the other; 2) Right diagonal goals: goals placed in the right-hand corner of the offensive half-pitch; and 3) Left diagonal goals: goals placed in the left-hand corner of the offensive half-pitch. The positioning-derived data from each player were collected with 10-Hz GPS units and were used to compute external load and tactical variables. Regarding the external load variables, differences were mainly focused on distance covered while walking in defence and game pace (variability), with higher values for the diagonal scenarios. Also, the length/width ratios in offence and defence were most likely lower in diagonal scenarios. In conclusion, the results showed that players' adaptations to the environmental constraints of positioning the goals diagonally were the enhancement of the width team variable and the variability of the length.
本研究的目的是确定在小场比赛期间，将球门设置在球场对角配置中如何改变年轻足球运动员的外部训练负荷和战术行为。四支由五名外场球员和一名守门员组成的球队在三种不同场景下进行了六场时长为五分钟的小场比赛：1）对照组：球门一个在另一个前面；2）右对角球门：球门设置在进攻半场的右上角；3）左对角球门：球门设置在进攻半场的左上角。使用10赫兹的GPS设备收集每个球员的位置衍生数据，并用于计算外部负荷和战术变量。关于外部负荷变量，差异主要集中在防守时行走的距离和比赛节奏（变异性）上，对角场景下的值更高。此外，对角场景下进攻和防守中的长宽比最有可能更低。总之，结果表明，球员对对角设置球门的环境限制的适应是宽度团队变量的增强和长度的变异性。
