The aim was to analyse the influence of the offside rule and pitch sizes on the external loads encountered by young soccer players during small-sided games (SSGs). Twenty-four U12 soccer players belonged to the same Spanish Performance Soccer Academy participated in the study. Each player participated in six different SSGs attending to the offside rule (i.e., offside not applicable [NOS] and with offside [WOS]) and the pitch sizes (i.e., individual interaction space [IIS] of 25, 50 and 75 m per player). The obtained data included measures of external loads by global positioning systems. Players covered higher total distance and greater distances at jogging (8-12.9 km·h), cruising (13.0-16.0 km·h) and sprinting (>16.0 km·h) in NOS and WOS SSGs ( < 0.01; d = 0.65-6.60). Besides, in the NOS SSG, the total distance and the distance at cruising were higher in respect to WOS ( < 0.01; d = 0.63-0.82). In addition, players performed lower sprints ( < 0.01; d = 1.17-1.71) and achieved lower V ( > 0.05; d = 1.10-1.88) during NOS and WOS SSGs. These findings could provide relevant information for coaches in order to apply different pitch sizes and the inclusion/absence of the offside rule throughout the microcycle.
本研究旨在分析越位规则和场地大小对青少年足球运动员小场地比赛（SSG）中遭遇的外部负荷的影响。24 名来自同一西班牙表现足球学院的 U12 足球运动员参与了本研究。每位运动员参加了六种不同的 SSG，包括越位规则（即不适用越位 [NOS] 和适用越位 [WOS]）和场地大小（即每个球员的个人互动空间 [IIS] 为 25、50 和 75 米）。获得的数据包括全球定位系统测量的外部负荷。在 NOS 和 WOS SSG 中，运动员在 NOS 和 WOS SSG 中，总距离和慢跑（8-12.9km·h）、巡航（13.0-16.0km·h）和冲刺（>16.0km·h）的距离更大（<0.01；d=0.65-6.60）。此外，在 NOS SSG 中，总距离和巡航距离大于 WOS（<0.01；d=0.63-0.82）。此外，运动员在 NOS 和 WOS SSG 中冲刺次数较少（<0.01；d=1.17-1.71），V 也较低（>0.05；d=1.10-1.88）。这些发现可以为教练提供相关信息，以便在微周期中应用不同的场地大小和包括/不包括越位规则。
