This study aimed to compare the physiological demand between three vs. three small-sided games (SSGs) with (3vs.3) and without (3vs.3) the offside rule, as well as the within- and between-session reliability of this demand. Twenty-four U-17 soccer athletes performed various three vs. three (plus goalkeepers) SSGs with and without the offside rule. The data collection was performed within an eight-week period. Athletes' heart rate was monitored during the SSG. The variables analyzed were the percentage mean heart rate (HR) and the percentage peak heart rate (HR). For the analysis of within-session reliability, the mean value of the first two and last two SSG bouts performed within one day were used. The between-session reliability was calculated using the mean value of the four SSG bouts of each SSG type performed on two different days. In both SSGs, the values for reliability were significant and were classified as moderate to excellent. There were no significant differences in the physiological demand among SSG types. We concluded that the offside rule does not influence the physiological demand in a three vs. three SSG and the HR and HR present moderate to excellent reliability in a three vs. three SSG with and without the offside rule.
本研究旨在比较有（3vs.3）和无（3vs.3）越位规则的三种与三种小场比赛（SSG）之间的生理需求，以及这种需求的组内和组间可靠性。24 名 U-17 足球运动员进行了各种有（3vs.3）和无（3vs.3）越位规则的三人对三人（含守门员）SSG。数据采集在八周内进行。运动员的心率在 SSG 期间进行监测。分析的变量是平均心率（HR）的百分比和峰值心率（HR）的百分比。对于组内可靠性分析，使用同一天内前两个和最后两个 SSG 回合的平均值。使用两天内每个 SSG 类型的四个 SSG 回合的平均值计算组间可靠性。在两种 SSG 中，可靠性值均显著，分类为中等到优秀。SSG 类型之间的生理需求没有差异。我们得出结论，越位规则不会影响三人对三人 SSG 的生理需求，并且在有和无越位规则的三人对三人 SSG 中，心率和心率均具有中等到优秀的可靠性。
