The objectives of this study were twofold: (a) to analyze the variability of 3v3 and 5v5 small-sided games (SSG) formats in sedentary young adults, and (b) to compare the physiological and locomotor demands of 3v3 and 5v5 SSG formats while considering variations based on sex. The study followed a longitudinal design over 4 months. Thirty sedentary young adults with a mean age of 20.2 ± 1.0 years, height of 1.67 ± 0.06 m, and body mass of 86.3 ± 11.8 kg were included in the study. The participants engaged in 3v3 and 5v5 SSG formats, with each format being played 10 times per month. During each session, heart rate (HR), rate of perceived exertion (RPE), and total distance were measured and analyzed. The within-player variability for HR ranged from a minimum of 1.6% to a maximum of 2.8% (considering the levels at each month), while the between-players variability for HR ranged from a minimum of 1.4% to a maximum of 2.6% (considering the levels at each month). Similar variability patterns were observed for the other outcomes. In terms of comparisons between the formats, the 3v3 format resulted in higher RPE than the 5v5 format for both male ( p = 0.006) and female ( p = 0.628) participants, as well as for the other outcome measures. In summary, these findings highlight the reproducibility of physiological responses in 3v3 and 5v5 SSG among sedentary individuals. Notably, the 3v3 format consistently induced higher RPE levels. These findings underscore the importance of programming SSG based on sex and format preferences for optimizing exercise outcomes in sedentary.

3v3 和 5v5 小场足球赛制的生理和运动变化：一项针对久坐年轻人的为期 4 个月的研究

本研究的目的有两个：(a) 分析久坐的年轻人中 3v3 和 5v5 小场比赛 (SSG) 形式的变异性；(b) 比较 3v3 和 5v5 SSG 形式的生理和运动需求，同时考虑基于性别的差异。该研究采用了为期 4 个月的纵向设计。该研究包括 30 名久坐的年轻人，平均年龄为 20.2 ± 1.0 岁，身高为 1.67 ± 0.06 m，体重为 86.3 ± 11.8 kg。参赛者采用3v3和5v5 SSG赛制，每种赛制每月进行10次。在每次训练期间，测量并分析心率 (HR)、感知用力率 (RPE) 和总距离。玩家内部的 HR 变异性范围从最小 1.6% 到最大 2.8%（考虑每个月的水平），而玩家之间的 HR 变异性范围从最小 1.4% 到最大 2.6% （考虑每个月的水平）。其他结果也观察到类似的变异模式。就两种形式之间的比较而言，对于男性（p = 0.006）和女性（p = 0.628）参与者以及其他结果指标而言，3v3 形式的 RPE 高于 5v5 形式。总之，这些发现强调了久坐个体中 3v3 和 5v5 SSG 生理反应的可重复性。值得注意的是，3v3 模式始终会诱导更高的 RPE 水平。这些发现强调了根据性别和形式偏好对 SSG 进行编程对于优化久坐运动结果的重要性。
