The aim of this study was to analyse variations of internal load across small-sided games (SSG) in professional soccer. Twenty players (mean ± SD; age 28.1 ± 4.6 yo, height 176.7 ± 4.9 cm, weight 72.0 ± 7.8 kg) performed 3v3, 4v4, and 6v6 formats with/without goalkeeper and touch limitations. Each condition was repeated over three sessions and heart rate (HR) measures including average HR (HR), Edwards' training impulse (Edwards' TRIMP) and time in red zone (>80% of maximal HR) were recorded. All measures had to- typical error (TE) and differences were observed within intervals. The HR showed less coefficient of variations (0.9% to 1.7%) compared to Edwards'TRIMPmin and red zonemin (2% to 9.7%). A reduction trend in TE was observed when touching limitations or using goalkeepers. Practitioners can use different SSG formats but if the aim is to have less noise at higher intensities, more controlled drills are recommended.
本研究旨在分析职业足球小场比赛（SSG）中内部负荷的变化。20 名球员（平均 ± 标准差；年龄 28.1 ± 4.6 岁，身高 176.7 ± 4.9 厘米，体重 72.0 ± 7.8 公斤）进行了 3v3、4v4 和 6v6 的有/无守门员和触球限制的比赛。每种条件重复进行 3 次，记录心率（HR）指标，包括平均 HR（HR）、爱德华兹训练冲动（Edwards' TRIMP）和红色区域时间（>80%最大 HR）。所有指标都有典型误差（TE），并且在间隔内观察到差异。与 Edwards'TRIMPmin 和 red zonemin（2% 到 9.7%）相比，HR 的变异系数较小（0.9% 到 1.7%）。当触球受限或使用守门员时，TE 呈下降趋势。教练可以使用不同的 SSG 格式，但如果目的是在更高强度下减少噪音，建议使用更受控的训练。
