The aim of this study was to compare external training loads between small-sided games (SSGs) and largesided games (LSGs) in soccer players. Twenty outfield soccer players (14.8 ± 0.6 years old) who competed in the Spanish U16 Provincial Division and belonged to the same team participated in the study. The soccer sided games were played at different individual interaction space (IIS) per player (i.e., SSG = 100 m and LSG = 200 m) and were disputed in the same format (five-a-side plus goalkeepers) on two different pitch sizes (i.e., 38 x 26 vs. 53 x 37 m) defending an official soccer-goal. The sided games' duration was 4 bouts of 6 min with 2 min rest intervals between bouts. The results of this study showed no meaningful differences in the total distance and intensity of accelerations and decelerations between SSGs and LSGs except for the lower distance covered at medium intensity (2.5 - 4 m·s) observed during LSGs (-10.2%; ES (effect size): -0.51). Players registered greater sprints, maximum velocity (Vel) and body impacts at different intensities (i.e., I5-6g, I6-6.5g, I6.5-7g, I7-8g, I8-10g,) in LSGs in comparison to SSGs. These findings suggest that an increase in the pitch size (i.e., IIS per player) can induce higher external loads for soccer players.
本研究的目的是比较足球运动员在小型比赛（SSG）和大型比赛（LSG）中的外部训练负荷。20名参加西班牙U16省级联赛且来自同一球队的外场足球运动员（14.8±0.6岁）参与了该研究。足球比赛在不同的每位球员个人交互空间（IIS）下进行（即，SSG = 100米，LSG = 200米），并在两种不同的场地尺寸（即38×26米与53×37米）上以相同的形式（五人制加守门员）进行，防守正规足球门。比赛持续时间为4轮，每轮6分钟，轮间休息2分钟。本研究结果表明，除了在LSG中观察到的中等强度（2.5 - 4米·秒）下覆盖的距离较低（-10.2%；效应量（ES）：-0.51）外，SSG和LSG之间在总距离以及加速和减速强度方面没有显著差异。与SSG相比，球员在LSG中记录到更高的冲刺次数、最大速度（Vel）以及不同强度（即I5 - 6g、I6 - 6.5g、I6.5 - 7g、I7 - 8g、I8 - 10g）下的身体碰撞次数。这些发现表明，场地尺寸的增加（即每位球员的IIS）会给足球运动员带来更高的外部负荷。
