The study aim was to analyse the effects of manipulating the space and number of players in small-sided games on the external load demands of futsal athletes of different age categories. Fifty-six male futsal players from U15, U17, U19, and adult age categories participated. The study lasted 7 weeks. The first week was for familiarization and evaluations to characterize the sample. In the six subsequent weeks there were six futsal tasks T1 (GK + 2 × 2 + GK, 20 × 20 m), T2 (GK + 2 × 2 + GK, 40 × 20 m), T3 (GK + 3 × 3 + GK, 20 × 20 m), T4 (GK + 3 × 3 + GK, 40 × 20 m), T5 (GK + 4 × 4 + GK, 20 × 20 m), and T6 (GK + 4 × 4 + GK, 40 × 20 m). The external load variables were measured with an inertial measurement unit (IMU), and kinematic (total and relative distance) and mechanical (total distance at high intensity accelerations and decelerations) data were extracted. T2 (133 m) showed higher values for total distance covered (1248.0 ± 97.6 m) and distances covered at speeds between 12.1 and 18 km/h (407.8 ± 44.7 m) and greater than 18.1 km/h (115.2 ± 28.9 m) compared to T5 (40 m) and T6 (80 m). In addition, we observed greater variability in high-intensity accelerations and high-intensity decelerations, suggesting that regardless of field size and number of players, relative area might not play as crucial a role in this dimension.
本研究旨在分析在小型比赛中改变场地空间和球员数量对不同年龄组室内五人制足球运动员外部负荷需求的影响。来自U15、U17、U19和成人年龄组的56名男性室内五人制足球运动员参与了研究。该研究持续了7周。第一周用于熟悉环境和进行评估以描述样本特征。在随后的六周里，有六项室内五人制足球任务：T1（守门员 + 2×2 + 守门员，20×20米）、T2（守门员 + 2×2 + 守门员，40×20米）、T3（守门员 + 3×3 + 守门员，20×20米）、T4（守门员 + 3×3 + 守门员，40×20米）、T5（守门员 + 4×4 + 守门员，20×20米）和T6（守门员 + 4×4 + 守门员，40×20米）。使用惯性测量单元（IMU）测量外部负荷变量，并提取运动学数据（总距离和相对距离）和力学数据（高强度加速和减速时的总距离）。与T5（40米）和T6（80米）相比，T2（133米）在总跑动距离（1248.0±97.6米）以及速度在12.1至18公里/小时之间的跑动距离（407.8±44.7米）和大于18.1公里/小时的跑动距离（115.2±28.9米）方面显示出更高的值。此外，我们观察到高强度加速和高强度减速的变异性更大，这表明无论场地大小和球员数量如何，相对面积在这方面可能并非起着至关重要的作用。
