: The aim of this study was to evaluate the reproducibility of internal and external load parameters during recreational small-sided football games. : Ten healthy untrained young adult males (age: 20.2 ± 1.9 yr, body mass: 69.2 ± 6.3 kg, height: 175.4 ± 5.9 cm, body fat: 19.7 ± 5.2%) performed two 2 × 20-min sessions of four versus four plus goalkeeper small-sided games (SSG) 1 week apart on a standard, outdoor, 40 × 20-m artificial grass pitch. Twelve external (total distance, peak speed, player load, work rate and distance covered at 0-2, 2-5, 5-7, 7-9, 9-13, 13-16, 16-20 and >20 km/h) and seven internal load parameters (heart rate and time spent in different heart rate zones [<70%, 71-80%, 81-90%, 91-95%, 96-100%, 91-100%]) were measured. Reproducibility was reported as intraclass coefficient correlation (ICC), the coefficient of variation (CV), and the typical error of measurements (TE). : No statistical differences (> .05) between sessions were found in any measures. Minimal test-retest variability was noted for mean and peak heart rate (HR) relative to HR with CV values of 3.4% and 2.6%, respectively. Acceptable variability (CV<10%) was demonstrated for total distance covered, distance covered at 2-5 km/h, and peak speed. Distance covered in different speed zones (CV = 15.7-47.6%) and percentage of time in each HR zone showed large-to-very large variability (CV = 36.2-128.4%). Mean heart rate (HR), HR, distance covered at 5-7, 13-16 and >20 km/h, and percentage of time above 95%HR were the most reliable variables (ICC = 0.74-0.79), followed by total distance covered, peak speed, and percentage of time at 80-90% HR (ICC = 0.39-0.67). The lowest reliability was observed for distance covered in the moderate speed zones 7-9 km/h (ICC = 0.12) and 9-13 km/h (ICC = -0.09), and percentage of time at 70-80% HR (ICC = -0.01). : Small-sided games can be used when planning training-induced exercise responses in relation to total distance covered, peak speed, and mean heart rate. This evidence further supports the use of SSG when organizing recreational football training, in young adult males, with the purpose of improving health profile due to the high reproducibility of HR and total distance covered.
本研究旨在评估休闲小场足球比赛中内部和外部负荷参数的可重复性。 10 名健康未训练的年轻成年男性（年龄：20.2 ± 1.9 岁，体重：69.2 ± 6.3 千克，身高：175.4 ± 5.9 厘米，体脂：19.7 ± 5.2%）在标准的户外 40×20 米人造草皮上，每周进行两次 2×20 分钟的 4 对 4 加守门员小场比赛（SSG），相隔一周。测量了 12 个外部（总距离、峰值速度、球员负荷、工作率和 0-2、2-5、5-7、7-9、9-13、13-16、16-20 和 >20 km/h 之间的距离）和 7 个内部负荷参数（心率和不同心率区的时间 [<70%、71-80%、81-90%、91-95%、96-100%、91-100%])。报告了组内系数相关性（ICC）、变异系数（CV）和测量的典型误差（TE）的再现性。在任何措施中，两次会议之间均未发现统计学差异（>.05）。平均和峰值心率的相对心率的测试-再测试变异性最小（CV 值分别为 3.4%和 2.6%）。总距离、2-5 km/h 之间的距离和峰值速度表现出可接受的变异性（CV<10%）。不同速度区的距离（CV=15.7-47.6%）和每个 HR 区的时间百分比显示出较大至非常大的变异性（CV=36.2-128.4%）。平均心率（HR）、峰值速度、5-7、13-16 和>20 km/h 之间的距离和超过 95%HR 的时间百分比是最可靠的变量（ICC=0.74-0.79），其次是总距离、峰值速度和 80-90%HR 的时间百分比（ICC=0.39-0.67）。在 7-9 km/h（ICC=0.12）和 9-13 km/h（ICC=-0.09）的中等速度区和 70-80%HR 的时间百分比（ICC=-0.01）的可重复性最低。小场比赛可用于规划与总距离、峰值速度和平均心率相关的训练诱导的运动反应。这一证据进一步支持在年轻男性中使用 SSG 组织休闲足球训练，以提高健康水平，因为 HR 和总距离的可重复性很高。
