The aim of this study was twofold: (i) to examine the variations of estimated maximal aerobic speed between non, low and high responders and (ii) to analyze the relationships between accumulated training load parameters and variations of maximal aerobic speed in children soccer players. Forty-four male soccer players were assessed three times during the early and mid-season (second to fifth month of the season) and were monitored daily over the period of analysis using the rating of perceived exertion (RPE), recording the training duration (in min) and calculating the session-RPE (sRPE). Pairwise comparisons revealed that maximal aerobic speed (MAS) was greater for the third assessment than the first (p-value [p] = 0.003; standardized effect of Cohen [d] = 0.355) and second (p = 0.013; d = 0.193) assessments. Large correlations were found between MAS and accumulated RPE, accumulated time, and accumulated sRPE. Moreover, non, low and high responders differed in ΔMAS (p<0.001) with the last group presenting the largest improvement in MAS. Results suggest that children with lower MAS baseline levels will improve more this capacity over the early and mid-season period compared to children with better baseline levels. Moreover, associations between accumulated training load and MAS were found, suggesting that the training effort can be related with aerobic capacity changes.
（i）检查无反应者、低反应者和高反应者之间估计的最大有氧速度的差异；（ii）分析儿童足球运动员累积训练负荷参数与最大有氧速度变化之间的关系。44名男性足球运动员在赛季早期和中期（赛季的第二个月至第五个月）接受了三次评估，并在分析期间每天使用主观用力感觉评分（RPE）进行监测，记录训练时长（分钟）并计算训练课RPE（sRPE）。两两比较显示，第三次评估的最大有氧速度（MAS）高于第一次（p值=0.003；科恩标准化效应d=0.355）和第二次评估（p=0.013；d=0.193）。MAS与累积RPE、累积时间和累积sRPE之间存在高度相关性。此外，无反应者、低反应者和高反应者在ΔMAS方面存在差异（p<0.001），最后一组的MAS改善最大。结果表明，与基线水平较好的儿童相比，基线水平较低的儿童在赛季早期和中期该能力的改善更大。此外，还发现了累积训练负荷与MAS之间的关联，表明训练强度可能与有氧能力变化有关。
