Limited evidence exists on how segmental external load is distributed during linear running and how it varies with speed, training intensity, and individual differences. This study examines the external load profile across six body segments in elite female futsal players during linear treadmill running, focusing on the effects of speed and training zone, as well as individual variability. Eight elite players, including six outfield players and two goalkeepers (mean age 23.9 ± 3.4 years, height 164.96 ± 4.22 cm, body mass 60.31 ± 4.56 kg), performed an incremental test and were measured using six WIMU PRO™ inertial sensors. The sensors recorded segmental PlayerLoad, speed, and training zones. Data were analyzed using Linear Mixed Models. The most important results show significant interactions between body location and speed and between body location and training zone ( < 0.001), with intraclass correlation coefficients (ICC) ranging from 0.437 to 0.515. These results indicate variability among players and specific and asymmetrical segmental load patterns. These findings offer practical insights for tailoring individualized training strategies that optimize performance and reduce segment specific overuse injuries.
关于直线跑步过程中节段性外部负荷如何分布以及它如何随速度、训练强度和个体差异而变化的证据有限。本研究考察了精英女子五人制足球运动员在直线跑步机跑步过程中六个身体节段的外部负荷情况，重点关注速度和训练区域的影响以及个体差异。八名精英球员，包括六名外场球员和两名守门员（平均年龄23.9±3.4岁，身高164.96±4.22厘米，体重60.31±4.56千克），进行了递增测试，并使用六个WIMU PRO™惯性传感器进行测量。传感器记录了节段性球员负荷、速度和训练区域。数据采用线性混合模型进行分析。最重要的结果显示身体部位与速度之间以及身体部位与训练区域之间存在显著交互作用（<0.001），组内相关系数（ICC）范围为0.437至0.515。这些结果表明球员之间存在差异以及存在特定的和不对称的节段负荷模式。这些发现为制定个性化训练策略提供了实用见解，以优化表现并减少特定节段的过度使用损伤。
