Background: The purpose of this study is to compare training load (TL) preceding a home versus away match in a top-class elite European team during the 2015–2016 season. Methods: Twenty elite outfield soccer players with a mean ± SD age, height and body mass of 25.9 ± 4.6 years, 183.1 ± 6.6 cm and 78.6 ± 6.6 kg, respectively, participated in this study. Total distance covered, high-speed running distance (HSRD), average speed (AvS), rating of perceived exertion (RPE) multiplied by training duration (s-RPE) and Hooper index (HI) were collected. Data from 24 weeks were analyzed through match-day minus/plus approach (MD-5, -4, -3, -2, -1, MD + 1). Results: All external TL variables indicated a decrease from MD-5 until MD-1 and then an increase to MD + 1 (p < 0.01). HI decreased from MD-5 to MD-1, but s-RPE increased until MD-3 and then decreased until MD + 1. When comparing TL data that preceded home matches versus away matches, for MD-5, HSRD and muscle soreness exhibited higher values when away match neared (p < 0.05). For MD-4 and MD-3, total distance, HSRD and AvS exhibited higher values closer to an away match than a home match (p < 0.05). For MD-1, total distances covered were higher closer to a home match than an away match (p < 0.01). For MD + 1, all HI items and AvS were higher when an away match was played (p < 0.05). Conclusions: This study confirms and provides evidence regarding the influence on internal and external TL data preceding home and away matches from a team that played in European competitions.

下一场比赛的位置会影响一支顶级欧洲职业足球精英队的内部和外部训练负荷吗？

背景：本研究的目的是比较2015-2016赛季欧洲顶级精英队在主场与客场比赛前的训练负荷（TL）。方法：20名平均年龄±SD，身高和体重分别为25.9±4.6岁，183.1±6.6 cm和78.6±6.6 kg的精英外场足球运动员参加了这项研究。收集总覆盖距离，高速跑步距离（HSRD），平均速度（AvS），感知劳累等级（RPE）乘以训练持续时间（s-RPE）和胡珀指数（HI）。通过比赛日的减号/加号方法（MD-5，-4，-3，-2，-1，MD +1）分析了24周的数据。结果：所有外部TL变量均指示从MD-5降低到MD-1，然后增加到MD + 1（p<0.01）。HI从MD-5下降到MD-1，但s-RPE一直上升到MD-3，然后下降直到MD + 1。当比较主场比赛与客场比赛之前的TL数据时，对于MD-5表现出HSRD和肌肉酸痛距离相近时较高的值（p <0.05）。对于MD-4和MD-3，总距离，HSRD和AvS在离客队比赛中比在主场比赛中表现出更高的值（p <0.05）。对于MD-1，与主场比赛相比，主场比赛的总距离更高（p <0.01）。对于MD + 1，在进行客场比赛时，所有HI项目和AvS均较高（p<0.05）。结论：这项研究证实并提供了证据，说明在参加欧洲比赛的球队进行主场和客场比赛之前，这些数据对内部和外部TL数据的影响。
