Abstract

The objective of the present study was to describe the total and fragmented external loads, at different intensities, of soccer referees in European and South American competitions during official matches through a systematic review and meta-analysis of cross-sectional studies. A systematic review was conducted in April, 2020. In all, 32 studies were included, incorporating 578 referees evaluated in 3170 games through video analysis or a global positioning system. Regarding external loads, it was observed that the total average distance covered by the referees was 10,461.74 m, with running speeds predominantly below 13 km.h^-1. The total distance covered by the referees in the European competitions was higher and more intense than that of the referees in the South American tournaments, being 11,187.02 m and 9319.61 m, respectively. We suggest that referees' training can be organized according to the distances found at different intensities, in which low-intensity races can be performed below 13 km.h-¹ with distances of approximately 4500 m, while high-intensity training can be developed with speeds from 18 to 24 km.h-¹ for approximately 800 m. In addition, planning must consider the competition characteristics.

优秀足球裁判的外部负荷:系统回顾与荟萃分析。

本研究的目的是通过横断面研究的系统回顾和荟萃分析，描述欧洲和南美足球比赛中裁判在不同强度下的总外负荷和碎片外负荷。2020年4月进行了系统评价。总共包括32项研究，通过视频分析或全球定位系统对3170场比赛中的578名裁判进行了评估。关于外部负载，据观察，裁判员的总平均距离为10 461.74米，奔跑速度主要低于13公里每小时。欧洲裁判员的总跑动距离比南美裁判员的跑动距离更高，跑动距离也更密集，分别为11187.02米和9319.61米。我们建议可以根据裁判在不同强度下的距离进行训练，其中低强度比赛可以在13 km.h-1以下进行，距离约为4500 m，高强度训练可以在18 - 24 km.h-1之间进行，距离约为800 m。此外，规划必须考虑竞争特点。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
