Is technical performance related to the distance covered during U-19 futsal matches?

Abstract The aim of the present study was to quantify the physical demand in terms ofdistance covered and to verify the relation with technical performance during simulated futsal matches of U-19 category. Sixteen players participated in the study. Two simulated matches were performed, and the physical demand was quantified by the total distance covered, distance covered per minute and distance at different intensities. In addition, technical performance variables were analyzed during matches. The total distance covered was, on average, 3259.97 ± 180.27 m, with 113.26 ± 6.11 m / min. Approximately 26% of the total distance was covered at high intensity (i.e.,> 15 km.h-1), with significant decrease of these actions in the second half of matches (p

摘要
本研究旨在以跑动距离为量化指标，对U19（U-19）组别五人制足球（futsal）模拟比赛中的体能负荷进行评估，并验证体能负荷与赛事技术表现之间的关联。本研究共招募16名运动员，受试者完成两场模拟比赛，通过总跑动距离、每分钟跑动距离及不同强度下的跑动距离对体能负荷进行量化。此外，本研究还对比赛中的技术表现变量进行了分析。受试者的平均总跑动距离为3259.97±180.27米，平均每分钟跑动距离为113.26±6.11米。约26%的总跑动距离为高强度跑动（即速度＞15km·h⁻¹），且比赛下半场的此类高强度跑动动作显著减少（p
