The aim of the present study was to analyze motor activities of soccer players in seven consecutive rounds of matches of the 2014 World Cup in Brazil and to compare the performance of the world champions, the German national team with other participating teams. The study sample comprised 905 observations of 340 soccer players, who played full-time matches in all seven rounds of the tournament. The study was conducted using data collected from the Castrol Performance Index, a kinematic game analysis system that records movements of players with semi-automatic cameras. The following variables were analyzed: total distance covered, the percentage of total distance covered at high intensity, the number of sprints, frequency of sprints and peak running speed. A statistically significant increase (p ≤ 0.01) was noted in total distance covered, the percentage of distance covered at high intensity and total number of sprints, between the quarter-finals and semi-finals of the World Cup tournament in Brazil. The German national team covered a significantly longer total distance (p ≤ 0.05) and had a greater percentage of distance covered at high intensity (p ≤ 0.001) than players from other teams. The obtained results point to the necessity of development of players' aerobic endurance and speed-endurance abilities while preparing for top-level soccer tournaments. Winning a soccer championship requires players to run longer mean total distances and longer distances at high intensity during a single match.
本研究的目的是分析参加2014年巴西世界杯七轮连续比赛的足球运动员的运动活动，并将世界冠军德国国家队与其他参赛队伍的表现进行比较。研究样本包括对340名足球运动员的905次观察，这些运动员参加了比赛全部七轮的全场比赛。该研究使用从嘉实多性能指数收集的数据进行，嘉实多性能指数是一个运动学比赛分析系统，它通过半自动摄像机记录球员的动作。分析了以下变量：总跑动距离、高强度跑动距离占总距离的百分比、冲刺次数、冲刺频率和最高奔跑速度。在巴西世界杯四分之一决赛和半决赛之间，总跑动距离、高强度跑动距离占比和冲刺总次数有统计学显著增加（p≤0.01）。德国国家队的总跑动距离显著更长（p≤0.05），且高强度跑动距离占比更高（p≤0.001）。研究结果表明，在为顶级足球赛事做准备时，培养球员的有氧耐力和速度耐力能力很有必要。赢得足球冠军要求球员在单场比赛中跑动更长的平均总距离和更长的高强度距离。
