Soccer is a popular team sport and highly demanding activity that requires high effort and long-term training plans. The goals of this study were to compare the accelerations, decelerations and metabolic power between official and friendly full matches, between the first and second halves of the matches, and between both halves of official and friendly matches. Twelve professional soccer players (age, 28.6 ± 2.7 years; height, 182.1 ± 8.6 cm; body mass, 75.3 ± 8.2 kg; BMI, 22.6 ± 0.7 kg/m) participated in this study. A total of 33 official and 10 friendly matches were analyzed from the Iranian Premier League. All matches were monitored using GPSPORTS systems Pty Ltd. The following variables were selected: total duration of the matches, metabolic power, accelerations Zone1 (<2 m·s) (AccZ1), accelerations Zone2 (2 to 4 m·s) (AccZ2), accelerations Zone3 (>4 m·s) (AccZ3), decelerations Zone1 (<-2 m·s) (DecZ1), decelerations Zone2 (-2 to -4 m·s) (DecZ2) and decelerations Zone3 (>-4 m·s) (DecZ3). The major finding was shown in metabolic power, where higher values occurred in friendly matches ( < 0.05 with small effect size). Furthermore, total duration, AccZ3, DecZ1, DecZ2, and DecZ3 were revealed to be higher in official matches, while AccZ1 and AccZ2 were higher in friendly matches. The second half of the official matches revealed higher values for total duration compared to friendly matches ( < 0.05, moderate effect size). In conclusion, this study observed higher values of metabolic power in friendly matches compared to official matches. AccZ3, DecZ1, DecZ2, and DecZ3 were higher in official matches, while AccZ1 and AccZ2 were higher in friendly matches.
足球是一项流行的团队运动，需要高强度的努力和长期的训练计划。本研究的目的是比较正式比赛和友谊赛的全速冲刺、减速和代谢功率，以及比赛上下半场和正式比赛与友谊赛之间的差异。12 名职业足球运动员（年龄 28.6±2.7 岁；身高 182.1±8.6cm；体重 75.3±8.2kg；BMI 22.6±0.7kg/m）参与了这项研究。从伊朗超级联赛中分析了 33 场正式比赛和 10 场友谊赛。所有比赛都使用 GPSPORTS 系统 Pty Ltd 进行监测。选择了以下变量：比赛总时长、代谢功率、Zone1 加速（<2m·s）（AccZ1）、Zone2 加速（2 到 4m·s）（AccZ2）、Zone3 加速（>4m·s）（AccZ3）、Zone1 减速（<-2m·s）（DecZ1）、Zone2 减速（-2 到-4m·s）（DecZ2）和 Zone3 减速（>-4m·s）（DecZ3）。主要发现是在代谢功率方面，友谊赛中呈现出更高的值（<0.05，小效应量）。此外，正式比赛的总时长、AccZ3、DecZ1、DecZ2 和 DecZ3 更高，而友谊赛中 AccZ1 和 AccZ2 更高。与友谊赛相比，正式比赛的下半场总时长更高（<0.05，中等效应量）。总之，本研究观察到友谊赛中的代谢功率值高于正式比赛。正式比赛中 AccZ3、DecZ1、DecZ2 和 DecZ3 更高，而友谊赛中 AccZ1 和 AccZ2 更高。
