To perform an exploratory characterization of repeated sprint sequences (RSS) and repeated acceleration sequences (RAS) in top level soccer referees.
7 field and 7 assistant referees were monitored during 2007 America's Soccer Cup with GPS technology. Sprints of >18 km·h(-1) and accelerations of >1.5 m·s(-2) were considered as high intensity activities. RSS and RAS were defined as a minimum of 3 consecutive bouts interspersed with a maximum of 45 s.
Field and assistant referees performed substantially more accelerations than sprints. Neither field nor assistant referees recorded any RSS. In contrast, total distance performing RAS amounted to ∼37% and ∼20% of the total distance covered by accelerations during the entire match for field and assistant referees, respectively. Only field referees exhibited fatigue-related reductions in RAS characteristics between halves.
The results of the present study would appear to support the appropriateness of a repeated acceleration ability (RAA) concept, instead of the repeated sprint ability (RSA) concept, in soccer referees. Further studies should assess RAS in referees and athletes of different team sports for designing better training exercises and physiological testing.
对顶级足球裁判的重复冲刺序列(RSS)和重复加速序列(RAS)进行探索性特征分析。
在2007年美洲足球杯期间,使用GPS技术对7名场上裁判和7名助理裁判进行监测。速度大于18 km·h⁻¹的冲刺和加速度大于1.5 m·s⁻²的加速被视为高强度活动。RSS和RAS被定义为至少3次连续的活动回合,中间间隔最长为45秒。
场上裁判和助理裁判的加速次数明显多于冲刺次数。场上裁判和助理裁判均未记录到任何RSS。相比之下,对于场上裁判和助理裁判,执行RAS的总距离分别占整场比赛加速总距离的约37%和约20%。只有场上裁判在下半场表现出与疲劳相关的RAS特征下降。
本研究结果似乎支持在足球裁判中采用重复加速能力(RAA)概念而非重复冲刺能力(RSA)概念的合理性。进一步的研究应评估不同团队运动的裁判和运动员的RAS,以设计更好的训练练习和生理测试。
