Time-motion analysis is a valuable data-collection technique used to quantify the physical match performance of elite soccer players. For over 40 years, researchers have adopted a "traditional" approach when evaluating match demands by simply reporting the distance covered or time spent along a motion continuum of walking through to sprinting. This methodology quantifies physical metrics in isolation without integrating other factors, and this ultimately leads to a 1-dimensional insight into match performance. Thus, this commentary proposes a novel "integrated" approach that focuses on a sensitive physical metric such as high-intensity running but contextualizes this in relation to key tactical activities for each position and collectively for the team. In the example presented, the integrated model clearly unveils the unique high-intensity profile that exists due to distinct tactical roles, rather than 1-dimensional "blind" distances produced by traditional models. Intuitively, this innovative concept may aid coaches' understanding of the physical performance in relation to the tactical roles and instructions given to the players. In addition, it will enable practitioners to effectively translate match metrics into training and testing protocols. This innovative model may well aid advances in other team sports that incorporate similar intermittent movements with tactical purpose. Evidence of the merits and application of this new concept is needed before the scientific community accepts this model as it may well add complexity to an area that conceivably needs simplicity.
时间-动作分析是一种有价值的数据收集技术,用于量化精英足球运动员的身体比赛表现。40 多年来,研究人员通过简单地报告沿着从步行到冲刺的运动连续体覆盖的距离或花费的时间,采用“传统”方法来评估比赛需求。这种方法将物理指标孤立地量化,而不整合其他因素,这最终导致对比赛表现的一维洞察。因此,本评论提出了一种新颖的“综合”方法,该方法侧重于高强度跑动等敏感的物理指标,但将其与每个位置和整个团队的关键战术活动联系起来。在提出的示例中,综合模型清楚地揭示了由于独特的战术角色而存在的独特高强度剖面,而不是传统模型产生的一维“盲目”距离。直观地说,这个创新的概念可以帮助教练理解与战术角色和给球员的指令相关的身体表现。此外,它将使从业者能够有效地将比赛指标转化为训练和测试方案。这个创新的模型可能有助于包含类似间歇性运动和战术目的的其他团队运动的进步。在科学界接受这个模型之前,需要证明这个新概念的优点和应用,因为它可能会给本应简单的领域增加复杂性。
