The ability to accelerate and attain high velocities is essential for both individual and team sport athletes. The purpose of this explorative study was to retrospectively analyze the ground reaction force using Statistical Parametric Mapping (SPM) vector field analysis, as traditional scalar analyses often fail to acknowledge the interdependence of force vector components. The ground reaction force vector and the scalar components (i.e., vertical and horizontal force) were analyzed for 28 male sprinters and 24 male soccer players at 8.0 and 8.5 m·s−1, and between 85%, 90%, 95%, and 100% of their maximum velocity. The ground reaction force vector differed predominately during mid‐stance and late stance between both groups at 8.0 and 8.5 m·s−1. Within‐group analysis also revealed that in both groups, the first ~60% of stance tended to increase in relevance when transitioning to higher sprinting velocities as evident by the increasing {T2} test statistic between adjacent velocity comparisons. Sprinters and soccer player reached their respective maximal sprinting velocity at ~40 m. This exploratory study discusses the potential limitations of scalar analysis and highlights the benefits of incorporating vector field analysis. Although both analysis methods resulted in similar conclusions in our re‐analysis, vector field analysis may still enhance the understanding of force application in sprint performance by considering the interdependence of force components. We recommend utilizing vector field analyses alongside traditional methods in sports biomechanics research to ultimately enhance the accuracy of interpretations related to vector data.

男子足球运动员和短跑运动员最大冲刺努力过程中地面反作用力的探索性矢量场分析


加速和达到高速的能力对于个人和团队运动运动员都是必不可少的。这项探索性研究的目的是使用统计参数映射 （SPM） 矢量场分析回顾性分析地面反作用力，因为传统的标量分析通常无法承认力矢量分量的相互依赖性。分析了 28 名男子短跑运动员和 24 名男子足球运动员在 8.0 和 8.5 m·s−1 以及最大速度的 85%、90%、95% 和 100% 之间的地面反作用力矢量和标量分量（即垂直和水平力）。两组之间的地面反作用力矢量在 8.0 和 8.5 m·s−1 的中站姿和晚姿态中主要存在差异。组内分析还显示，在两组中，当过渡到更高的冲刺速度时，前 ~60% 的站姿往往相关性增加，相邻速度比较之间增加的 {T2} 检验统计量就证明了这一点。短跑运动员和足球运动员在 ~40 m 处达到各自的最大冲刺速度。这项探索性研究讨论了标量分析的潜在局限性，并强调了结合矢量场分析的好处。尽管两种分析方法在我们的重新分析中得出了相似的结论，但矢量场分析仍然可以通过考虑力分量的相互依赖性来增强对冲刺性能中力应用的理解。我们建议在运动生物力学研究中将矢量场分析与传统方法结合使用，以最终提高与矢量数据相关的解释的准确性。
