短跑运动员的准确信息，如步幅、站立时间、步长、连续质心位移和分裂时间，对短跑教练员和生物力学研究人员都很重要。这些信息传统上是使用基于摄像头的系统捕获的，这是非常昂贵和耗时的设置。本文调查-通过一系列的实验-是否集成的传感系统将提供一个实用的，成本效益的替代测量短跑运动员的步幅相关信息。结果表明，该系统实现了5毫秒内的站立时间和步幅时间的测量精度，和定位相关的信息，如CoM向前位移和CoM步幅位移（即步幅）的~ 10厘米。
Accurate sprint-related information, such as stride times, stance times, stride lengths, continuous Centre-of-Mass (CoM) displacements and split times of sprinters are important to both sprint coaches and biomechanics researchers. These information are traditionally captured using camera-based systems which are very expensive and time-consuming to setup. This paper investigates - through a series of experiments - whether an integrated sensing system would provide a practical, cost-effective alternative to measuring stride-related information of sprinters. The results show that the system achieves an accuracy within 5ms for stance time and stride time measurements, and ~10cm for localisation-related information such as CoM forward displacement and CoM stride displacement (i.e. stride length).
