ABSTRACT

This study evaluated the estimated jump height (JH) differences between an inertial measurement unit (IMU), a linear position transducer (LPT), and two force plates (FPs). Thirty-eight student-athletes were recruited to perform vertical jumps that were simultaneously recorded using two dual-axis FPs (criterion measure), an LPT and an IMU. Very large and almost perfect linear relationships were observed between the IMU (r = 0.82) and LPT (r = 0.94) in relation to the FP. However, due to moderate significant JH differences observed for the LPT (+0.06 m; 20%) and IMU (+0.08 m, 28%) in comparison to the FPs, interchangeability is not recommended.

摘要

这项研究评估了惯性测量单元（IMU），线性位置传感器（LPT）和两个测力板（FP）之间的估计跳跃高度（JH）差异。招募了38名学生运动员进行垂直跳跃，同时使用两个双轴FP（标准量度），LPT和IMU记录了垂直跳跃。相对于FP，在IMU（r = 0.82）和LPT（r = 0.94）之间观察到非常大且几乎完美的线性关系。但是，由于与FP相比，在LPT（+0.06 m; 20％）和IMU（+0.08 m，28％）上观察到适度的显着JH差异，因此不建议互换性。
