Abstract
Inertial sensors have the potential to measure and monitor loads during running in ecologically valid settings. The aim of this study was to investigate the suitability of an inertial sensor to estimate ground reaction force from resultant acceleration in comparison to a force plate (FP). An inertial sensor was placed on the sacrum of three participants who undertook six runs at 3, 4 and 5 m/s over a FP. A strong correlation (r = 0.94) was observed for resultant step average force; with moderate CV % (9.20 %) and root mean square error (RMSE) (10.31 %) between the FP and force estimate derived from acceleration (FAcc). Moderate correlation (r = 0.52), large CV % (25.55 %) and RMSE (36.22 %) were observed for peak resultant ground reaction force. Inertial sensors have potential to estimate average force, but should be used with caution due to the error compared with FP data (> 10 %).
