Abstract

The purpose of this study was to compare the center of mass and pelvis movement measured by the inertia sensor, motion capture, and ground reaction force during running. Linear movements of the center of mass and pelvis rotation were measured by motion capture system and the inertia sensor mounted on sacrum for thirteen distance runners. Vertical movement of the sensor was well coincident with the center of mass but lateral and forward/backward movements were overestimated by the sensor. The forward tilt, tangular displacement and velocity of pelvis in a running cycle were almost same in the values by motion capture and sensor with some variances by the mounted position. It would be suggested that the inertia sensor is useful to evaluate the distance running motion with filtering and modification of offset and parameter relationship for individual.
