Abstract
INTRODUCTION: The zero-velocity update (ZUPT) method has become a popular approach to estimate foot kinematics from foot worn inertial measurement units (IMUs) for walking and running. However, it remains unknown how accurate the ZUPT method is for track sprinting speeds when using sensors with characteristics (i.e., higher ranges and sampling rates) better suited for sprinting.
METHODS: 18 participants performed 70-meter track sprints while wearing a Blue Trident IMeasureU IMU. Two cameras, at 20 and 70 meters from the start, were placed to validate the ZUPT method on a stride-by-stride and on a cumulative distance basis. The validity of the method was assessed on: (1) A single stride attained at the end of the maximal speed phase, i.e., at 70m; (2) On a cumulative distance basis for the maximal speed phase from 20 to 70 meter; and (3) On total distance traveled for a 70-meter track sprint.
RESULTS: Individual stride and cumulative distance errors remained within -8 to 3% and -4 to 2%, respectively.
CONCLUSION: The results of this study demonstrate the ZUPT method is capable of yielding accurate estimates of stride length and cumulative distance traveled for sprinting speeds.
