Running analysis device, running analysis method and running analysis program

摘要

PROBLEM TO BE SOLVED: To estimate a user's ground contact timing during running by using an acceleration sensor mounted on a user's head or neck. A running analysis device 100 is a running analysis device 100 that analyzes a user's running based on sensing data acquired from a motion sensor including an acceleration sensor mounted on the user's head or neck. Acquires Z-axis acceleration data AccZ corresponding to acceleration in the direction perpendicular to the user's traveling direction and Y-axis acceleration data AcccY corresponding to acceleration in the opposite direction of the user's traveling direction detected by the acceleration sensor during running. Then, based on the Z-axis acceleration data AccZ, a candidate range R that is a candidate for the user's grounding timing is set, and the user's grounding timing is set based on the timing at which the value of the Y-axis acceleration data AccY is the lowest in the candidate range R. presume.
