Title:
MEASUREMENT SYSTEM USED TO ANALYZE MOTION TRAJECTORY OF KNEE JOINTS DURING BICYCLE CYCLING, AND METHOD OF THE SAME
Document Type and Number:
Japanese Patent JP2015091311
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a measurement system used to analyze a motion trajectory of knee joints during bicycle cycling and a method of the same which can analyze the motion trajectory of the knee joints during the cycling easily and quickly.SOLUTION: A measurement system 14 includes at least: a pedaling device; a light-emitting member; an image intake device; and a knee joint motion trajectory analyzing device. When a rider performs pedaling with the pedaling device, the image intake device takes in an image showing a central position of lower limbs of the rider during pedaling and an image showing a light spot trajectory of the light-emitting member when the rider is pedaling. A motion trajectory analyzing module 145 generates an elliptical motion trajectory diagram, and obtains deviation data of the motion trajectory of the knee joints and pressure distribution received by soles during cycling after performing a comparative analysis of a body center line as a base and a trajectory long axial line of the elliptical motion trajectory diagram.
