Development of 3D motion measurement system for sport climbing

Abstract

Sport climbing is one of the sports attracting attention all over the world and expected to become more popular. Therefore, motion measurement and analysis system have been required to improve the performance of players and instruct them. In several researches, the systems on motion measurement and analysis of climbing have been presented. Most of these systems consider only the movement of climbing, and take no thought of the force on holds. However, force information is indispensable to analyze the body motion of players deeply. This paper proposes a new 3D motion and force measurement system for sport climbing that can measure the movement and the force on holds simultaneously. Then, this proposed system enables us to measure and analyze climbing motions geometrically and dynamically. In order to verify the performance of the proposed system, we conducted the experiment in an actual climbing gym. In addition, we analyzed the center of mass of a player and the force on a hold by using the proposed system.
