Motion Measurement System for Sport Climbing using Force Sensors

Abstract

Sport climbing is one of the most popular sports and was adopted as a new official sport at Tokyo Olympic 2020. Players climb walls with holds in this event. Movements and postures of climbers have a tendency to become complicated compared with other sports due to a wide variety of holds and walls. Therefore, it is difficult to measure and analyze the whole body motion of climbers precisely. This paper shows multiple force sensing systems that measures the force applied to holds by climbers. A typical movement called “Dyno” is focused on in this paper. Dyno is all out leap using whole body to reach the next hold. In this paper, the dyno movements are measured by four force measurement systems incorporating six-axis force sensors. The subjects of the experiment are nine advanced and eight intermediate climbers. As a result, some differences between the advanced and intermediate climbers are shown.
