Quantifying show jumping horse rider expertise using IMUs.

This study explores the use of body-mounted Inertial Measurement Units (IMUs) to quantify the expertise of horse riders in show jumping. The research indicates discernable differences in the motion patterns of experienced and novice riders.

Introduction and Aims

• In the past, the expertise of a horse rider has been gauged by the performance of the horse, the results of competitions, and visual observation. Recent advancements have introduced scientific methods to measure the ability of a horse rider, focusing on aspects like the positioning angles and the harmony in the system of the horse-rider.
• This study is unique as, for the first time, it attempts to quantify the rider’s abilities specifically in the sport of show jumping. The technique revolves around the usage of kinematic analysis and motion sensors, a methodology previously employed in sports other than show jumping to assess the qualities of motor control patterns in human beings.

Methods

• The core component in the methodology of this research is the Inertial Measurement Unit (IMU). The IMU is a device that measures the velocity, orientation, and gravitational forces by detecting changes in the linear and angular motion. In this study, these IMUs were body-mounted i.e., attached to the body of the participant riders.
• With the IMUs attached to their bodies, the riders completed show jumping courses. The resultant data from the IMUs allowed researchers to examine motion patterns associated with the horse riding activity and quantify rider ability in the context of show jumping.

Preliminary Findings

• The study’s initial findings suggest that there are distinct differences in novice and experienced riders during show jumping.
• These differences can be traced in the recorded motion patterns, providing a quantitative measure of the riders’ abilities and skills.
• Such results underline the potential of utilizing IMUs as a valid tool for assessing rider ability, not only for scientific research but potentially for training and competition as well.
