INTRODUCTION AND MOTIVATION
Racket validation using IMUs has been explored, supported by 3D camera systems to analyze stroke dynamics. The aim is to capture acceleration during striking and better understand movement patterns in sports such as tennis, padel and hockey.
DEVELOPED PROTOTYPE
An inertial measurement system has been implemented by placing IMUs on both the forearm (near the wrist) and the racket. This setup allows the comparison of acceleration data during stroke execution.
SPECIFIC OBJECTIVES
Our research focuses on analyzing high-speed movements in racket sports using inertial sensors
AI Implementation
Study of forearm and equipment acceleration during striking using IMUs placed on the forearm and racket.
PC Application
Deployment of a robust technique analysis software suite for researchers and coaches.
Feasibility in Different Sports
Evaluation of the system in tennis, padel, hockey and rowing to determine its applicability and future improvements.
RESULTS AND CONCLUSIONS
Tests in tennis, padel and hockey showed limitations due to insufficient gyroscope dynamic range, causing sensor saturation and preventing reliable analysis. In rowing, preliminary results were promising, although improvements in system sealing are needed.
Overall, current hardware limits full technique recognition.
