The AI Coaching Assistant (ACA) project aims to create a self-supervised athlete performance tracking system for Olympic weightlifting. The project is co-sponsored by Gymshark and Aston university. Using the combination of visual data (continuous camera feed) integrated with heart rate variability and direct coach and athlete feedback, ACA project is developing models for predicting performance and fatigue levels throughout training to reduce the risk of overtraining and injury. This is a novel approach where the developed software is intended to be used throughout all of the training partaken by the athletes, giving a greater insight to the athletes performance and the ability to track and predict their progression. The project is currently running the first main data collection study at Warley weightlifting club in Birmingham, for participation and further project details visit https://aicoachingassistant.github.io/
