Abstract

Change of Direction (COD) is a critical movement skill during athletic gameplay. In team sports like football, basketball, and rugby, the on-field performance is often assessed by the ability to change direction quickly. Optimizing the COD movement helps individual athletes reduce the risk of injury and improve skills, which results in better team strategy and outcomes. This review paper explores the algorithmic approaches investigated to date in the literature for detecting COD in athletes using wearable sensor data. Briefly summarize each algorithm's methodology and results, along with the strengths and weaknesses of their performance. An exploratory design methodology was used to search electronic databases like Google Scholar, PubMed, IEEE, and Science Direct, using predefined search phrases to identify relevant literature. The review demonstrated continuous advancements in COD detection. The review also highlighted the lack of standardized protocols for sensor placement, sampling frequency during COD movement analysis, and the limited availability of open-access datasets for COD movement, which leads to the low utilization of machine learning (ML) and deep learning (DL) models in automating the process of COD detection. Based on the identified limitations, we proposed a framework that uses Artificial Intelligence (AI) to automate COD detection. This review aims to improve COD movement detection with wearable sensors. It will help with informed decision-making and lay the groundwork for future research.
