YOLO Algorithm in Analysis and Design of Athletes’ Actions in College Physical Education

This article designs an action analysis system based on the YOLO (You Only Look Once) algorithm, which can collect video information through sensors and perform feature extraction. Based on the extracted feature extraction model, this paper uses the YOLO algorithm to detect and recognize moving targets in videos, and converts the recognition results into corresponding labels. These labels can be fed back to the trained YOLO model to analyze actions. The results indicate that the action analysis based on YOLO algorithm studied in the article can effectively improve the fluency and safety of students’ actions.
