Abstract： In response to the problems of excessive human resource consumption and insuficient accuracy in existing counting methods，a method based on YOLO detection algorithm to detect human skeletal key points for counting was proposed. This method improved the accuracy and eficiency of skeletal key points localization by improving the network structure and introducing jump connections. At the same time，the position of the lower jaw was calculated by combining the proportion of the head structure and experimental data，to achieve accurate detection of the head's position over horizontal bar. Finally，by combining skeletal key points tracking and violation detection，real-time counting was achieved. The accuracy of pullups detection reached 98.62% . The system has real-time detection，data collection，display，storage，and search functions，providing efficient and objective counting tools for sports exams.
