In this paper, we analyze the rings sports based on biomechanics. First, the rings movement is divided into four phases and two stages by using the rings five basic movement characteristics and situation of muscle force. Then analyze the characteristics of rings technology for the two stages using the principle of dynamics. Finally, analyze the characteristics of rings movement force value biomechanical parameters through force-measuring curve value data captured by measurement equipment and summarized the technical causes in all stages of force. This article methods and results analysis provides certain theoretical for our country's rings movement.
