Rumba open point turn technical analysis based on human motion mechanics

摘要

Rumba is a multi-point turn action sports project. In rumba point turn process; there are often some wide-angle rotating actions, which are of certain degree of difficulty for beginners, such as the turnover after the Latin cross step. How to solve these difficult movements becomes the focus of attentions of many coaches and athletes. This paper uses the theory of human motion mechanics to analysis the dynamics principle in the rumba open point turn process, respectively analysis the open point turn action technique in the six-step process for both men and women dancers. Then it studies the cause of body standing instability after rotation, gives improvement methods for the body destabilizing factors during or after the rotation, and provides a theoretical basis for rumba open point turn technical training.
