Dynamic Analysis Of Changes Of Body Movement Difficulty In Rhythmic Gymnastics

The sports rhythmic gymnastics is a sport guided, influenced, restricted by the rule. Meanwhile, it is the source of promoting the rule to develop and improve constantly. They are the subjects of a pair of contradictions, developing and improving forward constantly in mutual contradiction. The body movement difficulties are the essential features of the sports items of rhythmic gymnastics, and the backbones of a set of movements, and they are regarded as the breach of the technical development of rhythmic gymnastics all the time and guide the development of the technology of rhythmic gymnastics. Therefore, we will treat the body movement difficulty with the eyes of development, and understand and appreciate them deeply. In this way, we could develop better innovate body difficulty movement to catch up with the world level of rhythmic gymnastics.This research takes the rule with the rhythmic gymnastics which adds up to 8 editions during 1976-2005 and the athletes of the top 8 of world rhythmic gymnastics championship in 2001, 2003 and 2005 as the research objects. Through a large number of materials from the school library and Chinese periodical network about body movement difficulty of rhythmic gymnastics, it analyzes the rule of marking of rhythmic gymnastics and match video of the top 8 of world rhythmic gymnastics championship in 2001, 2003 and 2005, and finally counts the collected mathematical statistics through computer. It analyzes the rhythmic gymnastics body movement difficulty quantity, type, score, rank of movement and concludes all kinds of body movement difficulty quantity, evaluation criterion combining other body movement difficulty situation.The result of study indicates that the development of the body movement difficulty of rhythmic gymnastics has the dynamic change characteristics. It establishe.s and fixes four body movement difficulty types- the step of jumping, equilibrate, turn, not pliable and tough from the aspect of movement type; it develops into more than ten grades at present from two initial grades from the aspect of movement rank of difficulty of the body; the movement quantity of all kinds of difficulty is on the rise, and the quantity of increase presents the wave change in the rule; the evaluation criterion of all kinds of difficulty is more and more difficult too; technology of all kinds of difficulties combine among each other.We can find out that the use of the movements of difficulty of all kinds of health is being developed in the balanced direction and the rate of utilization of the movements of difficulty of the medium-sized rank body has been occupying high all the time through an analysis .of world rhythmic gymnastics championship. Pliable and tough / wave is more advanced than the other movement type of difficulties. The innovation of body movement difficulty of rhythmic gymnastics has many types and methods, the formulation of the rule is motive force of the rhythmic gymnastics innovation. The innovation of body movement difficulty of the rhythmic gymnastics concentrates on the original and ingenious combination of many kinds of technologies.This research offers some certain theory to consult in developing direction of movement in pursue international rhythmic gymnastics body movement difficulty. It can make us understand the development of body movement difficulty of rhythmic gymnastics and innovative trend within a new cycle as soon as possible. It aims at offering the theoretical foundation for development and training for the rhythmic gymnastics of our country.
