Use of e-training in mathematical modeling of the biomechanical characteristics of double back somersault on the floor

Abstract

The purpose of this paper is to develop a mathematical model based on the use of e-training in the technical preparation of acrobatic elements on floor in women’s artistic gymnastics. This scientific approach has led to the organization of an experimental study, using the research methods as follows: analysis of specialized scientific literature; computerized video method by means of ”Pinnacle Studio” program of capture and video processing; also ”Kinovea” and ”Physics ToolKit” programs for biomechanical video analysis of sports technique; method of mathematical modeling; method of postural orientation of movement; statistical method, using ”KyPlot” computerized program. A number of 13 athletes aged from 12 to 15 years, all of them members of junior national team of Romania, participated in this research, which was conducted from 2012 to 2014. In this regard, 36 double back somersaults performed in three national competitions were analyzed in terms of biomechanics; the results of the kinematic and dynamic characteristics and the performances achieved in competitions were statistically correlated. It has been highlighted the linear correlative significance of the kinematic and dynamic characteristics for the translation with rotation movement, in accordance with the anthropometric, biomechanical and performance indicators of junior gymnasts of 12 to 15 years old, for developing the mathematical model of double back somersault in women’s artistic gymnastics. The effective use of e-training in the mathematical modeling of the biomechanical characteristics of sports performances created the possibility to deepen the phasic preparation of sports training and the more efficient processing of the modern didactical programs of learning.
