Factorial Structure of Basic Kinetic Elements

Quantitative and qualitative diversity of expressing basic kinetic elements in the kinetic structure is manifested in overcoming resistance on a certain path in certain time. Basic kinetic elements – time (s), amplitude (m) and resistance (kg), with their distribution and configuration determine the efficiency and type of the kinetic structure and enable the observation of those elements with other anthropological areas. The basic goal of this research is directed towards defining the latent structure of basic kinetic elements with the help of a specially prepared instrumentarium, with the use of the ergometrical method and on the basis of a factorial analysis of the elements of resistance, amplitude and time in individual and repeating motion. The quality and the degree of correlation between basic kinetic elements was determined and a factorial structure was obtained for 124, 15-years-old, male respondents. Considering the type of research, this sample can be considered representative. A total of 21 kinetic measures, obtained with the use of instruments and the use of ergometrical method, were used for evaluating basic kinetic elements. Variables were chosen in such a way that they hypothetically cover basic kinetic elements in kinetic structures manifested in individual and repeating movement, defined as time dimensionality of the kinetic structure and tensodynamic dimensionality of the kinetic structure. For a better insight into the general behavior of analyzed variables, the methods of data processing were encompassed through calculation of regresional analysis series, so as to determine the complex and the latent structure of basic kinetic elements (factorial analysis Little Jiffy, Mark IV was used). The analysis of the factorial structure of basic kinetic elements was carried out in a manifest area of variables. Six factors have been extracted on the basis of characteristic vales of the matrix of covariance of the analyzed space with the use of Guttman ¬Kaiserov criterion. Isolated factors in this area have a phenomenological determination: 1. Latent dimension of pulling in kinetic structure (defined with resistance, amplitude and time in kinetic task - pulling) 2. Latent dimension of pressing in kinetic structure (defined with resistance, amplitude and time in kinetic task - pressing) 3. Latent dimension of repeating in kinetic structure (defined with resistance, amplitude and time in kinetic task - repeating) 4. Latent dimension of accumulating and releasing of energy in kinetic structure (defined with resistance, amplitude and time in kinetic task) 5. Latent dimension of generating and releasing energy in the kinetic structure (defined with resistance within kinetic tasks realized in individual movement) 6. Latent dimension of special determination of the kinetic structure (defined with the amplitude within kinetic tasks realized in individual movement). The latent structure of basic kinetic elements was analyzed. Latent kinetic dimensions were extracted and interpreted as mechanisms for regulating intensity of exitation, a mechanism for regulating synergy and regulating muscle tone and integrative mechanisms for regulation, control and coordination of the mentioned regulative subsystems in the kinetic structure.
