BIOMECHANICAL STATUS AND STRUCTURE OF EXERCISES FOR FUNCTIONAL STAGE AND THE FIRST STAGE OF KYPHOSIS

The need for a scientific approach in the creation and the selection of complex exercises for functional and the first stage of kyphosis from different initial positions by use of props and equipment is essential and indispensable. The importance of this study is great, having in mind the fact that the rate of bodily deformities is quite high and tends to increase steadily. Starting from the need for a scientific approach in the creation and the selection of complex exercises for the functional and the first stage of kyphosis that are present among the school population is more than necessary. The importance of interdisciplinary character of biomechanics and its subject of interest and research in this study is presented through application of a qualitative biomechanical analysis which is conducted from several aspects of complex exercises for kyphosis, functional stage and first degree of deformity. Among other things, qualitative biomechanical analysis enables registration of changes that occur in the spine at different periods of growth and development of children. In particular, the pathological changes of the postural status that hinder the manifestation of motor skills and habits in the course of the physical and health education, as well as among those children who are actively engaged in sports. The research includes 12 exercises for strength of the postural muscles from different initial positions by use of props and equipment (functional stage and the first degree of kyphosis). The exercises are analyzed by the method of qualitative biomechanical analysis, algorithm ALPROBI and then processed by factorization of the matrix of inter-similarity by use of the method of the main components by the software package SPSS28 From the obtained results from this study it could be stated that the application of the exercises: Torso lifting from kneeling position with elbows bent at 90 degrees .908, Torso lifting from chest lying .952, Stretching the back muscles with hands on the bar.905. and their more frequent application throughout the training process both on daily and weekly basis would bring to more benefits and efficacy.
