METHODOLOGICAL PRINCIPLES OF SELECTION IN SPORTS

The selection process in sport includes the most diverse characteristics and dimensions for assessment and evaluation. Only by adequately combining genetic, physical, morphological-functional, psychological, pedagogical and sociological dimensions, the conditions necessary to define selection as a multidisciplinary science, which can provide prerequisites for achieving the set goals are gained. If we look at selection as a limiting factor that connects a certain sport with biological sciences on the one hand, and with the humanities on the other, creating a unique professional-scientific principle within such differentiated sciences, it carries enormous difficulties. That's reason why theoretical and professional - research and practical work in selection is exposed to great risks, which require overcoming problems that constantly arise during work. Therefore, it is necessary to minimize all the demarcations that exist in different fields, while increasing the cohesiveness between the principles that operate within the framework of different scientific disciplines. The end result of this approach should be the synthesis of different knowledge and their transfer into one general, comprehensive framework. In this paper will be presented the methodological principles of selection in sports from the perspective of: models and model characteristics, tests as selection monitor instruments, prognosticate and evaluation of physical abilities testing results, growth and the process of maturing, psychosocial characteristics with special reference to genetic basis of physical abilities and morphological characteristics.
