Abstract
The aim of the research was to determine in which stage are theoretical preparation procedures by interviewing coaches and cadet girl players. The research has been conducted among 196 girl cadets (born in 1991 and after) and 37 coaches from Belgrade clubs and local Belgrade municipality clubs. Appropriate statistic procedures applied (descriptive and comparative analysis) gave the following results: the majority of coaches and players agree that theoretical preparation during training procedures is important for the success; theoretical preparation is to be started with pre-cadet and even at younger age; most of the coaches (70%) use theoretical preparation during the practice, where as training aside the practice is considerably less applied; under the opinion of coaches, great number of girl players accept this training procedure very well and take part in it; the players consider that this procedure could possible be more interesting, but nevertheless, the majority of them does not want anybody else apart from their coaches to conduct the theoretical preparation. General conclusion is that theoretical preparation while training girl volleyball players is satisfactory, but that further development or constant practice during training processes are slowed down by material and technical conditions of clubs as well as coaches' expertise level.
