The objectives of the present study were: a) to assess normative profiles for the serve speed of peak-performance volleyball players in order to guide practice sessions for men´s teams and women´s teams , and b) to establish the possibilities and the ranges of speed that a volleyball throwing machine can offer for working on reception in volleyball . In studies 1 and 2, the serve techniques and the maximal speeds were analysed in men´s and women´s volleyball. Study 3 consisted of analysing the release speeds of the ball that are generated from the various speed settings that can be programmed with the throwing machine. The results provide normative profiles for the ranges of speed of the different types of serve for both men´s and women´s volleyball. Additionally, they indicate the speeds that a volleyball throwing machine provides for reception training in volleyball. volleyball – The Sport volleyball articles Journalvolleyball – The Sport volleyball articles Journal Women's opportunities for competitive physical activity were limited in America until Federal Legislation, commonly referred to as Title IX, became law. It required American society to recognize a woman's right to participate in sports on a plane equal to that of men. Prior to 1870, activities for women were recreational rather than sport-specific in nature. They were noncompetitive, informal, rule-less; they emphasized physical activity rather than competition. In the late 1800's and early 1900's, women began to form clubs that were athletic in nature. Efforts to limit women's sport activity continued as they became more involved in competitive sports. This paper will present a history of women's involvement in sport prior to the federal legislation enacted to eliminate sexual discrimination in education and sport. ABSTRACT This research presents a test of the hypothesis that there are differences in morphological characteristics, volleyball articles which affect effective realization of the elements of the game, which are influenced by many factors from the area of anthropological status of the volleyball players. The study examines the relations of body-dimensions of cadet female volleyball players and provides the answers to a question of how different are they in that segment, depending on which position in the team they play. The research was conducted on a sample of 55 female volleyball players. The sample was grouped as follows: opposites, middle blockers, outside hitters, setters and liberos. To determine the physical size differences between groups, the authors used the univariate analysis of variance , while for the precise determination of the sources of variability between groups the authors used a Post Hoc analysis, Tukey HSD test as a method of multiple comparisons. A model of physical dimensions was used, that contains the five variables: body height , range of hands , body weight , maximum reach with one hand from a place and maximum reach with two hands from a place . With this model the differences have been found in body height p=0.001 , range of hands p=0.003 , maximum reach with one hand from a place p=0.000 , and maximum reach with two hands from a place p=0.000 . Based on the results of a post hoc analysis, statistically significant differences have appeared between the group Liberos and other groups of specialists. In scientific research practice there is a lack of research of this kind. In this sense, this research is conceived as a small contribution to the advancement of the profession especially in the domain of training technologies and optimal functioning of female volleyball players in training process, volleyball articles for students
