Although absolute jump heights should be considered an important factor in judging the performance requirements of volleyball players, limited data is available on age-appropriate categories. The purpose of this study is to determine the differences in specific anthropometric characteristics and jumping performance variables in under−19 female volleyball players in relation to playing position and performance level. The sample of subjects consisted of 354 players who prepared for the U19 Women’s Volleyball European Championship 2020 (17.4 ± 0.8 years, 1.81 ± 0.07 m, 67.5 ± 7.1 kg). Playing positions analyzed were setters (n = 55), opposites (n = 37), middle blockers (n = 82), outside hitters (n = 137), and liberos (n = 43). The results showed player position differences in every performance level group in variables of body height, spike, and block jump. Observed differences are a consequence of highly specific tasks of different positions in the composition of the team. Players of different performance levels are significantly different, with athletes of higher-ranked teams achieving better results. The acquired data could be useful for the selection and profiling of young volleyball players.

The beginnings of Sokolism bind to the second half of the 19th century, namely to the Czech Miroslav Tyrš and its system of physical exercise. After the founding in the Czech Republic, Sokol movement began to spread in all Slavic countries as well as in those where Slavic nations lived. In this way, Sokolism arrived among Serbs who lived in America (USA), and they began to accept the idea of Sokolism in the mid-1907. In early 1909 began to appear the first initiatives for the establishment of Serbian Soko Societies. During 1909 two societies were founded, the in the next year five more, in 1911 three societies and in 1912 more than ten. In the second half of 1911 was established the union of Serbian Soko societies in America called Serbian Soko Parish in America (SSPA). Serbian Soko Society in Cleveland, Ohio, which is also the main subject of this research, was founded in the first half of 1912. The aim of the authors is to explore and present the exact date of the founding of this Society, the main initiators and founders, members and activities of the Society during its work. In this study authors used the historical method.

At the end of the 19th century in the Czech Republic a new way of physical exercise entitled the “Sokol” or “Tyrš” system appeared. It spread to all the countries where Slavs lived and thus arrived among the Serbs who lived on the territory of Bosnia and Herzegovina. A group of Serbs from Foča in 1893 tried to establish the Serbian Soko society but the Austro-Hungarian authorities did not allow it. The first Serbian gymnastic society on the territory of Bosnia and Herzegovina called “Obilić” was founded in 1904 in Mostar. Many educated people of that time participated in the work of the Soko organizations, among them the medical doctor Branko Čubrilović. The main subject of this paper is Branko Čubrilović and his connections with Serbian Sokolism and the aim is to highlight his role in the development of Serbian Sokolism, primarily in the areas of Bosnia and Herzegovina, as well as in other areas where Serbs lived. The authors used a historical method.
