For the purpose of determining the state and development of the aerobic ability of the male volleyball selection of Serbia, in this case the pioneer selection (the 14 - 15 category), a longitudinal study covering the period from 2000 to 2004 was carried out. The measurement of the aerobic abilities was realized during summer volleyball camp for the pioneer selections of Serbia, on a sample of 119 volleyball players aged 14 and 15, which was further divided into 5 sub-samples, where each sub-sample represented one generation of players. The comparison of the state of the aerobic abilities of all of the generations of players (2000-2004) was carried out for the purpose of gaining information on the differences between them, or to be more precise, about their development during the period selected for the study. In order to define the aerobic ability, two tests were measured, the VO2max and the VO2/TM. In order to obtain answers about the assumed differences, a canonical discriminant analysis was carried out. By analyzing the differences in aerobic abilities of all of the generations it can be concluded that during the period covered by the study, the 2003 and 2004 generations had significantly better results in comparison to the other generations, which is a clear indication of the fact that the level of this ability increased significantly during the period between 2000 and 2004. The assumption behind this increase is that the demands of these representative selections contributed to an improvement in the work on the development of aerobic abilities of the club selections, as well as the more demanding criteria of the selection for the first national team of Serbia. .
