Introduction. In modern volleyball, a competent serve is one of the important components of the volleyball game process that can make it difficult for opponents to receive the serve, while simultaneously disrupting their tactical plans. Today, the main focus in the tactical implementation of top straight serves is not only the desire to score an ‘ace’ (a clean win from a serve, after which the ball bounces correctly on the opponent's side, who is unable to touch it), but also to significantly disrupt the combination play in attacking actions.
According to existing opinions, this is achieved by varying different serves that contribute to mistakes, leading to difficulties in receiving the ball by the receiving team, as well as to the impoverishment and disruption of the tactical structure of the game and technical and tactical actions and, according to the authors, contributes to the effectiveness of technical and tactical thinking – the most characteristic features of athletes' skill, as well as tactical thinking – one of the most important strategic tasks of improving training [1].
The aim of the study is to analyse individual weekly microcycle plans and the effectiveness of volleyball players' upper straight serves during intercollegiate competitions in Volgograd.
Research results and discussion. The data of the comparative analysis of the plans of university teams showed that the individual training plan in terms of the number of sessions in a weekly microcycle for VGAFK volleyball players differed by one session from the plans of teams from other universities. The amount of time spent by VGAFK volleyball players on developing special strength endurance on exercise machines was also greater than that of teams from VSPU, VolGAU, VolgGTU and VolGU, by 4, 2, 1.33 and 1.33 times, respectively. They also spent significantly more time (50%, 87.5%, 50% and 50%) on special physical training (SPT).
Improving serves in training sessions for the VGAFK team also took 50%, 87.5%, 50% and 87.5% longer, which resulted in 84.6%, 66.1%, 109.7% and 49.3% fewer losses, respectively, compared to the university teams – VSPU, VolGAU, VolgGTU and VolGU. When assessing the technical and tactical training of volleyball players in competition conditions, it was found that VGAFK players performed upper straight serves more technically and effectively, with an emphasis on external spatial similarity to basic movements similar to developmental exercises, compared to players from other teams.
Conclusion. The results of the analysis of the technical and tactical training of volleyball players in competitions showed that the members of the VGAFK team used top straight serves more effectively. This was indicated by a 128.4%, 208.6%, 156.8% and 406.2% reduction in the number of errors compared to volleyball players from VSPU, VolGAU, VolgGTU and VolGU, respectively.
