Training tasks intensity criteria for the physical advance of students playing volleyball

The research was aimed at defining the optimal parameters and criteria of intensiveness of training tasks for students going in for volleyball during physical training lessons. The students of Sevastopol State University (n = 81; age 18±1 years old; body mass 69,1±0,4 kg; height 177,5±0,4 cm; VO2max 51,5±0,24 ml/min/kg ) took part in the research. The research methods included: scientific and methodical sources analysis, physiometry, control tests and mathematical statistic methods. As a result volleyball training tasks were been classified according to the level of coordinational complexity. Reactions of the cardiovascular system of students while doing volleyball exercises were been defined. Volleyball training tasks with different levels of coordinational complexity were been developed. The relation between the intensity of volleyball exercises with different levels of coordinational complexity and the zones of metabolic power of the load (VO2max, %) were been obtained. The intensiveness parameters of training tasks (the duration of the task, the duration and type of the rest period and the number of cycles in a task) for students playing volleyball during physical training lessons were been calculated. Approbation of the developed program of lessons during one term (34 lessons) showed positive changes in the level of fitness and technical skills of students. The results of the research allow to control the process of physical improvement of volleyball students more effectively.
