The aim of this research is to determine the influence of the special model of explosive strength training applied on maximal mechanical strength characteristics under isometric conditions on muscle groups most involved in the game of volleyball. Eleven female volleyball players were examined for 3 days per week, over a training period of four weeks. The initial and final tests of the mechanical muscle characteristics were made under isometric conditions on four muscle groups: low back extensors, leg extensors, the calf muscles and flexors of the dominant hand. The following mechanical characteristics were evaluated: maximal muscle strength (Fmax), the time necessary for reaching maximal strength (tFmax), the rate of strength development (RFD), the impulse of muscle strength (ImpFmax) and the coefficient of the muscle activation velocity (Cmax). The tests were conducted using hardware- software systems (Program Inžinjering, Beograd consisting of a tensiometric dynamometer of high sensibility. The MANOVA (Multiply Analysis of Variance) was applied to determine variability, as well as the student t-test for small groups to evaluate the means of the obtained results. Based on the results of the MANOVA analysis, a statistically significant difference was determined (Wilk's ë 0.000358 p=0.015). The most important differences were detected in maximal strength (Fmax) and in the coefficient of the muscle activation velocity (Cmax). The results of the student t-test demonstrated that the applied special model according to the tested muscle groups, produced statistically significant differences only in the case of the calf muscles in regards to the impulse (p= 0.045), the time necessary for reaching maximal muscle strength tFmax (p= 0.004) and the coefficient of the muscle activation velocity (p= 0.031).
