The current paper presents the results of a study which aims to emphasize the correlations established between the take-off assessment indices. The assessment was performed with the "15 jumps test" based on the "modified Miron Georgescu method". The study group included 10 female athletes, senior volleyball players and members of the volleyball training team. The results were processed, analyzed and graphically represented. The conclusions pointed out the fact that the take-off height using both legs has an average value of 35 cm and extreme values of 38 and 32 cm, the left leg take-off has an average value of 19 cm and extreme values of 22 and 14 cm, and the right leg take-off has an average value of 18 cm and 21 and 15 cm as extreme values. Positive linear correlations were established between the values of the average flight height and average power-to-weight ratio, of maximum accomplished power-to-weight ratio, and maximum possible power-to-weight ratio, and they ranged between 0.723 and 0.966. The values of the linear correlation for the take-off test using the left leg were closer to 1 and they ranged between 0.966 and 0.844, in comparison with the ones using the right leg, which ranged between 0.825 and 0.723.
