The aim of this paper is to define a simple mathematical model for estimating general
jumping preparedness of senior female volleyball players (SCOREpoint) by applying a set of 7
variables measured by standardized tests within the field measuring conditions. The sensitivity of
this model is determined on the basis of achieved points and differences in general jumping
preparedness among female volleyball players competing in elite international competitions, elite
national competitions, state-level and regional-level competitions. Applied battery of tests has
cumulatively explained 80.64% of the total variant of measurement. The defined model
explained the criterion of general jumping preparedness of senior female volleyball players at the
level of 100% (Adj. R2 = 1.000), and with the minor error in prediction (Std. Err. Est. = 0.003
SCOREpoint points). The obtained model has the following form: SCOREpoint = -86.762 +
(0.4595 · CMJARM + 0.5158 · CMJNOARM + 0.4620 · SJCONARM + 0.4812 · SJCONCNOARM + 0.5431 ·
CMBJ + 0.5626 · SJCONCBJ + 0.138 · SLJ. The defined model has a satisfactory level of
discrimination and it is proposed for further practical use.
