Analysis of the impact of morphological characteristics on situational-motor abilities of sitting volleyball players was applied on the sample of 90 examinees, registered players of Premier League of Bosnia and Herzegovina in sitting volleyball, and among of them it was fifteen representatives of Bosnia and Herzegovina. In this research is applied a set of battery test which contains 23 variables in which 15 variables are of morphological characteristics and the system of 8 variables for assessing situational-motor abilities of sitting volleyball players. The aim of this research is was to prove which is the impact of morphological characteristics of sitting volleyball players, and what impact these have on certain characteristics of situational-motor abilities of sitting volleyball players. We performed a regression analysis of the first criterion variables of situational-motor abilities in manifest space morphological variables of sitting volleyball players. Morphological characteristics applied in the system of predictor variables, four significantly affect on the results of situational motor tests which respectively means that in test isolated regression situational factors of motor abilities. The research results indicate that the players who have more arms length, the width of the pelvis, upper arm circumference, lower abdominal skinfold will affect and make an advantage in the implementation of situational-motor abilities.
