The aim of this study was to investigate biomechanical variables of elite male volleyball attackers and determines if differences exist in these characteristics between opposites, middle blockers and outside hitters. A group of 24 professional male team volleyball attackers participated in the study (age: 29.5 ± 2.6 years). Biomechanical characteristics including lower body power (CMJ), maximal dynamic strength of upper and lower body (Squat 1- RM and Bench Press 1-Rm) and agility were evaluated in all the subjects. Opposite attackers have the highest records of all biomechanical variables and middle blockers have the lowest, except in agility which belongs to outside attackers. There are significant differences between Squat, Bench Press and countermovement jump in different groups of attackers. No other significant differences were observed in agility results. Considering biomechanical variables related to performance in each position seems to be essential. Training session should be focused on improving middle blockers physical characteristics and different agility trainings should be designed for attackers due to their movement pattern.
