Abstract :

The purpose of the present study was firstly to investigate the effect of static stretching on female volleyball players kinematics characteristics during volleyball spike from the back row defense, in position 1. Twelve female volleyball players (age 18–21, training age 6–10 years, height 178.17} 3.15 cm and weight 65.90 } 5.80 kg), volunteered as participants and they were randomly divided into two groups of 6 players. The exercise protocol involved a 5 minutes general warm–up, followed by the initial spike, followed by the static stretching of the upper limbs and followed by the final spike. The kinematics characteristics of the players during the initial and final spike, into 2 times (T) and 1 phases, were evaluated by a three–dimensional (3D) vinteoanalysis APAS. Paired t–test and Wilcoxon analysis showed significant difference and increase after the static stretching, of the right wrist displacement (DRWr) at the T 2 and 4 (p=0.014, p=0.039), of the left wrist displacement (DLWr) at the T 3 (p=0.012) and of the right wrist range of motion (RomRWr) at the first phase (p=0.037). Significant difference and reduction, after the static stretching, was found of the left shoulder angular velocity (VLSh) at T 4 (p = 0.024) and of the right wrist (VRKarp) at T 4 (p = 0.008, p = 0.017). No difference was observed on the kinematics characteristics of the lower limbs, on the total displacement (D) and the velocity of the center of body mass (CM), on the jump height and the speed of the ball. It is concluded that the volleyball players should avoid static stretching before the competition.
