The Effect of Static Stretching in the Initial Part of the Attack Spike Movement in High Level Female Volleyball Players
he purpose of this study was to investigate the effect of static stretching on kinematics characteristics of female volleyball players during the initial part of the movement of the attack 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 attack spike. After the first measurement, participants execute static stretching of the upper limbs and the final spike. Kinematic characteristics of the players during the initial and final spike, divided into 2 times (T) and 1 phase, were evaluated by a threedimensional (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.
