A comparison of the instantaneous effects of spinal manipulation and mobilization techniques applied to L3 level on jumping, agility and sprint speed in male volleyball players

The aim of this study is to investigate the effect of manipulation and mobilization treatments to be applied to the L3 segment on sportive performance in order to prevent athletes' performance anxiety and low performance due to competition stress. Sixty people between the ages of 18-25 participated in the study. They were randomly divided into 3 groups as manipulation group, mobilization group and control group. After the participants performed the necessary warm-up program, manipulation or mobilization was performed in accordance with their groups. Hip range of motion, lumbar range of motion, T-Test time (seconds), 10-meter sprint time (seconds), vertical jump (cm), horizontal jump (cm) were measured instantaneously before and after the interventions. Significance was evaluated as p<0.05. There was no significance between the groups in terms of age and height of the participants (p>0.05). The group with the highest mean body mass index and weight was the mobilization group (p=0.05). In the comparision made within the group, the data except vertical jump, hip flexion, hip extension and hip adduction were statistically significant (p<0.05). In the comparison between groups, the data except hip flexion, hip adduction, hip internal rotation and lumbar lateral flexion were statistically significant (p<0.05). When we compared the data between the groups, it was seen that the spinal manipulation group was superior to the spinal mobilization and the control group. We are of the opinion that especially pre-competition applications will provide the best benefit for volleyball players. Keywords: Spinal Manipulation, Spinal Mobilization, Sport Performance
