Investigating the Effect of 8-Week Central Stability Training Program on Jump-Landing Pattern and Balance of Active Students with Trunk Problems

The purpose of the present study was to investigate the effect of 8 weeks of coherent central stability training program on the jump-landing pattern and balance of students with trunk defects. The statistical population of this research included all students of Imam Khomeini Naval Academy in Nowshahr. 30 students with trunk defects were selected as a statistical sample of the research through the double leg jump test and were randomly assigned to two control and training groups. In order to evaluate the static and dynamic balance, the Stork and Wai tests were used, and the jump-landing error was evaluated with the landing error scoring system test. Then, the training group performed consistent central stability exercises for 8 weeks and three sessions per week. All the subjects of the training group completed 24 training sessions and the subjects of the control group did their general activities during this period. The post-test was done like the pre-test and post-test. Ancova test was used to compare the differences between the research variables due to the application of the exercise program, and the correlated t test was used to evaluate the changes within the group. All statistical analyzes were performed using SPSS version 24 software. The results showed that there is a significant difference between the two groups in the results of landing error score (P<0.001), static balance (P<0.001) and dynamic balance (P<0.001) in the post-test between the two groups (0.05). ≥P). According to the obtained results, it seems that central stability exercises can be effective in improving the balance and landing jump pattern, thus reducing the risk of injury.
