The Effect of Core Stability Exercises on Lower Limb Alignment, Upper and Lower Limb Function in Kyokushin Girls

Background: The purpose of this study was to investigate the effect of core stability exercises in the trunk area on lower limb alignment and lower and upper limb function in Kyokushin athletes. Methods: The statistical sample of the research consisted of 30 female kyokushin players aged 14-18 years, who were randomly divided into two control and experimental groups. The control group performed common Kyokushin exercises and the experimental group performed core stability exercises for 6 weeks. Analysis of covariance and correlated t tests were used to compare between groups and within groups. Results: The results of the correlated t-test showed a significant effect of training programs on changes in upper and lower limb function in both control and experimental groups (P≤0.05), however, in both control groups and experimentally significant difference between pre-test and post-test The test was not observed in the Q angle (P>0.05). The results of analysis of covariance test showed that after controlling the effect of pre-test, there was a significant difference in lateral jump (P≤0.05) between the control and experimental groups. However, there was no difference between the two groups in the changes of CKCUEST, square jump and Q angle (P>0.05). Conclusion: Considering the nature of Kyokushin and the research results, it is suggested that people who work in Kyokushin do not feel the need for core stability exercises separately.
