TY - JOUR JF - USWR JO - PTJ VL - 13 IS - 2 PY - 2023 Y1 - 2023/4/01 TI - The Effect of Core Stability Exercises on Lower Limb Alignment, Upper and Lower Limb Function in Kyokushin Girls TT - N2 - Purpose: This study was conducted to investigate the effect of 6 weeks 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 included 30 female Kyokushin players aged 14-18 years, who were randomly divided into two experimental and control groups. The control group performed common Kyokushin exercises and the experimental group performed core stability exercises for 6 weeks. Analysis of covariance (ANCOVA) and paired t-tests were used to compare between groups and within groups. Results: The results of the paired t-test showed a significant effect of training programs on changes in upper and lower limb function in both experimental and control groups (P≤0.05); however, a significant difference was observed between the pre-test and post-test in both control and experimental group. The test was not observed in the Q angle (P>0.05). The results of ANCOVA test showed that after controlling the effect of the pre-test, a significant difference was observed in lateral jump (P≤0.05) between the experimental and control groups. However, no difference was observed between the two groups in the changes of closed kinetic chain upper extremity stability test (CKCUEST), square jump, and Q angle (P>0.05). Conclusion: Considering the nature of Kyokushin and the research results, it is suggested that people working in Kyokushin do not feel the need for core stability exercises separately.
