چکیده:
Introduction: This study aimed to investigate the effect of a 4-week core stability training program on landing kinetic parameters in athletes with functional ankle instability during a single-leg drop landing exercise. Methods: This study used a pre-post quasi-experimental design and was conducted in the biomechanics laboratory. A total number of 24 athletes with functional ankle instability participated in two experimental (n=12) and control (n=12) groups. The experimental group performed core stability training for 4 weeks. The kinetic variables (maximum vertical Ground-Reaction Force [GRF] , maximum shear GRF, and time to peak vertical GRF) were measured with force plate at the frequency of 400 Hz, in the pre-test and post-test. The obtained data were compared using Analysis of Covariance (ANCOVA) and multivariate analysis of covariance MANCOVA in SPSS V. 18. Results: In the experimental group, all variables significantly differ between the pre-test and post-test. Also, the ANCOVA and MANCOVA indicated significant differences between the experimental and control groups in all variables. Conclusion: The results indicated that the core stability training improved the kinetic parameters of landing in people with functional ankle instability; thus, it can reduce the re-injury risk of the ankle.

These researchers stated that the core stability training reduced the vertical force of ground reaction and improved landing kinet- ics; this training program may reduce the risk of lower extremity injury among female athletes [21].
Therefore, the goal of the present study is to evaluate the effect of the four weeks of core stability training on landing kinetics in in- dividuals with functional ankle instability.
Particularly, the two groups significantly differ in the time variations of the performing of the McGill trunk tests (P Discussion The purpose of this study was to investigate the effect of a 4-week core stability training program on the maxi- mum vertical GRF, the maximum shear GRF, and the time to peak vertical GRF, in individuals with functional ankle instability during the single-leg drop landing task.
