Abstract

Purpose:
Functional movement screening tests provide beneficial information regarding the movement and stability in kinetic chain.  The core region of body, as the basis of movement chain, accounts for the facilitation of force and torque transmission. The aim of the present study was to investigate the relationship between functional movement screen composite scores and core stability muscles endurance in Taekwondoists.
Methods:
In this cross sectional study, 55 male taekwondoistwere randomly participated in the study, according to research criteria. The McGill's tests were used for the assessment of the endurance of core stability muscles. In addition, a series of functional movement screening tests were used for the assessment of the movement function of the participants. The normality of data was tested using the Kolmogorov–Smirnov test. Linear regression test at a significant level of p≤0.05 was used for the analysis.
Results:
Among the predicting variables, a significant association was found only between the endurance of right lateral flexors and the functional movement screening scores (p≤0.05). No significant association was found between the endurance of trunk flexors/extensors and the functional movement screening scores.
Conclusion:
The result of the present study showed the failure of regression model to predictthe functional movement screening scores.  In other words, the regression model could weakly predictthe functional movement screening scores (36%). Although the endurance of bodily core stability muscles is considered important for the movement function, other factors besides the core stability (e.g. the range of motion for the back, thigh and foot wrist joints) play an important role.
