Relationships between core stability, sex, and functional movement


Purpose: To examine relationships between sex, core stability endurance (CSE), and movement capacity in healthy, active adults. Methods: Fifty-three adults performed the functional movement screen (FMS) and CSE tests (extension, flexion, and right/left side bridge) during the current study. A generalized linear mixed model with random effects was used to identify interactions between sex, CSE, and FMS composite scores. Results: There was a significant triple interaction between CSE test, CSE score, and sex (P < .001), indicating the relationship between CSE test scores and FMS differed by CSE test and sex. Analyses of each CSE test found significant interactions between sex and FMS scores for the CSE extension and right side bridge tests. CSE extension and right side bridge accounted for 43% and 40% of the variance in FMS composite scores in women, compared to 9% and less than 1% in men, respectively. Conclusions: CSE appears to contribute more to the movement capacity of women than men.
