Asymmetry or a low FMS individual test score was a better predictor of MSI than the composite FMS score.

Changes in many aspects of physical capacity and athletic performance have been documented through the course of a competitive season in collegiate athletes. Movement pattern quality as measured by the functional movement screen (FMS) has recently been linked to performance and injury risk. The purpose of this study was to document the changes in functional movement patterns over a competitive season. Fifty-seven National Collegiate Athletic Association Division II athletes were screened using the FMS as part of the pre and post participation examination for their competitive seasons in 2012. Composite and individual FMS test scores for the preseason and postseason were compared with identified significant changes. The scores were also analyzed for changes in the number of asymmetries present and the frequency of a score of 1 in any of the tests. There were no significant interactions in the main effects for time or sport in the composite FMS scores. However, 4 individual tests did show significant change. The deep squat (Z = -3.260, p = 0.001) and in-line lunge scores (Z = -3.498, p < 0.001) improved across all athletes, and the active straight leg raise (Z = -2.496, p = 0.013) and rotary stability scores (Z = -2.530, p = 0.011) worsened across all athletes. A reduction in the number of asymmetries (χ = 4.258, p = 0.039) and scores of 1 (χ = 26.148, p < 0.001) were also found. Changes in individual fundamental movement patterns occur through the course of a competitive season.

BackgroundPoor balance, lack of neuromuscular control, and movement ability are predictors of performance and injury risk in sports and physical activity participation. The Functional Movement Screen™ (FMS™) and lower quarter Y-Balance Test (YBT) have been used by clinicians to evaluate balance, functional symmetry, and static and dynamic movement patterns, yet little information exists regarding the relationship between the FMS™, YBT, and physical performance tests (e.g. vertical jump) within the high school population. PurposeThe purpose of this study was to investigate the relationship between the FMS TM , dynamic balance as measured by the YBT and physical performance tests (standing long jump, vertical jump, Pro Agility Test) in male and female high school athletes. Study DesignCohort study. MethodsFifty-six high school athletes (28 females, 28 males; mean age 16.4 ± 0.1) who participated in organized team sports were tested. Participants performed the FMS™, YBT, and three physical performance tests (standing long jump, vertical jump, Pro Agility Test). ResultsFemales outperformed males on the FMS™ and YBT, while males outperformed females on the performance tests. In both sexes, the composite FMS TM score was positively correlated with the left and composite YBT scores. Agility was negatively correlated with composite FMS TM in males (p < 0.05) and the left and composite YBT in females (p < 0.05). ConclusionsThe FMS TM and YBT may evaluate similar underlying constructs in high school athletes, such as dynamic balance and lower extremity power. The results of this study demonstrate the utility of the FMS and YBT to relate multiple constructs of muscular power to an individual's ability to balance. Furthermore, establishing the need for the utilization and application of multiple field-based tests by sports medicine professionals and strength and conditioning coaches when evaluating an athlete's movement and physical performance capabilities. Utilization of multiple field-based tests may provide the first step for the development of injury prevention strategies and long-term athlete development programs. Level of Evidence2b.
