This study investigated the Functional Movement Screen scores attained by faster (n = 15) and slower (n = 15) male team sport athletes, as defined by multidirectional speed. Subjects were assessed in the FMS, which included seven actions: deep squat; hurdle step; in-line lunge; shoulder mobility; active straight-leg raise; trunk stability push-up; and rotary stability. Multidirectional speed was assessed by a 20-meter sprint, 505, and a modified T-test; the total time was used to median split the groups. A one-way analysis of variance (p < 0.05) determined between-group differences in the speed tests and FMS scores. Faster subjects performed better in the deep squat when compared to slower subjects (2.13 ± 0.74 vs. 1.078 ± 0.081; p = 0.001). No other screening assessment differentiated between the groups, and neither did the overall FMS score. The deep squat requires coordination and strength throughout the body, such that ankle dorsiflexion, knee and hip flexion, thoracic spine extension, and shoulder flexion and abduction, can be completed. Specific joint ranges of motion, and muscle recruitment, indicate why the deep squat was performed better by faster subjects. The deep squat could be used to screen for movement deficiencies that would affect team sport-specific multidirectional speed.
