Abstract

Abstract : Background: The Functional Movement Screen (FMS) protocol consists of 7 tests (Cook & Burton, 2014). At higher values mean higher quality of movement execution. Lower limb functional asymmetry (FA) is monitored to control the athlete's injury risk (Sannicandro et al ., 2011). Objective: To examine the correlation between the FMS score and strength asymmetry in professional soccer players (PSP). Design: Descriptive study (correlation study investigating the relationship between variables). Setting: Professional soccer. Participants: n=30 professional soccer players (age: 22.2±4.6; weight: 74.3±10, 1 kg; height: 176.1±8.7 cm), 4 players were excluded due to joint or muscle injury within the last 18 months. Assessment of Risk Factors: The FMS protocol identifies athletes as being at risk of injury when the total score is ≤14. The Hop Test (HT), Side Hop (SH) and Hop Crossover (CH) test are considered to represent a valid assessment of the single lower limb FA. The counter movement jump (CMJ) test indirectly evaluates explosive strength capacity (jump height). Main Outcome Measurements: The sample was evaluated using the 7 FMS test and CMJ, HT, SH and CH tests for strength capacity. FA was calculated between the two limbs as follows: (jump dominant limb–jump non-dominant limb)/jump dominant-limb*100 (Yamamoto, 1993). Results: We observed a significant inverse correlation between FMS score and the SH asymmetry percentage (r=−0.678, p<0.01) and the CH asymmetry percentage (r=−0.572, p<0.01). We also observed a significant positive correlation between the FMS score and CMJ values (r=0.531, p<0.01). No significant correlation was found between FMS and the HT asymmetry percentage (r=−0.245). Conclusions: The best quality movement in FMS test was correlated with high performance in CMJ and with low percentage of lower limb FA, respectively.
