INTRODUCTION: Functional movement screen (FMS) involves several tests aimed at classifying basic movements used to qualitatively determine movement weaknesses and asymmetries, that modify motor control. Additionally, the range of motion (ROM) measured by goniometry is a quantitative method used in clinical settings to determine normality, symmetry, limitation or excess of a particular joint movement. PURPOSE: To identify the relationship between functional movement screen and goniometric assessment of active mobility of the shoulder, hip, knee and ankle, in young athletes. METHODS: Forty four healthy young athletes (age 14.34 ± 1.12 y), who take part in the National Talent Program of Coldeportes, were evaluated using 5 FMS tests and 6 ROM tests (active movement) for the shoulder, hip, knee and ankle. Correlations were calculated through Spearman coefficient. RESULTS: No significant correlation was found for shouder (r=0.005; p=0.52), hip (r=0.04; p=0.43) and ankle (r=0.14; p=0.35) movements. A moderate correlation (r=0.525; p<0.01) was found in the knee. CONCLUSION: Based on the results of this study, we conclude that FMS has only a moderate relationship with active ROM for the knee test. Therefore, the functional screening is sensitive to hamstring muscle length, in relation to the active joint mobility considered. Keyword: Functional movement screen, range of movement, joint mobility
