The relationship between functional performance and maximum dorsiflexion range of motion and ankle angle during the test execution in futsal players

Abstract

Introduction: High prevalence of lower limb injuries in futsal players is reported, and the ankle joint is the most affected region. Moreover, restricted dorsiflexion range of motion (DFROM) may alter performance on the dynamic task. There are no studies in
futsal players that assess the relationship the DFROM and the physical performance. Objective: To investigate the relationship between DFROM and the anterior component of the Y-Balance Test (YBT). Secondarily, to investigate the potential assessment method and leg dominance influences. Methods: This cross-sectional study included sixty-one asymptomatic male futsal players with a total of 122 lower limbs. DFROM was measured by the Weight-bearing Lunge Test (WBLT) and during the Y-balance test (YBT). Visual kinematic data of the ankle were obtained during both tests. Pearson correlation coefficient verified the correlation between the DFROM and the reach of the YBT. Results: There were low to moderate significant correlations between DFROM and the anterior component YBT for both method [right ankle measured by WBLT (r=0.326) and YBT (r=0.377); left ankle measured by WBLT (r=0.443) and YBT (r=0.575)]. Mild to low correlations were found between the DFROM and the other components of the YBT. There was no significant difference related to the assessment method and leg dominance. Conclusion: In Futsal players, DFROM is directly correlated with the previous YBT component. The relationship between DFROM and YBT is independent of the assessment method and leg dominance.
