The purpose of this study was to analyse the relationship between several parameters neuromuscular performance with dynamic postural control using a Bayesian Network Classifiers (BN) based analysis.The y-balance test (measure control), isokinetic (concentric and eccentric) knee flexion extension strength, isometric hip abduction adduction lower extremity joint range motion (ROM) core stability were assessed in 44 elite male futsal players. A feature selection process carried out before building BN (using Tabu search algorithm) for each leg. models built used make belief updating processes individual concurrent contributions selected on control.The BNs generated features by algorithms correlation attribute evaluator chi squared reported highest evaluation criteria (area under receiver operating characteristic curve [AUC]) dominant (AUC = 0.899) non-dominant 0.879) legs, respectively.The demonstrated that achieved appears be widely influenced ankle dorsiflexion ROM measures sagittal plane, as well static but mainly frontal plane. Therefore, training interventions aimed at improving or maintaining players should include, among other things, exercises produce scores equal higher than 127° flexion, 132.5° 34° 30.5° flexed extended, respectively. Likewise, these also include maintain improve both (medial-lateral plane) so can achieve medial radial error values 6.69 8.79 mm,
