Análise da assimetria bilateral de força por testes de saltos verticais: salto com contramovimento e salto agachado

Abstract

The analysis of bilateral strength asymmetry in athletes is important for injury prevention and performance improvement. Laboratory methodologies are not adequate because they differ a lot from sports movements, which is why jumping with countermovement is an adequate test to verify asymmetries. The squat jump test has a movement pattern similar to sports practice techniques. Therefore, this study aims to verify the agreement of the diagnosis of strength asymmetries measured through the jump tests with countermovement and squatting jump in soccer athletes. 29 professional soccer players participated in this study. From the tests of jumping with countermovement and squatting jump, the impulse for each lower limb served to determine the bilateral strength asymmetry. The correspondences of these diagnoses were investigated by the McNemar test. The analysis showed that the tests do not have significantly concordant diagnoses for the determination of ABF.
