Analysis of knee angulation in bodybuilders

The dynamic valgus is a biomechanical change in the excessive postural pattern of the knee joint, this change can be caused by excessive rotations of the hip and knee joint, and may be linked to a paresis of the muscles of the pelvis and thigh. The knee joint will move medially in relation to the foot due to the weakness of the posterolateral hip stabilizers, the knee makes an excessive abduction and hyperpronation of the foot due to the foot fixed on the ground. The objective of this research is to analyze the dynamic valgus of the knee in individuals who practice weight training. This is a descriptive, analytical study with a cross-sectional design and quantitative approach. Participants answered a sociodemographic questionnaire and about bodybuilding. The test was done by video, the participants were positioned in orthostasis, on top of the step, where they were instructed to descend from a step and immediately after landing perform a maximum vertical jump. The results showed that 12.5% (n = 1) presented this posture and 87.5 did not present the valgus. From the results of the present study, it is evident that bodybuilding practitioners do not necessarily have dynamic valgus.
