Abstract

Futsal has extensive reports of lower limb injuries, with the knee joint being one of the most affected. Drop Vertical Jump (DVJ) and Sidestep Cutting (SID) are tests that analyze knee changes to prevent injuries in professional futsal athletes. However, in the literature, the number of studies correlating knee tests with the Isokinetic Dynamometer (ISO) is scarce. Thus, the objective of the study is to compare the biomechanical variables of lower limbs (MI) in DJV and SID and to correlate with ISO in futsal athletes. Participants were 15 male athletes, aged 18 to 35 years, who performed the VJD (with a 40 cm high crate) the SID (change of direction with ball) and the ISO muscle test. Two Bertec force platforms were located at the time of DVJ landing and the change of direction in the SID. ISO followed a protocol of three series of 5, 10 and 20 repetitions, at speeds of 60 °. s-1, 180 °. s -1 and 300 °. s-¹. Twenty-one retroreflective markers were placed in the MI, in addition to 4 electromyography (EMG) sensors. The analyzes will be processed in MatLab software to obtain angular velocities of the knee, angles of rotation, peak ground reaction force across the platforms and the signs of muscular activation captured by the EMG. The peak torque and symmetry index of the extensor and flexor musculature of the MI (I / Q ratio) will be obtained through the Biodex software. In case of acceptance of the FAPESP bag, there is interest of the BEPE bag. Pearson correlation and paired t-test will be performed, assuming significance of p <0.05.
