Efeitos da compressão sobre a cinemática de saltos em condição de fadiga muscular

Abstract

Jumping tasks predispose to a greater risk of injury to the anterior cruciate ligament of the knee during landing maneuvers, due to variations in the flexion and valgus angles of the knee. Wearing compressive clothing can minimize these changes during jump-landing maneuvers. However, its effects have not been tested in a fatigued condition, where joint movement control is impaired. In this study, we determined whether compression on the lower limbs, through the use of compressive shorts, affects the knee kinematics in landing jumps in fatigued condition. Physically active women (n=11) with 22.8 (3.1) years of age, height 1.65 (3.1) m, body mass 61.9 (7) kg, performing countermovement jumping tasks were evaluated. and fall with and without the use of compressive shorts, before and after a fatigue protocol. kinematic data were obtained with 3D kinemetry. For each jump, the shorts and fatigue conditions were compared by analysis of variance. Compressive shorts did not reduce knee range of motion in the fatigued condition of jumping tasks. Therefore, the use of compressive shorts was not effective in reducing knee range of motion in the sagittal and frontal planes in a fatigued condition.
