Abstract
For the proper functioning of the lower limb, it is necessary that each of the anatomical structures function in the correct way. The reduced ability to generate the torque of the lower limb in the hip joint can lead to abnormal functioning of the lower limb. The aim of the study is evaluation of muscle activity of the lower limb during isometric rotation based on measurements using a dynamometric and dynamographic platform.
For the purposes of testing the values of torque, people stood on one limb on the dynamometric platform. The examination of the pressure distribution of the feet on the ground was carried out in the same position as during the test on the dynamometric platform. One measurement lasted 10 s. Simulations based on collected data were made in AnyBody system.
The results of the tests were values of hip torque, muscles activity, muscles forces during isometric lower limb rotation.
The results of the above studies show the influence of force resulting from the rotation of the lower limb on muscle strength generated by this limb. There were also differences in muscle activation during isometric rotation with the lower limb in the external and internal direction. An exercise that is isometric rotation activates many muscle groups of the lower limb. This exercise can improve the functioning of the lower limb as a separate exercise and as an element of strength exercises such as squat.
