Study aim: To determine the relationships between muscle torques of lower leg rotators and rotation angle, and angular position at the knee joint.Material and methods: A group of 171 untrained male subjects aged 19 - 25 years were studied. A specially designed measuring set was used. Muscle torques were determined at -30, 0 and 45° of lower leg rotation, angular positions at the knee joint being 30 or 90°.Results: Rotation angle and angular position at the knee joint, as well as the declared laterality, significantly affected muscle torques of lower leg rotators. Highest muscle torques amounted to 55.2 ± 5.6 Nm (lower leg pronation) and 42.6 ± 7.4 Nm (lower leg supination).Conclusions: The results may contribute to a deeper evaluation of human locomotor apparatus and to reduce the destructive forces acting on the knee joint in athletes and to improve monitoring the functions of reconstructed knee joint in rehabilitees.
