The Influence of Different Positions of the Ankle Joint on the Movement of the Knee

Abstract

[Purpose] We investigated the influence of different positions of the ankle joint on the movement of the knee. [Subjects and Method] Thirty healthy men, participated in the study. An isokinetic dynamometer Biodex was used to perform the movement of the knee. At a constant velocity of 60/sec, with 4 different ankle positions: dorsiflexion, extension, dorsiflexion to extension, extension to dorsiflexion. In each case the extension and flexion torque and torque/weight were measured. [Results] In flexion of the knee with ankle dorsiflexion, torque, torque/weight and power were significantly greater than in the other ankle positions. [Conclusion] In knee training it is more effective to use dorsiflexion of the ankle.
