KNEE JOINT TORQUE MEASUREMENTS BEFORE, DURING AND AFTER TRAINING WITH ELECTRICAL STIMULATION
Keywords: electrical stimulation, knee joint dynamometer, knee joint torque
AbstractThe aim of this study was to investigate the influence of an eight-week Electrical Stimulation (ES) training program on the knee joint torque of the knee joint extensor muscles of six test persons (three trained hobby sportsmen ‘T ES’ and three untrained test persons ‘UT ES’). ES sessions were carried out with simultaneous maximum voluntary isometric contraction five times weekly. A control group of six test persons (three ‘T NoES’ and three ‘UT NoES’) completed the same training program without ES. Every two weeks measurements on a dynamometer were done before, during and after training sessions. The averaged strength increase of the ‘UT ES’-group amounted to 9.5% and of the ‘T ES’-group to 5.7% at the knee joint flexion angle of 60°. The ‘UT NoES’-group achieved 9.1% at the same knee joint flexion angle.
