[Modification of reactivity by rhythmic neuromuscular stimulation].
The rhythmical neuromuscular stimulation (RNS) by Nasarov is a new method for optimizing performance. By transferring mechanical vibration to the tendomuscular system better coordination of peripheral and central nervous system could be achieved. A study with twelve healthy students of physical education dealt with the question of the effects of RNS on drop jumps. After 12 minutes application of RNS the performance drastically decreased. Jumping height lowered and ground contact time increased. Recordings of EMG revealed corresponding alterations in muscle activity, such occurring in overload situations. Plastic deformation of tendon collagen and neuromuscular adaptation as stiffness-reduction of gamma-modulation is discussed.
