[Biomechanical and physiological substantiation for application of functional muscle electrostimulation in performing rhythmic movements on bicycle ergometer].
Kinematic and electromyographic parameters in conduction of rhythmic movements on the bicycle ergometer were studied in a group of healthy subjects. It is shown that these movements are characterized by a stable biomechanical and innervation stereotype consisting of two interacting synergies: flexor and extensor. Force extensor synergy plays the key role which provides both triggering and maintenance of certain rhythm of rotation. Flexor synergy is primarily corrective. Basing on the data obtained, stimulated muscles are selected in basic phases of the cycle, algorithms of time and amplitude programs of muscle electrostimulation in conduction of bicycle ergometry are proposed.
