During the period encompassing 10 sessions of the quadriceps femoris muscle electromyostimulation in athletes (n=72), the following cardiac parameters changed signifi cantly: QT-interval dispersion and the incidence of supraventricular and ventricular extrasystoles decreased, while the circadian index increased. No signifi cant changes in the temporal- and frequency-domain parameters of the heart rate were observed, although there was a clear trend to normalization of the disturbed sympathovagal balance in the athletes. © 2011 Springer Science+Business Media, Inc.

We describe cross effect of enhancement of muscular power and electrical activity during electrical stimulation. Due to the use of electrostimulation method with biological feedback and effort visualization for the examinee, its expression on non-stimulated leg by some indices approached that on the stimulated leg. © 2010 Springer Science+Business Media, Inc.

We studied the effect of a course of electrical stimulation of the quadriceps femoris muscle with submaximal contraction under biofeedback conditions on functional capabilities of the organism. In addition to the known effects, electrostimulation course modulated the content of intra- and extracellular fluid and increases MDA content and creatine phosphokinase activity, which can be a manifestation of overtreatment. Impairment of body static balance after the course was revealed. Thus, monitoring of the effects of electrostimulation is required during the course. © 2010 Springer Science+Business Media, Inc.
