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.

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.

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.

The effects of 6-h marathon ultra-race (long aerobic work below the lactate threshold level) on the levels of IL-6, leukemia inhibiting factor (LIF), and stem cell growth factor (SCF) were studied. The athletes participating in the study had different endurance levels evaluated by the distance covered over 6 h. The level of IL-6 sharply increased after exercise. The degree of IL-6 increase correlated with the length of the distance covered (r=0.83, p=0.042). The concentration of LIF after exercise inversely correlated with the distance covered (r=-0.75), but this correlation was statistically insignificant. The IL-6/LIF proportion exhibited the highest correlation with the result in the marathon ultra-race. This parameter most fully characterized athlete endurance (r=0.92, p=0.009). Hence, the relationship of LIF with physical endurance was demonstrated. Involvement of LIF in antibody production processes can be responsible for it.

We developed a method of rapid assay for biochemical properties of the saliva based on attenuated total reflection infrared spectroscopy. This method allows evaluating saliva composition within 5 min without sample preparation; 10 microl sample is enough for the analysis. The concentration of total protein, glucose, secretory immunoglobulin A, urea, amylase, cortisol, inorganic phosphate in the saliva can also be measured. Precision and reproducibility of the evaluated parameters are comparable to those obtained by routine clinical analysis.
