Abstract

Aim: to study correlations between sex hormones and psychophysiological indicators at various impacts on the body, including muscle strain. Materials and Methods. The study involved 50 volunteers – 18-23-year-old female students. Two series of observation were conducted: 1 – at relative muscle rest, 2 – immediately after exercise at cycle ergometer (time – 20 min, workload – 24,500 kg/m). Pedaling rate was 60 rotations per minute. Using softwarehardware complex “Varikard 2.51” we studied the baseline tone of autonomous nervous system. Sensomotor reaction rate was measured using PS-Psikhotest complex. Results. It was found that if parasympathetic or sympathetic tone of of the nervous system prevailed the concentrations of sex hormones at rest and after exercise. The significant increase of the concentration of sex hormones was typical of the vagotonics, and the decreased rate of simple sensomotor reactions was observed in sympathotonics. The significant correlations were revealed between the concentrations of follicle-stimulating hormone, luteinizing hormone, estradiol and cortisol – and psychophysiological indicators. Conclusion. The analysis of hormones in people with different individually typological features of balance of sympathetic and parasympathetic parts of the vegetative nervous system and psychophysiological indicators at rest and after exercise suggests that the level of hormones influences the rate of visuomotor and auditory-motor reactions (both simple and, especially, complex) and error rate.
