[EMG characteristics of women in respect with phase of the menstrual cycle, season and type of vegetative regulation].

Here we report on the electromyographic (EMG) characteristics of young females (n = 23, 19.9 +/- 1.4 years) under varied environmental and physical conditions: 4 phases of menstrual cycle phase (early and late follicular, ovulation, and luteal), spring and autumn seasons, and type of the vegetative nervous system (VNS) regulation based on the linear and novel non-linear parameters of interference EMG (iEMG) in m.

[The thermoregulating function of the motor units in the muscles of the pelvic floor of the cat].

An interaction between supraspinal respiratory input and the thermoafferent one in the pelvic floor muscles' motor units depended on the body temperature. The data obtained suggest that the thermoregulatory activity in the pelvic floor muscles affect the so called expulsive acts (defecation etc.) followed by the muscle relaxation.

[The characteristics of the impulse activity of the motor units of the muscles in the pelvic floor in the cat].

The investigation have been designed to elucidate the background and thermoregulatory activity (TA) of the motor units (MUs) of pelvic floor muscles (m. spincter ani externus, m. levator ani) and hind limb muscle (m.
