Abstract: Here we report on autonomic status using the statistic and spectral parameters of the heart rate variability (HRV) of 23 young females (19.9±1.4 years) under varied environmental and physical conditions: 4 phases of the menstrual cycle (MC, early and late follicular, ovulation and luteal), spring and autumn seasons. Being taken separately, either factor of the menstrual cycle phase or season imposed only minor effects on the HRV, but most of the variables of the HRV were significantly different from other phases in the ovulation phase in the spring season in the form of the parasympathetic nervous system decreased activity with a reciprocal increase of the hormone-hypothalamic level of the cardiovascular regulation, what was seen as the increased VLF (very low frequencies) and decreased HF (high frequencies) and the decreased portion of successive pairs of intervals (pNN50).
