Integrated Assessment of the Functional State of Healthy Students in Dependence on the Phase and the Duration of the Menstrual Cycle

Abstract

Relevance: one of the causes of menstrual disorders are functional disorders associated with a violation of the central regulatory level.The aim: integratively assess the functional state of healthy girls, depending on the phase and duration of the menstrual cycle. Materials and methods: observations were performed on 65 practically healthy girls 18-19 years old with regular menstrual cycles. They conducted questionnaires, gynecological examinations, tests on functional diagnostics tests, ultrasound scanning of pelvic organs. To determine the phases of the menstrual cycle used the method of Ogin-Knaus, the onset of ovulation used a test for luteinizing hormone (strip tests of the brand Eviplan). The concentration in the blood of estradiol and progesterone was selectively determined. All subjects underwent a cardio-respiratory synchronism test. The parameters of the serous-respiratory synchronism determined the index of the regulatory-adaptive status, and according to it the regulatory-adaptive capabilities (functional state) were evaluated. Statistical analysis of the results of the study was carried out using the following programs: «STATISTICA 10» of «Stat Soft, Inc.». After establishing the normal distribution of the variant, significant differences were used in comparing the mean values in paired comparisons, taking the t-test of Student for p < 0.05. Results: in 35 people the duration of the menstrual cycle was 21-27 days. In the follicular phase, the regulatory-adaptive status index was 183.0 ± 0.4, which indicated a high regulatory adaptive capacity. In the luteal phase, respectively, 60.1 ± 0.3, - good regulatory adaptive capacity. In 30 watchers, the cycle was 28 to 32 days. In the follicular phase, the regulatory-adaptive status index was 156.5 ± 0.6. Regulatory adaptive capabilities were good. In the luteal phase, respectively, 52.4 ± 0.5 are good regulatory adaptive capacities. The conclusion: Regulatory adaptive opportunities for female students are greater in the follicular phase of the menstrual cycle than in the luteal cycle. Regulatory adaptive capacity is greater for a cycle of 21 to 27 days than for a cycle of 28 to 32 days.
