Большинство обследуемых девушек в обе фазы овариально-менструального цикла показало умеренный уровень ситуативной тревожности и благоприятное состояние, что позволяет им продуктивно работать и адекватно реагировать в различных ситуациях. Анализ когнитивной сферы не выявил значимых различий в обе фазы цикла. Вариабельность сердечного цикла при когнитивной нагрузке в сравнении с состоянием покоя в фолликулярную фазу свидетельствуют о централизации в управлении сердечным ритмом. В лютеиновую фазу происходило смещение вегетативного баланса в сторону преобладания симпатического отдела без усиления влияний церебральных структур регуляции The majority of the surveyed girls in both phases of the ovarian-menstrual cycle showed a moderate level of situational anxiety and a favorable state, which allows them to work productively and respond adequately in various situations. Analysis of the cognitive sphere revealed no significant differences in both phases of the cycle. The variability of the cardiac cycle during cognitive load versus resting in the follicular phase is indicative of centralization in heart rate control. In the luteal phase, the vegetative balance shifted towards the predominance of the sympathetic section without increasing the influence of cerebral regulation structures

1. The haemodynamic effects of hormonal changes during the menstrual cycle were examined in 11 normotensive women (age 20–46 years). The subjects were studied on days 2–8 (follicular phase) and days 18–26 (luteal phase) in a randomized order. A standardized mental stress test and a 24 h recording of ambulatory blood pressure and heart rate were performed. 2. Pre-stress resting levels of heart rate and blood pressure were similar during the two phases of the menstrual cycle. 3. During mental stress, the heart rate response was significantly greater during the luteal phase than during the follicular phase (14.7 versus 9.7 beats/min; P < 0.05). 4. Blood pressure, plasma catecholamine concentrations and subjective stress experience increased significantly in response to stress, without any significant differences between the two phases. 5. During 24 h ambulatory monitoring, higher levels of systolic blood pressure and heart rate were observed in the luteal phase than in the follicular phase (P < 0.005 and P < 0.0001, respectively). 6. These data indicate that cyclic variations in female sex hormones not only affect systolic blood pressure and heart rate, but also alter the haemodynamic responses to psychosocial stress.

Background: The hormonal fluctuations that occur during normal menstrual cycle has profound influence on autonomic functions. This influence on autonomic nervous system may affect cardiovagal control. The aim of the study is to find out the variation of Parasympathetic function tests during different phases of menstrual cycle in young healthy females.Methods: The present study was carried out on 50 healthy female subjects with normal menstrual cycles between the ages of 18 to 25 years. Various non-invasive parasympathetic function tests during different phases of menstrual cycle were performed that include Resting heart rate (RHR), Heart rate variation during deep breathing (E:I Ratio), Heart rate response to standing (30:15 Ratio), Heart rate response to Valsalva maneuver (Valsalva Ratio). The results were analysed using ANOVA and student’s paired-t tests.Results: During the menstrual cycle, we found varied heart rate response with higher values towards the luteal phase, when compared to the follicular phase and the menstrual phase. There was a statistically significant difference in the heart rate parameters like resting heart rate, 30:15 ratio, valsalva ratio and E:I ratio during the three phases of menstrual cycle.Conclusions: The study concludes that there was statistically significant heart rate variability during three phases of the menstrual cycle, as observed by the increased sympathetic discharge in the luteal phase compared to the increased parasympathetic discharge in the follicular phase. The results of our study have emphasized the complexity of the relationship between ovarian steroids and various hemodynamic regulatory systems.

This study was designed to assess the changes in nonlinear properties of heart rate (HR) variability (HRV) during the menstrual cycle by means of complexity measures, including sample entropy (SampEn) and correlation dimension (CD), and explore probable physiological interpretations for them. In 16 healthy women (mean age: 23.8 ± 2.7 yr), complexity measures along with the spectral components of HRV (sympathovagal markers) were analyzed over 1,500 R-R intervals recorded during both the follicular phase ( day 11.9 ± 1.4) and the luteal phase ( day 22.0 ± 1.4) of each woman's menstrual cycle. Simultaneously, serum ovarian hormone (estradiol-17 and progesterone) and thyroid-related hormone [free triiodothyronine, free thyroxine (T4), and thyroid-stimulating hormone] concentrations were measured. With regard to HRV measures, SampEn, CD, and high-frequency (HF) components decreased from the follicular phase to the luteal phase, whereas normalized low-frequency (LF) components and the LF-to-HF ratio as well as resting HR increased. In regard to hormone levels, whereas progesterone was increased, the other hormone concentrations were unchanged. Furthermore, across the menstrual cycle, both SampEn and CD were well correlated with the spectral indexes and free T4 concentrations, and SampEn also showed significant correlations with the ratio of estradiol-17 to progesterone concentrations. These results suggest that the nonlinear properties in HRV are altered during the regular menstrual cycle and that the autonomic nervous system, ovarian hormone balance, and free T4 may be involved in nonlinear HR control in healthy women. All of these factors may enrich the physiological meanings of complexity measures.

Background Alteration in physical work capacity of females during different phases of menstrual cycle has been reported in different populations. Pertinent data is unavailable in Eastern Indian population. Objectives The present study was aimed to determine the endurance capacity and cardiorespiratory responses during different phases of menstrual cycle in young sedentary females of Eastern region of India. Methods Forty five unmarried young healthy sedentary females (21–25 years) were recruited in the present investigation. Duration of their menstrual cycle was 28–30 days. Cardiorespiratory parameters including the endurance capacity was determined by treadmill running with constant monitoring of heart rate by Polar heart rate monitor. Results The pre-exercise heart rate was significantly higher (P<0.02) in the luteal phase. The peak heart rate was significantly lower (P<0.02) in the flow phase than the follicular and luteal phases. VO2max, O2 pulse, maximum pulmonary ventilation and endurance capacity were significantly lower in the follicular phase. However, the endurance capacity was significantly lower in the flow phase. Pre-exercise systolic and diastolic blood pressure did not exhibit any significant variation in different phases of menstrual cycle. Conclusion Therefore, from the present observations it may be concluded that pre-exercise heart rate and respiratory rate are significantly higher in the luteal phase whereas VO2max, O2 pulse, maximum pulmonary ventilation, endurance capacity and peak heart rate were significantly lower in the follicular phase.

Introduction: Menstrual cycle or menstruation involved discharge of sanguinous fluid and a sloughing of uterine wall. In women menstruation occurs at regular intervals on an average of 28 days, although most women gave a history of regular intervals of 28 to 30 days. About 10% -15% of women showed cycle at the precise 28 ± 2 days intervals when menstrual calendar was utilized. Normally in young women in different phases of ovarian cycles the plasma levels of estrogen vary. Ovulation occurs in the first 12-13th day of menstrual cycle, which is termed estrogen surge and second occurs in mid-luteal phase. During mid cycle or follicular phase of menstrual cycle the plasma concentration of progesterone is very low about 0.9 ng/mL. its level starts rising owing to secretion from the granulose cells. During luteal phase progesterone level reaches its peak value of 18 ng/mL and its level fall to a minimum value toward the end of the cycle. Estrogen affects local and systemic vasodilation. The menstrual cycle envelops two fundamental stages, the follicular stage (FP) and the luteal stage (LP). The follicular stage can part advance into two substages; the early FP, which is characterised with moo concentrations of both the key hormones estrogen and progesterone; and the mid FP where estrogen is tall autonomously from progesterone. The LP is epitomized by tall concentration of both estrogen and progesterone. These two fundamental stages are isolated by a soak surge in luteinizing hormone activating ovulation. These recurrent changes are said to be frequency unsurprising while long time. Aim: The main aim of this study is to evaluate the Cardiorespiratory functions changes during different Phases of Menstrual Cycle.   Material and methods: In this study, 20 with normal weight, 20 with obese and 20 with overage were included and taken them as a sample size. In this study all the young women those were recruited as a sample size are unmarried, undergraduate female student with the between the age group of 18-22years, having regular 28+6 days menstrual cycle for at least last 6months prior to this study. For the collection of data all the participants were instructed to attend the physiology lab department during each of three different phases. Day-2 during menstrual phase, Day-7, during follicular phase and Day-22 during luteal phase and the following parameters were recorded as Anthropometric measurements, measuring of pulse rate and blood pressure and cardiac efficiency test. Result: In general, work out proficiency changed essentially amid the distinctive stages of the menstrual cycle with the most elevated amid luteal stage and least amid menstrualo stage. There was no critical contrast in impact test amid menstrual stage, follicular stage and luteal stage of menstrual cycle among three bunches of people. Conclusion: We have watched noteworthy increment in cardiac and respiratory proficiency within the luteal stage of the menstrual cycle in ordinary weight people. Lower wellness levels were watched in overweight and stout females. In this manner hone of customary work out and admissions of solid slim down which offer assistance in lessening the weight and in turn the BMI will offer assistance in improving the physical wellness of the people. Keywords: Cardiorespiratory, Menstrual cycle, expiratory blast test
