Introduction:Female sex hormones, estrogen and progesterone regulate various phases of the menstrual cycle. Hormonal changes tend to affect various parameters of physical fitness. Maximum oxygen uptake (VO2 max) is a measure of aerobic power. This study was planned to assess effect of different phases of menstrual cycle on cardiorespiratory parameters like pulse rate, respiratory rate and VO2 max.Methods:100 female medical students in the age group of 17-22 years were studied for three consecutive menstrual cycles. Weight, resting pulse rate, respiratory rate and VO2 max were measured during premenstrual phase (20th-25th day) and postmenstrual phase (5th to 10th day).Results:It was observed that there was a significant increase in body weight, pulse rate, and respiratory rate during premenstrual phase. There was a decrease in VO2 max during the premenstrual phase.Conclusion:This study indicates that there is decreased cardio-respiratory efficiency during premenstrual phase.

Introduction: The menstrual cycle involves a sequence of structural, functional, and hormonal changes in the reproductive system. This is linked and controlled by cyclical fluctuations in the levels of FSH, LH, estrogen, and progesterone. Because of these cyclical fluctuations, there might also be associated cyclical changes of magnesium and systemic arterial blood pressures during the menstrual cycle. Purpose: To assess the changes in serum magnesium level and systemic arterial blood pressures during the menstrual cycle in young reproductive women. Methodology: the sample population is 40 apparently healthy young reproductive-aged 18- 25years female students from the University of Medicine, Magway participated in this study. Systemic arterial blood pressures were measured by indirect method. The serum magnesium level was measured by spectrophotometry. These measurements were done in the early follicular phase (EF), the peri-ovulatory phase (PO), and the mid-luteal phase (ML) of the menstrual cycle. The serum magnesium levels were significantly (p <0.001) lower, and the systolic blood pressures were significantly higher (p <0.05) in the PO than the EF and the ML. In the EF, there was a significant negative correlation between serum magnesium level and diastolic blood pressure (r= -0.374, p <0.05) and mean arterial pressure (r = -0.354, p < 0.05) but no significant correlation with systolic blood pressure. In the PO, there was no significant correlation between serum magnesium level and systemic arterial blood pressures. In the ML, there was significant negative correlation between serum magnesium level and systolic blood pressure (r = -0.651, p <0.001), diastolic blood pressure (r = -0.607, p <0.001), and mean arterial pressure (r = -0.661, p <0.001). Conclusion: The study concludes that serum magnesium level has a negative effect on blood pressure changes and the blood pressure-lowering effect of magnesium. These changes are related to the fluctuation of estrogen levels during the menstrual cycle.
