Previous studies have shown cyclic changes in the activation levels and performance of different tasks throughout the menstrual cycle. The aim of this study was to examine if changes in the reaction time to both light and sound stimuli may be associated with basal body temperature changes and subjective assessments of General and High Activation during the different phases of a menstrual cycle ...

Background: The menstrual cycle is an integral part of a major portion of a woman’s life, associated with significant changes in multiple neurohumoral homeostatic mechanisms. In the present study, autonomic modulation in different phases of menstrual cycle in young adult and older adult women’s was assessed. Methods: About 90 subjects were recruited and were divided between 2 groups and their H...

Objective: To examine the effects of menstrual cycle on exercise-induced inflammation, we investigated exercise-induced changes in circulating cytokines and leukocyte responses during different phases of the menstrual cycle. Methods: Ten healthy sedentary females (20.5 ± 0.7 years) performed 60 min of cycling at 75% of their individual anaerobic threshold (AT) during the three different phases ...

Menstruation is a phenomenon unique to females and nearly universal experience in women's lives and is poorly understood. It is characterized by co-ordinated sequence of hormonal changes but the changes that occur in the distribution of hematological parameters and biochemical parameters have not been clearly established. The present study was undertaken with the following aim: i) To compare he...

s Background:Sexual dimorphism in coronary artery disease (CAD) mortality is attributed to the cardioprotective effects of estrogen.This is reinforced by the observation that incidence of myocardial infarction is higher in menstrual phase, corresponding with low estrogen levels, in people who are predisposed to CAD due to the presence of modifiable risk factors. Cyclical variability of estrogen...

objectives in this study the association of phenotypes and activity of butyrylcholinesterase (buche) with serum level of lipid-lipoprotein and apolipoproteins during various phases of menstrual-cycle was determined. methods the study population consisted of 22 healthy women aged 19–25 years with regular menstrual cycles, 26–30 days in length. the serum levels of lipids, apolipoproteins, and buc...

Various studies have reported the effect of different phases of normal menstrual cycle on the autonomic control over the cardiac activity using heart rate variability (HRV) analysis. However, information on cardiac autonomic activity in young females suffering from primary dysmenorrhea (PD) is scant. Hence, the aim of the present study was to assess the HRV and blood pressure (BP) in different ...

The aim of this experiment was to compare the cardiac autonomic activity and BMI in the different phases of menstrual cycle using Heart rate variability. Heart rate variability (HRV) in women has been related independently to endogenous sex hormones, hormone replacement therapy, menopause, menstrual cycle, body mass index (BMI), and physical conditioning .It has become a popular non invasive to...

Hormonal changes associated with menstrual cycle are known to affect different organ systems. Fluctuation in the ovarian hormones during different phases of menstrual cycle – menstrual, follicular, and luteal phases may affect the cardiovascular and respiratory function in young healthy women. Seventy-five healthy Indian female subjects, 18-25 years old, from in and around Mangalore district we...

The whole gut transit rate has been measured in the follicular and luteal phases of the menstrual cycle in 18 healthy women in whom ovulation was confirmed biochemically. Mean transit time in the follicular phase (45.2 (2.7) h, mean (SEM) was not significantly different from the luteal phase (51.3 (4.1], p = 0.12. Stool weight was also not significantly different in the two phases (132 (7) v 12...
