BACKGROUND Sex hormones are known to regulate some responses during exercise. Evaluation of the differences in exercise response with regard to menstrual cycle will help understand the menstrual cycle phase specific adaptations to exercise and athletic performance. METHODS We investigated the effects of menstrual cycle phase and carbohydrate (CHO) ingestion on immune response during endurance...

Body temperature and sleep change in association with increased progesterone in the luteal phase of the menstrual cycle in young women. The mechanism by which progesterone raises body temperature is not known but may involve prostaglandins, inducing a thermoregulatory adjustment similar to that of fever. Prostaglandins also are involved in sleep regulation and potentially could mediate changes ...

conclusions the most comfortable postoperative women were those in luteal phase without history of pms group. results patients with pms presented higher pain sensation and analgesia request (p = 0.003). patients in luteal phase showed less pain and analgesia request in two out of five studied outcomes (p = 0.075). patients and methods a total of 140 women in in postoperative period were assigne...

INTRODUCTION Hormonal fluctuations may influence fibrin structure. During the menstrual cycle, plasma fibrinogen levels change, mainly due to the variations of estrogen. Throughout the menstrual cycle estrogen levels peak twice, first during the mid-follicular phase and then a lower second peak during the luteal phase. MATERIALS AND METHODS In order to investigate the possible changes in the ...

OBJECTIVE To investigate the diurnal rhythm of estrogens in normally cyclic women during reproductive life. DESIGN Multiple saliva sampling in normally cyclic healthy women during reproductive life at different phases of their menstrual cycles was carried out. METHODS Salivary estradiol was measured by radioimmunoassay in samples collected every 2 h for 24 h from 15 normally cyclic healthy ...

We investigated the effects of time-pressure stress on Raven’s Standard Progressive Matrices performance in 64 lowand 64 high-trait anxious female subjects, tested either during premenstruation or menstruation. Based on previously reported associations between arousal/stress and intelligence test performance, we predicted that menstrual cycle variation would interact with stress-induced arousal...

Human thioredoxin, a cellular disulphide reducing protein, is known to be secreted by some types of cells and to display unique extracellular activities including modulation of cytokine actions and protection of the cell against damage from oxidative stress. This study has been undertaken to investigate the pattern of expression and tissue distribution of thioredoxin in human endometrium during...

ABCB1, also known as MDR1/P-glycoprotein, can transport cortisol and aldosterone. We examined the effects of ABCB1 polymorphisms on serum levels of cortisol and aldosterone among different phases of the normal menstrual cycle in 51 non-pregnant healthy Japanese female volunteers (22 +/- 1 years old). The menstrual cycle was divided into three phases: premenstrual phase (14 days preceding the on...

conclusions the stress due to psychosomatic changes in the menstrual cycle is associated with premenstrual syndrome. measures of s-iga, rather than cortisol or subjective responses to stress, may be most closely associated with pms. background several studies have demonstrated the associations between premenstrual syndrome and perceived stress, and no studies quantifying stress based on biochem...

Various studies have shown fluctuations in task performance during the menstrual cycle. The aim of this study was to see the effects of the menstrual cycle on performing fine motor and spatial tasks of different level of complexity in twenty students aged 18 to 21 years, with regular menstrual cycle (28 to 30 days). The students performed O'Connor Finger Dexterity Test and mental rotation test ...
