This study investigated the impact of intensive endurance exercise on circulating androgenic steroid hormones in women. Fifteen normally menstruating athletic women participated. They completed intensive endurance exercise (treadmill running) until volitional fatigue in their follicular phase, with blood samples collected at pre-exercise, volitional fatigue, 90 min and 24 h into recovery.

Background: The rating of perceived exertion (RPE) is a readily available and practical tool widely used in exercise science to monitor exercise load, but a rigorous review of the effect of menstrual cycle (MC) phases on RPE within continuous aerobic exercise has not yet been completed.

Objective: This study investigated the effects of the MC phase on RPE during aerobic exercise.

Study Design: This was a systematic review and meta-analysis.

Introduction: Although there is potential for the menstrual cycle to impact psychophysiological responses to exercise, there has been a paucity of studies investigating this aspect, specifically in the context of high-intensity interval training (HIIT).

Purpose: This exploratory study aimed to examine the psychophysiological responses to HIIT over the menstrual cycle.

Methods: Twenty-three healthy and physically active young women were recruited.

Purpose: This study investigated the acute effect of anodal transcranial direct current stimulation (a-tDCS) over the left dorsolateral prefrontal cortex (DLPFC) on appetite, energy intake, food preferences, and mood states in the luteal and follicular phases of the menstrual cycle in women presenting premenstrual syndrome.

Methods: Sixteen women (26.5 ± 5.

Purpose: Most women during their lifetime experience a combination of premenstrual syndrome (PMS) symptoms (eg, menstrual cramps) before and often to the end of menstruation. However, the impact of these symptoms on sport routines (eg, performance, training absence) during phases around menstruation is still unclear. Therefore, we investigated the impact of PMS symptoms on sport routines among nonelite athletes over 3 phases related to menstruation.

This study investigated the psychophysiological responses during self-selected exercise intensity over the course of the menstrual cycle (MC). Seventeen healthy women with regular MCs completed three randomized treadmill bouts of 30 min of self-selected exercise intensity during menstruation, mid-follicular, and late luteal phases. Anxiety, menstrual distress (i.

Psychological responses such as affect, mood, motivation, anxiety are important considerations for exercise adherence. A large body of evidence indicates that exercise intensity is a controllable variable capable of increasing positive feelings. Investigations thus far, however, have not considered that the higher incidence of negative psychological responses in women could be due to physiological particularities of the menstrual cycle (MC).

The association of old age and chronic conditions, such as hypertension and obesity, can lead to larger decreases in the physical capacities of elderly, compared with their healthy counterparts. Physical exercise has been demonstrated to be efficient in postponing this phenomenon, mainly strength training. However, little is known about the effect of aerobic training on this condition.

Article Synopsis
  • - Studies indicate that higher activation in the left prefrontal cortex (PFC) before exercise is linked to more positive psychological outcomes, including better mood and reduced anxiety.
  • - A systematic review analyzed 1901 studies on this topic but narrowed it down to 8 relevant studies that met specific criteria involving EEG measurements and psychological assessments.
  • - Most of the studies (75%) supported the idea that greater left PFC activation correlates with positive states like energetic arousal and calmness, while some studies showed varying levels of bias in their methodologies.

Hypertension and obesity are prevalent diseases in elderly people, and their combination can cause deleterious effects on physiological system. Moderate intensity aerobic training (MIAT) seems to be a beneficial approach to control and treat these diseases separately. However, few studies have investigated the impact of MIAT on cardiovascular risk factors associated with these conditions (i.
