Conditioning exercise decreased premenstrual symptoms during 3 months of a prospective controlled training study. Eight women with normal ovulatory menstrual cycles began a running exercise training programme while completing intensity-graded questionnaires concerning molimina. Six sedentary control women followed the same protocol for 3 months but did not exercise. Oral basal temperatures evaluated by mean temperature analysis were obtained for all cycles. Exercise distance and time, average exercise heart rate, basal and maximal heart rate and body weights were recorded prospectively and evaluated during the control (0) and 3rd month of the study. Mid-luteal phase progesterone and estrogen levels were sampled during the analyzed cycles for the exercise group. Molimina did not change over 3 months time in the control group. The exercise group, after increasing distance run to 51.0 +/- 18.1 km/cycle at 3 months, showed decreases in overall molimina (scores on a 9-point scale) 6.5 +/- 1.8 to 3.5 +/- 0.9, p less than 0.01). Breast symptoms decreased from 8.3 +/- 0.7, p less than 0.005. Fluid symptoms also decreased from 7.3 +/- 1.8 to 5.5 +/- 0.9, p less than 0.025. Menstrual cycle intervals, luteal lengths, body weights and mid-luteal estrogen and progesterone levels were normal and unchanged. Moderate exercise training without major weight, hormonal or menstrual cycle alteration significantly decreased premenstrual symptoms.

Exercise is commonly listed as a remedy for the premenstrual syndrome (PMS), although no study has proven that it is an effective therapy. Numerous reports have suggested that exercise is associated with improved mood and symptoms. In those reports, however, the diagnosis of PMS was not clearly documented, nor was the exercise carefully controlled. Preliminary evidence suggests that exercise training in ovulatory, sedentary women and intensified training in women athletes decrease mild premenstrual symptoms. Although conditioning exercise is associated with short luteal phase and anovulatory cycles, decreases in mild premenstrual symptoms occur prior to menstrual cycle changes. Controlled studies of PMS and exercise training may not only document an effective, nonpharmacologic therapy for PMS but also clarify the hormonal etiology of this complex biobehavioral phenomenon.
Six months of exercise training was associated with decreased premenstrual symptoms in two groups of women. There was no change in symptoms in nontraining women. Eight sedentary (ST) women increased running from 0 to 76 +/- 26 km/cycle (mean +/- standard deviation) over 6 months and seven runners (MT) trained for a marathon (42.2 km). Six normally active, nontraining (C-NT) women kept their activity constant. Each subject completed monthly intensity-graded questionnaires or kept daily symptoms diaries concerning premenstrual symptoms. All monitored basal body temperature, weight, and exercise. Gonadal steroids were measured in ST women. For ST subjects, breast (P = 0.005), fluid (P = 0.01), and personal stress (P = 0.025) decreased. MT women experienced decreased fluid (P = 0.034) and depression (P = 0.014). Anxiety tended to decrease (P = 0.087). ST and MT subjects experienced decreases in premenstrual symptoms without documented hormonal, menstrual cycle, or weight changes. These symptom changes appear to be the earliest evidence of the effects of conditioning exercise on the reproductive system.

Physical activity is known to improve physical and psychological outcomes in pregnant women. While aerobic exercise is typically emphasized in physical activity guidelines for pregnant women, emerging research suggests that strength training may offer unique benefits beyond those provided by aerobic exercise alone. This systematic review aimed to systematically explore the effects and characteristics of strength training interventions on the health‐related quality of life of pregnant women, with the goal of informing more comprehensive and specific exercise guidelines. Material and A systematic literature search was conducted across PubMed, Web of Science, and EBSCO Host databases without time restrictions, following PRISMA guidelines (Prospero Id: CRD42024511477). Nine randomized controlled trials met the inclusion criteria, involving a total of 1581 participants. The studies reviewed demonstrated that strength training during pregnancy can mitigate excessive weight gain, alleviate low back and sciatic pain, enhance mood, and improve various aspects of health‐related quality of life. These aspects include physical activity levels, muscular strength, flexibility, sleep quality, energy expenditure, and psychological well‐being. Despite these promising findings, this review highlights the need for standardized methodologies and detailed reporting in future research. Incorporating strength training into general exercise recommendations for pregnant women has the potential to optimize maternal health outcomes such as muscle strength, weight gain, physical activity levels, low back pain, pelvic pain, fatigue, anxiety, energy levels, vitality, sleep duration, and health status.

To investigate the efficacy and safety of open-label placebos (OLP) in premenstrual syndrome (PMS).
Randomised controlled trial.
Switzerland, 2018-2020. 150 women (18-45 years of age) with PMS or premenstrual dysphoric disorder. Random assignment (1:1:1) to treatment as usual (TAU), OLP without treatment rationale (OLP-), or OLP with treatment rationale (OLP+). OLP consisted of two placebo pills per day for 6 weeks. Primary outcomes were PMS symptom intensity and interference between groups across three menstrual cycles (MC1-MC3); adverse events (ie, safety) were measured at weeks 3 and 6 after the start of the intervention. Secondary outcomes were psychological and somatic subscales of PMS symptom intensity, and adherence. From 2 August 2018 to 3 December 2020,
