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.

This systematic review and meta-analysis examined the relationship between menstrual cycle phases and the incidence of muscle injuries in female team sport athletes, following PRISMA 2020 and PERSiST guidelines. A comprehensive search was conducted in PubMed, Scopus, and SPORTDiscus from inception to mid-January 2024. Studies were included if they examined female team sport athletes of reproductive age with regular menstrual cycles and compared the occurrence of muscle injuries across at least two menstrual phases. Studies involving hormonal contraceptive use, medications affecting the menstrual cycle or musculoskeletal system, or menstrual dysfunction were excluded. Three studies met the inclusion criteria, involving 318 participants. Meta-analysis yielded a pooled Risk Ratio of 1.18 (95% CI: 0.75 to 1.86, p = 0.46) for injury risk between the luteal and follicular phases, suggesting no statistically significant association. However, the certainty of the cumulative evidence was rated as very low due to methodological limitations, including inconsistent phase classifications and reliance on imprecise methods for identifying menstrual phases. Consequently, no practical or clinical recommendations can be made at this time. Future research employing standardised, physiologically accurate methods for classifying and detecting menstrual cycle phases is necessary to better understand the potential links between hormonal fluctuations and injury risk.
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.

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.

The human individual responds as an entire organism to the effect of endurance training. Exercise physiologists have long documented cardiovascular, musculo-skeletal and metabolic effects of conditioning. Only recently are we beginning to understand that there are hormonal and hypothalamic changes which occur with conditioning. These hormonal changes probably serve similar adaptive functions as do the other conditioning responses. Careful controlled studies need to be performed of individuals prior to, early in conditioning, and following extended periods of conditioning looking at hypothalamic function, body morphometric characteristics, psychiatric and psychological testing and menstrual cycle data in order to better understand hormonal conditioning. When hormone changes occurring with endurance training are approached in this light, the complex inter-related alterations will begin to form a pattern. Further studies are needed to document the dynamic and reversible nature of these hormonal adaptations.
Reproductive change during conditioning exercise (physical training provides a model of hypothalamic adaptation to alterations in the external and internal environment. Parallels exist between the reproductive changes with exercise and those occurring with physical illness, undernutrition and psychological trauma. Although menstrual cyclicity may be disrupted in younger women, luteal phase shortening, anovulation and decreased premenstrual symptoms within normal ovulatory cycles are the most frequent observations noted. Baseline LH, prolactin and oestradiol tend to be lower, and other hormones unchanged, in trained women. Testosterone may be decreased within the normal range in men. Recent evidence shows that LH pulse frequency, amplitude and area under the LH curve are decreased in both female and male runners. Interrelationships between increases in central dopamine, endorphin and probably some hypothalamic message(s) relating to nutritional state appear to modulate these reproductive changes. The clinical and therapeutic response to reproductive alterations in the context of exercise differs when these are seen as adaptive and not as disease processes (Prior and Vigna, 1985b).
