Abstract

Objectives: The menstrual cycle can affect sports participation and exercise performance. There are very few data on specific menstrual cycle symptoms (symptoms during various phases of the cycle, not only during menstruation) experienced by exercising women. We aimed to characterise the most common symptoms, as well as the number and frequency of symptoms, and evaluate whether menstrual cycle symptoms are associated with sporting outcomes. Methods: 6812 adult women of reproductive age (mean age: 38.3 (8.7) years) who were not using combined hormonal contraception were recruited via the Strava exercise app user database and completed a 39-part survey. Respondents were from seven geographical areas, and the questions were translated and localised to each region (Brazil, n=892; France, n=1355; Germany, n=839; Spain, n=834; UK and Ireland, n=1350; and USA, n=1542). The survey captured exercise behaviours, current menstrual status, presence and frequency of menstrual cycle symptoms, medication use for symptoms, perceived effects of the menstrual cycle on exercise and work behaviours, and history of hormonal contraception use. We propose a novel Menstrual Symptom index (MSi) based on the presence and frequency of 18 commonly reported symptoms (range 0–54, where 54 would correspond to all 18 symptoms each occurring very frequently). Results: The most prevalent menstrual cycle symptoms were mood changes/anxiety (90.6%), tiredness/fatigue (86.2%), stomach cramps (84.2%) and breast pain/tenderness (83.1%). After controlling for body mass index, training volume and age, the MSi was associated with a greater likelihood of missing or changing training (OR=1.09 (CI 1.08 to 1.10); p≤0.05), missing a sporting event/competition (OR=1.07 (CI 1.06 to 1.08); p≤0.05), absenteeism from work/academia (OR=1.08 (CI 1.07 to 1.09); p≤0.05) and use of pain medication (OR=1.09 (CI 1.08 to 1.09); p≤0.05). Conclusion: Menstrual cycle symptoms are very common in exercising women, and women report that these symptoms compromise their exercise participation and work capacity. The MSi needs to be formally validated (psychometrics); at present, it provides an easy way to quantify the frequency of menstrual cycle symptoms.

  • Cyclic hormone changes can affect physical and psychological attributes and may influence sports performance, although the effects are highly individual.

    “These cyclic hormone changes can affect a number of physical and psychological attributes and, ultimately, may influence sports performance, although the effects are highly individual [88,90,91].”

    From International society of sports nutrition position stand: nutritional concerns of the female athlete (2023) · cites this paper as [90]

    The Results (Abstract, p. 1) report physical and psychological menstrual-cycle symptoms and associate greater symptom burden with missed training or competition. Strengths and Limitations (p. 10) describes menstrual cycles and symptom timing as individual. The study did not measure cyclic hormone changes or establish that those changes caused the symptoms or affected sports performance. (LLM, conf=0.86)

  • There is a greater effect of sex hormone suppression of gluconeogenesis output during exercise during the active pill weeks of COC users and during the luteal phase of the menstrual cycle of eumenorrheic women.

    “This recommendation is particularly prudent during the active pill weeks of COC users and during the luteal phase of the menstrual cycle of eumenorrheic women, where there is a greater effect of sex hormone suppression of gluconeogenesis output during exercise [90,166].”

    From International society of sports nutrition position stand: nutritional concerns of the female athlete (2023) · cites this paper as [90]

    The Survey analysis (p. 3) and Strengths and Limitations (p. 11) mention general metabolic effects of combined hormonal contraceptives, but the study excluded their users. Searches for gluconeogenesis and glucose production found no passage addressing suppression during exercise or comparing active pill weeks with the luteal phase. (LLM, conf=0.76)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
