Summary

Elite female swimmers show low menstrual dysfunction rates. Body composition, not training intensity, appears key to menstrual health in athletes.

Area of Science:

  • Sports Medicine
  • Exercise Physiology
  • Female Athlete Health

Background:

  • Menstrual dysfunction is a concern in female athletes, particularly in endurance sports.
  • Previous research suggests a link between high training volume, low body fat, and menstrual irregularities.
  • The specific impact of training load versus body composition on menstrual function in elite swimmers requires further investigation.

Purpose of the Study:

  • To investigate the incidence of menstrual dysfunction among elite female swimmers.
  • To explore the relationship between training load, body mass, and menstrual irregularities in this population.
  • To identify key factors influencing menstrual function in elite swimmers.

Main Methods:

  • A questionnaire-based study was conducted with 140 female elite swimmers from the Danish Swimming Association.
  • Data collected included menstrual history, training details, and body mass.
  • Statistical analysis compared swimmers with and without menstrual dysfunction (oligomenorrhoea).

Main Results:

  • A low incidence of menstrual dysfunction (16%) was observed, lower than in other endurance-trained female groups.
  • Intense physical training did not delay menarche onset in these swimmers.
  • No significant difference in adjusted body mass was found between swimmers with oligomenorrhoea and those with normal menstruation.

Conclusions:

  • Elite female swimmers exhibit a low prevalence of menstrual dysfunction.
  • Body mass and body fat content appear to be more significant factors in menstrual function than training volume or psychological stress.
  • Findings suggest that maintaining adequate body composition is crucial for menstrual health in elite swimmers.
