Medicine and science in sports and exercise·1995

Female sex steroids impact athletic performance, but effects vary individually. Further research is needed to optimize training and health for female athletes, considering menstrual cycle phases and oral contraceptives.

Area of Science:

  • Sports Medicine
  • Exercise Physiology
  • Endocrinology

Background:

  • Understanding of female athlete physiology is growing, but knowledge gaps remain regarding sex steroid influence.
  • Female sex steroids affect cardiovascular, respiratory, and metabolic parameters, with potential performance implications, especially for elite athletes.
  • Individual variability in menstrual cycle effects on performance necessitates personalized approaches.

Purpose of the Study:

  • To explore the influence of female sex steroids on athletic performance.
  • To examine the role of oral contraceptives (OCs) in managing menstrual dysfunction and performance.
  • To highlight the need for further research on menstrual cycle phase and OC effects in exercising women.

Main Methods:

  • Review of existing literature on female physiology, sex steroids, and athletic performance.

  • Discussion of the clinical relevance of statistically significant versus nonsignificant findings.
  • Consideration of oral contraceptive use, including lower-dose triphasic pills and newer progestins.

    • Main Results:

    • While female sex steroids influence physiological parameters, their impact on recreational athletes is likely minimal.
    • Elite athletes may experience performance differences due to subtle physiological changes related to the menstrual cycle.
    • Oral contraceptives may offer benefits for women with menstrual dysfunction, providing hormonal stability for training and competition.

    Conclusions:

    • Individual variability in response to menstrual cycle phases and hormonal interventions is critical for performance optimization.
    • Further large-scale, prospective, randomized clinical trials with accurate hormonal measurements are essential.
    • Enhanced understanding will enable better guidance for female athletes to maximize performance and ensure long-term health.
