The menstrual cycle: What’s normal

Module aims

  • Provide an outline of the menstrual cycle and the hormones involved, including what you can expect during the primary three phases (follicular phase, ovulation, luteal phase)
  • Deliver insight on how the menstrual cycle may influence training and performance according to the latest research
  • Describe the signs and symptoms of menstrual irregularities and highlight when to seek further help from a medical practitioner


  • The menstrual cycle is more than just a period, it’s a complex interaction of hormones with three primary phases (the follicular, ovulation and luteal phase).
  • A normal menstrual cycle is between 21-35 days in length, occurs on a regular schedule, and includes 3 to 7 days of menstrual bleeding around ~50mL in volume.
  • The menstrual cycle can influence athletic performance, although its effect can vary between athletes, highlighting the importance of tracking your period.
  • Tracking your period is important as an athlete and can be managed in many ways including on paper, or via one of our recommended applications.
  • You should seek the advice of a specialised women’s health GP if you experience any of the undesirable signs and symptoms outlined.
