Menstrual Cycle Tracking

Optimize training and recovery loads to the specific needs of female athletes with integrated menstrual cycle tracking system

Hormonal changes during the menstrual cycle impacts mood, energy levels, risk of ACL injuries and female athlete’s ability to train and perform


Phases and symptoms of the menstrual cycle reflect hormonal changes that determines how female athletes can adapt to workload at different points of their cycle. Monitoring the menstrual cycle helps coaches to plan light, heavy workloads and recovery according to each athlete’s individual cycle, and thus and maximize performance while minimizing the risk. (Adapted from: Keay, 2019) helps you easily track menstrual cycle, monitor phases, detect symptoms, mitigate risk, and maximize athletic potential safely

Why Monitor Menstrual Cycle?

Regardless of how much exercise training a female athlete is undertaking; menstrual cycles should be reasonably regular. If this is not the case, then prompt action is important to identifying any underlying medical issue, or imbalance in training load, nutrition and recovery.

Fluctuating hormones are driving the adaptions to training, and can have large impact on the athlete’s emotions and mood.

The athlete’s capacity to tolerate and adapt to training loads will change at different phase of her cycle, monitoring the current and historical menstrual cycle, and adapting load and recovery based on the individual cycle, is essential to predict when the athlete will be physically and/or psychological tired and most at risk, or when athletes will be ready to perform and adapt to heavy workloads.

Monitor. Understand. Optimize

By closely monitoring menstrual cycles, you’ll be able to better understand how each athlete adapts to workload during each of menstrual phases, and: 

  • Target high intensity training in the early follicular phase
  • Focus on strength development during the late follicular and ovulation phases
  • Implement knee stability exercises to reduce the risk of ACL injuries during ovulation phase
  • Explain mood changes and disrupted wellness response during luteal phases
  • Plan recovery phases during the late luteal phase
  • Prevent relative energy deficiency in sport (RED-S) by early detection of menstrual irregularity/change nature menstruation
  • Detect irregular, light or loss of menses, which requires medical referral to exclude medical conditions and support diagnosis of relative energy deficiency in sport RED-S (part of female athlete triad)
  • Detect PCOS (polycystic ovary syndrome), a medical condition that may require medical attention

Built on the Latest Science

Developed in partnership with Dr Nicky Keay, one of the world’s leading expert on female athlete health, AthleteMonitoring’s menstrual cycle tracker incorporates the latest research.  It streamlines the monitoring of key indicators of a woman’s menstrual cycle, and the detection of cycle disruption, and underlying hormonal medical issue.

Phases of the menstrual cycle

  • Early follicular phase
  • Mid follicular phase
  • Late follicular phase
  • Ovulation
  • Luteal phase

Cycle disruption

  • No menstrual bleed for 3 cycles or more (requires medical investigation)
  • Unusually light period (possible RED-S)
  • Unusually heavy periods (possible PCOS or fibroids: may require medical investigation)
  • Unusual pain during menstrual bleed (possible endometriosis: may require medical investigation)

Did you know?

Almost all female athletes reports menstrual cycle-related symptoms, and 67% of them consider these symptoms as significant performance impairements

Findlay RJ, Macrae EHR, Whyte IY, et al: British Journal of Sports Medicine, 2020 in practice

Athletes record their menstrual cycle-related symptoms (pain and bleeding) every morning on their smartphone

Menstrual phases, irregular cycles and potential medical issues are automatically detected by the system. Automated alerts and dashboard highlights athletes that warrant immediate individual attention, offer quick access to data and proactive recommendations

Coach and healthcare professionals can easily interpret risk and monitor menstrual cycles on team dashboard using preferred metrics and customizable graphs
Coach  and healthcare professionals can immediately contact athletes’ whose menstrual cycle needs attention, and make proactive workload adjustments to minimize risk, speed up recovery or optimize performance and health

Watch the webinar!

During this webinar, you’ll learn the latest women health’s science and the potential significance of menstrual status and phases of menstrual cycle on wellbeing, injury risk and performance. You’ll also learn best practice tips to adapt training type/load according to individual female athlete wellness report and mitigate the risk of ACL injury and overtraining by taking the phase of cycle into consideration.
