What is it about?

Heart Rate Variability (HRV) is used as a measure to reflect both a healthy and pathological state. We were interested in whether daily measures of HRV change over the course of the menstrual cycle (MC) in healthy athletic females. We found that changes in HRV corresponded to the progesterone peak in the luteal phase of the MC.

Why is it important?

The MC is a natural process that ebbs and flows with the physiological state of the individual. Therefore it should not be a major barrier to the inclusion of women in sport and health research.


The Doyle-Baker lab group is composed of trainees that start from undergrad and go to post docs. This project involved collaboration with a former master student (Cory Fagan), completed MKIN working for the former master student (Nathaniel Minichiello) and undergraduate honours student (Renee Kokts-Porietis). The testing took place off the University campus in the TCR Sport lab. This is an example of continuing to work with former trainees who are passionate about bringing science to their clients and assisting trainees in developing their skills sets.
