Emily Capodilupo, WHOOP SVP of Data Science & Research, and Kristen Holmes, WHOOP VP of Performance, join the podcast to discuss the perils of disregarding sex as a meaningful biological variable in research, which has implications in training, fueling, medication dosing, and so much more. Emily and Kristen discuss why there are disparities in research (3:48), how exclusion has been both systemic and practical (7:53), the role lack of research has in diagnostics and in medication dosage (13:24), how wearables are well poised to bridge the research gap (19:01), pivotal research on how exercise is beneficial to pregnant people (25:11), the impact of training and pre-sleep feeding on women (29:02), and training modulations during different phases of the menstrual cycle (32:59).
