Teams of scientists are researching the unique ways that elite sport affects the female body – how breasts alter the way you run, but the right sports bra could give you the edge; how the menstrual cycle could impact performance and what role period trackers could play; and why is there a higher risk of some injuries, and what can be done to avoid them?
Actually, relaxin peaks during the luteal phase (days 14-28) of the cycle, not just within 2 weeks of ovulation. Studies show ACL injuries are 2-8x more common in female athletes partly due to these hormonal flucuations. Some teams are now adjusting training intensity based on cycle phases to reduce injury risk.
