Ready to be shocked? A groundbreaking study reveals a surprising link between a female athlete's menstrual cycle and the severity of sports injuries. Published on December 17, 2025, this research flips the script on what we thought we knew about women's sports injuries.
This study, published in the Frontiers in Sports and Active Living journal, focused on FC Barcelona women's football players over four seasons, from 2019 to 2023. The findings are clear: while menstruation doesn't necessarily make injuries more likely, it significantly impacts how severe they are and how long it takes to recover.
Lead author Eva Ferrer, a sports medicine and female health specialist, stated, "We show that menstruation itself does not increase how often injuries happen." But here's where it gets interesting: injuries sustained during menstruation resulted in a staggering three times more recovery days compared to injuries sustained at other times in the cycle.
For instance, soft tissue injuries (think muscles, tendons, and ligaments) took over three times longer to heal when they occurred during bleeding days. The study showed 684 days lost per 1,000 training hours versus 206 days lost per 1,000 training hours outside of menstruation. That's a huge difference!
So, what can be done? Ferrer suggests that small adjustments could make a big difference. This includes longer warm-ups, adjusting high-speed workload, and providing added recovery support.
But how does the menstrual cycle change the body? It's all about hormones! As hormone levels fluctuate throughout the cycle, they impact various bodily systems, including muscles, metabolism, and the immune system. Low estrogen levels, for example, can hinder muscle repair and increase fatigue, pain, and sleep problems. Iron loss can also reduce stamina and slow down recovery.
This isn't the first time hormonal changes have been linked to worse outcomes in sports injuries, especially in women's football. FIFA is even funding a separate study to investigate the link between the menstrual cycle and anterior cruciate ligament injuries.
Simon Augustus, a researcher on the FIFA project, noted, "We know hormones fluctuate during different phases of the cycle, but we don’t yet know how much of an influence that may have on the risk of injury." The research team will be specifically monitoring estrogen and progesterone levels, which have previously been linked to increased ligament laxity and decreased neuromuscular reaction times.
