Imagine this: Your body is a finely tuned machine, and every month, a complex symphony of hormones subtly shifts the way it functions. Now, picture yourself as a professional athlete, pushing your body to its limits. A new study reveals a surprising connection between the menstrual cycle and the severity of sports injuries in female footballers. Let's dive in!
Published on December 17, 2025, this research, featured in the journal Frontiers in Sports and Active Living, uncovered a fascinating link. While menstruation doesn't necessarily make injuries more likely, it appears to amplify their impact.
The study followed the FC Barcelona women's team over four seasons, from 2019 to 2023, observing their performance in the Spanish professional national league. Lead author Eva Ferrer, a sports medicine and female health specialist, clarified a key point: "We show that menstruation itself does not increase how often injuries happen."
But here's where it gets interesting. The research showed that injuries sustained during menstruation resulted in significantly longer recovery periods. Players lost three times more days to recovery when injured during their period compared to other times in their cycle. For instance, soft tissue injuries, affecting muscles, tendons, and ligaments, took far longer to heal during bleeding days. The study documented 684 days lost per 1,000 training hours during menstruation versus only 206 days lost during other cycle phases.
So, what's happening inside the body? The menstrual cycle is a hormonal rollercoaster, with fluctuating levels of hormones impacting various systems. Low estrogen, for example, can hinder muscle repair, increase fatigue and pain, and disrupt sleep. The loss of iron during menstruation can also reduce stamina and slow down the recovery process.
“Small modifications such as longer warm-ups, adjusted high-speed workload, or added recovery support may help reduce the severity of injuries if they occur,” Ferrer suggested.
This isn't the first time hormonal changes have been linked to injury outcomes in sports, particularly in women's football. FIFA has initiated a separate study this year to investigate the connection between the menstrual cycle and anterior cruciate ligament (ACL) injuries. Researcher Simon Augustus 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 specifically monitor estrogen and progesterone levels, hormones previously linked to increased ligament laxity and decreased neuromuscular reaction times.
This is a critical area of study, and it could lead to tailored training and recovery strategies for female athletes.
