While studying the impact of menstruation on female athletes is valuable, it is important to recognise that it is not the sole factor influencing women’s performance and injuries. Men also experience hormonal fluctuations, and research on male athletes encompasses more than just that aspect.

The Spanish article titled «Training According to the Menstrual Cycle? More Business than Science» addresses the current trend of planning athletic practice based on the menstrual cycle and questions its scientific foundation.

The article emphasises that hormonal realities differ for each woman and can vary even from month to month, casting doubt on the effectiveness of recommendations provided by apps and social media gurus, as even doctors struggle to accurately determine a woman’s specific menstrual phase without invasive methods.

The lack of high-quality research on performance and menstrual cycle-related injuries in female athletes is highlighted, exposing the absence of a solid scientific basis for the monetisation surrounding this topic. While the menstrual cycle may impact athletic performance, it is crucial to consider the scientific theoretical basis when applying personalised recommendations.

Regarding hormonal peaks and exercise type, the article mentions that strength training is recommended during the first phase of the cycle due to increased estrogen levels, while endurance exercise is considered more suitable during the second phase due to progesterone dominance. However, studies on the relationship between these hormonal peaks and injuries reveal conflicting conclusions, lacking conclusive evidence.

In summary, this article prompts reflection on the need for a solid scientific basis when planning training according to the menstrual cycle. While the recommendations may be useful for women familiar with their cycle and specific goals, it is vital to consider the scientific evidence supporting these recommendations.

If you understand Spanish, I encourage you to read the full article and reflect on this topic in the field of sports. Additionally, I wish to highlight Dr. Eva Ferrer’s work; women like her encourage us to question the intentions behind certain innovations and broaden the focus of studies.
