What is an alternative effect of intense exercise during pregnancy for female athletes?

Intense exercise during pregnancy can lead to a higher risk of joint strain. This is primarily due to the hormonal changes that occur during pregnancy, particularly the increase in relaxin hormone, which helps to loosen ligaments and prepare the body for childbirth. While this can help accommodate a growing baby and prepare for delivery, it also means that joints may be more susceptible to strain and injury during intense physical activity.

With the body's joints being more mobile but less stable, movements that were previously safe may pose a greater risk for injury. Concerns for athletes include the potential for overuse injuries or strains that could affect performance or lead to longer-term issues if not properly managed. It's crucial for pregnant athletes to listen to their bodies and adjust their training regimes to minimize this risk, ensuring that exercise remains safe for both the mother and the developing fetus.
