Heading a soccer ball could be more dangerous for female players

Soccer is played by millions of people across the globe, but a new study shows a particular move—heading the ball—may be more hazardous for female players than male ones, NPR reports. Scientists compared MRI images of women and men with similar ages and exposure to heading, and they found that female players show more changes to white matter in the brain—suggesting women may be more sensitive to repetitive hits to the head, they report this week in Radiology. Scientists are unsure why frequent exposure to heading affects women more, but they hope to learn the answer in the future.
