Heading a football changes blood patterns in the brain, according to new study

A study published in the journal Brain Injury reveals that playing football can alter blood patterns in the brain. Researchers analyzed blood samples from professional footballers and found changes in micro RNA levels after heading the ball. Micro RNAs are crucial for protein production and cell function, and their alteration is linked to cognitive functions and Alzheimer's disease. The study suggests that micro RNAs could serve as biomarkers for detecting brain injuries. In response to such findings, the Football Association in England has limited high-force headers in training sessions.

What did the study published in the journal Brain Injury find about professional footballers?

• They have higher levels of physical fitness.

• Their brain patterns change after heading the ball.

• They are more prone to muscle injuries.

• Their cognitive abilities are superior.

What is the primary function of micro RNAs in cells?

• To increase the number of cells.

• To destroy harmful bacteria.

• To enhance cell division.

• To help cells control protein production.

How can micro RNAs be potentially used in the medical field according to the study?

• To cure cancer.

• As biomarkers to detect brain injury.

• To improve athletic performance.

• As a treatment for Alzheimer's disease.

What new guideline did the Football Association in England introduce?

• Banning all headers in training.

• Limiting high-force headers to 10 per training session.

• Reducing the number of players on the field.

• Increasing the number of headers in matches.

What was the response of former Tottenham manager Esperito Santo to the new guidelines?

• He publicly admitted ignoring them.

• He criticized them for being too strict.

• He fully supported them.

• He implemented them immediately.
