There is currently a debate that questions whether head off is harmful to health or. The doctor. Ruiz Ocana, specialist in Neurosurgery , belies this claim.
Top with the head is not harmful for several reasons:
- Statistics. Given that football is one of the most popular sports in the world and hit the ball with the head is one of the most frequent actions, there is no news that a player has sustained a head injury during a football game, as it could be an intracranial hematoma or cerebral contusion.
- Scientific. No items to support the theory that finish with the head is harmful.
- Clinics. No clinical cases of dementia, Alzheimer's or other cognitive impairment in old football players.
- Mechanical. Top with the head is a purely mechanical blow from a hard object -the skull against a soft object or semi-the ball.
We can not forget that the brain is protected both by the bones that form the skull and the cerebrospinal fluid in which it is immersed. This allows absorb shock. This can be illustrated with a bucket full of water in which there is an apple floating. The hub would be the skull, brain apple and water the cerebrospinal fluid. It is difficult for sudden movements or shocks cube get the apple (which would be the brain) from hitting the wall of the cube.
Still, it is necessary to know that normal human skull reaches its optimum at 2 or 3 years hardness, so it is not advisable for a child of less than 4 or 5 years made head banging to a regulation ball. You can do with balls lightweight and very flexible.
What sports head is sensitive to receive blows that hurt the person?
In extreme sports especially. Especially those speed implies a coup against something hard. The kinetic energy of the moving object translates into probable brain injury.
According to statistics, the greatest risk is borne by mountain sports, motor vehicles and cycling.
