Dr. Gregory Meyer of Cincinnati Children's Hospital has developed a protective device, the concept of which is, to put it mildly, a lot of controversial impressions. However, practical tests have shown that the technique is quite working and even beneficial. This sports accessory is called "Q-Collar" (Q-collar).
The Q-Collar looks like an arc and needs to be worn around the neck where it fits snugly around the body. So tight that it slightly compresses the jugular vein, reducing the rate of blood flow from the brain. This leads to the accumulation of fluid in this organ, due to which it swells and increases in volume. Not so significant as to provoke any effects, but it reduces the amount of empty space between the brain and the walls of the skull.
This is the whole point - for a short time, one game match, the collar allows you to reduce the range of motion of the brain inside the cranium during external impacts. The weaker the brain beats against the bone, the better. During the tests, all members of the women's junior rugby team were given personal accelerometers, and half were instructed to wear Q-Collar collars during games. At the end of the three-month playing season, the devices recorded approximately the same number of shocks and blows to the head for each player. But in girls with Q-Collar, the white matter of the brain remained intact, while in the rest its structure was noticeably deformed.
By the standards of sports, this is not an injury at all, a trifle - all microdamages in the brains of the test subjects were successfully healed just in a couple of months of rest from training. However, if there is a chance to make sure that the most important organ of the body does not suffer from blows at all, then why not try to implement it? After the publication of the research results, Dr. Gregory Mayer said that he is developing an advanced version of the Q30 Innovations collar, which will already have a commercial purpose.
