Tuesday Quick Hits (UPDATED)

Bending the rules for a star is not uncommon, heck we see it almost every week in the NFL as players are initially reported to have “dirt in the eye”, or “back spasms”, etc.  However it is rare that you see an overt “relaxing” of rules to possibly allow them to play.  It has happened in the UK in Premiere League Soccer, the team is Arsenal Manchester United and the player is Rio Ferdinand (bold my emphasis);

Ferdinand claimed on Twitter that he ‘could not remember’ what happened during United’s 3-0 victory over Bolton at Old Trafford on Saturday.

He also admitted  he had suffered concussion, which under previous FA rules meant he would automatically miss the next 10 days.

But the FA have relaxed the guidelines and Ferdinand, 33, will now be put through a thorough medical examination.

Thanks to twitter both @SportsDocSkye and @SportsDoc_Chris find that the article as I have presented it and was reported in the link is inaccurate.  I appreciate them following and correcting this issue (also my stupidity when it comes to European Futbol).  The issue that needs correcting is that the current FA concussion guidelines follow the Zurich statement and a player will follow graduated return to play, meaning the 10 day issue is moot…

What Happens In a Concussion?

A  wonderful article by John Doherty of North West Indiana Times gives us the most well written explanation I could find.

In the immediate aftermath of a concussion, there may be some structural damage at the microscopic level with some cell death. However, the primary problem is a chemical one in the cells that have survived the incident.

John Doherty goes on to explain via the research of David Hovda, PhD at UCLA.

When there is a sufficient blow to the brain, the membranes of the affected nerve cells in the brain are stretched or twisted, allowing potassium to exit those cells, which triggers those cells to depolarize, thus the phenomenon of seeing stars if the affected area is involved with sight or ringing in the ears if the affected area is involved with hearing. The exit of potassium (K+) peaks approximately two minutes after the incident but continues for another 3-4 minutes.

Then, until the chemical balance is somewhat restored, Continue reading
