Erythropoietin, called EPO, is banned from sports because of claims it can enhance an athlete's performance unfairly.
A systematic review couldn't find any benefit but it found considerable risk of harm.
Professional cycling remains a popular sport though its image has been tainted by high-profile doping cases. EPO, a blood-cell stimulating hormone, recently made headlines, when the self-appointed United States of America's Anti-Doping agency (USADA) claimed that it was used by record seven-time Tour de France winner Lance Armstrong.
11 articles in the December issue of Neurosurgical Focus are dedicated to concussions in sports, focusing on methods of diagnosing concussion and evaluating its consequences, structural and functional changes that can occur in the brain following concussion, and changing attitudes and legislation concerning sports that traditionally carry risks of brain injury.
Concussion, also called mild traumatic brain injury (TBI) by virtually no one outside concussion article writing, has been hyped into a "silent epidemic" in 2012 because the event and its consequences, such as cognitive and behavioral changes, may be subtle and are not always recognized, which means they can be correlated to almost anything.
It's football season so along with cheers and yelling you will hear a more dangerous sound; the sharp crack of helmet-to-helmet collisions. Hard collisions can lead to player concussions but the physics of how the impact of a helmet hit transfers to the brain is not yet well understood.
A research team has created a simplified experimental model of the brain and skull inside a helmet during a helmet-to-helmet collision. The model illustrates how the fast vibrational motion of the hit translates into a sloshing motion of the brain inside the skull.
Most people regard journalists as biased, though it is most evident in the bias of journalists at places politically different from the consumer - in the US, MSNBC viewers regard Fox News consumers as biased while Fox News consumers regard everyone else as biased.
Science media does not have this issue because everyone votes the same way politically and it makes no difference; except on political issues that attract political demographics, like GMOs or climate change, science media can stick to science. What about sports? Can a sports journalist be biased?
They can. It just may not be evident when it comes to their sports coverage.
San Francisco Giants outfielder Melky Cabrera, coming off an an All-Star Game MVP award, had unusually high testosterone levels to go along with his .346 batting average and 11 home runs. These are not the days of Steve Howe (1), when baseball could try to ban players only to have the unnaturally powerful Player's Union block any efforts at a drug policy, Cabrera was suspended for 50 games.
Everyone talks about punches to the brain but not as much research goes into the neuroscience of sports punishment delivery systems.'
Researchers from Imperial College London and University College London are taking their shot at it. They took brain scans which revealed distinctive features in the brain structure of martial arts experts, which they say could be linked to their ability to punch powerfully from close range.
Those differences in the structure of white matter – the connections between brain regions – were correlated with how black belts and novices performed in a test of punching ability.
An April 29, 2011, a low split-finger fastball thrown by Yankees right-handed pitcher Freddy Garcia inspired a whole science study.
Want to get in a fight in Scotland?
Okay, just about anything will get you into a fight in Scotland but if you want a guaranteed way to get a headbutt and then kicked when you are on the ground, tell them they did not invent golf, the world's most frustrating pastime.
Can anyone accurately forecast the result of the London Olympics while they are a week away?
Even more daring, can they forecast results without in depth knowledge of athlete training?
Economists at Ruhr-Universität Bochum are taking a shot at it and, if it sounds like complete madness, we'll go ahead and spoil it and tell you they believe that China, USA, and Russia will top the score table with 102, 100, and 71 medals, respectively, so you can move on to another article.
But if you are interested in the nuts and bolts, read on. You can decide if this is mumbo-jumbo or solid science.
The two most common swimming strokes used by athletes training for the Olympic Games either pull the swimmer through the water like a boat paddle or whirl to the side like a propeller.
Which arm motion works best is a big argument among elite swimmers and their coaches but a university research study has picked a winner - which will be no comfort at at all to actual athletes and their coaches.
