Technique may lead to earlier diagnosis, tracking of brain disorders in athletes

Sports-related concussions and mild traumatic brain injuries have grabbed headlines in recent months, as the long-term damage they can cause becomes increasingly evident among both current and former athletes. The Centers for Disease Control and Prevention estimates that millions of these injuries occur each year.

Despite the devastating consequences of traumatic brain injury and the large number of athletes playing contact sports who are at risk, no method has been developed for early detection or tracking of the brain pathology associated with these injuries. (more…)

‘Weakest Links’ Show Greatest Gains in Relay Races

EAST LANSING, Mich. — The inferior members of swimming or running relay teams – those athletes who fared poorest in individual races – showed the greatest gains when performing as part of a team, and those gains were even greater during final races as opposed to preliminary races.

The new research from Michigan State University’s Deborah Feltz and Kaitlynn Osborn provides some of the first real-world support for the Köhler motivation effect, which describes how less capable individuals perform better when performing a task with others as opposed to individually. (more…)

‘Runner’s High’ Played a Role in Human Evolution

Aerobic exercise triggers a reward system in the body of long-distance running creatures like humans and dogs, but not ferrets, a study led by UA anthropologist David Raichlen suggests.

In the last century, something unexpected happened: Humans became sedentary. We traded in our active lifestyles for a more immobile existence.

But these were not the conditions under which we evolved – our hunter-gatherer predecessors were long-distance endurance athletes. (more…)

Former Football Players Prone to Late-Life Health Problems, MU Study Finds

*Healthy dietary habits can improve long-term health of collision-sport athletes*

COLUMBIA, Mo. – Football players experience repeated head trauma throughout their careers, which results in short and long-term effects to their cognitive function, physical and mental health. University of Missouri researchers are investigating how other lifestyle factors, including diet and exercise, impact the late-life health of former collision-sport athletes.

The researchers found that former football players experience more late-life cognitive difficulties and worse physical and mental health than other former athletes and non-athletes. In addition, former football players who consumed high-fat diets had greater cognitive difficulties with recalling information, orientation and engaging and applying ideas. Frequent, vigorous exercise was associated with higher physical and mental health ratings. (more…)

Research Reveals New Secret Weapon For Le Tour

Winning margins in the Tour de France can be tight. In 2010 just 39 seconds separated the top two after more than 90 hours in the saddle. When every second counts, riders do all they can to gain competitive advantage, from aerodynamic carbon fibre bikes to the latest sports nutrition.

Now there could be a new, completely legal and rather surprising weapon for riders aiming to shave vital seconds off their time – beetroot juice. (more…)

Beetroot Juice Could Help People Live More Active Lives

New research into the health benefits of beetroot juice suggests it’s not only athletes who can benefit from its performance enhancing properties – its physiological effects could help the elderly or people with heart or lung-conditions enjoy more active lives.

Beetroot juice has been one of the biggest stories in sports science over the past year after researchers at the University of Exeter found it enables people to exercise for up to 16% longer. (more…)
