...What we are suggesting is a central-governor model," says Ed Chambers, one of the study's co-authors and a researcher at the School of Sport and Exercise Sciences at the University of Birmingham. "Ultimately, the brain controls exercise performance by controlling the neural outflow to the exercising muscles...
...asked one group to rinse with a sugar-based drink and another to rinse with an artificially sweetened drink. Then he took a third group of volunteers, asked each of them to rinse with the same solutions, and put them through an MRI scanner to see whether their brain reacted similarly to the two beverages...
...surprise, they did not. The sugar-drinking volunteers showed activity in the reward and pleasure centers of the brain, while those drinking the artificially sweetened beverages did not. Chambers suspects that it's this activation of the brain that explains the enhanced performance effect of sugary energy drinks during short workouts. This theory is supported by other studies in which researchers infused carbohydrate sugar solutions directly into the body intravenously - in those cases, subjects experienced no improvement in their physical performance...
...Chambers' work supports the idea that the brain plays a critical role in pushing the body to achieve optimum performance. When the mouth tastes sugar, it may anticipate an influx of added fuel and therefore trigger the satisfaction and reward areas of the brain, in turn egging the body on to do more. At Loughborough University in Britain, Clyde Williams, emeritus professor of sports science, and his team found that distance runners on a treadmill selected faster running speeds after swishing with a sugared energy drink than with a placebo solution...
...spending]. And President Bush has to be held principally responsible for that. You cannot lead with your chin on social issues; they tried that a few years ago and got themselves in trouble," he says, referring to episodes like the Terri Schiavo controversy, when Congress tried to prevent a brain-dead woman in Florida from being taken off life support...
