...Fuel for these diesels is probably very expensive but a lot of that can be taken from captured ships...
...promise of energy drinks is pretty irresistible - push your body, work hard, sweat buckets, and if you need an extra boost, down a bottle or two of liquid fuel to drive you through the rest of your workout...
...Makes sense, since the drinks provide your body with carbohydrates in the form of sugars - the fuel that cells and tissues like muscle need to keep working. But exercise experts say that despite what you may think, energy drinks have no effect at all on your tired muscles. Instead, when your energy is petering out, a swig of an energy drink works on the brain to keep you inspired and motivated to push on. (Read "China Says 'Keep Out' to Coca-Cola...
...Chambers decided to test this theory after a 2004 study found that energy drinks enhanced athletic performance even in short periods of physical activity. Intuitively, this makes sense, but physiologically, it doesn't. The human body is capable of generating enough fuel in the form of glucose to sustain itself, even in vigorous exercise, for about an hour. So in short periods of activity, energy drinks shouldn't have any effect on performance. Added carbs from drinks would be useful only after several hours of exertion, when the body starts to draw upon its stored glucose, known as glycogen...
...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...
