Coffee reduce bloody flow
Just when you thought that cup of coffee before the race was a good idea, here comes another study to make you think twice. This study actually is about a year old, so maybe that explains how you felt while racing on a coffee high last year. Read the entire article at BeverageDaily.com.
Drinking caffeine drinks appears to stifle the body's ability to boost blood flow to the heart during exercise, suggests new research out of Switzerland.Blood flow to the heart has to increase during exercise in order to match the increased need of oxygen. But when 18 healthy people were given the equivalent of two cups of coffee, scientists found that blood flow increase during exercise was much lower than when they exercised without having consumed coffee.This effect was even stronger when the participants were in a chamber simulating high altitude, said the scientists at the University Hospital in Zurich.They say that although caffeine drinks are known to stimulate the brain, their results show that caffeine is unlikely to boost athletic performance.
