People nowadays are looking all over for energy because they are drained. It is easy for one to have hope in a can or bottle, because that takes very little effort other than opening it and drinking it down. That is why most people lack energy to begin with on their part. They lack an effort to eat right, exercise, socialize, push themselves, and all the other great things God gave us to be happy and full of energy. So there is my blurb on this blog.
The latest on so-called energy drinks.
Studies warn against energy drinks before workout
Thursday, August 1, 2013
Always down an energy drink before working out because it seems to really
get the blood pumping? Think again, according to new research.
Houston cardiologist John Higgins tested the effect of a 24-ounce Monster
beverage on his own heart function and the effect of the amount of caffeine
in an energy drink on the blood flow of healthy young and not-so-young
people before and after a workout. In both cases, the results were
disruptive enough to cause Higgins to advise against pre-workout
consumption.
“Energy drinks really aren’t good for you anytime, but especially before a
workout,” said Higgins, a professor at the University of Texas Medical
School at Houston. “You should have water or a sports drink instead.”
In a July paper in the International Journal of Cardiology, Higgins reported
that his cardiac blood vessels became sluggish and didn’t open as well after
drinking the Monster beverage, compared to their function before
consumption. Cardiac measurements showed function was significantly
decreased at 50 minutes and acutely decreased at 90 minutes.
In an August paper in the American Journal of Medicine, Higgins found 200 mg
tablets of pure caffeine reduced the heart’s blood flow during subsequent
exercise by 22 percent among participants whose average age was 27 and by 14
percent among participants whose average age was 58.
Higgins suspects the culprit it is not just the caffeine but its interaction
with some other ingredient in energy drinks. He will try to identify the
exact cause in future research, he said.
Higgins, who said he wasn’t hardcore enough to test on himself the vascular
effects of the not recommended but still popular pastime of mixing energy
drinks and alcohol, will present his research on the vascular effects of
caffeinated energy drinks at an Institute of Medicine workshop in Washington
next week.
