Caffeine increases endurance during long events such as a marathon, triathalon or bicycle race. At rest,
caffeine is a diuretic, but during exercise it does not increase urination. In short
races, it makes athletes faster by causing the brain to send messages along nerves to
cause a greater percentage of muscles fibers to contract at the same time. Caffeine
loses its beneficial effects with repeated exposure, so athletes who want to gain maximum advantage
from caffeine during competition should avoid drinking caffeinated beverages when they are not exercising.Subscribe nike tn to

with caffeine were able to absorb and use 26 percent more of the ingested sugar
than those who took the same drinks without caffeine.Previous studies show that caffeine helps athletes
run faster in both short and long-distance races. When muscles run out of their
stored sugar, they hurt and become more difficult to coordinate. Muscles get their
energy from sugar and fat in the bloodstream, and from sugar, fat and 925 silver protein stored
in the muscles. Most research shows that it doesn't take much more than
one or two soft drinks to increase endurance. Gabe Mirkin has been a radio talk
show host for 25 years and practicing physician for more than 40 years; he is
board certified in four specialties, including sports medicine. In longer races, it delays fatigue
by preserving stored muscle sugar. A study from the University of Birmingham in England
shows that caffeine helps the body use more carbohydrates from drinks that you take during
exercise (Journal of Applied Physiology, June 2006). Caffeine is a potent stimulant which
can cause irregular heartbeats in people who already have heart disease, and raise blood pressure
in people with hypertension. Caffeine causes muscles to burn more fat, thus sparing stored
muscle sugar to delay fatigue.Nobody really knows how much caffeine you can take in
