Caffeine: Good for Energy, Good for Memory

Caffeine has long been a much-debated pre-workout energizer. Adults ponder whether the drug found in an infinite number of beverages and foods—from chocolate to soda to, of course, coffee—is actually beneficial to their training. When you dig into the facts behind caffeine, the research is undeniable: It is effective. Period. But now, a new study backs up a premise that has been gaining steam over the last few years: Caffeine can be good for your brain, too.

A study published in the Journal of Alzheimer’s Disease shows that caffeine can have a significantly beneficial effect against the production of beta amyloid, which is a sticky protein that can clog the brain. Caffeine, dosed at the range achieved in four-to-five cups of coffee daily, helps prevent this protein build-up and subsequent blockage.

This study backs several others that have shown similar benefits for cognitive function. So if you’re a fan of caffeine before training, rest assured you’re doing yourself some good. If you haven’t tried caffeine before and are a healthy adult, feel free to start slow—a half cup to one cup of coffee before workout—and see how you feel.

Along with the benefits to your brain, caffeine has been proven for decades to reduce muscle fatigue and increase exercise endurance. Just be sure to not overdo your intake or you might find yourself with the jitters. Train hard!

    Caffeine has always improved my swimming performance. In 2004, the World Anti-doping Agency removed caffeine from the list of banned stimulants. They are still monitoring caffeine usage to “detect patterns of misuse of caffeine in sport.”

    CAUTION:  A blanket statement of encouraging the use of coffee is a bit reckless. There may a benefit to some caffeine, but it can wear out the myelin sheath of the nerves and seriously agitate the whole nervous system and stress the  kidneys. Caffeine is a vasodiolator, opening up the blood vessels, but long term use can also weaken them. Caffeine in coffee is also very acidic, causing an inflammation response which is never good. Besides some people struggle with sleeping restfully and caffeine is frequently a cause.  So, again, use very cautiously-any stimulant. good blended tea is a bit better and avoid the sugars to make it taste better.
