Caffeine is probably the most widely used ergogenic aid of all times. It has made many fortunes. Imagine the World without caffeine? A U.S. based prohibition on caffeine like they did on alcohol in the thirties? Organized crime would even get stronger, for sure! Here is what you should know about the latest findings on caffeine:
1. Its positive effects on sports performance mainly come from enhanced mood, reduced perception of pain, and adenosine antagonism.
2. For best results, capsules work better than tablets, and the optimal time is 45 to 60 minutes before exercise. Using a mixture of 2 ounces of club soda with two ounces of grapefruit juice to swallow them will increase the speed and the magnitude of coffee concentration in the blood stream.
3. For endurance improvement, only 1.3 to 2 mg/kg seems to be enough to increase performance, probably due to increased fatty acid metabolism and glycogen sparing.
4. For strength training, best results are seen once the 7 mg/kg threshold is reached, with 10 mg/kg being the upper limit where no further additional gains are seen. Elite athletes tend to respond better to caffeine than weekend warriors. Using coffee as your sole source of caffeine pre-workout would require an enormous amount of coffee. As in 6-9 cups for a 90 kg lifter. Capsules remain the best option.
5. Caffeine eliciting dehydration is a myth. Research studies show no greater change in urine loss or fluid when compared to a placebo.
6. Even though caffeine raises blood pressure short term, caffeine and hypertension are not related in long term studies.
7. The polyphenols in coffee improve insulin sensitivity, but caffeine in large amounts may negatively alter insulin sensitivity, but the jury is not out yet on whether caffeine use in athletes increases diabetes risk.

Chicago most caffeinated U.S. city: survey

The windy city is also the most wired, according to a survey that showed people in Chicago are the most caffeinated in the United States.
Chicagoans eat more chocolate and drink more cola than other U.S. urbanites, and are among the top consumers of energy drinks and coffee.
They are also likely to say caffeine is good for you, according to the poll conducted by Prince Market Research.
Tampa, Miami, Phoenix and Atlanta rounded out the top five most caffeinated cities, while residents of San Francisco, Philadelphia, New York, Detroit and Baltimore consumed the least caffeine.
"It's surprising perhaps that some places you may think have a lot of hustle and bustle like San Francisco, Philadelphia and New York, were the least caffeinated cities," said Todd Smith, a spokesman for HealthSaver, a healthcare discount service that commissioned the poll.
The survey looked at consumption of coffee, tea, chocolate, sodas, energy drinks and caffeine pills in 20 major cities in the United States by interviewing 2,000 people.
Seattle took the top spot in just caffeinated coffee consumption. Nearly 60 percent of residents in the city said coffee would be the most difficult caffeine product to give up.
The growing popularity of "high-end" coffees, energy drinks and green tea has added to more caffeine consumption around the world, according to HealthSaver.
Half of all the people questioned in the poll said they drank coffee every day, followed by 21 percent who drank caffeinated cola.
New Yorkers and San Franciscans were also among people most likely to say caffeine is bad for you. More than 70 percent of people questioned in the poll said they were not addicted to caffeine. The older the age group the more likely they were to say coffee would be the most difficult caffeinated product to give up.
