Coffee before Exercise
According to CNN.com there are five reasons to drink coffee before your workout.
A Spanish study, published in the International Journal of Sport Nutrition and Exercise Metabolism, found that trained athletes who took in caffeine pre-exercise burned about 15% more calories for three hours post-exercise, compared to those who ingested a placebo.
According to the report the necessary amount of caffeine to gain this effect is 4.5 mg per kilogram of body weight. For a 154 pound person this comes to 250 mg of caffeine in a 12 ounce cup. Additionally researchers in Japan have shown that blood flow is increased for an hour and a quarter after drinking coffee with caffeine. And, it turns out that drinking two to three cups of coffee before exercise resulted in less perceived pain from a hard workout.
Athletic Performance and Coffee
We wrote recently about how coffee enhances athletic performance. We noted that drinking coffee increases adrenaline. Adrenaline increase heart rate and blood flow, increases blood flow specifically to the brain and helps improve short term speed and endurance. Scientifically, the caffeine in coffee is an ergogenic aid for sustaining a high degree of effort over the short term.
