- Can Caffeine in Large Doses Improve Athletic Performance?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: Is there any truth to the idea that caffeine in large doses can
- improve athletic performance?
-
- ------------------------------------------------------------------------------
-
- ANSWER: As a stimulant, caffeine is a double-edged sword that may enhance
- your performance in endurance activities (long distance events) but poses
- greater health risks that far outweigh any slight performance benefits.
- Hence, it is banned by the International Olympic Committee if present in the
- urine by more than 15 mu_g/ml. It does not significantly improve performance
- for maximal short-term exercise bouts.
- Caffeine supposedly assists in endurance events by stimulating the
- central nervous system (increasing alertness), increasing the breakdown of
- fatty acids (instead of muscle glycogen for energy), and increasing muscle
- contraction. Meanwhile, caffeine also masks fatigue, an important warning
- sign, which may fool athletes into thinking they are performing better. But
- for the body, it's a different story.
- Headaches, tremors, nervousness, increased urine production and heart
- beat irregularities are harmful effects of caffeine used even in the 200 to
- 500 mg range. And these dangers increase in severity as the dosage is
- increased. Even die-hard endurance athletes would admit that such
- caffeine-induced symptoms as increased urine production, irritability, dry
- mouth, ringing in the ears, impaired sense of touch, increased muscle pain,
- headache and heart beat disturbances probably cancel out any supposed
- advantages towards increased endurance performance.
- In medicine, much as in life, there always seems to be a price that must
- be paid for every desired effect. Sometimes, the advantage is just not worth
- the cost.
