Coffee and
Caffeine
By Keith B.
Wheeler, Ph.D.
And Angeline
M. Cameron
Q: Will
a cup of caffeinated coffee enhance athletic
performance? Does caffeine have any
undesirable side affects? Why do so many
people drink coffee?
A: No,
consuming one cup of caffeinated coffee will not enhance athletic
performance. Some studies have suggested
that caffeine will enhance performance under certain circumstances
(ie, short-term high-intensity or long-term moderate-intensity
exercise). However, most studies have
demonstrated no effect of caffeine on endurance and
performance. In the studies that suggest an
effect, the caffeine consumption usually exceeded 400 mg before
exercise. To get this level of caffeine,
you would have to consume approximately 4 cups (5 oz) of
caffeinated coffee, 12 cups (5 oz) of tea, or 3 quarts of
cola.
Consuming
caffeine can have some undesirable side effects, including
increased heart rate, digestive secretions, breathing rate, and
urine output. Caffeine also affects the
central nervous system by increasing
restlessness. Other side effects include
headaches, irritability, insomnia, diarrhea, hyperactivity, and
depression. Keep in mind also that caffeine
is recognized as a stimulant by the International Olympic
Committee, and if present in excessive amounts is considered a
banned substance.
Most people
drink coffee because they like the taste, and it is a socially
acceptable ritual.
