We all know that
caffeine can give you a quick boost, but it also has a mild effect on increasing
fat burning
both at rest and during exercise. It may also increase endurance and
even some types of strength training. A series of studies shows
caffeine may also consistently decrease the sensation of pain during
exercise. The research group has published 3 studies each examining the
effects different doses of caffeine intake on leg pain in men and
women. In one experiment they showed that both regular caffeine
consumers and those who did not consume caffeine experienced less leg
pain during 30 min of moderate intensity cycling exercise after
caffeine intake (equivalent to about 2-3 strong cups of coffee)
compared to placebo. In another study, they had young women exercise at
a slightly higher intensity for 30 min following intake of caffeine or
placebo. Caffeine was shown to dramatically decrease perceived rating
of leg muscle pain. In a third experiment, two doses of caffeine were
tested in women who were low caffeine consumers. Both the low and high
dose caffeine again significantly reduced leg muscle pain scores during
30 min of exercise. These studies show caffeine intake at moderate
levels has a consistent effect on reducing the sensation of pain during
moderate intensity exercise. The effect is evident in men and women and
does not depend on regular caffeine intake. It appears that caffeine
can act on the brain to block some of the uncomfortable feelings
associated with physical exertion.
