Governor Arnold, in his first mainstream movie “Stay Hungry” said, “You must burn to grow.” Pain is a natural part of intense exercise. You feel the pain during the last few reps of intense sets during weight training, the final 100 meters in a 400-meter sprint, or the hike up a big hill to get to the lake on a backpacking trip.
Many athletes take caffeine supplements to give them extra energy and
fight muscle pain linked to fatigue. Rachael Gliottoni and Robert Motl
from the University of Illinois Urbana-Champaign found that caffeine
decreased leg pain during a stationary bike for 30 minutes at 80
percent of maximum effort. The subjects were given 5 milligrams of
caffeine per kilogram bodyweight or a placebo (fake caffeine) 60
minutes before exercise. Caffeine does not improve maximum strength and
power, but allows people to train harder and makes them feel more
energetic. Caffeine is no longer banned in Olympic sports, but is
prohibited in college sports if urine levels exceed 15 micrograms per
milliliter (two to three strong cups of coffee). (International Journal
Sport Nutrition Exercise Metabolism, 18, 103-115, 2008)
