A new study shows that caffeine improves the strength and stamina of people exercising. The study comes from England. Thirteen healthy young men were given a caffeine drink an hour before their workout. They did the same workout later, drinking a beverage without caffeine. They repeated the routine several times over a number of days.
After swallowing the caffeinated beverage, the men completed significantly more repetitions of the exercises. They also reported feeling less tired during the entire program and said that they were eager to repeat the whole workout again soon.
Experts know that a cup of coffee before a workout improves athletic performance, especially in endurance sports like distance running and cycling. Caffeine is legal in the Olympics. More than two-thirds of 20,680 athletes in a recent study had caffeine in their urine. The highest use is among triathletes, cyclists and rowers.
Experts do not know exactly how the caffeine works to improve performance. They are continuing their studies.
One scientist concluded that caffeine before exercise will probably give everyone a better workout.
