Single Pre-Workout Caffeine Dose Boosts Sprint Performance for Over 3 Hours: Study
What Happened
Researchers at the University of Tsukuba found that a single dose of caffeine taken before exercise improved repeated sprint performance for at least 3.5 hours. In the study, 12 healthy adults consumed either caffeine or a placebo an hour before exercise, with the caffeine group showing higher mean and peak power output during repeated cycling sprints. The caffeine group also reported lower perceived exertion and less leg muscle pain while maintaining performance gains throughout the testing period.
Key Takeaways
The findings suggest that a single pre-event caffeine dose may help athletes sustain performance during long competitions, tournaments and events involving repeated bursts of high-intensity activity.
