Because he stands at 6’5″, Usain Bolt must produce more power than his competitors to compensate for drag on his large frame. A recent study, published in the European Journal of Physics, found that with each stride, Bolt produces nearly twice the power output of a Tour de France cyclist in the closing stages of a sprint—or the same amount of force as a knockout punch from a heavyweight boxer.

To reach superhuman speeds, the fastest man on earth needs energy—real energy—in the form of carbohydrates prior to a race. Learn more about how Bolt fuels up before a race at STACK.com.
