As if you needed another reason to hate the gym, it now turns out that exercise can exhaust not only your muscles, but also your eyes. Fear not, however, for coffee can perk them right up again. Duringvigorousexercise, our muscles tire as they run out of fuel and build up waste products. Muscle performance can also be affected by aphenomenoncalled 「central fatigue,」 in which an imbalance in the body』s chemical messengers prevents the central nervous system from directing muscle movementseffectively. It was not known, however, whether central fatigue might also affect motor systems not directlyinvolvedin the exercise itself—such as those that move the eyes. To find out, researchers gave 11 volunteers a carbohydratesolutioneither with a moderate dose of caffeine—which is known to stimulate the central nervous system—or as a placebo without, during 3 hours ofcycling. After exercising, the scientists tested the cyclists with eye-tracking cameras to see how well their brains could stillcontroltheir visual system. The team found that exercise reduced the speed of rapid eye movements by about 8%,preventingtheir ability to capture new visual information. The caffeine—the equivalent of two strong cups of coffee—wassufficientto counteract this effect, with some cyclists even displayingincreasedeye movement speeds, the team reports today in Scientific Reports. So it might be a good idea to get someone else to drive you home after that marathon.
