Before long-distance running, you might as well have a cup of coffee, sports, caffeine drink, running coffee, the benefits of running coffee on exercise.

Caffeine used to be a restricted product for athletes and was thought to cause dehydration. However, new research shows that a caffeinated drink can help people stabilize their protein bodies.

Over the past 400 years, caffeine has become an indispensable part of people's daily lives in the West. For most of us, caffeine that can be naturally extracted from more than 60 plants is the equivalent of refreshing coffee in the morning, or a necessary means of sharpening the senses in the afternoon when you are extremely sleepy. However, in addition to being widely used as a stimulant, caffeine actually hides a variety of sports benefits, so much so that many of the world's leading long-distance runners use it as an important part of pre-race preparation.

"I usually drink some coffee 20 minutes before the game," Mo Fareh, a famous British track and field athlete, revealed in his autobiography double ambition. "when I go on the field, I can clearly feel the power of caffeine." At first glance, it seems foolish for an athlete to drink coffee. After all, it is well known that caffeine causes dehydration and produces a diuretic effect by stimulating urine. In practice, however, this happens only when the human body is at rest, and this function is no longer established during exercise.

"recent studies have shown that the brain is the central governor of fatigue and is responsible for regulating it," said Emma, a senior sports dietitian at Sports Science. "for example, if you do your best at the end of a long-distance run, your brain will detect the increased acidosis in the increase in lactic acid caused by this force, as well as the increased concentration of carbon dioxide in muscle tissue. It will understand that this will affect the stability of your body and will eventually try to slow you down. Caffeine can cover this effect and help maintain the effect of your efforts. "

"if you're going to run for hours, it's a good idea to try a caffeine drip," Emma said. "but we should also keep in mind that caffeine is essentially a stimulant, like many other energy supplements. It's okay to take it once in a while, but it may pay a price for long-term use to take advantage of the benefits it can bring."
