Caffeine, also known as caffeine, is a nitrogen-containing alkaloid. It is mainly found in the fruits and leaves of coffee, tea and Guanana, while cocoa, cola and tea holly also contain a small amount of caffeine.

Caffeine is water-soluble and does not remain in the body. It is completely absorbed by the stomach and small intestine within 45 minutes after ingestion, and then slowly excreted. Most of caffeine is metabolized in the liver, but after drinking coffee, caffeine is distributed in all organs of the body and stays in the body for 6-14 hours. (so it is recommended to drink coffee 30-45 minutes before exercise)

Some experiments have shown that caffeine can accelerate blood circulation. In one experiment, researchers asked two volunteers to drink 150 grams of normal coffee and a second volunteer to drink 150 grams of decaffeinated coffee. Their blood flow velocity was then monitored and found that the blood flow rate of the first volunteer was 26% higher than that of the other. The increase of blood flow rate directly increases the oxygen supply to muscles. For fitness workers, this means that if they drink the right amount of coffee, their muscles can grow and repair better after training.

Japanese researchers asked subjects to drink five ounces of coffee, either regular or decaffeinated, and then measured their fingertip blood flow velocity.

The results showed that within 75 minutes of drinking coffee, people who drank normal coffee had a 30% increase in blood flow speed than those who drank decaf coffee. This is important for fitness people because an increase in blood flow speed increases the oxygen supply to the muscles.
