Reminder: don't drink coffee before exercise
Researchers at the Center for Human Physiology at the University of Zurich Hospital in Switzerland have found that drinking coffee before exercise may have an adverse effect on the heart because caffeine intake before exercise limits blood flow to the heart muscle during exercise.
The researchers studied 18 healthy young people and found that caffeine did not affect myocardial blood flow when not exercising, but exercise immediately after taking caffeine tablets reduced myocardial blood flow by 22% at normal pressure. The reason is that caffeine blocks specific receptors in the walls of blood vessels, which may hinder the transmission of dilated vascular signals, thereby reducing myocardial blood flow and affecting oxygenation in the body.
Coffee has an exciting effect on the brain and used to be used by some athletes as a stimulant before the competition, but its main function is to speed up the heartbeat and can not guarantee the energy supply of the body in the early stage of exercise.
Studies have shown that eating carbohydrates before exercise can help increase the amount of glucose in the blood, thus stimulating the body's function and helping to increase the intensity of exercise.
