In tests, the researchers found that the heart rate of those who had taken caffeine took about an hour to return to normal, which is twice as long as when they had not had the substance in their body
. "post-exercise, when it is slower, there is an increase in the probability of a cardiovascular problem ular. By studying physically active young adults, we imagined that caffeine would not have an overload effect on the heart during exercise. However, we feared that this would happen in this population, "says Vitor Engraccia Valenti, coordinator of the Unesp Studies Center
This is due to the stimulating power of caffeine, which increases the concentration of catecholamines in the body. blood and can lead to overload in the heart, causing a heart attack.
] "The most vulnerable people are those at risk group and we ask the following question: And in people who have reduced physical preparation, worse?", said the coordinator.
The result of the research removed volunteer participants and left the alert to physical activity practitioners, especially those with hypertension and diabetes.
