Is coffee a stimulant for athletes?
Coffee is not a stimulant for athletes.

Coffee contains caffeine, and whether it reacts to caffeine varies from person to person. For example, some people are allergic to pollen, while others are not suitable for eating seafood. And these two situations will not have any impact on most people.

As for how much coffee to drink every day, in some coffee-consuming countries, the average person should consume about 250-600 mg of caffeine every day. After repeated scientific research and analysis, this dose has no side effects on human body. Therefore, it is not too much to drink no more than 4 cups of Starbucks coffee every day.

Introduction.

Caffeine can accelerate heart rate, enhance myocardial contraction, and raise blood pressure. And it may also increase the level of cholesterol in the blood, so many people worry that drinking coffee for a long time will increase the prevalence of cardiovascular diseases.

As early as 1970s and 1980s, there were many papers demonstrating that drinking coffee in large quantities for a long time would lead to the risk of myocardial infarction, leading to premature beats and arrhythmia. But later studies found that these studies did not consider the influence of life factors, because people who drink a lot of coffee for a long time are often office workers who are tired from work, sedentary in the office, irregular in work and rest, unhealthy in diet, seldom exercise and addicted to alcohol and tobacco.
