What are the effects of excessive exercise on heart health?

Everyone knows that exercise is good for physical and mental health. For some patients with heart disease, exercise can benefit the heart a lot. But Confucius once said, "too much", and the same is true of excessive exercise.

If you try to get a healthy effect, the results may backfire. A new study in the United States found that for people with a bad heart, especially those who have had a heart attack, exercising too much is not good for the heart.

The researchers said they studied about 2,400 heart disease survivors who exercised actively and found that the more they exercised, the lower the risk of dying from cardiovascular disease, but only if they didn't overdo it. People who run for exercise have a higher risk of death if they run more than 48 kilometers per week; And for those who exercise on foot, the turning point is 75 kilometers.

This result shows that the effect of running or walking is not infinitely better. Above a certain level, perhaps 48 kilometers per week for running, a significant increase in the risk of death will be seen.

However, the researchers also noted that because the study analysed all heart disease survivors, the results may not be fully generalizable to all populations.

Almost all people with heart disease should exercise, and the average daily exercise time should be 30 to 40 minutes. From a health point of view, (people with heart disease) should not exercise for a longer period of time, especially not more than 60 minutes.

From this point of view, exercise is not for everyone. But if you keep your workout within a reasonable amount, the impact on your body will be positive.

1. Atrial fibrillation: mild to moderate physical activity can reduce the incidence of atrial fibrillation, while excessive high-intensity endurance exercise (such as marathon) for too long can increase the risk of new atrial fibrillation.

2. Acute myocardial injury: anaerobic exercise can cause myocardial injury and cause an increase in myocardial marker troponin, which will return to normal within 1 week. It is more common in the course of marathon runners and high-intensity military exercises.

3. Cardiac remodeling: Moderate exercise can promote the adaptive growth of myocardial fibers and corresponding capillaries in exercise and form an athlete's heart, which is a good thing. However, excessive exercise can cause heart disease to reshape rationally, such as ventricular hypertrophy and so on.

4. Sudden death: Sudden death due to exercise refers to the death of symptoms that occur within 6 hours during or immediately after exercise. Studies have confirmed that the high incidence of sudden death in marathon runners is related to their high amount of exercise.

5. Coronary artery calcification: In recent years, studies in Europe and the United States have suggested that large-scale exercise may promote the occurrence and development of coronary artery calcification. ‍‍

Physical activity strengthens the cardiovascular system.

Running will give you a strong heart and cardiovascular system. While increasing the maximum oxygen uptake, the amount of oxygen delivered to the various organs of the body is greatly increased, and the quality of work of each organ is naturally greatly improved.

In addition, middle-distance running will speed up blood circulation, so that the coronary arteries have enough blood to supply the heart muscle, thus preventing various heart diseases. Through the movement of the lower limbs, venous blood flow back to the heart is promoted and intravenous thrombosis is prevented.

With a strong cardiovascular system, runners' blood quality is better than normal, and the body's adaptation to long-term middle-distance running can improve metabolism and reduce blood lipid and cholesterol levels.

1. Physical exercise can improve cardiopulmonary function and endurance, mainly in reducing the heart rhythm when exercising at rest and under the same load, improving lung capacity can reduce the risk of cardiovascular diseases and cardiac emergencies, and can also reduce its severity if cardiac emergencies occur.

2. Physical exercise can increase the number of capillaries, improve peripheral circulation, reduce hypertension when quiet, significantly increase the fluctuation of the heart, improve coronary artery circulation, and reduce the risk factors of atherosclerosis.

3. Physical exercise can greatly exceed the quantity and quality of red blood cells in the blood, and can also control the levels of blood lipids, cholesterol and blood sugar in the blood.

In our lives, many people pay great attention to physical health, and will choose to enhance the body's resistance and immunity through some physical exercises in their daily lives, but for people with bad hearts, when exercising, we must pay attention to avoid improper exercise methods to make heart disease**, so that the body is harmed to a certain extent. First of all, we can understand that people with a bad heart, once strenuous exercise will cause the heart to beat faster, the blood in the body can not supply blood to the heart in time, and in severe cases, myocardial infarction will occur, which will also bring a certain threat to the life of the human body. In fact, according to scientific research, appropriate exercise methods for patients with heart disease can effectively prevent heart failure, and can also have a certain health care effect on the heart.

Many patients with heart disease want to protect their blood vessels through proper exercise, so that their hearts can become healthier. However, there are many problems that need to be paid attention to in terms of exercise with heart disease, first of all, we must pay attention to the time of exercise, and avoid long-term exercise that causes the body to overwork and increase the heartbeat, which will have a certain impact on the heart, which will also cause heart disease**, which is very harmful to the body. You can exercise appropriately in your daily life, you can choose to exercise for half an hour, rest for a while, and then exercise when the heart beats smoothly.

When exercising, we must choose the right way to exercise, because the heart of heart patients is more fragile, and a certain warm-up exercise can be carried out before exercise, so that the heart can have a transition process and avoid sudden strenuous exercise causing harm to the heart.

Through the above introduction, we can understand that for heart disease patients when choosing exercise, they must pay attention to the method and time, so that they can achieve effective exercise, promote blood circulation in the body, and will also have certain benefits for the heart.

1. Try to avoid strenuous exercise, if the exercise may be vigorous, the heart is prone to insufficient blood supply, easy to faint or palpitations.

2. Learn to walk, walking is a good way to exercise, and it will not cause excessive burden on the heart.

If people with a bad heart exercise, pay attention to moving their muscles and bones before exercising, and don't do too intense exercise if your heart is not good.
