As we all know, life lies in exercise. Exercise has many benefits, but nothing should be overdone, otherwise there will be serious consequences, such as heart problems caused by excessive exercise. What are the symptoms of heart damage caused by excessive exercise?
Symptoms of heart damage caused by excessive exercise 1 Symptoms of heart damage caused by excessive exercise are severe chest pain in the precordial area. Pain can also affect the left shoulder or upper limb, and even lead to finger pain. Other symptoms include chest tightness and palpitation. A few patients are not mainly with heart symptoms, but accompanied by toothache, sore throat, stomach pain and other symptoms.
When sudden myocarditis leads to heart damage, the patient will have symptoms of viral infection at first, such as fever, cough, expectoration, runny nose, abdominal pain and diarrhea. Then there will be chest pain, chest tightness, palpitation, dyspnea and other symptoms, and even cardiogenic shock and syncope in severe cases.
What damage does excessive exercise bring to cardiovascular system?
The benefits of moderate exercise to the cardiovascular system are self-evident. However, in recent years, some data show that excessive exercise may bring adverse effects to the cardiovascular system. These side effects include atrial fibrillation, acute myocardial injury, cardiac remodeling and even sudden death. In addition, excessive exercise may promote coronary artery calcification and aggravate vascular injury.
I. Exercise and Cardiovascular Injury
1, atrial fibrillation: light and moderate physical activity can reduce the incidence of atrial fibrillation, while long-term high-intensity endurance exercise (such as marathon) will increase the risk of new atrial fibrillation.
2. Acute myocardial injury: Long-term large-scale exercise can cause myocardial injury, increase cardiac troponin, and return to normal within 1 week. Common in marathoners and high-intensity military exercises.
3. Heart remodeling: Moderate exercise can promote the adaptive growth of exercise myocardial fibers and corresponding capillaries, and form an athlete's heart, which is a good thing. However, overload exercise can cause psychological remodeling of heart diseases, such as ventricular hypertrophy.
4. Sudden death: Sports sudden death refers to the death that occurs within 6 hours during or immediately after exercise. Studies have confirmed that the high incidence of sudden death of marathon runners is related to the huge amount of exercise.
5. Coronary artery calcification: In recent years, European and American studies believe that high-intensity exercise may promote the occurrence and development of coronary artery calcification.
Second, why is this?
Long-term high-load exercise makes heart rate, blood pressure and myocardial output run at a high level, produces a lot of free radicals, starts oxidative stress, and finally damages myocardial cells.
Third, how to prevent it?
1, exercise preconditioning: refers to short-term and high-intensity intermittent exercise, which leads to myocardial ischemia and hypoxia, thus playing a role in protecting the heart. To put it bluntly, it is an off-site warm-up activity.
2. Low-pressure and low-oxygen intermittent adaptive training: In recent years, the protective effect of low-pressure and low-oxygen adaptive training on cardiovascular system has been paid more and more attention, and it has been gradually applied in the aerospace field.
3. Drugs: At this stage, there is no clear drug that can alleviate exercise-induced myocardial injury. Studies have shown that allicin and rhodiola can resist exercise-induced myocardial injury.
In a word, exercise is not completely beneficial to health, so it is necessary to formulate appropriate exercise intensity. I still think China's traditional golden mean philosophy is reasonable. The doctrine of the mean, everything wins, so does sports.
Symptoms of heart damage caused by excessive exercise 2 nausea and vomiting
Nausea and vomiting after exercise. If it is not caused by diet, it is caused by excessive exercise and lack of oxygen.
Dizziness and headache
If you have dizziness, headache and other symptoms during or after exercise, you should stop exercising and check your cardiopulmonary function. If it happens continuously, it is probably a signal of insufficient blood supply to the brain.
Chest discomfort
At present, sweating in the chest, accompanied by shortness of breath, may be a message that the heart is affected, and exercise should be stopped immediately.
weakness of limbs
If you feel tired after exercise, you can recover after a rest of 15 minutes. If this happens for several days in a row, it may be a sign of spleen damage.
anorexia
Under normal circumstances, Yu Donghou will feel particularly hungry. Because exercise accelerates the metabolism of the body and consumes a lot of energy. If you feel poor appetite and don't want to eat anything after exercise, it means that you have exercised too much.
Key pain
If you suffer from joint pain for more than 30 minutes, you should pay attention to exercise. If the pain occurs at or near the joint and there is joint dysfunction, whether to pull the ligament should be considered.
If the patient has heart discomfort after exercise, it is considered as angina pectoris caused by exercise. Patients are advised to reduce the frequency and time of exercise, such as exercising once a week. No more than 5 times, each time no more than 30 minutes. If the condition is unstable, it is suggested not to exercise in the near future and take a full rest to further clarify the severity of coronary heart disease.
Some patients may have chest tightness, chest pain, palpitation, palpitation and other discomfort symptoms after exercise due to severe coronary artery stenosis, while others may be simple X syndrome or coronary myocardial bridge. These two problems are not very serious and can be treated by improving circulation and adjusting the way of work and rest.
Symptoms of heart damage caused by excessive exercise 3 Excessive exercise may cause the following symptoms:
1, mental depression: The original intention of fitness should be to relieve stress and make body and mind happy, but if mental depression occurs during exercise, you should actively adjust yourself and reduce the amount of exercise.
2, muscle pain: due to the accumulation of lactic acid, muscle pain after exercise is normal, but if the pain lasts for 3-4 days or longer, it is necessary to reduce the intensity of exercise. If it is serious, you should stop exercising immediately and do massage and physical therapy at the same time.
3, headache, dizziness: generally do some strenuous actions, this will happen, which is mainly related to changes in blood pressure and low oxygen content in the blood. It is suggested that people with poor physique choose appropriate exercise according to their own situation.
4, nausea and vomiting: if it is not caused by diet, it is mostly caused by excessive exercise and hypoxia. Exercisers should choose a suitable exercise plan according to their own physiological conditions, starting with a small amount of exercise and step by step.
5. Feeling tired: Physical fatigue after exercise is normal, but if fatigue lasts for 2-3 days or longer, it may be the result of excessive exercise. At this time, it is necessary to temporarily stop exercising and let the body fully recover.
6. Thirst: It is normal to be thirsty after a lot of exercise, but it should be noted that water should be replenished in time before, during and after exercise, especially after exercise, it is best to drink some salty drinks or water.
7. On the night of exercise, the quality of sleep becomes worse, and it is easy to wake up and even insomnia.
8. Feel flustered, short of breath, dizziness, sweating, chills and other obvious discomfort symptoms.
9, the whole body aches, and it is difficult to get up the next day after exercise.
10, listlessness, low work efficiency, loss of appetite, nausea and vomiting.
1 1, lack enthusiasm for fitness, and even don't like sports.
12, resting heart rate and exercise heart rate increased obviously.
13, sudden pain in a certain part of the body, especially in the joints.
