Does running for a long time have an effect on the heart?

The role of running: Running can protect the heart, the heart is an important organ of the human body that is prone to aging, and the normal function of the heart has a direct impact on the function of other internal organs. It is medically believed that the first thing to do is to maintain the function of the heart in order to maintain health.

Middle-aged people are prone to ischemic heart disease, which causes myocardial ischemia due to coronary artery blockage, causing angina pectoris to myocardial infarction. Running exercise can keep the coronary arteries in good blood circulation, long-term running exercise people's coronary arteries will not be narrowed due to age, to ensure that there is enough blood supply to the heart muscle, so as to prevent various heart diseases, maintain good heart function. Running is a full-body exercise that accelerates blood circulation, adjusts blood distribution throughout the body, and eliminates congestion.

Through the movement of the lower limbs, the human body is pushed forward at the same time, and the venous blood is effectively driven back to the heart, reducing the venous and pelvic congestion of the lower limbs, and preventing intravenous thrombosis. Running can regulate the excitation and inhibition of the cerebral cortex, improve the function of the nervous system, eliminate the fatigue of mental work, and prevent neurasthenia.

Running is a form of exercise. Daily exercise, no matter what form you use, should be moderate, that is to say, to achieve a state of nourishing exercise. Too much exercise is non-nourishing exercise, and non-trophic exercise is not good for the body, including the heart.

You can run, and whether you can run depends on your physical condition

1. Pain after running.

After each run, it is easy to experience pain in the knee joint or adjacent parts or discomfort of the lesion, which is a sign of physical injury or overwork.

2. People who have had related surgeries.

Patients who have undergone knee or hip replacement surgery are not suitable for prosthetic life extensions.

3. Excessive obesity.

Patients with BMI (body mass index) greater than 30 are not suitable for the time being, because excessive weight will increase the wear and tear of the joints of the lower limbs, such as obese people are very prone to knee osteoarthritis.

4. Abnormal range of motion of the joint.

For example, insufficient hip extension, knee hyperextension, ankle dorsiflexion, etc.

5. Suffering from certain diseases.

People with diseases that are not suitable for running, severe heart disease, renal insufficiency, etc., are not suitable for running.

When muscles are exercised, substance metabolism increases significantly. The adaptive change of the circulatory system is to increase cardiac output to increase blood ** and speed up the delivery of substances, so as to meet the needs of muscle tissue to consume oxygen and nutrients, and take away excessive metabolic waste in time, otherwise muscle exercise cannot be sustained.

Regular physical exercise or exercise training can promote the good adaptation of the morphology, function and regulation of the human cardiovascular system, which can be summarized in the following aspects:

Sinus bradycardia.

Exercise training, especially endurance training such as long-distance running, can slow your heart rate at rest. Elite endurance athletes can have a resting heart rate as low as less than 50 beats per minute, a phenomenon called sinus bradycardia. On the one hand, this is the result of the increased action of the vagus nerve that controls the activity of the heart and the weakening of the sympathetic nerve (the nerve that mobilizes the movement of the body and increases the heart rate); On the other hand, increased cardiac volume and myocardial enhancement (highlighted below) have a marked increase in stroke volume at rest.

The number of beats per minute decreases, indicating that the heart is in a good state of energy conservation at rest. Sinus bradycardia is a good response to improved heart function after long-term training and can increase the reserve space for heart rate (the potential for heart rate to increase). When exercising, the heart rate increases, up to 180-200 beats, close to the maximum heart rate, so that the heart reserve is fully mobilized.

Enlarged heart. Long-term training can make adaptive changes in the morphological structure and physiological function of the human heart. The most obvious is myocardial hypertrophy, but exercise-induced cardiomegaly is fundamentally different from pathological cardiomegaly. The former has a well-developed myocardium, strong myocardial contractility, and high cardiac reserve, usually weighing no more than 500 grams.

Pathological cardiac hypertrophy is often abnormally enlarged but accompanied by heart failure, such as pulmonary hypertension caused by increased vascular resistance in the lungs, and the right ventricle is often particularly hypertrophied.

Improvement of cardiovascular function.

As a unique high-function, high-reserve, and large heart of athletes, the "athlete's heart" plays a very important role in competitive sports.

The functional changes of the "athlete's heart" are mainly manifested in:

1. Increased mental reserve.

It is important to note here that there is not much difference in cardiac output per minute at rest in long-term trainers compared to the general population, except that long-term trainers have a larger stroke volume and a lower heart rate.

2. Enhance myocardial oxygen supply.

Long-term endurance training can improve the function of the coronary arteries by increasing the diameter of their vessels, increasing the elasticity of their walls, decreasing lipid deposition, decreasing resistance, and can increase collateral circulation in the coronary arteries.

3. Reduce the oxygen consumption rate of myocardial work and increase myocardial stability.

Endurance training can reduce catecholamine levels and lower systolic and diastolic blood pressure at rest.

4. Surrounding effects.

Mainly systemic changes other than the heart. Enhancement of skeletal muscle function, including increased aerobic metabolism of skeletal muscle, increased actin and muscle glycogen; An increase in the number of capillaries in the muscles, an increase in vasodilation, a decrease in fat deposits in the blood vessel wall, and a decrease in resistance all reduce the workload on the heart.

What changes does long-term exercise bring to the heart?

Proper exercise will increase the body's ability to resist disease, so proper running will not be bad for the heart. However, you must be careful not to run long-distance running, or excessive long-distance running, which may cause damage to your body. In fact, long-distance running not only exercises your physical health, but also allows you to develop a good habit of sticking to one thing, and exercise a strong will and firm character.

For those who have just started to learn to run, we must pay attention to a few points to protect themselves, so as not to cause unnecessary physical wear and tear caused by improper exercise.

1. Be sure to warm up before running. For people who have just started to learn to run, they only know that they want to run, and some of the preparatory work is easy to ignore, but this is an indispensable part of the entire later exercise.

2. Posture during running is also very importantIn fact, I didn't pay attention to this, in a run with a friend, he ran with the running software, the software will keep reminding him of the running posture problem, in the whole process, you will find that running is easier than before, and very light, only to know the importance of posture during running.

3. After running, many friends just rest directly, in fact, after running, do a stretch again, which will make your body recover faster. After running, you may have muscle soreness and trembling legs, which are normal body reactions, and in order to alleviate this situation, you can do more stretching exercises. Generally, the ankles and wrists are retreated, the hips, waist and shoulders, and the back arms, these places, serious stretching, will make you relax physically and mentally.

The charm of running is very great, I hope you can also take care of your body when running, properly replenish water, salt, sugar, vitamins and other energy after long-distance running, after all, running is hard, strengthen the exercise with a healthy and reasonable diet to get twice the result with half the effort.

The most direct injuries of high-intensity exercise are muscle strains and fractures, while heart disease is slowly planted day after day.

Exercise is good for the heart, but it is very important to master the way or method of exercise, as well as the intensity of exercise.

The method of running is very important, do a good job of moving your body before running, and run gradually rather than running far at once. People who love to run are not in bad health. Or something went wrong.

It is nonsense that the amount and intensity of ordinary people's exercise cannot cause damage to the heart at all, provided that it is done gradually, scientifically running, and perseverance, and the heart function will be stronger.

I'm worried that I'm going to lose my heart, and now I have a heart rate of 170 to 180 at a pace of more than 5 minutes, and it's been two years, and I'm not sure if I can be resolute until 10 years?

Everything needs to pay attention to a quantity, to see if your body can bear it, a moderate amount of exercise is actually good for the heart.

The original intention of practicing long-distance running is to be healthy, but there are also people who practice and see that they have a sense of comparison and competition, regardless of their own conditions, blindly chasing speed and seeking miles, which deviates from the original purpose and causes self-injury.

It is advisable to lower the pace again, and use the heart rate as the standard for pace, your pace is significantly faster. My heart rate is generally controlled below 130 and above 135 absolutely stops. Walk.

The running time is controlled to about an hour. Running down, the heart is not uncomfortable, it is very comfortable.

A small amount of exercise is good for the body, but more exercise is definitely not good, otherwise athletes should be the people who live the longest in the world.

Low heart rate, enlarged ventricles, irregular heart rate, and atrioventricular block are all the result of high-intensity long-distance running.

You've been running for so long, and you're even running while sleeping, eating, excreting, and drinking, how can you not run your heart [manual funny].

Long-distance running may cause damage to your body, so be aware of this. Proper exercise is best.

As long as you don't have underlying diseases, jogging regularly will only make your heart stronger!

All exercise is good or bad for the body, and a moderate amount of exercise is good for the body.

Not good. Certainly, excessive exercise is harmful and unhelpful.

Of course, exercise is good for the heart, but everything should be done in moderation and not in excess.

The only way to run the heart is to run too hard and too high.

Twenty years of running, sinus bradyarrhythmia, resting heart rate 45 beats.

Long-distance running has great benefits for cardio and lung function!

Even if you run away, you still have to run tomorrow. Run up and walk together!

It's my own opinion that I don't love sports!

Increased weight! Not good. Leisure sports as well.

It's a question of fitting or not.

Jogging, isn't running so fast looking for death?

What do I need to do before and after exercise?
