What happens when you exercise your heart often? Fitness exercise has attracted the attention of many of us. There are actually many ways to keep fit, and the gym is also a place that many people like to go. Let's know what it's like to exercise your heart regularly.
What happens when you exercise your heart often? 1 The effect of long-term exercise on heart function is that it can effectively enhance myocardial contractility and enhance one's physical fitness. During exercise, the whole body blood circulation is accelerated, and the heartbeat is accelerated. Proper exercise is good for the heart, such as jogging, playing Tai Ji Chuan, swimming and other aerobic exercises. But don't do strenuous exercise. After strenuous exercise, the heart will beat too fast and even affect the heart function. Especially people with basic heart disease will have shortness of breath and difficulty breathing. Need to reduce the intensity of exercise to avoid being injured again.
Is exercise good for the heart?
Exercise is good for the heart, but you must exercise moderately. Too little exercise Otawa is bad for the heart. In the process of exercise, especially in the state of slight sweating, it will effectively improve the sports ability of the human body and improve the reserve function of the human heart.
The normal heart does not need 100% work in the calm process, but only a part of myocardial cells. During exercise, the cardiac myocytes of the heart will be mobilized, and the exercise ability will naturally improve. If the heart has no other reserve function during exercise, patients will have cardiac insufficiency, such as dyspnea, breathlessness and fatigue.
Therefore, regular exercise can exercise the heart reserve function of human heart. During exercise, the heart reserve function will be exercised, and it will be greatly displayed when the heart is affected by other things in the future.
What are the consequences of excessive exercise on the heart?
If you are a heart patient, you should remember that you should choose brisk walking or jogging when exercising, and don't overdo it by doing strenuous activities.
The results of a study show that excessive exercise increases the risk of death from cardiovascular disease in patients with heart disease. In this experiment, 2400 patients with heart disease were followed up, and the relationship between exercise and cardiovascular mortality was studied. The results show that under the same physical exertion, people's cardiovascular health promotion is the same whether walking or running.
"However, this study found that patients with heart disease who run about 48 kilometers and walk about 73 kilometers a week have a mortality rate of 65% due to cardiovascular diseases." Paul williams of the Life Sciences Department of Lawrence Berkeley National Laboratory said.
This experiment shows that the benefits of walking and running to human health will not accumulate continuously. To some extent, exercising 48 kilometers per week increases the risk of cardiovascular disease. In addition, competitive sports will also increase the risk of acute diseases.
Paul pointed out that for patients with heart disease, doctors encourage them to take part in exercise, but they should also pay attention to the degree of exercise. Generally, 30 to 40 minutes a day is enough. Excessive exercise is harmful to your health. This article was published in Mayo Clinical Progress. At the same time, a Spanish researcher also pointed out in the report that from the perspective of health alone, people don't have to exercise excessively, and it is enough to ensure that the exercise time does not exceed 60 minutes every day.
Exercise is good for both body and mind. Many studies have shown that moderate and regular exercise, such as brisk walking or jogging, is helpful to lose weight, regulate mood changes, help cardiovascular diseases, and even reduce the risk of death from diseases such as hypertension, stroke and type 2 diabetes. At present, American sports activity guidelines suggest that 150 minutes of moderate-intensity exercise or 75 minutes of high-intensity exercise should be carried out every week to maintain the best health. But does excessive exercise have any effect?
According to a new study published in the Mayo Clinic Bulletin, the answer is yes. The results show that there is a clear link between cardiovascular death and excessive exercise for survivors of heart attack.
The consequences of excessive exercise on the heart are more serious, so when we exercise, we must exercise on the basis of our own physical fitness, and do not exceed the range that the body can bear, otherwise the body will have some unexpected diseases, because the diseases caused by excessive exercise are the last thing we can accept.
What happens when you exercise your heart often? 2 The benefits of regular exercise on heart rate.
What is the correct heart rate during exercise?
Because everyone's health and physical condition are different, the aerobic heart rate range of fitness exercise should also vary from person to person and from time to time. The following methods to determine the aerobic heart rate range can be used for reference:
1, a healthy person
Aerobic heart rate can be controlled at 120 ~ 180 beats/min, and can be subdivided into light exercise 120 ~ 140 beats/min and moderate exercise141~.
2. If you want to personalize, you can use common formulas to calculate.
Reasonable heart rate in aerobic exercise = (maximum heart rate-quiet heart rate-age) ×Q+ quiet heart rate. Maximum heart rate in formula ≈ 2 10; Quiet heart rate refers to the heart rate in a relatively quiet state before exercise; Q stands for the amount of exercise, less than 50% is a small amount of exercise, 50% ~ 75% is a moderate amount of exercise, and more than 75% is a large amount of exercise.
If someone is 50 years old with a quiet heart rate of 76 beats/min and wants to do aerobic exercise with a small amount of exercise, determine the aerobic heart rate = (210-76-50) × 50%+76 =118 beats/min.
For middle-aged and elderly people, the simplest and safest method can be adopted.
Suitable aerobic exercise heart rate = 170- age. If you are 60 years old, when you take part in aerobic exercise, your heart rate should be controlled at170-60 =110 times per minute. For frail and elderly people, (170- age) ×0.9 can be selected for safety.
It is worth noting that the above content is only a general rule, and it must be applied flexibly according to the specific situation in implementation. Health status, environment, season and mood in different periods will have certain influence on the choice of exercise amount. At this time, the intensity and time of exercise should be reduced accordingly, and the heart rate index should be reduced accordingly to ensure safety.
What happens when you exercise your heart often? Can you lose weight by exercising regularly and sweating?
How to exercise to lose weight is the most effective? Many people think that the more you sweat during exercise, the better the exercise effect. In fact, it is unscientific to lose weight through exercise and sweating. In fact, a lot of sweating will take away potassium ions, sodium ions, salts and other substances in the human body.

Can summer exercise and sweating effectively reduce weight?
It is understood that there are about 3 million sweat glands in the human body, one of which is the secretory part, which has the function of secreting sweat; The other end is the excretory part, which is directly opened on the skin surface and is called sweat hole. The discharge of sweat has the function of regulating body temperature, and also discharges some metabolic wastes.
Under normal circumstances, sweating is a reflex activity, and the secretion of sweat glands can be caused by warm stimulation or mental stress. When heat causes blood vessels to dilate, water in blood transfers heat to the skin surface, and then evaporates with sweat to transfer heat to the surrounding environment. In the high temperature environment, the daily sweat output of human body can be as high as 8- 12 liters.
