Many people ask Dr. Wang, who advises us to exercise every day, so how to exercise, what exercise, how long to exercise and what matters to pay attention to are good for cardiovascular and cerebrovascular diseases.
In fact, the reason is very simple. Life lies in exercise. Think about the blood flowing in blood vessels. Is it that we sit still and the blood flows fast or that the blood flows fast after exercise? Is it easier to block blood vessels with fast blood flow or slow blood flow? Of course, this is just our thinking, and many problems still depend on objective investigation evidence.
First, a research report was published in the Journal of American Heart Association, and 149,000 people were followed up for nearly 10 years. It was concluded that people who sit for more than 8 hours a day have a 52% increase in death risk compared with those who sit for less than 4 hours, and sedentary people have an 80% increase in all-cause death risk compared with those who exercise! Sedentary people have a 107% higher risk of cardiovascular death than those who exercise! First of all, it is affirmed that no exercise significantly increases the risk of cardiovascular disease.
Second, on January 8, 2018, a study published in Circulation magazine showed that exercise can reverse the harm caused by sedentary heart aging and prevent the occurrence of heart disease. No exercise will cause the heart muscles to become stiff. Be careful that the muscles become stiff, your blood pressure will rise, and the ventricle will not be able to pump blood effectively. The worst case is heart failure.
Third, the United Kingdom conducted a study of 80,000 people, and observed it for 10 years, mainly to explore the relationship between different kinds of physical exercise and all-cause mortality. The research results show that swing sports, including team sports such as tennis and badminton, can reduce the level of all-cause mortality the strongest, which can be reduced by 47%. Swimming can reduce the death rate by 41%. Aerobic exercise, more refers to aerobic gymnastics, which can reduce the mortality rate by 36%. Compared with people who don’t exercise at all, running can only reduce all-cause mortality’s contribution by 13%. However, cycling performed even lower in this respect, only dropping by 10%. (Running and cycling also belong to aerobic exercise) The above research is to reduce all-cause deaths, that is, deaths caused by various reasons, and the mortality rate can be reduced through the above exercises; For reducing the risk of death from cardiovascular diseases, the top three are these three kinds of exercises.
These three studies tell us that the benefits of exercise on cardiovascular diseases, in fact, we have always encouraged aerobic exercise, that is, moderate-intensity sustained exercise, such as swimming, cycling, aerobics, running, playing badminton, etc. These exercises can be adhered to according to their own abilities and needs. 3-5 times a week, each time is not less than 30 minutes, and the heart rate is controlled at 170- one’s age. This heart rate is a relatively simple calculation method, which can be used as a reference. When we exercise, the heart rate is controlled at 170 times MINUS one’s age, so it is not appropriate to be too fast. Generally speaking, our maximum limit is 220 MINUS our age, which is the upper limit of our strenuous exercise, and it is generally not appropriate to exceed this heart rate. However, for the sake of cardiovascular health, moderate-intensity and persistent aerobic exercise is recommended, and strenuous exercise is not recommended.
Research shows that, in terms of the length of time, the best duration of each exercise should be between 45 and 60 minutes, less than 45 minutes, the effect is weakened, more than 60 minutes, there is no higher income, and many will have negative effects, 3-5 days a week, the effect is better.
