Is your heart and lung function good? Long-distance running, swimming, etc. , won't make you pant like an ox and become dejected and despondent; Then, your heart and lung function is better than the average person. According to the survey, having good lung function similar to athletes' long airbags or giant lungs, the mortality rate and the probability of suffering from various long-term diseases such as diabetes, heart disease and hypertension are relatively reduced.

Convert oxygen into energy

Cardiopulmonary function refers to the ability of people to absorb oxygen and convert oxygen into energy. The whole process involves the function of the heart to produce and pump blood, the ability of the lungs to take in oxygen and exchange gas, the efficiency of the blood circulation system to transport oxygen to all parts of the body, and the function of muscles to use this oxygen.

Good cardiopulmonary function also reflects that the main functions of the body can run healthily, so it can be inferred that the probability of suffering from chronic diseases such as cardiovascular diseases, endocrine system diseases and respiratory system diseases is low. Modern people do exercise, in addition to fitness, more to reduce fat and lose weight; In addition, exercising heart and lung function should also be one of the purposes of exercise.

Aerobic exercise can exercise cardiopulmonary function. Generally speaking, moderate exercise that reaches 60% to 70% of the highest heart rate (that is, 220 MINUS a person's age) has the best effect of reducing fat. In exercise, 40% of energy consumption comes from fat and 60% is carbohydrate. If you want to exercise cardiopulmonary function, you need to do strenuous exercise with a maximum heart rate of more than 70%. At this time, the energy consumption is 90% carbohydrate, 10% fat.

For example, obese people need to exercise to lose fat. Although strenuous exercise consumes a lot of calories, it is not suitable for rushing to do too strenuous exercise at first, because their cardiopulmonary function can't cope; Or it is necessary to reduce fat through moderate exercise and improve the basic cardiopulmonary function, and then gradually lose weight, so as to enhance the amount of exercise, exercise cardiopulmonary function and further improve the effect of reducing fat.

Improve cardiopulmonary function

Experts suggest that men over the age of 45 and women over the age of 55 should have a doctor at their side when conducting the maximal oxygen uptake test in case of emergency. In addition to measuring oxygen uptake with instruments, it can also be evaluated by climbing stairs, running back and forth, or running for a specific distance such as 2.5 km or 1 km.

Because people are affected by the changes of fat ratio and exercise amount, the cardiopulmonary function of ordinary people

It will decrease slightly with the increase of age, with males decreasing by 0.46 units a year and females decreasing by 0.54 units. Experts suggest that urbanites should do more moderate exercise and constantly improve the level of cardiopulmonary function in order to maintain physical and mental health.

Long airbags have many advantages.

Blood pressure: Because the heartbeat is more effective, and exercise helps to lower cholesterol and avoid the increase of blood pressure caused by blood vessel blockage, the static blood pressure drops or tends to be normal.
