Aerobic exercise usually chooses exercises with low intensity, long duration and rich rhythm, such as jogging, swimming, cycling, rope skipping, aerobics, brisk walking, etc. For respiratory system patients, exercise can enhance the muscle strength and intensity of respiratory muscles, improve lung compliance, enhance lung function and local resistance of the lung, etc. As for the cardiovascular system, patients can make the heart beat more strongly and regularly through exercise to ensure the efficiency of the heart, thus increasing the function of the heart and reducing the onset of cardiovascular disease. In short, aerobic exercise can make the heart and lungs get sufficient exercise, which is conducive to improving cardiopulmonary function, thus maintaining the best functional state of the whole body tissues and organs, and the body’s resistance is also enhanced at the same time.
