You can improve your cardiorespiratory function through aerobic exercise such as jogging, jumping rope, swimming, etc., and you should combine your own situation to choose the exercise that suits you. 1. Jogging: Jogging is an aerobic exercise, can enhance respiratory function, improve ventilation and ventilation, increase lung capacity, increase myocardial contractility, promote body metabolism, jogging should follow a gradual approach, rhythmic jogging, speed should not be too fast. 2. Rope skipping: rope skipping belongs to aerobic exercise, is the first choice to improve cardiorespiratory function, rope skipping can increase the respiratory muscle strength, improve lung capacity, promote the body’s blood reflux, improve cardiorespiratory function. 3. Swimming: the swimming process needs to use the lungs to adjust the breathing, so swimming can improve the utilization rate of the alveoli and blood circulation, can increase the respiratory muscle strength, so that the lung capacity increased, swimming can make the cardiac muscle contraction powerful, blood vessel elasticity increased, effectively improve cardiopulmonary function. There are many ways to improve cardiorespiratory function, specifically according to their own situation, choose the one that suits them. In the process of any discomfort, it is recommended to go to the hospital in time for treatment.
