Effective ways to increase lung capacity include chest expansion exercises, aerobic exercises, swimming or diving. 1. You can practice chest expansion exercises, arm lifting and other hand exercises to exercise the thorax and chest breathing dynamics. 2. Increase aerobic exercise, do some long time jogging or fast walking and other sports, can gradually exercise to increase lung capacity. 3. Participate in diving, swimming and other sports, practicing in the water need to overcome the resistance of the water and adjust the breathing rhythm, etc., can gradually enhance lung capacity. In addition, often participate in soccer, basketball and other sports, make a long and reasonable training program, and adhere to the implementation, can gradually increase lung capacity. Exercise can enhance the strength of the respiratory apparatus, improve the utilization rate of alveolar gas exchange, improve the efficiency of each breath, and effectively improve lung capacity. However, it should be carried out reasonably under the guidance of professionals.
