Endurance exercise leaves can delay the deterioration of respiratory muscle function (maximum oxygen uptake), improve physical strength, improve the patient's exhalation process, increase the range of muscle activity in fascia room, increase the gas flow blocking airway, fully exhale alveolar residual gas, and effectively improve lung ventilation. Physical exercise can also increase the discharge of respiratory secretions, reduce the chance of infection, relieve bronchial inflammation and cough symptoms, maintain respiratory muscle strength and increase lung ventilation. In addition, physical exercise can increase patients' immunity, improve systemic metabolism, improve cardiopulmonary function and enhance oxygen absorption ability, thus alleviating asthma and shortness of breath symptoms. The specific methods of physical exercise for patients with chronic obstructive respiratory disease are as follows:
(1) endurance exercise
When patients with chronic obstructive respiratory disease begin to exercise, moderate or low intensity exercise is appropriate, and the initial exercise time should not be too long. With the improvement of functional level, symptoms are alleviated, and exercise time can be gradually extended. The recommended forms of exercise are walking, stationary cycling, mountain climbing, etc.
(2) Respiratory muscle exercises
The patient first performs abdominal breathing exercises. The patient takes a quiet and comfortable posture, eliminates distractions and relaxes the whole body. Exhale first, then inhale to practice. When exhaling, press the upper abdomen with one hand, the intra-abdominal pressure increases, the diaphragm rises, and the abdomen sinks. When inhaling, the upper abdomen rises slowly and the diaphragm drops. Take a deep breath consciously. After inhaling, you can pause for a moment and then exhale slowly. Be careful not to use force when exhaling. On the basis of practicing abdominal breathing, carry out special breathing.
Muscle exercise can also be combined with activities such as self-massage and walking. Pay attention to exercise; People with acute cold symptoms and cardiopulmonary insufficiency should not be satin-trained. When you start abdominal breathing, you should be too slow and too deep. A practice time should not be too long. Generally, you can rest after 5-6 exercises. If you have dizziness, headache, chest tightness and other symptoms, you should stop practicing.
(3) upper limb resistance training method
In the rehabilitation exercise of chronic obstructive respiratory disease, the upper limb resistance training method is adopted, and the training is mainly repetitive low resistance exercise. General weight 1-2 kg, patients are required to exhale while exerting maximum force.
