Patients with heart disease must pay attention to the following problems when participating in sports. 1. Aerobic exercise should be done. All kinds of exercise can improve the condition of patients with heart disease, but moderate aerobic exercise has the best effect. The so-called aerobic exercise refers to the exercise of large muscle groups, such as jogging, swimming, brisk walking, playing Tai Ji Chuan, cycling and so on. These whole-body exercises mainly exercise organs and tissues related to oxygen inhalation (such as heart, lungs and blood vessels). During exercise, strong and accelerated breathing makes the lungs inhale more oxygen for the heart and blood vessels, thus promoting metabolism and accelerating the recovery of coronary artery and myocardial lesions. Moreover, insisting on aerobic metabolic exercise can improve the resilience of the heart and reduce the probability of sudden cardiac death. 2. Pay attention to sports style. Exercise for patients with heart disease should be gradual, moderate in intensity and persistent. Activities should be based on full-body exercise. Move slowly and rhythmically, breathe naturally, relax your muscles, and avoid sudden changes for a long time, such as leaning forward, leaning back, and excessively bowing your head; Don't do strenuous exercise. It is not advisable to choose a vertical posture for exercise. You must exercise in a horizontal posture. In other words, don't stand. Sit and exercise. Change to lying down. Do abdominal exercises. This is because upright movement requires the heart to pump more blood upward, which increases the burden on the heart; Parallel movement smoothly controls the blood at the same level as the heart, thus effectively and effortlessly strengthening the blood circulation of blood vessels around the heart and promoting the repair ability of damaged organs. Patients with heart disease should not do local muscle activities (such as upper limbs or lower limbs) indoors, such as dumbbells, tensioners and parallel bars. Although the local muscle activity is not greater than the whole body activity, it is easy to induce heart disease. Heart disease Patients with heart disease are less likely to have a heart attack when doing general exercise. When local muscles are active, local muscles and blood vessels relax and most inactive muscles and blood vessels contract, but blood pressure rises, which increases the burden on the heart.
