Peritoneal dialysis patients need to choose appropriate exercise methods to avoid exercise misunderstandings due to limited physical fitness.
Exercise is divided into aerobic exercise and anaerobic exercise. Anaerobic exercise is an exercise that causes local muscle tension, such as weightlifting. Aerobic exercise can help improve cardiopulmonary function and speed up metabolism. It is a recommended form of exercise.
Aerobic exercise suitable for peritoneal dialysis patients includes walking, walking, stair climbing, mountain climbing, cycling, rowing, skiing, Waidan Gong, Tai Chi, square dancing and non-jumping aerobic dancing (such as Rhythmic gymnastics).
Rugby, soccer, boxing, fighting, sit-ups and other sports. Abdominal thrusts or rapid increases in abdominal pressure should be avoided.
Exercise frequency
The recommended exercise frequency is 3-5 times a week. Exercises with small range of motion, such as walking, brisk walking, Tai Chi, etc. Peritoneal dialysis fluid can be routinely retained in the abdominal cavity. Exercises with a large range of motion, such as mountain climbing, aerobic exercise, etc., can empty the abdominal cavity and reduce abdominal pressure and burden (long-term dialysis patients can retain a small amount of fluid in the abdominal cavity, which can lubricate and prevent abdominal pain during exercise) .
Each exercise is divided into three time periods: warm-up period (5-10 minutes), duration period (about 30 minutes), and recovery period (5-10 minutes). Warming up before exercise is very important, as it can increase the body's flexibility and reduce sports injuries. Each exercise should last 30 minutes to achieve the effect of exercise. After exercising, stop slowly. Stopping quickly can cause hypotension and myocardial hypoxia. At the same time, exercise must be sustained. Exercising for 30 minutes three times a week is more effective than exercising for 2 hours once a week.
Exercise intensity
Exercise intensity should be within a somewhat tiring but acceptable range. Chatting with others while exercising means exercising at a moderate intensity. Generally, the heart rate of patients without heart disease should reach 70-85% of the maximum heart rate during exercise. At present, the most widely used and easiest to calculate are:
Optimum exercise heart rate range = (220-age) (70-85).
For patients with simple uremia, we recommend 70 as the highest parameter. For patients with heart disease, systolic blood pressure is slightly elevated after exercise (the increase in systolic blood pressure does not exceed 20mmHg) and heart rate is elevated (the ratio of post-exercise heart rate to pre-exercise heart rate does not exceed 20 beats/minute or the maximum heart rate during exercise does not exceed 120 times/minute) is a normal reaction. However, it is not advisable if shortness of breath, angina, irregular heartbeat, dizziness, nausea, pale complexion, long-term fatigue, and insomnia occur after activity. It is recommended that this exercise is excessive and that the next exercise should be reduced or suspended.
Other preventive measures include: Avoiding exercise on an empty stomach and immediately after meals. If you are feeling unwell, have poor blood sugar control, or are in poor dialysis status, do not force yourself to exercise. If you feel dizzy, wheezing, obvious heartbeat, cold sweat, pale complexion, nausea, chest tightness, chest pain, fatigue, etc. During exercise, you should stop and rest immediately. If necessary, seek medical attention as soon as possible. It is recommended to exercise and take walks with family or friends, so as not to increase the number of patients.
