August 8 every year is China’s “National Fitness Day”. Since 2009, the “National Fitness Day” was approved by the State Council to commemorate the success of the Beijing Olympic Games, and to advocate universal participation in sports and physical fitness. Life is about sports! Scientific exercise can make us have a good shape and maintain the ideal weight; it can improve our cardiopulmonary function and maintain the ideal physical strength; it can regulate our emotions and make us have a better life experience; it can also make us easier to have a balanced nutrition, a strong body, and a better immunity and resistance to diseases; therefore, exercise is very beneficial for us to obtain physical and mental health. Modern medicine also confirms that “exercise therapy” plays an important role in the prevention and treatment of chronic diseases, and patients who adhere to the “exercise prescription” under the guidance of doctors and nurses can reduce the risk of hypertension, diabetes, hyperlipidemia, hyperuricemia, coronary heart disease and other chronic The risk of chronic medical diseases such as hypertension, diabetes, hyperlipidemia, hyperuricemia, coronary heart disease, etc. can be reduced and helped to control the disease. Chronic kidney disease (CKD) is a common chronic medical disease with a prevalence of 10.8% in China. Today, nephrologists will talk to kidney patients about the correct way to open physical exercise for kidney patients. Can exercise damage the kidneys? Modern research has found that unscientific, high-intensity exercise can cause kidney damage. A large amount of sweating, hyperthermia and dehydration after strenuous exercise can cause a decrease in effective circulating blood volume, causing blood redistribution, resulting in a sharp drop in renal blood flow, which can eventually cause renal ischemia and hypoxia and form abnormalities in the kidney structure. Rest or rehydration to restore renal perfusion, then there will be renal “reperfusion injury”. “Exercise acute kidney injury” can be manifested as hematuria, proteinuria, electrolyte disturbances, rhabdomyolysis, and even acute renal failure. In most cases, these changes can be recovered in 1-3 days and do not develop into serious lesions. However, if you spend a long time in a hot climate with high-intensity sports training, such as athletes and high-intensity military trainers, their kidney injury incidence will increase, and in severe cases can appear “heat stroke”, resulting in systemic multi-organ failure. In addition, contact sports such as boxing and rugby have the risk of direct damage to the urinary tract and are more likely to develop “sports hematuria”. Why do patients with kidney disease need to exercise? Patients with chronic kidney disease (CKD) often complain of easy fatigue, weakness, shortness of breath, joint and muscle pain, lack of energy and interest in activities and work, depressed mood, and lack of quality of life. CKD patients suffer from long-term pain, and as the disease progresses, complications such as renal anemia, renal bone disease, microinflammatory state, malnutrition, and cardiopulmonary decompensation can occur, all of which can lead to reduced skeletal muscle strength and decreased physical activity. patients to further reduce the range of social activities. It was found that patients with pre-dialysis CKD stages 2-5 have significantly low activity and functional decline, and low activity aggravates muscle atrophy, muscle strength loss, functional disability and cardiovascular function decline, which seriously affects the quality of life and prognosis of CKD patients. Scientific exercise rehabilitation training is beneficial to increase exercise tolerance, strengthen skeletal muscle and reduce muscle atrophy in CKD patients; relieve their negative emotions such as anxiety, improve appetite, reduce the inflammatory state of the body and improve nutritional status; reduce the occurrence of hypertension, hyperlipidemia, hyperglycemia and other risk factors; improve cardiovascular function as well as reduce the risk of cardiovascular death; and slow down the pre-dialysis CKD patients’ The quality of life of CKD patients can be improved by slowing down the progression of renal function. Therefore, scientific exercise is very necessary for CKD patients. The exercise program for patients with CKD must be conducted under the guidance of a physician, preferably a team of physicians including a nephrologist, geriatrician, exercise rehabilitator, nurse practitioner and dietitian. The program must be preceded by an assessment that includes evaluation of the kidney disease, cardiopulmonary function, exercise capacity testing, quality of life assessment and psychological assessment. During the patient’s exercise, the patient’s heart rate and blood pressure changes need to be detected, and for patients with heart disease, ambulatory electrocardiogram changes can be monitored. After exercise, patients need to be regularly assessed for kidney disease, cardiopulmonary function, blood lactate level and physical muscle strength changes, which can provide timely feedback on problems and adjust exercise rehabilitation program. In the choice of exercise, first of all, anaerobic exercise is not suitable for patients with kidney disease. Anaerobic exercise often requires breath-holding, which is prone to the climbing of patients’ blood pressure and heart rate; anaerobic exercise is prone to lactic acid accumulation, and patients with kidney disease have a low glomerular filtration rate, and patients have a higher risk of lactic acidosis and electrolyte disorders after strenuous anaerobic exercise. Aerobic exercise is a more appropriate exercise program. For patients who meet the criteria for cardiorespiratory fitness and physical strength assessment, one of the following exercise prescriptions can be tried under medical guidance: 1) brisk walking for 30 minutes 3-5 times per week; 2) jogging or swimming or bicycling for 20 minutes 2-3 times per week. In addition, it is highly recommended that patients with kidney disease perform the traditional Chinese medicine health exercises “Ba Duan Jin” 1-2 times a day for 30 minutes each time. The “Eight Duan Jin” is a total of eight movements, each of which is carefully arranged according to the theory of meridians and acupoints and internal organs of Chinese medicine, and is easy to learn, and has the effect of relaxing the muscles and channels, exhaling and breathing, regulating the five organs, strengthening the kidneys and waist, etc. It is highly recommended by many Chinese medicine practitioners, and is especially suitable for long-term health care and strengthening of middle-aged and elderly patients with chronic diseases.
