Doctors at Peking Union Medical College say: Are you working out like crazy? Be careful! Your fatty liver may not be able to handle it.

During Mr. Wang's physical examination last year, he was not only found to be overweight but also to have moderate fatty liver and abnormal liver function. In order to take off the "hat" of fatty liver, Mr. Wang went to the gym to perform high-intensity sprinting, equipment training and other anaerobic exercises. I thought that I could get a healthy body in return for my sweat, but unexpectedly, the physical examination result was still fatty liver, and the abnormal liver function indicators were even worse than before. Mr. Wang was confused. How could his hard exercise backfire? Now, let the medical staff of the Department of Health Medicine of Peking Union Medical College Hospital tell you what happened——

In fact, high-intensity exercise for patients with fatty liver, especially those with impaired liver function, not only fails to achieve the purpose of recovery, but may also cause damage to the body. This is mainly because excessive exercise can cause peripheral blood flow to be redistributed, resulting in insufficient blood supply to the liver, causing accumulation of metabolites and toxins in the body, which is not conducive to the recovery of liver function and may even aggravate liver damage. In addition, not all types of fatty liver can be improved through exercise. In addition to fatty liver caused by overnutrition, long-term drinking may also be the "black hand behind the scenes". For fatty liver caused by long-term drinking, the first thing to do is to quit drinking.

For patients like Mr. Wang who have fatty liver due to overnutrition, the prerequisite for treatment is fat loss. First of all, they should have a low-fat diet and exercise moderately. When formulating exercise therapy, patients with fatty liver should choose the appropriate exercise method based on their condition, obesity level, age, etc. The intensity should be gradually increased and not reckless.

According to the research of China Sports Science Society, the most effective way to burn fat is not short-term high-intensity anaerobic exercise, but long-term medium-to-low-intensity aerobic exercise, such as brisk walking, jogging, cycling, playing badminton, kicking shuttlecock, yoga, radio gymnastics, swimming, etc. The heart rate should be maintained at at least 100 beats per minute during exercise, but not more than 170 times per minute minus age (such as 170-40=130 times for 40 years old). Each exercise time is preferably 30 to 60 minutes. After exercise, there is a slight sense of fatigue, but the mental state is good, the physical strength is sufficient, the sleep is good, and the appetite is good, which means that the amount of exercise is appropriate, and it is appropriate to exercise 5 times a week.

Special Tips

Many people go to the gym to train hard before the physical examination in order to make all the physical examination indicators normal. Some long-distance running enthusiasts even participate in marathons before the physical examination. However, after the physical examination results come out, the blood test shows that the indicators such as creatine kinase, lactate dehydrogenase and transaminase are elevated. The reason is that high-intensity exercise can easily lead to muscle damage, damage to the muscle cell membrane, and a large amount of components in the muscle cells are released into the blood. The recovery time of muscle damage takes more than 2 days. Therefore, it is recommended that you avoid high-intensity exercise 3 days before the physical examination.
