The early morning sun shone on the runway in the suburbs, and Li Ming was running the ten kilometers he had to do every day at a steady pace.
As a veteran marathon enthusiast, he has participated in marathons around the world for five consecutive years and finished with flying colors. Li Ming has always believed that running is the best exercise to strengthen the body and prevent various diseases.
But just yesterday, he suddenly received a phone call that puzzled him.
On the other end of the phone was his friend Dr. Zhang, who had been his friend for many years, with a little worry in his tone: "Lao Li, there is a new study recently, you have to pay attention." Studies have found that people who love to run are more likely to suffer from heart and brain infarction than people who don't. You love running so much, I think you should know about it. "
Li Ming was stunned for a moment after hearing this, this news was like a bolt from the blue for him. He couldn't help but ponder: Could it be that the running habit he had always been proud of was a health hazard? What the hell is going on?
Full of questions, Li Ming decided to dig deeper into the study. He contacted Professor Wang from the local Institute of Sports Science, hoping to get a professional answer.
Professor Wang received Li Ming and patiently explained to him the ins and outs of the study. It turned out that the study was completed by a cardiology team from a well-known medical school affiliated hospital, and they followed 3,000 long-term marathon enthusiasts for a period of 5 years. The results of the study showed that compared with the people who do not exercise regularly, the incidence of cardiovascular and cerebrovascular diseases in these runners is significantly higher.
"This study has indeed attracted a lot of attention from the medical community. But we also have to look at this result dialectically. There's no doubt that excessive exercise can have a negative impact on the body. But that doesn't mean running is inherently harmful. "
Li Ming was thoughtful after hearing this. He remembered his running friend Xiao Zhang, who had just been hospitalized for acute myocardial infarction some time ago. At that time, everyone was surprised to think that a person who runs marathons often could get this disease. Now it seems that it may really be related to excessive exercise.
In order to learn more about the situation, Li Ming visited Dr. Zhao, director of the cardiology department of a local tertiary hospital. Dr. Zhao is an authoritative expert in this field, and she gave detailed answers to Li Ming's questions.
Dr. Zhao explains, "Long-term excessive exercise may indeed increase the risk of cardiovascular and cerebrovascular diseases. This is mainly because high-intensity exercise can lead to increased blood viscosity and increased platelet activity, which increases the risk of thrombosis. In addition, long-term high-intensity exercise may also cause myocardial fibrosis and increase the incidence of arrhythmias. "
Dr. Zhao also presented Li Ming with a study by a Chinese scholar published in the Chinese Journal of Cardiovascular Diseases. The study followed 1,000 long-distance runners for 3 years and found that about 5% of them had varying degrees of abnormal heart function. This proportion is much higher than that of the general population in the same age group.
After listening to Dr. Zhao's explanation, Li Ming was shocked and confused. He couldn't help but ask, "Shouldn't we run?" Is exercise really bad for your health?"
Dr. Zhao smiled and shook his head: "No, we definitely can't come to such a conclusion. The health benefits of moderate exercise are undeniable. The key is how to grasp the 'degree'. "
Dr. Zhao suggested that Li Ming could adjust his exercise plan appropriately. She recommends Li Ming to run 3-4 times a week for 30-45 minutes each time, at a moderate intensity. At the same time, she also reminded Li Ming to pay attention to his body's signals and stop exercising immediately if he feels unwell.
Li Ming realized. He remembers that in preparation for the marathon, he often overloads his training, sometimes running twice a day. Now it seems that there are real risks associated with this approach.
In order to further verify this view, Li Ming contacted several friends who have been running for a long time. Some of them reported that they did have symptoms such as irregular heartbeat and chest tightness, while others said that everything was normal. This reinforces the importance of individual differences.
After in-depth understanding, Li Ming has a new understanding of this issue. He realized that movement was indeed a double-edged sword. Moderate exercise can enhance cardiopulmonary function, improve blood circulation, and reduce the risk of cardiovascular and cerebrovascular diseases. However, excessive exercise can be counterproductive and increase the risk of disease.
Li Ming decided to adjust his exercise plan. He no longer blindly pursues the amount of running, but pays more attention to the quality of exercise and the feeling of the body. He began experimenting with other forms of aerobic exercise, such as swimming, cycling, etc., to make his exercise more varied.
Li Ming also began to pay attention to his diet and rest. He learned that proper nutrition and adequate rest are essential for recovery after exercise. He began to replenish protein and carbohydrates in time after exercise and guaranteed 7-8 hours of sleep a day.
Li Ming's change has attracted the attention of runners. Everyone asked him for advice, hoping to find a way to exercise that suits them. Li Ming shared the information he learned with everyone and encouraged everyone to make a reasonable exercise plan according to their own situation.
Gradually, Li Ming found that his physical condition had improved significantly. He no longer felt overly tired, but felt more energetic. His heart rate has also stabilized and his blood pressure has remained within the ideal range.
This experience made Li Ming deeply realize the importance of the scientific movement. He began to pay more attention to the latest research in the field of sports medicine and had regular check-ups to monitor his physical condition.
Li Ming's story has sparked social attention to the science movement. More and more people are realizing that exercise is not about the more the better, but about being reasonably arranged according to individual circumstances. Many gyms and sports centers are starting to offer personalized exercise coaching services to help people find the best way to work.
The medical community has also conducted more in-depth research on this issue. Some hospitals have begun to offer special health check-ups for long-term exercisers to help them identify potential health risks in a timely manner. At the same time, some researchers have begun to explore how to use technology to more accurately monitor exercise intensity and body response.
This discussion on exercise and health not only raised public health awareness, but also promoted the development of the field of sports medicine. People are beginning to look at exercise more rationally, neither blindly pursuing nor choking.
Li Ming's experience tells us that a healthy lifestyle requires scientific guidance and personalized arrangements. Exercise is indeed an important means to maintain health, but the premise is that we understand our body, respect science, and arrange reasonably. Only in this way can we truly benefit from exercise and enjoy a healthy and beautiful life.
