According to a new survey, keeping a long-distance slow walking habit can prolong life. The study also points out that running for too long and too high intensity will not bring obvious benefits to people’s life span. “The life-span health bell curve tells us that moderate exercise can maximize health.” Said Dr. Peter schnohr of Frederiksberg hospital in Copenhagen.
Researchers believe that the mechanism of moderate exercise on cardiovascular health and life extension may be different from that of high-intensity exercise program on cardiopulmonary function and physical function.
This result is based on 1098 healthy people with the habit of jogging and 3950 healthy people without the habit of jogging in Copenhagen. In the total sample, 9% of the people were over 50 years old. However, the number of deaths in the jogging population was 28, while there were 128 in the other group. They divided the people with the habit of jogging into mild joggers, moderate joggers and highly ramblers according to their exercise intensity. The results of correlation analysis show that those who do not walk for 1 to 2.4 hours have the lowest mortality rate, and are 71% lower than those who do not walk. Those who walked for less than one hour a week were also 53% less than those who did not walk. Interestingly, the mortality rate of those who ran for 2.5-4 hours per week did not change significantly compared with those who did not walk.
In fact, this study is not the first to suggest that excessive exercise will not improve health. In 2012, Dr. duck Chul Lee of Ohio State University and Dr. Carl Lavie of New Orleans proposed that short distance exercise is the most helpful for health. They also put forward the so-called clock shaped money withdrawal: after the amount of exercise exceeds a certain value, the health level of the body does not rise but falls. Two years later, another study reported by the same research group found that jogging for 5-10 minutes a day could significantly reduce the risk of death from cardiovascular disease and other diseases. The study at Cooper clinical center in Dallas included 55137 adults and was followed up for 15 years.
Dr. Lavie proposed that although this study reported the benefits of low-intensity exercise on human health, it did not get clear evidence that high-intensity exercise was harmful to human health. He also explained why people are willing to run more, including mental health, improving the level of running, reducing fat, or eating more. But these reasons have nothing to do with health or longevity. In addition, even if high-intensity sports have certain risks, the risks are relatively small on the whole, especially for sports, they originally paid more attention to performance and competitive level. In other words, exercise to improve the body’s optimal exercise state is not suitable for a long-term health plan. This also reminds doctors and patients that high-intensity exercise is not necessary for physical health.
