Although the whole earth is no longer free from pollution and radiation, we still hope to live a long life. The following are all proven ways to live a long life. I understand after reading them: to live a long life, you must be a big pervert with a very high educational background, a very short stature, a little food, a lot of exercise, a love of whole grain food, a complete lack of adventure, a baby face, a decision to practice late childbirth, a walk of tiger and tiger, but a very curmudgeon with a long life gene! Let’s look at why.
a quick walker has a long life.
According to a research report published in the Journal of the American Medical Association (JAMA) on January 5, the elderly who walk faster live longer.
Background data: the life expectancy of the elderly varies greatly. Doctors should take life expectancy into account when assessing the goals of health care and treatment programs. However, life expectancy based on age and gender alone is not very accurate, because health and physical function also affect the length of life. However, none of the current life expectancy prediction methods include health and physical function.
Stephanie, M.D. and master of public health from the University of Pittsburgh, and her colleagues carried out the study. The purpose of the study was to reveal the relationship between walking speed and life span of the elderly, and to determine the impact of walking speed on life span. The original data of the study included data analysis from nine research projects, which were collected from 1986 to 2000, and the study subjects were 34485 elderly people aged 65 or above. The researchers tracked the walking speed of these elderly people for several years, and all the records followed two principles: 1. They measured the daily walking speed; 2. Walk from standing. The data showed that the average life span of the subjects was 73.5 years, and the average walking speed was 0.92 meters per second.
During the study, 17528 elderly people died. Among them, from the beginning of the study, about 84.8% of the elderly had a residual life of 5 years or more, and 59.7% had a residual life of 10 years or more. Researchers found that the remaining life of the elderly with the same age and the same sex was related to the walking speed, which was especially obvious in the elderly group over 75 years old.
In most age groups, the walking speed of the elderly with the median life expectancy is about 0.8 m / s, both for men and women; On the premise of consistent gender and age, the faster the walking speed, the longer the life expectancy. The life expectancy of the elderly with a walking speed of more than 1m / s will be longer than that when only age and gender are considered. In many age groups, the walking speed of the elderly is proportional to the remaining life, and the younger the age, the greater the absolute value of the expected remaining life.
Why can walking speed predict life span? This is because walking needs to consume body energy and effectively control limb movements, as well as the support and cooperation of multiple organ systems, including the cardiopulmonary system, circulatory system, nervous system and musculoskeletal system. On the one hand, the slow walking speed reflects that the elderly’s body system has been damaged, on the other hand, it also indicates that he / she needs more energy to walk, so the walking speed can predict the elderly’s life.
Researchers said that walking speed has a wide range of clinical effects, including helping to determine which people will have a remaining life of 5 years or more and which people have a greater risk of early death. For people at high risk of early death, we can conduct further physical examination to determine their health problems, so as to treat them targeted. In addition, long-term monitoring of walking speed can help find new problems in the body.
