What is the ratio of a person s age and running speed

People in the 30-39 age group do not reach kilometers in 12 minutes, indicating that the level of exercise is poor; If you can reach kilometers, it means that the level of exercise is good; If you can exceed the kilometer, you will reach an excellent level of exercise. In the 40-47 age group, those with poor exercise levels run within kilometers every 12 minutes; The good ones are kilometers; The excellent ones are more than kilometers. Those over the age of 50 who are poor, good, and excellent run the distance every 12 minutes within kilometers, kilometers, and kilometers or more, respectively.

It is impossible to achieve the desired results in the short term, and only regular exercise will improve the level of exercise. If you only run once a week, you won't have much benefit from running longer distances. Because in the six days of the hiatus, the body's tissues have exhausted the benefits of running.

Therefore, run no less than three times a week. People who don't exercise regularly tend to exercise too much once they decide to start exercising regularly, which can lead to undesirable consequences.

Peking Man still retains some of the physical characteristics of apes, but they have been able to stand up and walk, and their upper limbs basically have the characteristics of modern humans. The hand is the organ of labor, which develops faster and becomes flexible and light. The lower limbs are used to support the body and stand up and walk, and develop more slowly.

With the differentiation of limbs and the development of hands, the brain is also slowly restocking. This change shows that labor played an important role in the process of purchasing goods from apes to humans.

In the early stage, it is directly proportional, because of age, physical development, stride length, cadence will increase, and walking more and more steady.

In the mature stage, that is, the adolescent stage, it is generally proportional to the growth, and then slowly remains stable.

In middle age, the body begins to decline, showing a certain downward trend, and even a significant decline.

In old age, physical fitness generally declines relatively quickly, inversely proportional.

Of course, due to the different physical qualities of individuals, the environment will be different, but most of them are proportional first, equal in the middle, and then inversely proportional.

A person's age is directly proportional to their running speed, and refers to young students, middle or high schools, colleges, and athletes.

A person's age is inversely proportional to their running speed and refers to the elderly.

Maybe it's proportional, it's a rule that you run slower and slower as you get older. The best exercise is walking.
