Is it rest or exercise? That's how things always go. How many years are there in a cycle (forgetting, resurrection, focus, hot spot, calm, calm, forgetting), and so on. It has been several years since sports re-entered people's sight and became the focus. There is no doubt that laid-off and retired sisters and grandmothers set off this wave. Their masterpiece is square dancing. This trend is obviously dominated by the young middle class, who have turned sports into a colorful fashion. Of course, the Internet and WeChat are very helpful tools. The thinking habit of linking exercise with health has a long history, but this time this connection is more deeply rooted in people's hearts, so when talking about health, we must emphasize exercise. There are many similarities between people and things, that is, inertia, which also follows one of Newton's three laws: constancy is eternity and motion is eternity. People who like sports can't stop, and quiet people don't want to exercise. Many people who like sports or rest are lazy, not for other reasons.
? Rest or exercise When a thing or a phenomenon becomes the focus, there will be different voices competing for the front row position. What is the best exercise? Is it better to rest or exercise? According to the doctor's thinking habit, to answer this question, there must be evidence, not imagination. In the method of evidence-based medicine, reviewing past experience is not enough to fully explain the problem. This requires "prospective, parallel, controlled, double-blind, random and open research".
Generally speaking, if we have to compare which method is better, we need to do observation and control research. For example, from now on, find a group of people and divide them into two groups according to the principle of statistical randomness: exercise group and rest group. Randomization is not random. A random number statistics table is needed to "arrange" which group a person belongs to, rather than which group he wants to belong to according to his wishes. Of course, there are also relatively simple methods, such as tossing a coin, one in front and one in the back. After grouping, one group continued to exercise and the other group continued to rest. The advantage of this grouping comparison is that the age, sex, occupation, health status and eating habits of the two groups are as same as possible, and only the contribution of exercise to health is compared. Through decades of research, this paper analyzes the differences between the two groups in life expectancy, physique, social ability and happiness index, so as to answer whether it is better to exercise or rest.
