China's health care experts also put forward that "it is better to practice than to walk", and the effect of fitness and health care is by no means worse than practicing martial arts hard. Some people despise the efficacy of walking exercise. They think that only strenuous exercise that makes people sweat and gasp can have the benefits of fitness. Actually, it is not. Excessive exercise is called "anaerobic metabolism" in medicine, which brings more or less consumption and wear to life, especially to the elderly.
A research report shows that long-term slow exercise is far more effective than short-term strenuous exercise. In fact, walking helps to strengthen myocardial function, control blood sugar, reduce bad cholesterol, restore the elasticity of hardened blood vessels, promote metabolism and enhance immunity. Walking all the year round also helps to release a chemical substance in the body, which not only makes people feel happy, but also prevents Alzheimer's disease.
The daily walking time is not less than half an hour and the distance is not less than three kilometers. The pace of healthy young people can reach two steps per second; Patients with chronic diseases and the elderly should take 1 step per second or 80 steps per minute. Don't wear tights when walking, not at night, in dense fog or in poor air.
To sum up, walking is actually very beneficial to people's health, especially for the elderly who are not suitable for strenuous exercise. You can choose to exercise by walking, and long-term persistence will also bring great benefits to the health of the elderly. Especially pregnant women, you can also take a walk to exercise. At the same time, the most important thing is persistence. Remember not to fish for three days and dry the net for two days.
