Walking slowly can only be said to be much better than not exercising. If you want to lose weight, you'd better run. Because the advantage of running is that it is good for all parts of our body. The first is the lungs. Running can increase our capillaries and improve the oxygen utilization level. According to research, the oxygen uptake of a professional athlete is 80ml per kilogram of body weight, which is a ratio, that is, 80ml per kilogram of body weight, which is the frequency of a professional athlete. Ordinary people have not gone through long-term exercise, and their oxygen intake is only 40ml of that of professional athletes. However, if you persist in jogging for a long time, the oxygen intake per kilogram of body weight can reach 60ml. This shows that if you are a jogger, your body contains more oxygen than ordinary people. Sometimes you feel so tired that you can't breathe because the oxygen content in your body has dropped. Let's do an experiment. Seeing the word yawn, many people are easily influenced. If you want to yawn, it means that your blood oxygen content is not enough.

The second is the impact on the cardiovascular system. When you can keep running for a long time, the volume of your heart will increase, and the quiet pulse and exercise pulse will decrease. The quiet pulse is the normal pulse, and the exercise pulse is the pulse after running. They will all decrease, the speed will decrease and the elasticity of blood vessels will increase. Many elderly people around us are fragile and easy to rupture, so vascular elasticity is very important. Thrombosis and arteriosclerosis, blood lipids will drop, and our heart pressure will decrease.
