Running every day can certainly improve physical fitness, running belongs to aerobic exercise, beneficial to all parts of our body. The first is the lungs, running can make our lung capacity increase, increase the level of oxygen utilization. According to research, a professional athlete's oxygen uptake is 80ml per kilogram of body weight, which is a ratio of 80ml of oxygen uptake per kilogram of body weight, the frequency of a professional athlete. Ordinary people without long-term exercise, the oxygen uptake is only half of the professional athlete 40ml. however, if you persist in jogging for a long time, the oxygen uptake can be up to 60ml per kilogram of body weight. This means that if you are a jogger, the oxygen content in your body is more than that of an ordinary person. Sometimes you feel tired and can not breathe up, is because of your body's oxygen content decline. Let's do an experiment, when you see the three words yawn, many people are easily affected, all want to yawn, which means that the blood oxygen level in your body is not enough. The second is the impact on cardiovascular, when you can run for a long time, the volume of the heart will increase, the quiet pulse and the exercise pulse will fall, the quiet pulse is the normal pulse, the exercise pulse is to run up after the pulse, they will fall, the speed will fall, and the elasticity of the blood vessels will also increase. Many of the older people around us in their later years have fragile blood vessels that rupture easily, so blood vessel elasticity is important. Blood clots and atherosclerosis and lipids all go down, and the pressure on our hearts is reduced. We also want to remind you that morning running is not the same as getting up in the middle of the night to run, this is not right and not safe, it is recommended that you run in the morning when the sun rises the effect is the best, please adopt it.
