The metabolism of the body is accelerated during exercise, and the accelerated metabolism needs to consume more energy. The energy of human body comes from the catabolism of sugar, protein and fat. When there is not much exercise, such as jogging, the energy supply of the body mainly comes from the aerobic metabolism of sugar. When the exercise we are engaged in is very intense or explosive, the body needs a lot of energy in an instant, but under normal circumstances, aerobic metabolism can't meet the needs of the body at this time, so sugar quickly produces a lot of energy through anaerobic metabolism. Exercise in this state is anaerobic exercise. By comparing the two kinds of exercise methods, it is concluded that the way out is the lowest fitness efficiency.
Running can only enhance the body's immunity and speed up blood circulation, but it can't exercise the muscles of the effective parts of the body.
If you want to develop your muscles, you need to do related exercises through anaerobic exercise, that is, strength training. Running, an aerobic exercise, allows our bodies to take in enough sugar and protein, so that our bodies will not gain weight again and keep a good figure, so that our cardiopulmonary activities will be stronger and our immunity will be stronger. However, it is not a targeted activity. For example, if we exercise abdominal muscles, we should have corresponding professional equipment and special movements to exercise.
We can usually take running as an important way of life exercise, because its cost is very low and there are basically no obstacles. As long as you want to stick to a smooth road, it is enough to provide people with running space. Although its exercise effect is not as obvious as anaerobic exercise, your persistence for many years can make your heart and lung function stronger and your body immunity stronger, which is of great benefit to maintaining our health.
Although running is the least efficient way to keep fit, it is the best exercise to keep healthy. In order to be younger and more energetic, come and run!
