What are the effects and functions of aerobic running on the human body?

Everyone knows that aerobic running is a sport that is very beneficial to human health. So what are the effects of aerobic running on the human body? Let's take a look.

The effects of aerobic running on the human body

1. Effects on the cardiovascular system

Aerobic exercise can enlarge the heart chamber, increase the stroke volume, slow the heartbeat, prolong the diastole of the heart, and allow the heart to get more rest and work more sustainably. With the enhancement of the cardiovascular system, the capillaries, the blood channels in the human body's periphery, increase the blood supply, and provide convenient conditions for the body's oxygen transport, thereby improving the endurance of skeletal muscles and preventing fatigue. In addition, aerobic endurance exercise plays an important role in lowering blood lipids, stabilizing blood pressure, and treating and preventing cardiovascular diseases.

2. Effects on the respiratory system

Long-term aerobic fitness running exercises can exercise the respiratory muscles during running, increase the strength of the respiratory muscles, and increase the depth of breathing; it can also increase the adaptability of lung capacity, expand lung ventilation, and reduce the number of breaths. Ultimately, it can improve the respiratory function reserve and also improve the oxygen utilization rate of participants.

3. Effects on the nervous system

Fitness running is the result of regular and coordinated movements of all parts of the human body. Long-term running can significantly improve the functions of nerves such as excitement and inhibition, conduction and reaction, and significantly enhance the body's ability to adapt to the outside world.

4. Effects on muscles and bones

Aerobic running can improve muscle fullness, increase the activity of oxidase in mitochondria, and improve the ability of skeletal muscle to work for a long time. It can also improve body shape, enhance joint flexibility, improve bone structure, promote bone development in adolescents, and slow down osteoporosis in the elderly.

5. Effects on liver function

When people run, the consumption of sugar in the body increases, which in turn increases the liver's sugar supply capacity. Therefore, long-term fitness running can improve the liver's working capacity. Experiments have shown that people who have been engaged in fitness running for a long time have higher liver function than the average person, stronger resistance to disease, and are more economical in using liver glycogen than the average person.

6. Psychological impact

Studies have shown that long-term aerobic exercise can improve adverse psychological conditions such as trait anxiety, depression, and schizophrenia. The timing of physical exercise is very important. Each exercise must last more than 20 minutes, and it will take at least ten weeks to significantly reduce trait anxiety. The results of a test conducted by North et al. showed that both one-time physical exercise and long-term physical exercise can effectively reduce depression, and this effect is most obvious in subjects who need special psychological care.

7. “Runner’s High”

This experience is the climax that occurs during running, also known as "exercise high". This state is a kind of joy and high that is experienced in a moment while running (or other sports), and usually appears suddenly and unexpectedly. When it appears, the runner feels a good physical and mental state, and he or she is integrated with the scene, the body is relaxed, forgets himself or herself, is full of passion, and even transcends the barriers of time and space to experience a smooth experience!
