(A) the role of indoor running in situ
Running indoors in situ is more intense than walking in situ, which is more conducive to improving the functions of organs such as the whole body, lung system and metabolic system.
1. Promote the function of cardiovascular system
It is observed that people who run for a long time, the blood volume pumped by the heart increases, the heart rate decreases correspondingly, and the heart function is enhanced; Coronary artery blood supply function is better than hinge, and myocardial metabolism function is normal. Can prevent ischemic heart disease. The continuous contraction of lower limb muscles improves blood circulation and can effectively promote the blood return of lower limb veins and pelvic and abdominal veins; Thereby preventing thromboangiitis and hemorrhoids.
2. Promote the function of respiratory system
When running, the amount of air inhaled is several times more than when sitting, so that the lungs can be fully active, which can effectively prevent the elastic function of lung tissue from decreasing, improve the ability of human body to carry and utilize oxygen, and increase respiratory efficiency.
3. Promote the metabolic function of the body
Running can consume more energy, and muscles do work for a long time, naturally consuming body fat and increasing muscles. This is very beneficial to lose weight, control weight and prevent obesity. In addition, running can also speed up blood flow, greatly reduce excessive cholesterol and triglycerides in serum, improve lipid metabolism, prevent hyperlipidemia, and help prevent arteriosclerosis and coronary heart disease.
4. Similar to the effect of foot massage
According to the meridian theory of traditional Chinese medicine, there are many starting and ending points of meridian circulation in the sole of the foot, and each point corresponds to a certain part of the body. Stimulating these acupoints can regulate the blood circulation of the corresponding body parts and help to improve or promote the functions of these parts. When running, the soles of the feet can be evenly stressed, and the soles of the feet can be repeatedly stimulated and rubbed to achieve the effect of foot massage.
5. Other functions
Running is a whole-body exercise, and all organs of the body are stimulated through constant exercise, so the effect of running is also multifaceted. (1) Running briskly and rhythmically can make people feel happy, improve the function of nervous system and prevent neurasthenia. 2 Jogging can keep blood pressure normal, thus improving human kidney function. (3) Sweating a lot during running can expel lead, strontium, beryllium and other carcinogens and other harmful substances in the human body to prevent fatty cancer. As American cardiologist Dr. George George Shinn commented, running is a comprehensive exercise of exercise physiology. Running is indeed a sport that can be widely carried out, and indoor in-situ running is also an alternative form of this healthy exercise.
