(1) Avoid abdominal pain when running. Many people often have upper abdominal pain or left and right upper abdominal pain when running, especially in the early morning. Medical experts believe that this is related to human respiratory muscle spasm. Respiratory muscles in human body mainly include diaphragm and intercostal muscle. If the diaphragm spasms, it will cause pain in the upper abdomen or left and right upper abdomen. When running, human organs will transition from a quiet state to a moving state. At this time, the metabolic process in the body is vigorous, the demand for the atmosphere and various nutrients suddenly increases, and the metabolic products of the human body are also accelerating excretion, which requires the respiratory system and cardiovascular system to improve work efficiency. However, because the function of internal organs can not be adjusted to the required state immediately, there is a contradiction between the moving organs and internal organs, and the respiratory system of the human body will speed up the breathing frequency and increase the breathing depth. People who have just started to practice long-distance running often only pay attention to increasing the breathing frequency, but ignore adjusting the breathing depth, which leads to the acceleration of the contraction frequency of breathing muscles and the tension of breathing muscles, thus causing spasms. The spasm of respiratory muscles can directly stimulate sensory nerve endings, thus making people feel pain. Experts suggest that warm-up exercises should be done carefully before running to prevent this phenomenon. Through warm-up, the internal organs of the human body can gradually enter the state of exercise. Running again at this time can avoid stomach pain, and even if there is stomach pain, the symptoms will be mild.

(2) Self-treatment of exercise-induced abdominal pain Nowadays, more and more people like physical exercise, but some people often have abdominal pain during exercise, which is medically called "exercise-induced abdominal pain" and should be paid attention to. Abdominal pain after exercise can be caused by the following reasons, and different treatment methods can be adopted according to different situations.

1, insufficient preparation activities. At the beginning of exercise, because the function of internal organs has not been improved to the proper level of exercise, the intensity of exercise is increased, especially the poor myocardial strength and weak pulse, which affects the venous blood return, the pressure of inferior vena cava is increased, and the hepatic venous return is blocked, thus causing liver and spleen congestion and swelling, increasing the tension of liver and spleen capsule, and producing related pain. To prevent this kind of exercise-induced abdominal pain, the key is to make full preparations before exercise to adapt the internal organs.

2, gastrointestinal spasm. Abdominal pain is caused by gastrointestinal spasm during exercise, ranging from dull pain, swelling pain to paroxysmal colic, in severe cases. The pain is mostly around the navel and upper abdomen. When this kind of abdominal pain occurs, you can apply hot compress on the abdomen to relieve spasm. The preventive measure is not to eat too much before exercise, and not to eat gas-producing foods such as beans, potatoes and cold drinks.

3, rectus abdominis spasm. Most of them happen in summer. During strenuous exercise, due to a large amount of water and salt loss, metabolic disorder and fatigue in the body can cause spasmodic pain in rectus abdominis. The key to prevention lies in properly supplementing saline when sweating during summer exercise, locally massaging rectus abdominis and stretching rectus abdominis to relieve abdominal pain.

4, respiratory rhythm disorder. When doing a lot of exercise, it destroys even and rhythmic breathing, reduces oxygen intake, causes hypoxia in the body, and leads to respiratory muscle fatigue. After diaphragm fatigue, the massage effect on the liver is weakened, which leads to congestion and swelling of the liver and abdominal pain. For this kind of abdominal pain, the key is to adjust the breathing rhythm and try to breathe through the nose instead of opening your mouth. References:
